Purpose: The aim of this study was to evaluate the effect of 4-hexylresorcinol and hydroxyapatite combination graft on bone regeneration in the rabbit calvarial defect model. Methods: Ten New Zealand white rabbits were used for this study. Bilateral round shaped defects (diameter: 8.0 mm) were created on the parietal bone. 4-hexylresorcinol and hydroxyapatite combination graft material was grafted into the right parietal bone defect area (experimental). The left bone defect area was not filled with anything (control). The animals were sacrificed at 4 weeks and 8 weeks after grafting. A micro-computerized tomography of each specimen was taken, and the specimens were stained for histological analysis. Results: The average value of bone mineral density (BMD) and Bone volume (BV) was higher in the experimental group than in the control group at 4 weeks and 8 weeks after surgery. However, the difference was not statistically significant (P>0.05) at 8 weeks after grafting. The BMD and BV in the experimental group at 4 weeks after surgery was significantly higher than those in the control group (P<0.05). Conclusion: 4-hexylresorcinol and hydroxyapatite combination graft material showed higher initial bone formation than the control, however, there was no difference at 8weeks after operation.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 6, 2012, Pages 384~390
Purpose: The purpose of this study is to examine in vivo osteogenesis of cultured human periosteal-derived cells and polydioxanone/pluronic F127 scaffold. Methods: Two one-year-old miniature pigs were used in this study.
periosteal-derived cells in 1 mL medium were seeded by dropping the cell suspension into the polydioxanone/pluronic F127 scaffold. These cell-scaffold constructs were cultured in osteogenic Dulbecco's modified Eagle's medium for 7 days. Under general anesthesia with azaperone and tiletamine-zolazepam, the mandibular body and ramus of the pigs were exposed. Three bony defects were created. Polydioxanone/pluronic F127 scaffold with periosteal-derived cells and the scaffold only were implanted into each defect. Another defect was left empty. Twelve weeks after implantation, the animals were sacrificed. Results: New bone formation was clearly observed in the polydioxanone/pluronic F127 scaffold with periosteal-derived cells. Newly generated bone was also observed in the scaffold without periosteal-derived osteoblasts and empty defect, but was mostly limited to the periphery. Conclusion: These results suggest that cultured human periosteal-derived cells have good osteogenic capacity in a polydioxanone/pluronic F127 scaffold, which provides a proper environment for the osteoblastic differentiation of these cells.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 6, 2012, Pages 391~397
Purpose: The purpose of this study was to evaluate the effectiveness of the platelet-rich fibrin (PRF) used in combination with the porcine cancellous bone as a scaffold, in promoting bone regeneration in the bone defects ofthe rabbit calvaria. Methods: Ten rabbits were used in the study. Three round-shaped defects (diameter 8.0 mm) were created in the rabbit calvaria and were filled with nothing (control group), porcine cancellousbone (Experimental Group 1, porcine bone) and PRF-mixed porcine cancellous bone (Experimental Group 2). TS-GBB is a xenogenic bone-substitute product comprised of a high heat-treated mineralized porcine cancellous bone. Animals were sacrificed at 6 weeks and 12 weeks for the histological and radiographic evaluations. Results: In the micro computed tomography and histological results, the experimental groups 1 and 2 showed more bone formation, remodeling, and calcification than the control group. The new bone formation ratio showed theGroup 2 to be larger than Group 1 at6 and 12 weeks. However, there was no significant difference between the experimental groups 1 and 2 in the new bone formation area, at the 6 and 12 weeks (P>0.05). Conclusion: The PRF-mixed group showed more bone formation than the porcine cancellousbonegroup (TS-GBB), butthere was a no significant difference. The PRF may not lead to enhanced bone healing when grafted with the porcine cancellous bone.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 6, 2012, Pages 398~403
Purpose: Mandible resection and discontinuity defect created lead to aesthetic and functional problems. The iliac crest bone graft exhibits relative ease for bone harvesting, possibility of two team approach, ability to close the wound primarily, large amount of corticocancellous bone and relatively few complications. Whereas the use of free vascularized flaps has donor site morbidity and worse-fitting bone contour, the use of nonvascularized iliac bone graft has advantages in the operation time and patients' recovery time. So, nonvascularized iliac bone graft could be an attractive option. Methods: Twenty-one patients (M:F=1:1.1) underwent iliac crest bone harvesting for reconstruction of mandibular discontinuity defect (mean length :
mm), from May 2005 to October 2011 at the Department of Oral and Maxillofacial Surgery in Kyungpook National University. The average age was
years and the mean follow up periods was
months. Bone resorption rate, according to age, sex, primary lesion, location and distance of defect, type of fixation plate, time of graft and pre-operative radiation therapy, were measured in each patient. Results: The mean bone resorption rate was
. Bone resorption rate was significantly increased in mandibular defect that is over 6 cm in size (P=0.015, P<0.05) and the cases treated pre-operative radiation therapy (P=0.017, P<0.05). All was successfully fixed and maintained for the long-term follow-up. There were a few donor site complications and almost all patients were shown favorable outcome without severe bone resorption in this study. Conclusion: The nonvascularized iliac bone graft seems to be a reasonably reliable treatment option for reconstruction of mandibular discontinuity defects.

Purpose: The purpose of this study was to evaluate postsurgical facial hard tissue stability after orthognathic surgery with/without posterior impaction in skeletal class III malocclusion patients, and to evaluate the horizontal relapse tendency, according to changes in anteroposterior discrepancy and occlusal planes. Methods: Ninety patients, who had undergone orthognathic surgery in Pusan National University Dental Hospital, were enrolled in this study. Three main groups were classified as follows: Thirty patients underwent mandibular setback bilateral sagittal split ramus osteotomy (BSSRO) only (BSSRO group, BG); another thirty patients underwent mandibular setback BSSRO and Le Fort I osteotomy with posterior impaction (posterior impaction group, PG); and another thirty patients underwent mandibular setback BSSRO and Le Fort I osteotomy without posterior impaction (non-posterior impaction group, NPG). Preoperative (T0), immediate postoperative (T1) and six-month follow-up period (T2) lateral cephalograms were taken, and various parameters were measured. The analyses were done by linear and angular measurements between T0-T1 and T1-T2, to evaluate postsurgical facial hard tissue stability. Results: Mean horizontal relapse rates were distributed from 11.81% to 19.08%, and there were significant postsurgical changes (0.52 mm~2.44 mm) at the B point in all 3 groups. But, there were no statistical differences on relapse rate among BG, PG and NPG patients. Conclusion: In this study, the postsurgical stabilities of BSSRO and Le Fort I osteotomy with/without posterior impaction in skeletal class III malocclusion patients were acceptable. There were no significant statistical differences in mandibular stability according to changes in anteroposterior discrepancy and occlusal planes.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 6, 2012, Pages 413~420
Purpose: The purpose of this setback genioplasty study is to develop a prediction method for the calculated osteotomy angle using horizontal and vertical changes as well as to evaluate the proportion of hard and soft tissue changes. Methods: Twelve patients who had received setback genioplasty with other maxillofacial surgery were examined. Three lateral cephalograms were taken just before surgery, immediately after surgery, and 3 months later surgery. A reference line was established to the reference point of the inner most point of the lingual symphysis cortex, incisor tip, and 2nd molar cusp tip. Measuring was conducted from pogonion (Pg), menton (Me), labrale inferius (Li), Mentolabial fold, soft tissue pogonion (Pg'), and soft tissue menton (Me') to the reference lines. Results: In setback genioplasty, the skeletal Pg moved posteriorly 5.07 mm. The ratios of soft tissue to hard tissue movement were 36% posteriorly and 62% inferiorly at Pg', 67% posteriorly and 104% inferiorly at Me', and 34% anteriorly and 164% posteriorly at Li. In reduction & setback genioplasty, skeletal Pg moved posteriorly 4.63 mm and skeletal Me moved superiorly 3.63 mm. The ratios of soft tissue to hard tissue movement were 76% posteriorly and 18% superiorly at Pg', 68% posteriorly and 42% superiorly at Me', and 44% anteriorly, 124% posteriorly at Li. The calculated mean slope angle, based on
ratio, was 61.25 and the measured mean slope angle was 60.17. Thus, the calculated and measured slope angles have a similarity. Conclusion: In setback genioplasty, soft tissue moves posteriorly and inferiorly. In particular, at the Me' and Pg', the inferior movement of the soft tissue is greater than the posterior movement. Also, the predictable results (measured slope angle) after operation can be achieved by the calculated slope angle. Thus, the relationship of soft and hard tissue changes must be considered as the results are predictable.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 6, 2012, Pages 421~425
Purpose: The aim of this study is to compare the soft tissue changes of the midfacial area at the repose position and the natural smiling position for the improvement of evaluation and planning in the orthognathic surgery. Methods: The total of 30 subjects, 15 male and 15 female, were included in this study. The metal point landmarks were placed at the cheek, orbital rim, subpupil, and nasal base. The movements of the landmarks were evaluated at the repose position and smiling position in the lateral and posteroanterior cephalograms. Paired t test and correlation analysis were used for the evaluation of the soft tissue changes statistically. Results: In the lateral cephalograms, the cheek point (4.49 mm in female, 4.87 mm in male) showed the most distant movement. All points presented significant movements, except the orbital rim and nasal base point in male. Cheek point presented significant positive correlation between the horizontal and vertical change in male. Subpupil point presented significant positive correlation between horizontal and vertical change in both male and female. In the posteroanterior cephalograms, the nasal base point (5.41 mm in female, 6.30 mm in male) showed the most distant movement. Subpupil point and nasal base point presented significant movements in both female and male. Nasal base point presented significant negative correlation between the horizontal and vertical change in both male and female. In the lateral and posteroanterior cephalograms, the positional changes of all points presented significant positive correlation with each other in both female and male. Conclusion: The cheek point in the sagittal view and the nasal base point in the frontal view showed the most distant movement on smile. In the sagittal view, the subpupil point and cheek point moved anteriorsuperiorly on smile. In the frontal view, the nasal base points moved laterosuperiorly on smile. In both the sagittal and frontal view, the positional changes of all point were highly correlated to each other. These results may be used in the soft tissue references for the treatment planning of the dentofacial deformity patients.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 6, 2012, Pages 426~431
Purpose: The aim of this study was to evaluate the effect of temporary mandibular advancement devices (MAD) in obstructive sleep apnea (OSA) patients Methods: 28 patients (male 21, female 7) undergoing temporary mandibular advancement device treatment for OSA were selected from 2011.01. to 2012.02. in the department of Oral & Maxillofacial Surgery at SamsungMedicalCenter. Treatment efficacy was determined by polysomnography (PSG) at baseline & after MAD delivery. The response group was defined as >50% Apnea-Hypopnea Index (AHI) reduction plus post-MAD AHI <10, and the non-response group was defined as <50% AHI reduction. The lateral cephalogram was analysed including SNA, SNB, UL, MPH, PAS, PASU, and PAST using V-ceph
(Cybermed, USA). Results: The responsers were 23 patients, and non-responsers were 5 patients. The AHI was significantly reduced with temporary MAD (
) compared with baseline (
) in the response group (n=23). No significant difference was observed between pre MAD and post MAD except SNB on cephalometric analysis. Among 11 patients successfully treated with the temporary device, 9 patients said that using permanent device brings better effect too. Conclusion: These results indicate that the Temporary MAD could not be the only effective tools on OSA but also be used to predict patient's reactivity about permanent appliance treatment. Further studies are warranted to evaluate the relations between temporary MAD and permanent MAD.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 6, 2012, Pages 432~439
Purpose: The aim of this study was to investigate the blood supply to the maxillary sinus in Koreans using computed tomography of the lateral wall of the sinus, and to analyze the data according to demographic data, and to compare our results with previously published research. Methods: One hundred and three patients (males 51, females 52) who visited the dental clinic were evaluated. We investigated the canals with cone-beam computed tomography, and measured the diameter and length from the bony notch of the vascular canal at the lateral wall of the sinus to each of the reference planes. Results: Most types of vascular canal were type I & II (total 72.2%) which were driving through inside the sinus wall. Type IV, V were frequently investigated in 1st premolar and 2nd molar. Mean height; from anterior nasal spine-posterior nasal spine plane to vascular canal was 5.56 mm in 1st premolar, 2.11 mm in 2nd premolar, 0.98 mm in 1st molar, 4.32 mm in 2nd molar; from the basal layer of the sinus was 4.93 mm in 1st premolar, 5.00 mm in 2nd premolar, 6.05 mm in 1st molar, 7.91 mm in 2nd molar; and from alveolar crest, 20.80 mm in 1st premolar, 16.57 mm in 2nd premolar, 14.01 mm in 1st molar, 16.17 mm in 2nd molar. The mean height of the vascular canal of each reference plane showed no significant difference between sex, site (left or right) and age. The mean diameters of the canals were 1.76 mm in male, and 1.50 mm in female. Diameter decreased with age, and tooth site (from 1st premolar to 2nd molar). Conclusion: These results show that the mean diameter of the vascular canal of the maxillary sinus varies according to age, sex, and tooth site, but that the mean height of canal had no significant difference based on these three factors.

Purpose: The purpose of this study was to evaluate marginal bone loss of the alveolar crest on implants with or without guided bone regeneration and variables that have influenced. Methods: The clinical evaluation were performed for survival rate and marginal bone loss of 161 endosseous implants installed with guided bone regeneration (GBR) in 83 patients from September 2009 to October 2010 in relation to sex and age of patients, position of implant, implant system, length and diameter of implant. Study group (n=42) implant with GBR procedure, control group (n=41) implant without GBR technique. Simultaneous GBR approach using resorbable membranes combined with autogenous bone graft or freeze-dried bone allograft or combination. Radiographic examinations were conducted at healing abutment connection and latest visit. Marginal bone level was measured. Results: Mean marginal bone loss was 0.73 mm in study group, 0.63 mm in control group. Implants in maxillary anterior area (1.21 mm) were statistically significant in study group (P<0.05), maxillary posterior area (0.81 mm) in control group (P<0.05). Mean marginal bone loss 1.47 mm for implants with diameter 3.4 mm, 0.83 mm for implants of control group with diameter 4.0 mm (P<0.05). Some graft materials showed an increased marginal bone loss but no statistically significant influence of sex, implant type or length. Conclusion: According to these findings, this study demonstrated the amount of marginal bone loss around implant has maintained a relative stable during follow-up periods. We conclude that implants with GBR had similar survival rate and crestal bone level compared with implants in native bone.

Purpose: Intravenous sedation with midazolam is common in contemporary dentistry. That is effective for anxious patients, but additional analgesic agent needs to be used, because midazolam alone doesn't have an analgesic effect. This study was performed to select an analgesic agent between an opioid agent, and nonsteroidal anti-inflammatory drugs as adjunctives in intravenous sedation with midazolam. Methods: The subjects were 60 patients who visited the Department of Oral and Maxillofacial Surgery, Sacred Heart Hospital, Hallym University, between August 2009 and February 2010. Conscious sedation was performed on 20 patients of 3 groups (control group, ketorolac group, and fentanyl group), who were divided randomly. The analgesic agent was administrated preoperatively. For sedation, vital signs were recorded. After sedation and operation, subjective questionnaires of the patient and operator were implemented. Results: All of the
, blood pressure, and heart rates stayed within the normal range for sedation. The sedation depth and analgesic effect of the ketorolac group and fentanyl group were similar. In the case of sedation depth, 12 patients in the ketorolac group and 14 patients in the fentanyl group had no memory of surgery. In the case of analgesic effect, the visual analogue scale of pain scored 2~3 in 13 patients in the ketorolac group, and 0~2 in 12 patients in the fentanyl group. The satisfaction of patients and doctors was also similar. Conclusion: Considering the management and complication of an opioid agent, non-steroidal anti-inflammatory drugs is more effective than an opioid agent.

Ankylosing spondylitis (AS) is a chronic autoimmune disease mainly involving the axial skeleton. The pathology of the disease is usually found at the sacroiliac joint, and half of the patients experience cervical spine invasion, but eventually, the whole spine is affected. The involvement of the temporomandibular joint (TMJ) in AS has not been investigated very well. A review of the literature revealed that there are only a few studies of TMJ involvement in AS that combined clinical and radiographic examinations. These studies show widely different results, ranging between 4% and 32%. We experienced Bilateral osseous ankylosis of the jaw treated by total alloplastic joint replacement in AS, and offer a case report.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 6, 2012, Pages 462~465
Horizontal and vertical ridge augmentation with implant placement was performed, using a block type of autogenous tooth bone graft in a 37-year old male patient. This material was very useful for the case of severe alveolar bone resorption of a single tooth. After 13 months, excellent bony healing was obtained and final restoration was performed successfully.
Reconstruction of Mandibular Bone Defect Using a Titanium Mesh with Autogenous Particulate Cortical Bone Graft by an Intraoral Approach: A Case Report
Choi, Seok-Tai ; Leem, Dae-Ho ;
Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 6, 2012, Pages 466~472
The loss of mandibular continuity due to trauma, neoplasm, or infection results in major esthetic and biologic compromise. The reconstruction of the mandibular bone defect still poses a challenge to oral and maxillofacial surgeons. There have been a number of variety graft materials. Among them, free block bone graft with rigid fixation has been widely used. However, cases using free block bone grafts may lead to a marked invasion of the donor site, mal-union, and absorption of the block bone. In this respect, particulate cortical bone using a titanium mesh tray can be an effective alternative option in order to achieve a proper bone contour and good oral rehabilitation. We have developed an intraoral approach for the mandibular reconstruction method using a titanium mesh tray with autogenous particulate cortical bone graft.

Warthintumor (WT), also known as adenolymphoma or papillary cystadenoma lymphomatosum, was described in 1895 for the first time. It is a common benign tumor of the parotid glands and the second most common neoplasm of the salivary gland, accounting for 5% to 14% of all parotid neoplasm. A 63-year-old man visited our clinic with the complaint of swelling on the right parotid gland. Physical examination showed a 3 cm, firm, well-circumscribed, painless mass on the right mandibular angle. Computed tomography imaging showed a
cm well-defined cystic mass. WT is histologically characterized by bilayered, oncocystic cell, lymphoid stroma, and cystic space. With these typical cytomorphologic characteristics, the fine-needle aspiration cytology was performed as diagnostic tool before the surgery. The lymphocytes and oncocystic cell were not observed. The lesion was completely excised under general anesthesia. We diagnosed the case as WT, from the surgically excised specimen. We report on the case with a review of the literatures.

Maxillofacial Plastic and Reconstructive Surgery, volume 34, issue 6, 2012, Pages 480~483
Schwannoma is a benign, slow-growing, tumor of the peripheral nerves without specific symptoms, so that early diagnosis may be difficult. Though approximately 25~40% of all schwannomas occur extracranially in the head and neck region, only 1% of schwannomas are reported in the oral cavity. An 18-years-old female patient visited our clinic with a mass on the middle-right-dorsal surface of the tongue slowly growing for 1.5 years. The patient underwent the surgical removal of the neoplasia under general anesthesia. The mass was well capsulated and a cleavage plane was easily found. There was no recidivation during the course of a one-year follow-up. The treatment for schwannoma is surgical excision of the lesion and recurrence after excision of schwannoma is rare. The final diagnosis is made after a histological examination. Differential diagnoses must be made in relation to malignant tumors and in relation to numerous benign neoformations based on epithelial and connective tissues.

Skull base osteomyelitis is a very rare disease that affects the bone marrow of the temporal bone, sphenoid bone, occipital bone. It occurs typically chronic ear canal infections by malignant otitis externa, but some of atypical osteomyelitis have been reported. It most commonly presents old diabetic patients, and have high morbidity and mortality rate if diagnosis and treatment are delayed. However with respect to pain or dysfunction, it appeared similar to the initial symptoms of temporomandibular joint disorder. So frequently, definitive diagnosis is tend to delayed. We have clinical experience that a patient who presented with symptom similar to temporomandibular disorder, and differential diagnosised by skull base osteomyelitis. We will report this case with literature review.

Hemangioma and vascular malformation are the most common benign tumors that are caused by congenitally or traumatic events. Theses tumors represent approximately 1/3~1/4 of all hemangiomas and vascular malformations in the head and neck. There are many forms of treatment for hemangioma and vascular malformation including closed observation, surgery, radiotherapy, laser therapy, steroid therapy, compression, embolization, and sclerotherapy. Ethanolamine oleate is an unsaturated fatty acid salt that has been used as a sclerosing agent because of its excellent thrombosing properties. This paper presents 1 case of intraoral multiple venous malformations treatment with 1.25% ethanolamine oleate (3.6~9.6 mg dose) intralesionally injected for 6 to 14 weeks over 2 week intervals. After the sclerotherapy, lesions almost completely disappeared without side effects. In conclusion, sclerotherapy using ethanolamine oleate is very effective against venous malformations, and sufficiently provides alternative support for surgical and other methods.

Traumatic lacerations are common in the orofacial region as a result of accidents. Due to the frequent movement of the skin around the mandible, scars in that area are more likely to widen or become hypertrophic. Treatment of facial laceration was performed on three patients and followed by regular check-up. It was discovered that the scars have become hypertrophic, so steroid injections were used. The results were satisfactory with the decrease in sizes and hardnes of the scar. Facial scarring is a particularly distressing phenomenon and has always been a challenge to treat as the scars are more likely to widen or become hyphertrophied due to the frequent movement of the muscle in the facial area. We confirmed that the positive effect of steroid on hypertrophic scars. So, we suggest that proper treatment and periodic follow-up, adjuvant treatments especially steroid injection is necessary in patients with lacerations.

The odontogenic keratocyst (OKC) was originally classified as a developmental cyst, and OKC is histologically divided into orthokeratic and parakeratic types. According to revised histopathological classification of odontogenic tumors by the World Health Organization (2005), the term, keratocystic odontogenic tumor (KCOT) has been adopted to describe parakeratic OKC. The KCOT is noted for its capacity to recur after treatment. The aggressive, or potentially aggressive, nature of KCOT has led to alternative treatments. Among the treatments is noted the use of Carnoy's solution as adjunctive intralesional therapy having a low rate of recurrence. This study suggests a possible benefit of Carnoy's solution against recurrence of KCOT.
