Purpose: This study evaluated the capability of bone formation with silk fibroin/nano-hydroxyapatite/corn starch composite scaffold as a bone defect replacement matrix when grafted in a calvarial bone defect of rabbits
. Methods: Ten New Zealand white rabbits were used for this study and bilateral round-shaped defects were formed in the parietal bone (diameter: 8.0 mm). The silk fibroin 10% nano-hydroxyapatite/30% corn starch/60% composite scaffold was grafted into the right parietal bone (experimental group). The left side (control group) was grafted with a nano-hydroxyapatite (30%)/corn starch (70%) scaffold. The animals were sacrificed at 4 weeks and 8 weeks. A micro-computerized tomography (
) of each specimen was taken. Subsequently, the specimens were decalcified and stained with Masson's trichrome for histological and histomorphometric analysis. Results: The average
and histomorphometric measures of bone formation were higher in the control group than in the experimental group at 4 weeks and 8 weeks after surgery though not statistically significant (
>0.05). Conclusion: The rabbit calvarial defect was not successfully repaired by silk fibroin/nano-hydroxyapatite/corn starch composite scaffold and may have been due to an inflammatory reaction caused by silk powder. In the future, the development of composite bone graft material based on various components should be performed with caution.

Maxillofacial Plastic and Reconstructive Surgery, volume 33, issue 6, 2011, Pages 467~477
Purpose: The objective of this study was to examine the affected period and the amount of bone formation during osteogenesis of intramembranous bone using low-intensity pulsed ultrasound (LPUS)
. Methods: Xeno-bone (Bio-oss) and autogenous bone were grafted bilaterally into mini-pig mandibles. The left mandible served as the control and the other mandible was treated with 3 MHz, 160 mW (output, 0.8 mW) ultrasound stimulation for 7 days 15 minutes per day. The mini-pigs were sacrificed at 1, 2, 4, and 8 weeks, and micro computed tomography (
), a microscopic examination, and a statistical analysis were performed on the specimens. Results: Based on a computerized image analysis of the
scans, the experimental group had an average 150% more new bone formation than that in the control group. The effect of LPUS continued during the post operative 2 weeks. The histomorphological microscopic examination showed similar results. Conclusion: Our results suggest the LPUS had an effect on early intramembranous bone formation in vivo.

Purpose: Free flap reconstruction is performed on defects including benign and malignant tumors as well as trauma in the department of oral and maxillofacial surgery, but there are few reports of free flap reconstruction cases for oral cancer in patients in Korea. Methods: This study was designed to retrospectively analyze surgical outcomes and complications of 164 free-flap reconstructions performed at the Oral Oncology Clinic, National Cancer Center, during 2002~2011. A total of 164 free flaps were performed for reconstruction of oral and maxillofacial defects which were caused by oral cancer and osteoradionecrosis in 155 patients. Results: The present study had 162 successful cases and 2 failed cases for a total of 164 cases. The study had a success rate of 98.8% for free-flap reconstructions. Flap donor sites included radial forearm free flap (n=93), fibula osteocutaneous free flap (n=25), anterolateral thigh flap (n=18), latissimus dorsi myocutaneous flap (n=16) and other locations (n=12). Postoperative medical complications were generally pneumonia and delirium. Postoperative local complications occurred including partial flap necrosis, delayed wound healing of the donor site, infection of the recipient site and salivary fistula. The incidence of postoperative complications and patient-related characteristics including age, sex, smoking, history of radiotherapy, hypertension (HTN) and diabetes Mellitus (DM) were retrospectively analyzed. Patient age (
=0.003) and DM (
=0.000) and HTN (
=0.021) were significant risk factors for complications overall. Conclusion: The present study had no mortality and confirms that free-flap reconstructions are extremely reliable in achieving successful results.

Purpose: Craniofacial structure form results from the adaptation to morphologic and functional changes in their neighboring structures for a mutual balance. The purpose of this study is classification of maxillomandibular complex growth pattern follow by cranial base growth pattern. And this study is identifying the correlation between maxilla-mandibular complex growth pattern and orthodontic criteria. Methods: 142 Class III malocclusion patients had orthognathic surgery at Wonkwang University Dental Hospital during April 2004 to October 2010. Patients were divided into 4 groups and the correlation between cranial base and maxillomandibular growth patterns were evaluated. Results: There was a correlation between cranial base and maxillomandibular growth patterns. Positive relationships were found between the occlusal plane, Incisor mandibular plane angle, mandibular plane, positioning of pogonion and the saddle angle, indicating maxillary growth patterns. Negative relationships were found between SNA, SNB, maxillary incisor angle and saddle angle. Positive relationships were found between the ratio of the anterior and posterior cranium, positioning of pogonion and the percentage of cranial depth indicating mandibular growth patterns. Negative relationships were found between the occlusal plane, maxillary incisor angle, mandibular plane, mandibular angle and cranial depth. Conclusion: Cranial base and maxillofacial growth patterns were correlated and the classification should be adjusted before orthognathic surgery.

Maxillofacial Plastic and Reconstructive Surgery, volume 33, issue 6, 2011, Pages 490~496
Purpose: Dr. Marquardt made the facial 'phi' mask using golden ratio. Most class III patients have bulky faces and want a smaller face. Using a facial golden mask, this study estimated and compared frontal photographs before and after operation for soft tissue measurement. The golden mask can be considered as a reference tool for facial esthetic analyses especially in lower face. Methods: Forty patients who had undergone orthognathic surgery at Samsung Medical Center from January 2006 to December 2009 were included in this study. These patients had Class III malocclusion. Lateral cephalometric radiographs, frontal clinical photos of pre-op and 8~12 month later post-op, and the facial 'phi' mask using golden ratio, were used for analysis. Reduction of the lower face area, occlusal plane changes, amounts of mandible setback and amounts of maxilla posterior impaction were estimated. Results: Lower facial reduction ratio and mandibular setback amounts were significantly different between 1-jaw and 2-jaw groups. Average postoperative changes in the area of lower face between bilateral sagittal split ramus osteotomy (BSSRO) and BSSRO combined maxilla posterior impaction were compared by using an independent simple t-test and
value was 0.016. Therefore, the lower facial reduction ratio and mandibular setback amount were significantly different in maxilla posterior impaction. Conclusion: The two-jaw surgery group showed more reduction of the lower facial area than the 1-jaw surgery group. The amount of lower facial reduction was more related with the amount of mandibular setback. There was no significant relation in lower facial reduction with amount of maxilla posterior impaction, pre-op occlusal plane, post-op occlusal plane and the mandibular angle. A relationship between the change in the lower facial area and the amount of maxilla posterior impaction or the change of mandibular angle occlusal plane at pre-op could not be found because of the difference in the amount of setback between two groups.

Purpose: Patients who had a subcondylar fracture with a displaced or deviated condylar segment were treated with a retromandibular approach (RMA) or an endoscope-assisted transoral approach (EATA) in our department of oral and maxillofacial surgery. The clinical results of the approaches were compared. A comparative study of specific approaches for subcondylar fractures has not been published before in Korea. Methods: Twenty-one patients with subcondylar fractures of the mandible were included. Ten patients were treated with the retromandibular approach and 11 were treated with an endoscope-assisted transoral approach. We examined patient age, gender, fracture sites, classifications, period of maxillomandibular fixation, facial nerve (FN) or greater auricular nerve (GAN) injuries, maximal mouth opening, deflection, occlusal changes, number of plates, follow-up period, and other complications. Preoperative computed tomography and pre-operative, post-operative, and follow-up panoramic views were taken of each patient. Results: Mean maximal mouth openings were similar between the two approaches. FN and GAN injuries were more frequent in the RMA group but the deflective rate with mouth opening was higher in the EATA than that in RMA group. Two cases of post-operative infection occurred in the EATA group, and occlusal changes were observed in one case for both approaches. Conclusion: The RMA offers more direct access and visualization of the surgical field but it can cause scars and retractive injuries of the FN and GAN. But, EATA did not result in consequent nerve injuries or scars postoperatively, but unfavorable fractures such as
condyles were more difficult to reduce endoscopically. Except cases of an expected difficult reduction, the treatment of choice for a displaced subcondylar fracture may be an EATA.

Maxillofacial Plastic and Reconstructive Surgery, volume 33, issue 6, 2011, Pages 505~511
Purpose: This study evaluated correlation and risk factors between position of the mandibular third molars and mandibular angle fractures using clinical and radiographic findings. Methods: Medical records and panoramic radiographs of 188 patients with mandibular fractures were retrospectively reviewed. The presence and position of the third molars were assessed for each patient and were related to the occurrence of mandibular angle fractures. Results: The incidence of mandibular angle fracture was found to be greater when a lower third molar was present, particularly at the occlusal plane positioned on the
molar occlusal surface (by Archer system) and the third molar is impacted in mandibular ramus (by Pell & Gregory system). Of the 192 sites with a lower third molar, 32 (16%) had an angle fracture. Of the 184 site without lower third molars, 16 (8%) had an angle fracture. Conclusion: This study confirmed an increased risk of angle fractures in the presence of a lower third molar as well as variable risk for angle fracture, depending on positioning of the third molar.

Purpose: Although obesity is a well-established risk factor for many cancers, the effect of body mass index (BMI) on oral cancer risk remains controversial. We therefore investigated the effect of BMI on oral cancer risk in a case-control study in Korea. Methods: Overall, 364 patients with oral cancer and 439 community controls were enrolled. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using logistic regression models, adjusted for age, smoking status and alcohol consumption. Results: We found no overall significant evidence of an association between oral cancer risk and BMI in either gender. However, when the relationship between BMI and oral cancer risk was examined according to female age groups (<50 and
50 years), there was a significant association between oral cancer risk and high BMI in female subjects younger than 50 years of age (OR=3.92, 95% CI 1.03~14.9,
for trend=0.04), but not in older (
50 years) female subjects (OR=1.11, 95% CI 0.55~2.24,
for trend=0.76). There was no significant relationship between BMI and oral cancer risk in any of the male age subgroups. Conclusion: Our study provides the first epidemiological evidence supporting an association between obesity and an increased risk of oral cancer.
Trapdoor Approach for Removal of the Pleomorphic Adenoma in the Palate: Case Report
Lee, Eun-Young ; Kim, Kyoung-Won ;
Maxillofacial Plastic and Reconstructive Surgery, volume 33, issue 6, 2011, Pages 520~524
A 27-year-old female presented to our hospital with a slow growing, hard and soft palate mass on the right that had been present for the several months. Physical examination showed a 2 cm, firm, well-circumscribed, painless mass on the right side of the palate. PNS computer tomographic imaging showed a
cm well-defined cystic mass on the right side of both the hard and soft palate without any underlying bone change. The lesion was completely excised under general anesthesia. In order to preserve the palatal mucosa, trapdoor approach for removal of the pleomorphic adenoma was done. This technique provided more comfortable healing of the operative site. Three years after surgery, there was no evidence of recurrence. If pleomorphic adenoma without bony and mucosal destruction exists, we suggest consideration of the trapdoor approach to protect the palatal mucosa. In view of the potential for tumour recurrence, long-term follow-up and careful examination are necessary.

A deep circumflex iliac artery (DCIA) flap is usually used for reconstruction in oral and maxillo-facial surgery department since introduced by O'Brien in 1975. Various flap designs are possible for osteomusculocutaneous, musculocutaneous, musculosseous and vascularized bone types. Iliac crest shape is similar to contour of mandible. Moreover, though a fibular flap has only 15~20 mm of cutting plane width, a DCIA flap contains much more bone amount, making this a similar reconstruction compare with normal mandible. A 68 year-old male with squamous cell carcinoma on the anterior floor of the mouth had an impression with T2N0Mx and the treatment procedure was DCIA reconstruction after wide resection and marginal mandibulectomy, with both supraomohyoid neck dissection. We present an experience of DCIA flap for reconstruction with a literature review.

Pathologic fractures of the mandible can occur for many reasons including osteoradionecrosis, osteomyelitis, malignancy and cyst. Pathologic fractures are difficult to treat because management is needed not only for the fractures of the mandible but also the underlying disease the is weakening the bone. Additionally, the diseased mandible in the pathologic fracture frequently has abnormal bone healing capacity. We experienced three cases of pathologic fractures of the mandible resulting from cyst, malignancy and osteomyelitis. The treatment of these cases was complicated and time-consuming. Therefore, we present our three cases and discuss the management of pathologic fractures of the mandible.

Epidermoid cyst is a cystic form of teratoma and believed to be derived from trapped embryonic cells along the lines of embryonic closure. A 28-year-old woman presented with a painless swelling over the left mandibular area. On panoramic view, the mandible revealed a
multilocular radiolucent lesion of the left mandibular body and a computed tomography scan showed expansion of both the buccal and lingual plates in the same area. Microscopy found stratified squamous epithelium of the cystic wall and cystic contents of keratinized material. The histological diagnosis wasan epidermoid cyst. The most common location of epidermoid cyst at the head and neck is in the orbit (47%), followed by the mouth floor (23%) and the cervical area (9~24%), but in the jaw bone, it is considered very infrequent. We report the uncommon epidermoid cyst in the mandibular body that had a good healing outcome after treatment with a conservative marsupialization during the 40 months follow-up.

Maxillofacial Plastic and Reconstructive Surgery, volume 33, issue 6, 2011, Pages 540~548
Proteus syndrome is a congenital hamartomatous malformation that is characterized by a wide range of deformities, including craniofacial deformities. Proteus syndrome features partial gigantism and asymmetry of the limbs, plantar hyperplasia, hemangiomas, lipomas, lymphangiomas, varicosities, verrucous epidermal nevi, macrocephaly, cranial hyperostosis, and long bone overgrowth. We diagnosed Proteus syndrome in a male patient who visited our hospital with a chief complaint of limited mouth opening and report the case because we obtained a good healing outcome after treating the condition with a corrective osteotomy.
Anatomical Review of Latissimus Dorsi Free Flap for Oral Cavity and Facial Reconstruction
Kim, Soung-Min ; Jung, Young-Eun ; Eo, Mi-Young ; Kang, Ji-Young ; Seo, Mi-Hyun ; Kim, Hyun-Soo ; Myoung, Hoon ; Lee, Jong-Ho ;

The latissimus dorsi myocutaneous flap (LDMF) was initially described at the turn of the century by Tansini et al, and latissimus dorsi myocutaneous free flap (LDMFF) was also first described for the coverage of a chronically infected scalp by Maxwell et al. As a pedicled flap, LDMF has been often used for breast reconstruction and for soft tissue replacement near the shoulder and the lower reaches of the head and neck. LDMFF is a flat and broad soft tissue flap with large-caliber thoracodorsal vessels for microvascular anastomosis. A skin paddle of the LDMFF can be more than
cm, so very large defects in the oral cavity and outer facial region can be covered by this LDMFF. Other advantages include consistent vascular anatomy, acceptable donor site morbidity and the ability to perform simultaneous flap harvest with tumor resection. For a better understanding of LDMFF as a routine reconstructive procedure in large defects of the oral cavity and facial legion, anatomical findings must be learned and memorized by young doctors during the special curriculum periods for the Korean national board of oral and maxillofacial surgery. This review article discusses the anatomical basis of LDMFF with Korean language.
