Purpose: The purpose of this study is to induce artificial arthritis on rabbit TMJ by injecting collagenase. Materials and Methods: An experimental animal model of arthritis induced by surgical method or intraarticular injection of chemical agent like LDH, papain, ketorolac. Surgical method is complex and needs a long time in inducing arthritis. Intra-articular injection of chemical agent like LDH, papain, ketorolac is simple. But chemical agent like LDH, papain, ketololac needs multiple injections to induce arthritis and mechanism inducing arthritis was known. Collagenase destroys helical domain of type II collagen in extracellular matrix produced by chondrocyte and then induces arthritis. We injected collagenase (0.5, 1.0, 2.0 mg) into the temporomandibular joint of rabbit. In the control group saline was intra-articularly injected. The condylar cartilage, disk and synovia were histologically examined at 1, 2, 4, 6 weeks after the initiation of collagenase injections. Results: Four weeks after injection of 2.0 mg collagenase, we could see histologic change like arthritis. In other groups, we couldn't see arthritis-like change. Conclusion: In our study, we produce arthritis on temporomandibular joint of rabbit by using injection of collagenase in temporomandibular joint of rabbit. And this experimental osteoarthritis is a useful animal model.

Maxillofacial Plastic and Reconstructive Surgery, volume 32, issue 6, 2010, Pages 504~510
Purpose: This study was to examine the proliferation and function of the adipose tissue-derived endothelial cells according to different culture medium conditions. Materials and Methods: Adipose tissue-derived CD146 positive endothelial cells were cultured in according to different culture mediums (DMEM culture medium with or without osteogenic inductive agents and EBM-2 culture medium with or without osteogenic inductive agents). The proliferation and function of the adipose tissue-derived endothelial cells was examined in different culture medium conditions. Results: Adipose tissue-derived endothelial cells formed tube-like structures on Matrigel in EBM-2 culture medium with or without osteogenic inductive agents. However, the cells did not form tube-like structures on Matrigel in DMEM medium with or without osteogenic inductive agents. After 24 hours of culture, among the culture medium using EBM-2, the proliferation of the cells were promoted in EBM-2 medium without osteogenic inductive agents than in EBM-2 medium with osteogenic inductive agents. However, 72 hours of culture, the proliferation of the cells were promoted in EBM-2 medium with osteogenic inductive agents than in EBM-2 medium without osteogenic inductive agents. Conclusion: These results suggest that the proliferation and function of the adipose tissue-derived CD146 positive endothelial cells could be maintained in EBM-2 with osteogenic inductive agents.

Maxillofacial Plastic and Reconstructive Surgery, volume 32, issue 6, 2010, Pages 511~520
Purpose: This study was conducted in order to compare the efficacy of osseointegration of three different calcium metaphosphate (CMP) coated implants in the rabbit's femur. Materials and Methods: Twenty four rabbits and three different type of CMP coated implants and RBM implants were used in this study. The animals were divided into 4 groups on the basis of implant surface characteristics. Two implants were installed into the condyle of femur of each rabbits. The animals were sacrificed at 2 and 4 weeks after installation. The undecalcified specimens were prepared for histological, radiological examination and histomorphometric analysis of implant-bone contact ratios (BIC) and bone area ratio (BA). Results: Two implants were failed to osseointegrate and implant success rate was 95.2%. There were not any significant inflammatory response in all groups. Fluorescent image at 4 weeks shows that remodeling is slower in RBM group than CMP group. CMP III showed more active remodeling than CMP I, II. In histomorphologic analysis, BIC ratio at 2 weeks was lower than 4 weeks. Conclusion: The results suggest that the ratios of CMP coated implants were higher than that of RBM control group but there is no significantly difference between RBM group and CMP group. In conclusion, CMP coated implant had more clinical availability than RBM implants.

Maxillofacial Plastic and Reconstructive Surgery, volume 32, issue 6, 2010, Pages 521~528
Purpose: Anatomical reduction of the fractured condylar process is an important prerequisite for re-establishing function. The authors reported about effectiveness of transoral approach for mandibular subcondyle fracture using trochar device in cases that the fracture line is below the reference line, the perpendicular line of the longitudinal axis of condylar process passing the lowest point of sigmoid notch. As a serial study, we report the open reduction via preauricular approach for mandibular condyle fracture, in cases that the fracture line is above the reference line. Patients and Methods: Sixteen condylar fractures of 15 adult patients were divided two groups and treated by open reduction via preauricular approach (8 cases) or by closed reduction (8 cases). The degree of maximal mouth opening, occlusion, anatomical reduction, condylar resorption and complications were assessed and evaluated for the two groups. Results: The open reduction of condyle via preauricular approach leads to good results without permanent complications. Anatomical reduction of open reduction group and maximal mouth opening range of the closed reduction group is significantly better than the other group. No significant differences were found in the condylar resorption and the occlusion. Conclusion: The preauricular approach was useful to reduce and fix the condylar fragment, in cases that the fracture line is above the reference line.

Maxillofacial Plastic and Reconstructive Surgery, volume 32, issue 6, 2010, Pages 529~536
Purpose: The Purpose of this study is to show the total survival rate of implants with maxillary sinus grafting and the effects that reach the survival rate by classifying types of graft materials, implant type, operation method, residual bone height and evaluate graft material resorption rate after sinus grafting Patients and Methods: 61 dental implants placed with sinus bone grafting in 24 patients at Wonkwang University Sanbon Dental Hospital were installed simultaneously or after regular healing. Various bone grafts (autograft, xenograft, allograft, alloplast) and fourth implant type (GSII, Xive, Implantium, Novel biocare) were used. All implants were investigated clinically and radiographically, being with average 20 months follow-up period after installation. Results: 3 fixtures were lost, resulting in 95.1% cumulative survival rate of 61 osseointegrated dental implant. Survival rate according to bone material type, Implant type, operation method, residual bone height, have no statistically significant differencies. The mean preoperative residual alveolar bone height was 4.75 mm, average postoperative height of graft materials 10.8 mm, vertical bone resorption rate was 10% after 2 years. Resorption rate according to operation method was 7% (simultaneous) and 5% (delayed) after 1 year. Conclusion: It can be suggested that maxillary sinus grafting may have predictable result with various bone graft materials and implant type, residual bone height, operation method

Maxillofacial Plastic and Reconstructive Surgery, volume 32, issue 6, 2010, Pages 537~543
Purpose: The objective of this study is to evaluate the survival rate and influencing factors. Patients and Methods: We studied 104 patients who were diagnosed for squamous cell carcinoma of tongue and received curative treatment in oral oncology clinic of National Cancer Center from June 2001 to December 2009. Results: We found the following results. 1. The overall 5-year survival rate of tongue cancer was 67.0% and there was no significant statistical difference between male and female. 2. A lower survival rate was shown in patients under 40 years (42.2%) than over 40 years (75.5%)(P < 0.05). 3. 5-year survival rates of patients with tongue cancer classified by pTNM classification were 87.4% in early stage and 43.3% (P < 0.05). 4. A higher survival rate was seen in patients without cervical lymph node metastasis (82.0% > 44.1%)(P < 0.05). 5. A higher survival rate was seen in patients of tongue cancer with higher differenciation grade (P < 0.05). 6. It is well known that drinking and smoking have great influence on the survival rate of patients of squamous cell carcinoma of tongue. But these was no statistical significance. Conclusion: The overall 5-year survival rate of tongue cancer was 67.0% and it was mostly influenced by factors like age, pTNM stage, cervical lymph node metastasis, differentiation of cancer cell etc.

Purpose: The result of all malignant neoplasms including oral cancer is decided by long-term prognosis. However, until now, there are only a few reports about long-term prognosis of cancer secluded in the oral cavity. So, we investigated all patients that visited our clinic for oral squamous cell carcinoma (SCCa) for the last 10 years. From this survey, we hope to find important factors that influence prognosis of the disease. Patients and Methods: A retrospective study was performed for patients that visited the oral oncology clinic for oral cancers from Jan. 2001 to Feb. 2010. We selected the patients that were diagnosed with SCCa and received curative treatment. In these patients, we investigated basic epidemiology, smoking history, body mass index, recurrence rate, treatment methods, pathologic data and 5-yr survival rate. Results: There was a total of 185 patients (115 males, 70 females and mean age: 57.3 years) that visited the oral oncology clinic for oral SCCa. Areas of primary lesion were tongue (105 cases, 57%), lower gum (19 cases, 10%), floor of mouth (16 caess, 8%), retromolar trigone (12 cases, 6.5%), and buccal cheek (11 cases, 6%). Other involved areas were upper gum, palate, lip, and salivary glands-of 1 case each. The overall 5-year survival rate was 63.7%. The factors that influenced prognosis of the disease were stage of the disease, status of differentiation, recurrence, metastasis of cervical lymph node and age. Conclusion: The factors that influence prognosis of disease are stage of the disease, status of differentiation, recurrence, metastasis of cervical lymph node and age. To point out a current trend, the mean age of patients that developed oral cancer was lower than that of before. Secondly, the prevalence of oral cancer in non-smoker are on the rise. Thus, further studies on etiology and epidemiology should be done.

Purpose: In this study, we evaluated the relation between surgical methods and reccurrence rate by investigating clinical, radiological aspects and histopathological patterns of 26 patients who were diagnosed with amelobalstoma. Patients and Methods: In this study, we retrospectively investigated 26 patients who were diagnosed with ameloblastoma and treated at the Department of Oral and Maxillofacial Surgery of Chosun University Dental Hospital from January 2000 to December 2008. Results: The patients comprised 12 males (46.1%) and 14 females (53.9%), and their ages ranged from 10 to 69 years (average, 37.3 years). All cases presented a mandibular location, and in particular, 13 cases (50%) demonstrated an occurrence in the mandibular body. Clinically, 8 cases (30.8%) presented no symptoms, and the most prevalent chief complaint was swelling in 13 cases (50%). Radiographically, a unilocular type appeared in 14 cases (53.8%), and a multilocular type was observed in 10 cases (38.5%). Histopathologically, there were 8 follicular types (30.8%) and 7 plexiform types (26.9%). Conservative treatment was performed in 5 cases (19.2%), and radical treatment was performed in 21 cases (80.8%). The follow-up period ranged from 1 to 10 years. The total recurrence rate was 15.4%, and the mean duration of recurrence was 6.7 years. Three of the 5 cases (60%) that received conservative treatment demonstrated a recurrence, as compared to 1 of the 21 cases (4.8%) that underwent radical treatment. Conclusion: The radical treatment was more effective than the conservative treatment for recurrence prevention. We should consider a continuous follow-up check after operation.

Sinusitis has been reported as a complication of sinus lift surgery. Obstruction of the sinus outflow tract by mucosal edema and particulate graft material may result in sinusitis. Two main surgical procedures have been proposed for the treatment of associated infectious complications; inferior meatal antrostomy and functional endoscopic sinus surgery through transnasal approach. We performed superior lateral wall antrostomy through introral approach in patient suffering from the sinusitis after sinus floor augmentation and implant installation. This procedure permitted easier access to the maxillary sinus for treat sinusitis caused by sinus lifting.

Retrobulbar abscess is a rare, but severe complication of paranasal sinusitis. The clinical presentations are eyelid swelling, erythema, proptosis, conjunctival chemosis, restricted ocular movement, and decreased visual acuity. Diagnostic methods available for evaluating retrobulbar abscess include sinus X-ray, ultrasonography, computed tomography (CT), and bacterial culture. For the treatment of retrobulbar abscess, immediate surgical drainage and systemic antibiotic therapy are needed. Proper diagnosis and treatments are necessary for preventing visual loss, cavernous sinus thrombosis, subdural abscess, and other lifethreatening complications. A patient, a 30-year-old man, was admitted to our hospital because of progressive eyelid swelling, erythema, ptosis and decreased visual acuity on the right eye after endodontic treatment. The sinusitis occurred secondary to the infection from an upper molar tooth. The spread of the infection led to the orbit via ethmoidal sinus and posterior orbital wall. Immediate surgical intervention was performed and systemic antibiotics was administrated. The symptoms and signs are improved after treatments, so we present our case with a brief review of the literature.

Maxillofacial Plastic and Reconstructive Surgery, volume 32, issue 6, 2010, Pages 567~572
Intraoperative breakage of instruments can be occurred unexpectedly. To prevent damage of neighboring important anatomic structures and consequent complications, broken instruments should be removed as soon as possible. There have been several methods to remove broken instruments. One of them is the Carm fluoroscopy which is commonly used for locating metal foreign bodies. However, its application for removal of broken instruments in the oral and maxillofacial area is not common. In our experiences with the removal of two broken instruments in mandibular area, the newly developed dental mini C-arm was used to find broken instrument in soft tissue, because it gives real-time in situ information for the intraoperative location. We report two cases with broken instruments, a broken dental needle in the pterygomandibular space and a broken straight bur in the mandibular angle area. They were identified and could be removed safely using a dental mini C-arm.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular lesion that is characterized by proliferation of small to medium-sized vascular structures lined by histiocytoid or epithelioid endothelial cells and often accompanied by an inflammatory infiltrate comprising lymphocytes, plasma cells and eosinophils. A 34-year-old man without any generalized systemic conditions presented with a slowly enlarging painless swelling in the buccal area. An excisional biopsy was conducted and the diagnosis of Angiolymphoid hyperplasia with eosinophilia was confirmed. We report a case of angiolymphoid hyperplasia with eosinophilia of the buccal area in oral cavity and review the previously reported cases and literatures of angiolymphoid hyperplasia with eosinophilia.

Descending necrotizing mediastinitis (DNM) is a complication of odontogenic or oropharyngeal infections that can spread to the mediastinum. Such infections is serious, leading to sepsis and frequently to death. Even in this era of antibiotics, the mortality rate associated with DNM is approximately 40%. It is difficult to diagnose early because clinical and radiologic findings appear in the late stage of the infection. Delayed diagnosis is the principal reason for the high mortality in DNM. Therefore, descending necrotizing mediastinitis requires an early and aggressive surgical approach to reduce the high morbidity and mortality associated with this disease. We experienced a case of odontogenic infection followed by acute mediastinitis, so present now with the review of literatures.

Pilomatricoma or calcifying epithelioma is a benign tumor of hair follicle origin. Pilomatricoma presents a slowly enlarged and asymptomatic mass that located dermal or subdermal area. It showed mostly on face and upper limb and head and neck represents 50% of all case. And it developed almostly in the first 2 decade of life. Histologically, encapsulated mass composed of solid small basophilic cells and eosinophilic ghost cells. Surgical excision is the treatment choice and rarely recurs. The purpose of this article is to represent of pilomatricoma on subauricular region that treated with mass excision and local transpositional flap. Althrough the presurgical diagnosis of pilomatricoma may be difficult, clinicians must keep in mind the differential of head and neck masses that located subdermal layers.

Parotid deep lobe tumors usually has been treated by total parotidectomy. But there is functional and aesthetic side effects such as post parotidectomy depressions, variable aesthetic deformities, facial nerve injury and Frey's syndrome. Conservative limited deep parotidectomy may result in fewer side effect. Preservation of the superficial lobe for deep lobe tumors could decrease the incidence of complications without any problems in the treatment effect. Additionally, the parotid function preservation and cosmetic appearance after operation also satisfy both the patients and surgeons. We report a case of pleomorphic adenoma of the deep lobe which has been successfully treated by conservative deep parotidectomy.

The common local causes of active gingival bleeding are the vessel engorgement and erosion by severe inflammation and injury to hypervascularity lesion. Abnormal gingival bleeding is also associated with systemic bleeding disorders (liver disease, leukemia etc.). There are many conventional methods for gingival bleeding control, such as, direct pressure, packing, electrocoagulation, tight suture and application of hemostatic agents. If the continuous gingival bleeding is not stopped in spite of the all local application methods, the medical consultation should be obtained for systemic condition care and the major feeding arterial embolization. This is a case report of severe gingival bleeding and periodontitis control in a patient with liver cirrhosis and oral metastatic lesion of hepatocellular carcinoma. The bleeding lesion was placed in left buccal mucosa and gingiva of the left mandibular molars. The control methods were dental crown removal, primary endodontic drainage, gingival sulcus drainage and maxillary arterial embolization with medical consultation.

Subcutaneous emphysema and pneumomediastium is a relatively uncommon phenomenon. Most case of pneumomediastium are caused by iatrogenic injury on the cervical region and chest during tracheostomy. It is also well known that emphysema may occur secondary to dental treatment using high-speed air turbine handpiece, but there have been few cases of emphysema extended to involving the mediastinum. These complications are reported to occur mainly in patients after dental procedures, in particular during mandibular third molar extraction. Early recognition and conservative treatment of these problems is essential in preventing life-threatening complications such as airway obstruction, mediastinitis, pneumothorax and cardiac failure. As we report a case of 25-year-old woman with subcutaneous emphysema and pneumomediastium after mandibular third molar extraction using high-speed air turbine handpiece.

Oblique facial cleft is extremely rare. The frequency was reported 1/1300 cases of facial cleft. The cleft appears to be bilateral in approximately 20% and more often on the right when unilateral. Oblique facial cleft is nearly always associated with cleft lip and palate. Thus, the case that is unilateral on the left and not associated with cleft lip or palate is very rare. We experienced a case of 2 years 6 months old Philippine girl who had oblique facial cleft that is not associated with cleft lip or palate. The probable cause and treatment is discussed with a review of literatures.
