Journal of the Korean Association of Oral and Maxillofacial Surgeons.2005;31(1):89-93.

Intraosseous neurilemmoma(Schwannoma) is an extremely rare benign neoplasm. The site most commonly involved is the mandible. This occurrence is understandable because of the length of the inferior alveolar canal through the mandible. No other bone contains a canal that transmits a neurovascular bundle of such size and length. We report on a peripheral and central neurilemmoma along pathway of inferior alveolar nerve of the lower lip and mandible in a 28-year old man. A panoramic radiograph of the mandible showed a well-defined bilocular lesion with a thin uniform sclerotic margin located in the ramus and body of the mandible. The CT scan confirmed a well-defined lesion with thinning of the cortex of the body of the left side of the mandible. Histologically, the lesion was a cellular neoplasm with distinct palisading and numerous Verocay bodies. Complete excision was achieved by removing the tumor with the inferior alveolar nerve.

Journal of the Korean Association of Oral and Maxillofacial Surgeons.2005;31(1):82-88.

Treatment methods of mandibular condylar fracture were conservative and surgical method. Surgical method of mandibular high condylar fracture was very difficult because approach and internal fixation of small size fracture fragment were difficult. So there is a tendency to select conservative method over surgical method for guiding a stable occlusion and avoiding TMJ disorder and growth disturbance, minimizing pain and deviation during function. But, in case of mandibular high condylar fracture patient who has no biting teeth on posterior teeth area, guiding a stable occlusion and conservative functional treatment were very difficult. In this case, patient was 62years old male. He had fracture of mandibular symphysis, right mandibular body, left mandibular high condyle. We treated the patient for mandibular symphysis and right mandibular body fracture area with surgical method. But left mandibular high condylar fracture area was difficult to treat with surgical method. So we selected a conservative functional method on left mandibular high condylar fracture area. We intended recovery of vertical dimension and stable occlusion with implantation of immediate provisional implant on maxillar and mandibular posterior teeth area, and temporary crown. And then patient did mandibular functional movement and his mandibular function was recoverd.

Hyeon Min KIM ; Jong Cheol JEONG ; Min Seok SONG ; Jung Hui JANG ; Nam Hun KIM

Journal of the Korean Association of Oral and Maxillofacial Surgeons.2005;31(1):74-81.

In 1974, Casson et. al. reported midfacial degloving approach to repair the midfacial bone fracture. After then, this approach has been used frequently to treat the lesions on nasal cavity, nasopharynx, facial plastic surgery and midfacial trauma. Midfacial degloving approach consists of 1) bilateral sublabial incision 2) complete transfixion incision/ septocolumellar incision 3) bilateral intercartilaginous incision 4) bilateral pyriform aperature incision. This approach provides proper access for midfacial bone structure without facial scar but has post-operative complications such as transient epistaxis, infraorbital nerve paresthesia and nasal crust. We treated three patients using midfacial degloving approach to correct traumatic deformity in midface area. In two patients, rhinoplasty with autogenous rib graft was done simultaneously. So we report these cases with review of literatures.

Min Young SHIN ; Hyuk Kee LEE ; Je Won CHOI ; Sung Soo SHIN ; Yang Ho PARK ; Jun Woo PARK

Journal of the Korean Association of Oral and Maxillofacial Surgeons.2005;31(1):70-73.

An Ameloblastoma is one of the most common odontogenic tumors. The treatment of ameloblastoma has been controversial because of this disease entity as a slow-growing, locally invasive tumor with high rate of recurrence. Recurrence rate of ameloblastoma are reported 15% to 25% after radical treatment and 75% to 90% after conservative treatment. On the other hand, Robinson and Gardner reported that the recurrence rate after conservative treatment of unicystic ameloblastoma was lower than those of multicystic or solid lesion. In this report, what we want to show is to review the articles to find out pros and cons of conservative treatment of ameloblastoma. In addition we would like to discuss which requies conservative treatment or radical treatment are more acceptable through our case report.

Journal of the Korean Association of Oral and Maxillofacial Surgeons.2005;31(1):60-69.

Orthopedic rapid maxillary expansion(RME) has been a common treatment modality used to widen narrow maxillae in young children. However, since more skeletally matured adolescents or adults has closed midpalatal suture, the result of RME was undesirable because of dental tipping with little or no basal skeletal movement and resulted to many other complications. After such treatment, complications often occurred such as alveolar bending, compression of periodontal ligament, extrusion, buccal tipping, and severe relapse. Thus, surgically assisted rapid maxillary expansion(SA-RME) is required, especially for patients over 14 years old, to skeletally release maxillary expansion. We used two methods of maxillary expansion surgery. Surgically assisted rapid maxillary expansion(SA-RME) and surgically assisted posterior segmental expansion(SA-PSE) were used for narrow maxilla. The study was divided into two groups(SA-RME group and SA-PSE group). SA-RME group was consisted of 2 males and 4 females, and the ages of materials ranged from 15 years to 25 years with a mean of 20.2 years. SA-PSE group was consisted of 1 male and 5 females, and the ages ranged from 13 years to 23 years with a mean of 18.7 years. Dental study models were fabricated before starting the expansion and immediately after the expansion was completed. It was fabricated again 1 month later, 3 months later when the expansion device was removed, and 6 months later after the expansion was completed. A repeated measures analysis of variance(ANOVA) test was applied to assess changes between each groups over time. The amount of expansion and the amount of tipping movement each in both groups were compared by using paired t-test and it was also compared between each subjects within the group by using independent t-test. Both SA-RME and SA-PSE group showed stable results, but SA-PSE group showed statical significance in tipping movement of second premolar. We compared 6 patients who recieved SA-RME with 6 patients who received SA-PSE, and appraised the clinical usefulness.

Journal of the Korean Association of Oral and Maxillofacial Surgeons.2005;31(1):55-59.

PURPOSE: This study is to predict the changes of the distal segment by investing the resorption of the excessive distal segment regarding the amount of setback after BSSRO. MATERIAL AND METHODS: 20 patients with Mandible prognathism treated by Obwegeser-Dal Pont method during the years 2000 to 2002 were selected for this study. Group A consisted of 5 males and 5 females with a setback amount of 10mm and above(Mean 10.80mm+/-1.03, n=20) and Group B consisted of 2 males and 8 females with a setback amount of below 10mm.(Mean 6.10mm+/-1.10, n=20) Panorama X-ray was taken at day 1, 1month, 3months, 6months, and 12months after the surgery. Resorption areas of excessive distal segment were measured on these panorama X-rays and compared. RESULTS: There was bone resorption in both groups. Group A showed more bone resorption than Group B. Group B showed slightly higher resorption rate than Group A. However, there was no statistically significant difference between the resorption rates of Group A and Group B. (P>0.05) CONCLUSION: More bone resorption occurred with a larger amount of setback and about one third of the excessive distal segment underwent resorption, irrespective of the amount of setback.

Journal of the Korean Association of Oral and Maxillofacial Surgeons.2005;31(1):46-54.

PURPOSE: This study was performed in order to compare the osseointegration of 4 different surfaced implants in the dog's tibia which has thick dense cortical bone and loose marrow space. MATERIALS AND METHODS: Four mongrel dogs and four different surface types of implants, smooth surfaced AVANA implants, RBM surfaced AVANA implants, HA-coated Steri-Oss implants and SLA Bicon implants, were used in this study. The animals were divided into 4 groups on the basis of implant surface characteristics: Control group, RBM group, HA group, and SLA group. Three implants of each group were installed into the metaphysis of tibia of adult dogs. The animals were sacrificed at 8 weeks after implantation. The undecalcified specimens were prepared for histological examination and histomorphometric analysis of implant-bone contact ratios. RESULTS: Radiographically and histologically good osseointegration of implant was observed in the dense cortical bone, but poor osseointegration was observed in the marrow space. Histologically more bone apposition to implant surface was found in rough surfaced groups than the smooth surfaced, Control group. In histomorphometric findings of cortical bone the average bone-implant contact ratios of HA group (95.4%, p<0.01), RBM group (87.1%, p<0.05), and SLA group (86.0%, p<0.05) were significantly higher than that of Control group (75.9%). In marrow space the average bone-implant contact ratios of HA group (76.1%, p<0.01) and SLA group (45.4%, p<0.05) were significantly higher than that of Control group (29.6%). The ratio of RBM group was higher than that of Control group but there was no significantly difference between RBM group and Control group. CONCLUSION: These results suggest that the rough surfaced implants can obtain the better osseointegration than the smooth surfaced implant in the cortical and marrow space and that HA-coated implants can obtain the best osseointegration in the marrow space among them.

Injury of submandibular gland and lingual nerve as complication third molar tooth extraction in mandible : a case report.

Jae Sung LIM ; Hyun Joong YOON ; Sang Hwa LEE

Journal of the Korean Association of Oral and Maxillofacial Surgeons.2011;37(2):137-141. doi:10.5125/jkaoms.2011.37.2.137

The extraction of an impacted third molar tooth is associated with many complications during the procedure and postoperative care. These complications include bleeding, swelling, pain, infection, as well as root fracture, proximal tooth injury, alveolar bone fracture, lingual nerve and inferior alveolar nerve injury etc. With the exception of a fractured root dislocation in the submandibular space, no direct submandibular gland injury related to extraction surgery has been reported until now. A 40 year old man visited the department of oromaxillofacial surgery at Yeouido St. Mary's Hospital for an extraction of the right mandible third molar. A partial third molar impaction was diagnosed by a clinical and radiographic examination. A surgical tooth extraction was practiced including buccal cortical bone osteotomy. During socket curettage, an encapsulated cyst-like lesion and a verified 3x3 cm neoplasm in the apically lingual direction were found during process of dissection. A biopsy confirmed that the neoplasm involved the submandibular gland and nerve trunk. This unusual anatomical organ injury during the surgical tooth extraction procedure is reported as a new complication during impacted third molar extraction.

Treatment of large sized cystic lesion of the jaws with specific appliance for decompression: cases report.

Chang Su JANG ; Ju Won KIM ; Seung Bin YANG ; Jin Hyuk YIM ; Jwa Young KIM ; Byoung Eun YANG

Journal of the Korean Association of Oral and Maxillofacial Surgeons.2011;37(2):133-136. doi:10.5125/jkaoms.2011.37.2.133

Cystic lesions on the jaws with expansion can invade the adjacent anatomical structure, infiltrate and expand the jaws, cause facial deformity, etc. There is great potential for pathologic fractures after cyst enucleation, and damage to the major structures like the nerve, artery. For these reasons, marsupialization and decompression are commonly used to reduce the cystic size. In 1947, Thomas first mentioned decompression that reduces the osmotic pressure in a cyst by making a hole in the cyst and insert a drain. In our cases, a large sized cystic lesion was treated with a specific device made from an orthodontic band and spinal needle. This device is easy and effective for applications and self irrigation.
