We performed costochondral grafting in mmandibular reconstruction including condyle replacement in 5 patients which have 4 cases of ameloblastoma, 1 case of resorption of left condyle due to osteomyelitis. We harvested the 6 th costochondral cartilage of unaffected side. No specific complications were appeared with unexpected fracture of costochondral junction and infection of operation site, These patients show 30-45mm at month opening, near normal of affected side, near normal or normal of unaffected side at lateral excursion. Postoperative coureses was uneventful with improved cosmetic and functional results. Our report is indicated that the costochondral graft is satisfactory to reconstruct mandibular defect including condyle replacement, especially in growing patients.

Calcifying odontogenic cyst(COC) is comparatively rare in occurrence. COC represents about 1% of jaw cysts, and although it may occur in soft tissue, it is most commonly found within bone. Both the intraosseous and extraosseous forms occur with about equal frequency in the maxilla and mandible, mainly in the incisor and canine areas The most notable features of this pathologic entity are histopathological and include a cyst lining demonstrating characteristic "ghost" epithelial cells with a propensity to calcify and the occasional association of this finding with certain odontogenic tumors including the odontoma and the ameloblastoma. In this case, COC was associated with anterior wall of the maxillary sinus which appeared in the anterior maxilla of 64-year-old woman, was reported. We report that the clinical experience of COC with review of literatures.

The authors investigated the 17 patients with the condylar fractures of the mandible who were admitted in Dept. of Oral and Maxillofacial Surgery, Chosun University, Dental hospital from 1990 to 1993 and could be taken follow-up above 6 months. Helkimo's clinical dysfunction index and mandibular mobility index were applied to the evaluation of the patients and the obtained results were as follows. 1. Mean maximal mouth opening was 38.4 mm in the conservative group, 41.3 mm in the surgical group and that showed no statistically significant difference.(P>0.05) 2. Clinical dysfunction index was higher in the surgical group than in the conservative group but .that showed no statistically difference.(P>0.05) 3. The extent of maximal mouth opening was increased gradually throughout the follow-up period. 4. Both groups didn't show severe clinically dysfunction.

Over the past few years, a large number of perforator flaps have been revised by several microsurgeons in the USA, France, Canada and Japan. A perforator flap is a flap of skin or subcutaneous tissue that is based on the dissection of a perforating vessel, which is a perforator. In short, a perforator is a vessel that has its origin in one of the axial vessels of the human body. By reducing any muscle harvesting and trauma to a minimum, perforator flaps aim to minimize donor site morbidity, and by avoiding the transfer of dennervated muscle, the long-term bulk of the free tissue transfer becomes more predictable. There are a finite number of potential perforator flaps in the body, which are based on the named source arteries. The most commonly used perforator flaps are deep inferior epigastric perforator, superior gluteal artery perforator, thoraco dorsal artery perforator, medial sural artery perforator, and anterolateral thigh perforator flap. For a better understanding of perforators as a routine reconstructive procedure in oral and maxillofacial surgery, the definition with nomenclature, classifications with special characteristics, and review points for their individual applications must be learned and memorized by the young doctors in the course regarding the special curriculum periods for the Korean national board of oral and maxillofacial surgery. Perforator flaps have been known to have many advantages, so this review article summarized their applications to the maxillofacial reconstruction in the Korean language.

We described three cases of immediate reimplantation of a frozen-thawed autogenous mandible composed of a mixture of iliac bone, marrow, and particulate hydroxyapatite in tumors of the mandible. Acceptable outcomes were obtained in three patients who underwent immediate autogenous mandibular graft reconstruction. The conditions leading to successful outcome of the procedure are also discussed. Reimplantation of frozen autogenous lesioned mandible was performed in three patients with mandibular tumors. Two reimplanted grafts survived without complications following surgery. One case had postoperative infection that resolved with appropriate antibiotic treatment. There were no recurrences of the primary lesions. Satisfactory facial contour after surgery was achieved. These results are most promising, and we believe that, with further refinement, this technique will offer a new and acceptable modality for facial reconstruction in patients with cancer.

Background: Hemangioma and vascular malformation are benign vascular lesions that often occur in cephalic and cervical region. Currently, surgical resection, laser therapy, angiographic embolization, use of steroids, and sclerotherapy are used as treatments. Case presentation: This study reports three cases of benign vascular lesions that are remarkably treated by sodium tetradecyl sulfate (STS) injection, of which occurred in oral cavity and around the mouth. Three percent of STS was diluted with 0.9 % of normal saline, and it was injected to the lesion site at least once. The result of treatment was evaluated based on clinical findings. Conclusion: Surgical treatment of hemangioma and vascular malformation occurred in oral cavity is not normally used because of esthetic issues and potential hemorrhage. On the other hand, sclerotherapy using STS is an effective therapy compare to surgical treatment. Despite the number of STS injection was different for each patient, all three patients had reached satisfactory level through the treatment with gradual diminution of lesions.

The postoperative maxillary cyst develops as a delayed complication after surgical intervention or Caldwell-Luc operation in the maxillary sinus and was also reported that it could occur after Le Fort I osteotomy. This is also called as surgical cliated cyst because of its lining epithelium is usually lined by a pseudo-stratfied ciliated columnar epithelium. This report represents a case of postoperative maxillary cyst which developed within the anterior of maxilla and in association with nasal mucosa 6 years after a Le Fort I osteotomy. In 1989, 26-year-old male complained of his mandibular prognathism and underwent orthogmathic surgery, Le Fort I osteotomy, bilateral sagittal split ramus osteotomy, partial glossectomy.

Postoperative infection following orthognatic surgery is rare. When postoperative infections occur, the initial treatment consists of incision and drainage of the affected area, culturing to identify bacterial stains and verify antibiotic sensitivity, and the institution of the appropriate antibiotic regimen. Some plates and screws may eventually require removal, the initial therapy should be attempted to retain the plates and screws until adequete healing has taken place. In orthoganthic surgery, intra-operative complications as a lesion of inferior alveolar nerve, fracture of osteomised segments, incomplete sectioning, malposition of segments, haemorrhage may occur. The surgeon should be familiar with possible complications to be caused and how to manage them. Prevention of postoperative infection following the orthognathic surgery consists of minimal periosteal reflection, aseptic management of operation field, proper surgical technique, rigid fixation, prophylactic antibiotics.

Angioedema is defined as self-limited, localized swelling. The swelling is asymmetric, non-pitting, and non-tender. Common locations of swelling include periorbital area, lips, tongue, extremities, and bowel wall. A 54-year-old woman visited our hospital with the clinical complaint of left maxillary swelling. Swelling of the left maxillary area was diffuse and temperature of the involved area was normal. No infectious source was found on panoramic radiography and cone-beam computed tomography. After considering the patient's medical history and assessing clinical examination, we suspected angioedema and administered corticosteroid only. In the oral and maxillofacial area, proper diagnosis and prompt treatment of angioedema is important because angioedema of the tongue or larynx may lead to airway obstruction or a life-threatening condition.
