Malocclusion is a serious complication of open reduction surgery for facial fractures. It is often caused by the lack of adequate consideration for the occlusal relationship before the trauma and intermaxillary fixation during the operation. This is a case report of postoperative malocclusion that occurred in a patient with a midfacial complex fracture.

This is a case of bony ankylosis of right temporomandibular joint with mild facial asymmetry resulted from trauma, which bring about the right condylar fracture, and corrected by interpositional arthroplasty with temporal fascia flap and coronoidectomy. The postoperative results were functionally and esthetically good, but continued osbervation is necessary to evaluation of abnormal bony growth and reankylosis.

중앙안면골 골절 환자에서 비골 골절과 동반되는 경우가 많으며, 주로 안면골 골절의 정복시 비골도 동시에 정복하지만 여러 가지의 원인에 의하여 이차 비성형술을 시행하여야 하는 경우가 많다. 그러므로 중앙안면골 골절 환자의 초진시 비골 골절에 대한 정확한 진단과 정확한 비골 골절의 정복 그리고 일차 비골 골절의 정복후 이의 적절한 유지와 고정이 중요하지만 이차 비성형술의 가능성에 대비하여야 하며, 일차 비골 골절의 정복시 대칭적인 정복을 시행함으로서 비교적 간단하게 이차 비성형술을 시행할 수 있으리라 생각되었다. 또한 중앙안면골 골절환자에서는 비부의 연조직이나 연골의 이차변형에 의하여 이차 비성형술을 시행할수도 있으므로 일차 수술후 주의깊은 관찰이 요구된다. 이러한 이차 비성형술에는 자가이식재 및 Silicone이나 $Medpore^{(R)}$등이 이용될 수 있으며, 특히 인공이식재의 경우 공여부의 정확한 형성과 적절한 고정이 필수적이며 향후 이러한 인공이식재의 안정성에 대한 더 많은 연구가 이루어져야 할것으로 사료된다.

Objectives: Idiopathic bone cavity (IBC) is an uncommon intra-osseous cavity of unknown etiology. Clinical features of IBC are not well known and treatment modalities of IBC are controversial. The purpose of this study was to investigate the clinical characteristics of 27 IBC patients who underwent surgical exploration. Materials and Methods: A total of 27 consecutive patients who underwent surgery due to a jaw bone cavity from April 2006 to February 2016 were included in this study. Nine male and 18 female patients were enrolled. Patients were examined retrospectively regarding primary site, history of trauma, graft material, radiographic size of the lesion, presence of interdental scalloping, erosion of the inferior border of the mandible, complications, results of bone graft, and recurrence. Results: Female dominance was found. Maxillary lesion was found in one patient, and bilateral posterior mandibular lesions were found in two patients. The other patients showed a single mandibular lesion. The posterior mandible (24 cases) was the most common site of IBC, followed by the anterior mandible (5 cases). Two patients with anterior mandibular lesion reported history of trauma due to car accident, while the others denied any trauma history. Radiographic cystic cavity length over 30 mm was found in 10 patients. Seven patients showed erosion of the mandibular inferior border. The operations performed were surgical exploration, curettage, and bone or collagen graft. One bilateral IBC patient showed recurrence of the lesion during follow-up. Grafted bone was integrated into the native mandibular bone without infection. One patient reported necrosis of the mandibular incisor pulp after operation. Conclusion: Differential diagnosis of IBC is difficult, and IBC is often confused with periapical cyst. Surgical exploration and bone graft are recommended for treating IBC. Endodontic treatment of involved teeth should be evaluated before operation. Bone graft is recommended to reduce the healing period.

A ranula is a pseudocyst that originates from the sublingual gland after trauma. Acute cases of ranulas that progress rapidly and cause respiratory distress are rare. Holoprosencephaly is a complex brain malformation caused by incomplete cleavage of the prosencephalon. Children with holoprosencephaly may experience upper airway obstruction due to the associated dentoalveolar malformations and oromotor dysfunctions. We present the case of an eight-year-old female patient with holoprosencephaly and a plunging ranula that manifested as an acute course due to difficult airway management. She required gastrostomy for oromotor dysfunctions related to feeding and swallowing and difficulty managing oral secretions. The sublingual gland and ranula were removed under general anesthesia. Postoperatively, urgent reintubation and close monitoring in the intensive care unit were required due to upper airway obstruction. We successfully managed the patient with close cooperation of a pediatrician and an anesthetist, and no recurrence was observed at the one-year follow-up. A ranula can be caused by trauma to the floor of the mouth in association with lingually inclined mandibular teeth, a type of dentoalveolar compensation seen in maxillary hypoplasia associated with holoprosencephaly. Careful consideration is needed in such cases since airway management can be difficult due to postoperative swelling and oromotor dysfunctions.

Midfacial degloving approach는 중안면부에 대한 접근시 비교적 광범위한 수술시야의 확보가 가능하고, 술 후 중안모에 반흔을 남기지 않는 심미적 장점이 있다. 특히 중안면부의 광범 위한 골절과 비골 복합 골절을 동반한 중안면부 골절 수복에 이용되어 골절부에 대한 적절한 시야 확보로 정확한 관혈적 정복술이 가능하며 필요시에는 자가 늑골 등을 이용한 비 성형술이 가능하다는 장점이 있다. 이에 저자 등은 중안면부 복합골절의 치료시 midfacial degloving approach을 통해 중안면골의 관혈적 정복술 및 비 재건술을 시행한 증례에 대하여 문헌 고찰과 함께 보고하는 바이다.

Orbital roof and supraorbital ridge fractures are frequently associated with high energy concomitant craniofacial trauma. When a displacement of the orbital roof and supraorbital rim occurs, exploration, stabilization and reconstruction are warranted to limit the ocular complications. The management of fractures involving the frontal sinus must consider the possible need for obliteration or cranialization of the sinus. Many incisions have been described and used to approach these fractures, such as a coronal incision, eyebrow incision, and an incision through the laceration. We report 3 cases of orbital roof and supraorbital ridge fracture patients with a review of the relevant literature.

Distraction osteogenesis is a biologic process in which new bone is formed between bone fragments being separated by a tractional force. This technique has the advantage of initiating new bone growth without bone transplantation and promoting the growth of soft tissue. Mandibular distraction osteogenesis has shown to be effective to treat congenital or acquired mandibular hypoplasias. On the basis of positive results with implant-supported prostheses, the use of implants in the distracted site can significantly help stabilize the prosthesis. We obtained good result in the patient with mandibular deficiency due to trauma, who have been reconstructed with distraction osteogenesis and implant. We report our experiences with literature view.

A traumatic or amputation neuroma can develop as a result of nerve injury caused by hemorrhage, infection, ischemia, trauma, etc. A traumatic neuroma can be considered as the attempted regeneration of the amputated nerve rather than a true neoplasm. Occasionally, a traumatic neuroma will develop after oral or maxillofacial surgery. Here, we report a case of traumatic neuroma after mandibular angle reduction in a 24-year-old woman.

Osseous metaplasia is defined as the formation of lamellar bone inside soft tissue structures where bone normally does not exist. It results from the transformation of non-osseous connective tissue into mature bone. This condition is rare in the oral and maxillofacial region. We report a case of osseous metaplasia of the maxilla, a rare benign tumor in an uncommon region. A 60-year-old male patient visited our clinic complaining of foreign body sensation and asymptomatic swelling on the right palatal side. However, he did not experience pain and reported no local trauma that he could remember. Intra-oral examination revealed an exophytic lesion on the right palatal portion. On computed tomography, there was a round hard-tissue mass approximately 2 cm in diameter on the right palate area. The mass was biopsied and diagnosed as an osseous metaplasia. We review the clinical, radiographic, and histologic features and common causes of osseous metaplasia and report a rare case of osseous metaplasia of the palate.
