Fibrous dysplasia is a nonneoplastic developmental disease of osseous tissue. It is a lesion of unknown etiology, uncertain pathogenesis, and diverse histopathology. In this series of 16 patients with fibrous dysplasia of the craniomaxillofacial bones, the disease was generally monostotic and most commonly maxillary in location. Two patients demonstrated typical symptoms of the McCune Albright syndrome. Marked deformity or functional disturbances were the major indications for treatment. Total excision of the involved bone was the most successful form of treatment but produced the greatest functional and cosmetic deficits and long-term postoperative complications. A conservative therapeutic approach with a modest reduction in the bulk of these lesions may be sufficient to relieve signs and symptoms effectively. Periodic follow-up is indicated to detect recurrences or malignant changes in the early stages.

In this current study, the clinical data and postoperative follow-up findings of 118 patients with a primary lower lip carcinoma who were treated between 1983 and 1999 in the Department of Plastic and Reconstructive Surgery are presented. Medical records were reviewed retrospectively and data were collected concerning age, gender, followup period, location of lesion on the lip, cervical metastasis at presentation, preoperative biopsy results, histological grade, initial treatment, reconstruction type, pathological outcome, local recurrence, regional lymph node metastasis, treatment of local recurrence and regional lymph node metastasis, and postoperative treatment. The prognostic value of clinical stages in relation with recurrence and mortality from disease was investigated. The overall rate of recurrence was calculated as being 39.8%, and the determinate survival rate was found to be 72.9% at 5-year follow-up. The data concerning the above-mentioned parameters, together with risk factors that might play a role in the development of lip cancer, are discussed in light of the current literature.

All suspected congenital abnormalities of the nose require further evaluation. The nasal dermoid sinus cyst (NDSC) is one of the many midline nasal masses that often pose diagnostic and treatment dilemmas for the plastic and reconstructive surgeon. NDSCs are distinct from other facial dermoids in their potential for involving deeper contiguous structures, and intracranial extension. Accurate diagnosis and effective treatment are essential to avoid craniofacial skeletal deformation, cyst rupture, and infection that could cause cutaneous, ocular, or intracranial complications. A comprehensive discussion of the embryogenesis, pathogenesis, diagnosis, and surgical management of the NDSC is presented to delineate the role of open rhinoplasty in optimizing the management of this congenital nasal deformity.

A 72-year-old-female presented with a giant schwannoma on the medial side of her right upper arm. Ultrasonographic and magnetic resonance imaging examinations showed that it was almost a totally cystic lesion. It was initially misdiagnosed as a hydatid cyst. After excision of the tumor, histopathological examination revealed that it was a schwannoma composed of two types of regions known as Antoni A and B regions. The tumor was 15 x 8 x 7 cm in size. There were no neurological sequelae after the operation. This is probably the biggest schwannoma of the upper extremity reported.

Bone grafting plays an important role in the dental rehabilitation of patients with alveolar cleft. During the period between 1993 and 2001, 12 patients with alveolar clefts have been treated in our clinic. Cancellous iliac bone grafts were used in all 12 patients. Seven patients had left and five patients had right complete unilateral cleft lip and complete cleft palate operations. All patients had palatal fistulas. The ages were between 4 and 18 years (mean age, 10.5 y). Seven of them were female (58.4%) and 5 were male (41.6%). All the cancellous grafts survived. Enough filling and the closure of the fistulas were achieved except one patient who had wound dehiscence and partial graft loss. The patients experienced a limp for 2 days (mean time) because of the donor site. This surgical procedure achieves successful results if it is used with the proper indication in suitable cases.

Four cases of facial cleft that fit the anatomic description of the rare Tessier no. 2 cleft, with two patients having the no. 12 cleft extending to the cranium as no. 2 clefts, are presented. In all patients, clinical expressions of the anomaly were different. Thus, diverse surgical procedures were used in all cases. These cases and review of the literature help to define the soft-tissue and bony course of these clefts, and also emphasize the role of three-dimensional computed tomography scan imaging to show the bony cleft route. The diagnosis and treatment plan of the no. 2 cleft as well as its cranial counterpart are discussed in this report.

A case of facial cleft that fits the anatomic description of the rare bilateral Tessier no. 5 cleft accompanied by unilateral no. 1 and no. 6 clefts is presented, and brings the total number of reported cases to 21. This case and a review of the literature help to define the soft-tissue and bony course of these clefts, and also emphasize the role of three-dimensional computed tomography to show the bony cleft route. The diagnosis and treatment plan of the no. 5 cleft as well as other rare clefts such as no. 1 and no. 6 clefts are discussed.
