Bone source for repair of craniofacial defects

Eight cases were included in this study, three cases were scheduled for frontal sinus obliteration, one case of cranioplasty for a congenital cranial defect and another four cases for facial augmentation and proper contouring. Frontal sinus obliteration was performed in three cases. Two cases suffered from large frontal sinus mucoceles encroaching on the orbit and perforating the roof of the orbit and the posterior table. The mucoceles were pathologic in nature causing chronic sinus disease. All skin incisions above the implantation sites were healed well without an evidence of excess scar formation or local tissue inflammation. There were no wound infections or hematomas and none of the implants became exposed or extruded. The surface area of the defects ranged from 4 to 15 cm2 with an average defect size of 10.2 cm2. The amount of HAC averaged 9.2 g with a range of 5-15 g. The largest amount of HAC was used to obliterate the frontal sinus. The difference in the amount was attributable to the depth of the osseous defect. There were no metabolic or surgical complications attributable to the use of HAC

Intraarticular meniscus surgery for internal derangement of the TMJ

A study was carried out on 23 patients who had undergone TMJ surgery because of disc displacement. Surgery was not considered until all the nonsurgical modalities were depleted. A review of the different surgical procedures utilized in the management of intrameniscal dysfunction was discussed. Clinical and radiographic assessments of 30 joints were undertaken. The clinical experience with meniscoplasty and meniscorrhaphy proved to be effective sound procedures when surgical treatment was suggested for patients with internal derangement of the TMJ. The role of surgery in TMJ dysfunction was studied. A total of 30 joints in the patients were operated upon, 24 of them were in 18 female patients and six were in five male patients. The most prevalent symptom preoperatively was TMJ pain, which presented 78%, 85% of them had mild TMJ pain and 10% reported moderate pain. The second most common symptom was joint noises, which presented 78%, 65% of them were painful clicks and 13% were non- painful
