Highlights Osteoid osteoma is a benign bone neoplasm, with significant nocturnal pain that responds to NSAIDs. A case of an intra-articular osteoid osteoma involving the articular eminence and glenoid fossa of TMJ in a 46-years-old female is reported. CT scan imaging is helpful in displaying the typical radiographic features and localization of the lesion.

Autogenous bone graft is the gold standard for maxillofacial reconstruction. Although there are many donor sites, the ilium is favored. Open iliac bone harvesting techniques can result in significant complications, which are to be reduced; a minimally invasive technique using trephine burs was used. The aim of the study was to evaluate the intra- and postoperative complications, the size of bone harvested, and the time of the procedure. Eighteen consecutive patients were conducted. The trephine bur makes holes of 10 mm diameter in the iliac crest from which a bone graft can be harvested. No major long-term morbidity was found; all patients were discharged on the first postoperative day. The trephine technique is generally a safe procedure, can provide enough corticocancellous bone for osseous defects in maxillofacial region up to 10 cc. In addition to that, the technique is easy to learn and allows early discharge of patients from the hospital.

Orofacial infections are considered as one of most common infections and need rapid and adequate treatment as they affect a very delicate region and are associated with serious life-threatening complications. Orofacial infections can be either odontogenic that is with an origin in teeth and associated structures or non-odontogenic, not associated with teeth, can affect facial spaces and spread from one space to another, so a good knowledge about diagnosis and treating these infections is of utmost importance, and can include both non-surgical and surgical treatment. The aim of our study was to determine the most common cause of orofacial infections, the most common bacterial microorganisms and their antibiotic susceptibility. Materials and Methods: A descriptive study was undertaken in the Department of Oral and Maxillofacial Surgery, Al-Shaheed Ghazi Al-Hariry Hospital, Baghdad, Iraq from 1 st January to 30 th September 2015. This study included 45 patients with different forms of orofacial infections; data regarding age, gender, underlying cause, facial space involvement, presenting signs were collected through history, clinical examination and radiographs, incision and drainage with swab sample for culture and sensitivity test was performed. Results: Patients with orofacial infections showed a female to male ratio of 1.25:1. The mean age was 32.8 years. Most of the patients were in their 4 th decade of life (27%). Most infections were odontogenic in origin (62%), the most common facial space involved was submandibular (65%), the most common isolated microorganism was Streptococcus pyogenes (59%), and most patients were treated using an extra-oral surgical approach (78%). Antibiotics to which bacterial isolated showed the most sensitivity were netilmicin, cefoperazone and rifampicin (91%). Pain and limitation of mouth opening gradually decreased in most of patients during the two weeks follow up period. Conclusion: Orofacial infections were more common in females, in the third and fourth decade of life, were odontogenic in origin, were mostly caused by Streptococcus pyogenes, and most isolates were susceptible to netilmicin, cefoperazone and rifampicin. Pain and trismus decreased over two weeks post-treatment.

Study Design: Facial contour deformities are a very challenging issue for aesthetic and reconstructive surgeons. Free dermal fat graft is a composite graft used for the reconstruction of soft tissue defects in the maxillofacial region. The free dermal fat graft is easily adapted and contoured intraoperatively and provides a soft, natural, and favorable appearance after augmentation of the soft tissue defects. Objective: To assess the use of free dermal fat graft for reconstruction of soft tissue defects in the maxillofacial region in regard to graft success, percentage of overcorrection, any associated complications, and cone beam computed tomography scan linear measurements for defect’s depth. Methods: This is a prospective study that included a patients were grafted with free dermal fat graft for correction of facial soft tissue defects from November 2017 to July 2019. All patients possess a depression defect and facial asymmetry due to congenital facial deformities, post-traumatic deformities, and post-ablative surgical deformities. Results: Eleven patients (8 males and 3 females) with a mean age of 33.7 years were enrolled in this study. Five regions in the maxillofacial area were grafted in 11 patients. The mean of the postoperative follow-up was 6 months. The percentage of graft overcorrection was 15%. The mean for graft survival was 94.4% with no serious complications reported. Conclusions: The autologous FDFG is a versatile and less invasive method in the reconstruction of facial soft tissue defects with a very good survival rate.
