Bone quality assessment in patients with healing mandibular fracture sites: a computed tomography investigation.

The objective of this retrospective study was to assess the bone quality of healing mandibular fracture sites by measuring the Hounsfield units (HU) on computed tomographic (CT) images obtained presurgery and postsurgery in patients treated with rigid internal fixation (RIF). The HU values of healing fracture sites were compared to those of corresponding nonfractured (control) sites on the opposing side and cervical vertebrae sites in the same patients. In total, 31 patients with 45 mandibular fractures treated with RIF underwent presurgical and postsurgical CT examinations.

A Rare Case of Recurrent Temporomandibular Joint Dislocation Associated with Pneumatized Articular Eminence. Surgical Treatment by Eminoplasty with Miniplates.

Performing a surgical treatment for TMJ dislocation combined with pneumatized articular eminence is a technical challenge for the surgeon, as this condition has a low population frequency. This article aimed to present one case of recurrent temporomandibular joint dislocation treated by eminoplasty with miniplates in a patient affected by bilateral pneumatized articular eminence. After 15 months of follow-up, the patient presented approximately 43 mm of interincisal distance.

Complications on maxilar impaction: A systematic review and meta-analysis.

Objectives: Maxillary impactions are seen as an orthognathic surgical movement that increases the number of complications. The aim of this paper is to research literature on this topic, with special attention to avoiding of complications.

Methods: A systematic review was carried out according to the PRISMA guidelines.

An Extraoral Surgical Approach to Treat Chronic Submandibular Sialolithiasis - A Case Series.

Sialolithiasis is the most common cause of sialadenitis in the submandibular gland, in which the highest incidence of this condition occurs, among the major salivary glands. This could be explained by the anatomy of Wharton's duct, and the chemical composition of the saliva produced by this gland. There are several alternatives and techniques for the treatment of sialolithiasis, including lithotripsy, sialoendoscopy, and conservative removal of the sialoliths or complete removal of the submandibular gland, through the transoral and extraoral routes for access to the gland.

Myositis Ossificans Traumatica of the Temporal Muscle: a Case Report and Literature Review Emphasizing Radiographic Features on Computed Tomography and Magnetic Resonance Imaging.

Objectives: Heterotopic bone formation within a muscle is designated as 'myositis ossificans', and it is associated with multiple aetiologies, such as trauma, genetic predisposition, post-infection, or undetermined causes. When the disease develops as a result of a trauma, the myositis ossificans is classified as 'myositis ossificans traumatica'. In this case report, a case of myositis ossificans traumatica is described, emphasizing its imaging features.

Maxillary Sinus Natural Killer/T-Cell Extranodal Lymphoma Mimicking a Dentoalveolar Abscess.

Extranodal natural killer/T-cell lymphoma (ENKL) is an aggressive and infrequent malignant neoplasm. Early sinonasal ENKL clinical symptomatology is often not specific which can mimic several clinical odontogenic processes such as dentoalveolar abscesses. A 41-year-old female was referred to our institution due to facial pain with skin rash, fever, and intraoral swelling in the left side of the maxillary region.

Antibiotic therapy in fully impacted lower third molar surgery: randomized three-arm, double-blind, controlled trial.

Purpose: The aim of this study was to evaluate the efficacy of three drug protocols in patients undergoing extraction of fully impacted lower third molars.

Methods: Eighty surgeries were performed on healthy patients using three randomized double-blind drug protocols: group 1 (G1), amoxicillin (1 g) 1 h before surgery + 500 mg 8/8 h for 7 days; group 2 (G2), 1-g amoxicillin 1 h before surgery plus placebo, with identical appearance to G1, 8/8 h for 7 days; and group 3 (G3), placebo 1 h before surgery and 500 mg 8/8 h for 7 days. The primary outcome criterion was mouth opening, and the secondary outcome criteria were facial edema and pain.

Heterotopic gastrointestinal mucosa in the oral cavity of adults.

Heterotopic gastrointestinal mucosa (HGM) is a rare entity observed in the head and neck region and occurs more frequently in male infants and children. The floor of the mouth and anterior aspects of the tongue are the most commonly affected sites. Histologically, HGM resembles gastric, intestinal or colonic mucosa with areas of squamous epithelium, which can be cystic or solid.
