Article Abstract
The masseteric nerve is often used as a donor nerve in the treatment of facial paralysis. Even if several anatomical studies described landmarks for its identification, their main disadvantages are the anatomical variability and the changes due to surgery. Sixteen dissections were performed on cadaveric specimens. The masseteric muscle (MM), the zygomatic arch (ZA), the masseteric nerve (MN) and the zygomatic branch of the facial nerve (ZB) were identified and their relationships were measured. The relationships between MN and ZB resulted to be constant, with MN intersecting ZB at a depth of 0,78 cm in the muscle, 1,6 cm below ZA and 0,8 cm from the posterior border of MM. The measures obtained demonstrated as the main zygomatic branch of the facial nerve can be a suitable landmark for the identification of the masseteric nerve, with no variations due to the surgical procedure or patient characteristics.

Enhancing submandibular gland resection: A retrospective study on the efficacy of the ORBEYE 3D exoscope.
Oral Maxillofac Surg

Department of Otolaryngology, Head and Neck Surgery, Kansai Medical University, Shinmachi 2-5-1, Hirakata-city, Osaka, Japan.
Purpose: For submandibular gland resection, conventional surgery with the naked eye remains the standard. With its excellent automatic focus and high magnification, the ORBEYE 3D exoscope enables precise submandibular gland resection with less stress. Therefore, we aimed to examine the usefulness of the exoscope in submandibular gland resection.

The purpose of this study was to assess the efficacy of a thermomechanical device (Buzzy, Pain Care Labs) for reducing pain associated with an IANB for pediatric dental patients.
Methods: A total of 30 children, 5 to 8 years of age undergoing bilateral mandibular dental treatment requiring IANBs, were included in this randomized crossover study.
Objective: Previous studies of nerve distribution in the orofacial complex have focused primarily on the anatomic courses of nerve fibers and have rarely addressed the density of nerve distribution. The nerve distribution in the mandible was described in only one report which showed an increase in nerve distribution density moving from the alveolar crest toward the inferior alveolar nerve. However, no previous reports have focused on the nerve distribution density in the maxilla.

Functional reconstruction of large mandibular defects, especially in young patients, presents a significant clinical challenge. The ideal approach should not only restore skeletal contour but also address nerve deficits and facilitate final occlusal rehabilitation, all while minimizing morbidity. This report describes a comprehensive, multi-staged strategy for such a case.

Background: Inferior alveolar nerve (IAN) injuries are common complications of mandibular orthognathic surgery. Selegiline has demonstrated neuroprotective effects in preclinical studies.
Objective: To evaluate the effect of oral selegiline hydrochloride on neurosensory recovery following bilateral sagittal split osteotomy.
