Many authors have studied variation in the maxillary artery but there have been inconsistencies between reported observations. The present research aimed to examine the courses and branching patterns of the trunk and branches of the maxillary artery in a large sample of Japanese adult cadavers. The course of the maxillary artery should be reclassified into seven groups as a clear relationship was found between the origin of the middle meningeal artery and the course of the maxillary artery. This indicates that conventional theory about the formation of the maxillary artery, which was considered to be a direct derivative of the stapedial artery, might be inaccurate. Many variations in the origin of the inferior alveolar artery were found. Notably, the inferior alveolar artery origin from the external carotid artery and a double origin of the inferior alveolar artery was also observed. Thus, the maxillary artery might be derived from a combination of both the external carotid and stapedial arteries.

Department of Ophthalmology, Duke University, Durham.
Purpose: Soft-tissue filler injections, particularly hyaluronic acid, are popular for temple volume restoration. Although uncommon, this area poses risk for vision loss from embolic occlusion. Guidelines recommend injecting into the supraperiosteal plane for safety; however, the deep temporal arteries (DTAs) in this plane pose a risk.

Background: The submental artery island flap (SIF) is a valid option for palatal reconstruction. However, the main limitation for its application for palatal defects is the arc of rotation. A novel modification for tunneling of the antegrade design of SIF that allows a compliant easy reach to the defect is described.

Objective: Multiple techniques have been used to treat trigeminal neuralgia (TGN), including pharmacotherapy, radiosurgery, rhizotomy and microvascular decompression (MVD). Blood vessels are considered to be the most common cause of offense and compression to trigeminal nerve. We aimed to determine the causes of classic TGN and efficacy of MVD.
