Knowledge of variations in arteries and nerves of infratemporal fossa may be helpful in radical neck dissection and in dental procedures to avoid the complications. We present an unusual case in which maxillary artery was found deep (medial) to lateral pterygoid muscle. Lingual nerve originated from two roots: anterior and posterior. Anterior root originated from common trunk and the posterior root directly from mandibular nerve. Inferior alveolar nerve was a continuation of the common trunk. Branches of mandibular nerve formed a loop through which passed the second part of maxillary artery. The clinical significance of the present variations has been discussed.

Aim: This study aimed to evaluate the prevalence, location and diameters of Posterior superior alveolar artery (PSAA) and Infraorbital foramen (IOF) to find out whether there is any relationship between PSAA and IOF, and to predict their location relative to each other in surgical procedures by using cone beam computed tomography (CBCT).
Material And Method: Bilateral maxillary sinuses were analysed retrospectively in 170 patients with no missing teeth in the maxillary posterior region. The largest locations of PSAA and IOF in the maxillary sinus were determined and their size, shape, location in relation to the teeth and distances from anatomical points were evaluated.

Objective: This study aims to determine the anatomical relationship between the posterior superior alveolar artery (PSAA) and the lateral wall of the maxillary sinus during preoperative radiological evaluations in the posterior maxillary dental region, as well as to evaluate the prevalence of PSAA and its potential associations with sinus pathologies.
Materials And Methods: This retrospective study is based on the analysis of Cone-Beam Computed Tomography (CBCT) data from 510 sinuses of 255 patients. The visibility of the PSAA vascular canal, artery diameters, vertical distance between the alveolar crest and the artery, and the distance to the sinus floor were measured in coronal sections.
Background: It is generally accepted that the greater palatine nerve and artery supply the palatal mucosa, gingiva, and glands, but not the bone or tooth adjacent to those tissues. When the bony palate is observed closely, multiple small foramina are seen on the palatal surface of the alveolar process. The authors hypothesized that the greater palatine nerve and artery might supply the maxillary teeth via the foramina on the palatal surface of the alveolar process and the superior alveolar nerve and artery.

BACKGROUND Carotid artery injury has an incidence of 0.2% in the National Trauma Data Bank. The true incidence of intracranial carotid injury is unknown but can be estimated at less than one in 1000 trauma-related inpatient admissions in America.

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.
