Purpose: Knowledge of the blood supply to the sinus is of importance in sinus augmentation, both as it pertains to vascularization of the sinus graft and as its location relates to the position of the required lateral osteotomy. The purpose of this study was to investigate the distribution of the endosseous branches of the maxillary artery in the area of the proposed lateral window.
Materials And Methods: Fifty computerized tomographic (CT) scans from 625 available patients undergoing sinus augmentation surgery at the New York University Department of Implant Dentistry were chosen at random for evaluation. In those cases where the maxillary artery could be identified, measurements were taken to determine the distance between the alveolar crest and the lower border of the vessel.
Results: The vessel was radiographically identified in 51.4% of right sinuses and 54.3% of left sinuses in the 50 CT scans. The average height of the artery from the alveolar crest was 16 mm (+/- 3.5 mm).
Discussion: and
Conclusions: Because of its location, the intraosseous artery has the potential to cause bleeding complications in approximately 20% of normally positioned lateral window osteotomies. Although a previous anatomic study on cadavers identified the vessel in 100% of the specimens, it could only be visualized in 53% of the CT scans in the present series.

The palate's morphological characteristics are of great importance, especially in periodontology, where the palatine tissue represents a source of tissue graft for multiple mucogingival surgeries. This study aimed to estimate the amount of donor tissue available through the average palatal height and average location of the greater palatine artery in the Saudi population according to age and gender. Digital casts for adult Saudi patients at the age of 18-60 years old with a mean age of 37.

A 73-year-old male with a history of incidentally diagnosed Paget disease of bone affecting the skull and left orbit 2 years prior presented with 3 months of vision loss, proptosis, and periorbital swelling of the OS. Examination showed best-corrected Snellen visual acuity of 20/150 in the affected eye, intact motility, 7 mm of relative proptosis, significant dilated and tortuous "corkscrew" conjunctival vessels, serous choroidal and retinal detachments, optic nerve hyperemia, and venous tortuosity and dilation. Although the bony lesions in the left orbit were stable from 1 year prior on imaging, the diagnostic angiogram demonstrated osseous blush and hypervascularity of the lesion.

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.
