Anatomical considerations of the posterior superior alveolar artery in dentate and edentulous patients using cone beam computed tomography
The Posterior Superior Alveolar Artery plays a vital role in sinus floor elevation, although it is often injured during surgery due to bone resorption and pneumatization of the maxillary sinus.

| Sumario: | The Posterior Superior Alveolar Artery plays a vital role in sinus floor elevation, although it is often injured during surgery due to bone resorption and pneumatization of the maxillary sinus. The objective of this study was to analyze the topography of the artery using cone beam computed tomography and relating it to sex, age, the position of premolars and upper molars, and the presence/ absence of teeth. A total of 243 CT scans were evaluated, and a total of 486 maxillary sinuses, both right and left. The presence, diameter, and location of the artery were analyzed. Both diameter and location were related to the position of the upper premolars and molars, their presence/absence, as well as sex and age. The rate of presence of the artery was 61.8%. The artery presented a predominantly intraosseous location (64.3%) associated with the premolars (p < 0.05). The average diameter was 1.45 ± 0.26 mm and significant differences were found concerning sex, age, presence/absence of teeth, and position of the upper premolars and molars. The current study showed that the predominant location of the artery in the premolars was intraosseous, while in the molars it tended to be intrasinusal. In addition, the diameter was related to sex, age, and presence/absence of teeth, and slightly larger diameters were found on the right side, although this did not mean that there were significant differences between each premolar or molar with its counterpart on the opposite side. |
