Objective: To evaluate the presence, positioning and diameter of the posterior superior alveolar artery in relation to the alveolar ridge using cone beam computed tomography.
Materials and Methods: 100 computed tomography scans (200 maxillary sinuses) of patients (50 males and 50 females) undergoing maxillary sinus lift treatment were included in this study. The presence of the artery, its diameter and position in relation to the maxillary sinus, and the distance between the alveolar ridge and the inferior base of the artery were evaluated.
Results: The artery was detected in 45% of cases, and 46.67% were located in the external cortical in the maxillary sinus. The mean distance between the alveolar crest and the inferior base of the posterior superior alveolar artery was 15.5 ± 4.7mm. The mean diameter of the posterior superior alveolar artery was 0.9 ± 0.3mm. No correlation was found between artery diameter and patient age (Pearson correlation test r = 0.12, p = 0.26). No correlation was also found between the distance to the artery and age (Pearson correlation test r = 0.04, p = 0.69).
Conclusions: Within the limits of this study it can be concluded that posterior superior alveolar artery was found with relatively large frequency in the maxillary sinus, mainly in the external cortical, presenting a considerable diameter. From this perspective, careful preoperative analysis is recommended to avoid bleeding in the maxillary sinus lift procedure.
