摘要

Purpose

This study aimed to assess the prevalence, thickness and course of the alveolar antral artery (AAA) and its anatomical position to maxillary sinus, molars and premolars using Cone-Beam Computed Tomography (CBCT).

Materials and methods

In this retrospective study, CBCT scans from patients at the Dental School of Hamadan University of Medical Sciences, Iran, were investigated between 2019 and 2023. Participants were over 18 years of age, without systemic diseases, sinus surgery, or jaw fractures. High-quality CBCTs were taken and reconstructed in 1 mm intervals using OnDemand software. Bilateral measurements of the AAA were made at the first and second premolars and molars in coronal, sagittal, and axial views. The AAA’s thickness, course (intrasinus, intraosseous, or superficial), and distance to the maxillary sinus floor were assessed. The prevalence of AAA was examined across age, gender, and dental status, and lateral wall thickness at 5 mm above the sinus was measured.

Results

A total of 191 CBCT images were examined, of which 87 (45.5%) were male. The average age of the patients was 46.04 ± 12.62 years with a range of 18 to 73 years, and AAA was detected in 128 (67%) of cases. The average thickness of AAA in men and women was 0.58 ± 0.17 and 0.51 ± 0.15 mm, respectively. The distance between AAA floor and maxillary sinus floor was 5.9 ± 3.45 and 7.75 ± 3.92 mm in patients with and without teeth, respectively. The intrasinus, intraosseous, and superficial AAA courses were 45.75%, 47.8%, and 6.45%, respectively.

Conclusion

The prevalence of AAA was 67%, with no statistically significant differences observed between genders, age groups, dental locations, or dental status. On average, AAA was 0.07 mm thicker in men, and its distance from the sinus floor was 31.45% greater in edentulous patients. AAA followed an intraosseous or intrasinus route in 93% of cases, with a superficial route in fewer than 7%.
