ABSTRACT
 Objective: The perfusion of the lateral wall of the maxillary sinus and the overlying membrane is provided by the posterior superior alveolar artery (PSAA) and infraorbital artery. The aim of our study is to evaluate the incidence, location, and diameter of PSAA in the lateral wall of the maxillary sinus due to its importance in surgical approaches involving the maxillary sinus. Material and Methods: In this study 300 maxillary sinuses were retrospectively analyzed in cone beam computed tomography (CBCT) images of 150 individuals. The presence of PSAA on the lateral wall of the maxillary sinus, its location was evaluated and the diameter and its perpendicular distance to the inferior and medial walls of the maxillary sinus and the alveolar crest were measured on CBCT images. Data were statistically analyzed with descriptive statistics, Kruskal-Wallis, Mann-Whitney U, and Pearson chi-square tests. Results: PSAA was detected in 205 (68.3%) of 300 maxillary sinus. The PSAA diameter was measured as a minimum of 0.2 mm and a maximum of 4.10 mm. PSAA was observed as 20% superficial, 53.7% intraosseous and 26.3% intrasinus positioned. A statistically significant relationship (p=0.00) was found between PSAA diameter, the perpendicular distances of PSAA from the inferior wall and alveolar crest, and gender. The increase in PSAA diameter and PSAA distance from the alveolar crest with age was found statistically significant (p=0.02, p=0.34). Conclusion: It is important to know the anatomy of the region to perform preoperative CBCT examination to achieve higher success in surgical procedures and to prevent vascular damage in the maxillary sinus.

Keywords: Maxillary artery; cone beam computed tomography; maxillary sinus
ÖZET
 Amaç: Maksiller sinüsün lateral duvarı ve üzerini örten membranın perfüzyonu, posterior superior alveolar arter (PSAA) ve infraorbital arter tarafından sağlanmaktadır. Çalışmamızın amacı, maksiller sinüsü ilgilendiren cerrahi yaklaşımlardaki önemi nedeniyle PSAA'nın maksiller sinüs lateral duvarındaki görülme sıklığını, yerleşimini ve çapını değerlendirmektir. Gereç ve Yöntemler: Bu çalışmada, 150 bireye ait konik ışınlı bilgisayarlı tomografi (KIBT) görüntülerinde 300 maksiller sinüs retrospektif olarak analiz edilmiştir. KIBT görüntüleri üzerinde maksiller sinüs lateral duvarında PSAA'nın varlığı, konumu değerlendirilmiş ve PSAA'nın çapı, PSAA'nın maksiller sinüs inferior, mediyal duvarlarına ve alveoler krete olan dik uzaklıkları ölçülmüştür. Veriler tanımlayıcı istatistikler, Kruskal-Wallis, Mann-Whitney U ve Pearson ki-kare testleri kullanılarak istatistiksel olarak analiz edilmiştir. Bulgular: 300 maksiller sinüsün 205'inde (%68,3) PSAA tespit edilmiştir. PSAA çapı minimum 0,2 mm, maksimum 4,10 mm olarak ölçülmüştür. PSAA'nın %20 yüzeyel, %53,7 intraosseöz ve %26,3 intrasinüs yerleşimli olduğu görülmüştür. PSAA çapı, PSAA'nın inferior duvara ve alveol tepesine dik uzaklıkları ve cinsiyetler arasında istatistiksel olarak anlamlı ilişki (p=0,00) bulunmuştur. Yaşla birlikte PSAA çapındaki ve PSAA'nın alveoler krete olan uzaklığındaki artış istatistiksel olarak anlamlı bulunmuştur (p=0,02, p=0,34). Sonuç: Cerrahi işlemlerde daha yüksek başarı elde etmek ve maksiller sinüste damar hasarını önlemek için ameliyat öncesi KIBT incelemesi yapmak için bölgenin anatomisini bilmek önemlidir.
