Body
Objectives: Assessment of the maxillary sinus anatomy is important because of the close anatomical
relationship of posterior maxillary teeth with the maxillary sinus. Posterior superior
alveolar artery (PSAA) is the branch of the maxillary artery that supplies lateral sinus wall
and overlying membrane. The purpose of this study was to evaluate the location of the PSAA
and its relationship to the alveolar ridge and prevalence of sinus pathology and septa by cone
beam computed tomography (CBCT).
Methods: The study group consisted of 135 CBCT scans (270 sinuses) obtained from the archive
of the dentomaxillofacial radiology department.
The distance between the lower border of the artery and the alveolar crest, bone height from
the sinus floor to the ridge crest, distance of the artery to the medial sinus wall, the diameter
and location of the artery were determined; occurrence of septa and pathology were recorded
from CBCT scans.
Results: PSAA was observed in 80.3 % of all sinuses and 71.1 % of artery was intraosseous
and the diameter was mostly < 1mm (68.9 %).The prevalence of sinus septa was 55.2% and
sinus pathology was 57.4%. Mean age was 43.07±17.55. No significant correlation was found
between the presence of artery and age/gender (p>0.05). There was statistically significant
difference between location of the artery and gender (p
