Abstract

Aim To describe vascular anatomy of the maxillary sinus in
dentate specimens dissected from human cadavers.
Methods Twenty dentate maxillary specimens were dissected,
anatomically prepared, and injected with liquid latex
for a better visualization of the maxillary sinus artery.
Results We found an intraosseous anastomosis in 100%
and an extraosseous anastomosis in 90% of the cases.
The anterior lateral wall of the maxillary sinus was transversed
by two anastomoses between the posterior superior
alveolar artery (PSAA) and the infraorbital artery (IOA).
The PSAA was divided into a gingival and dental branch.
The gingival branch anastomosed with the terminal extraosseous
branch of the extraosseous anastomosis (EOA)
and the dental branch with the intraosseous branch of the
intraosseous anastomosis (IOA). The mean distances from
the alveolar ridge to the extraosseus anastomosis were 16
mm for the second maxillary molar, 12.3 mm for the first
maxillary molar, and 13.1 mm for the second maxillary premolar.
The mean distances from the intraosseous anastomosis
to the alveolar ridge were 17.7 mm for the second
maxillary molar, 14.5 mm for the first maxillary molar, and
14.66 mm for the second maxillary premolar.
Conclusion These findings provide relevant data for clinical
dentistry in order to avoid bleeding complications and
minimize the risk of injury to the arterial network of the
maxillary sinus during surgical procedures in the dentate
maxilla region.
