Arterial blood architecture of the maxillary sinus in dentate specimens

Abstract

AimTo describe vascular anatomy of the maxillary sinus in dentate specimens dissected from human cadavers.MethodsTwenty dentate maxillary specimens were dissected, anatomically prepared, and injected with liquid latex for a better visualization of the maxillary sinus artery.ResultsWe 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.ConclusionThese 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.

Detection of the posterior superior alveolar artery in the lateral sinus wall using computed tomography/cone beam computed tomography: a prevalence meta-analysis study and systematic review

“…25 Another study, aiming to identify the branches of the maxillary artery, did not provide information on the prevalence within the sinus lateral bony wall. 26 One more report was discarded because it reported surgical information from a series of cadaveric material, 13 and five articles describing a prevalence of 100% of PSAA within the sinus wall, based on anatomical dissections, were also excluded from this metaanalysis 6,7,11,25,27 (Table 1). Finally, another paper was discarded because CT scans were performed to investigate sinus disorders.…”

The Relationships of the Maxillary Sinus With the Superior Alveolar Nerves and Vessels as Demonstrated by Cone‐Beam CT Combined With μ‐CT and Histological Analyses

“…The middle superior alveolar artery branches from the infraorbital artery and runs inferiorly along the lateral wall of the maxillary sinus toward the region of the canine and lateral incisor teeth and anastomoses with the anterior and posterior superior alveolar arteries (Standring, ). Although previous studies have reported an anastomosis between the posterior superior alveolar artery and infraorbital artery (Solar et al, ; Traxler et al, ; Kqiku et al, ), variations in maxillary sinus vascular connections (Ella et al, ; Sato et al, ), and the prevalence, diameter, and location of the posterior superior alveolar artery and its relationship with the alveolar ridge (Elian et al, ; Guncu et al, ; Jung et al, ; Ilguy et al, ), these studies have primarily focused on the vascular injury during sinus floor augmentation and have failed to clarify the topographical relationships between the superior alveolar arteries and the maxillary sinus.…”

Maksi̇ller Si̇nüsün Radyoloji̇k Tani Yöntemleri̇ni̇n Ve Anatomi̇k Li̇mi̇tasyonlarinin Tedavi̇ Planlamasinda Rolü

“…Maksiller kemiğin nekrozu ve kanama komplikasyonlarını önlemek amacıyla cerrahi tedaviler (osteotomi, endodontik cerrahi, dental implant, yaralanma tedavileri) sırasında maksiller sinüsün vaskülarizasyonu, PSAA'nın alveolar kemikten vertikal yüksekliği ve maksiller dişlerle seviyesi hakkında bilgiye sahip olmak önemlidir. 56,57 PSAA ve IOA'nın maksimum çapı 2 mm ile 2,7 mm arasındadır. Büyük çaplı arterler daha fazla kanama problemine yol açacağından sinüs ogmentasyonunda dikkatli olunmalıdır.…”
