- Resumen
The second most common complication during sinus lift surgery procedures is severe bleeding. Anatomical studies have consistently detected intraosseous anastomosis of the posterior superior alveolar artery in the area of the lateral wall of the maxillary sinus where the antrostomy use to be performed but CThe second most common complication during sinus lift surgery procedures is severe bleeding. Anatomical studies have consistently detected intraosseous anastomosis of the posterior superior alveolar artery in the area of the lateral wall of the maxillary sinus where the antrostomy use to be performed but CT scans failed to identify these structures in many patients.
In this investigation it was carry out a Systematic review and meta-analysis to assess the prevalence of this artery in the lateral sinus wall of the maxillary sinus using CT/CBCT in patients candidates for sinus lift surgery. There were also perform three retrospective observational studies of a sample of patients candiates of sinus lift surgery procedures using CBCT explorations from the Radiology Unit of the School of Medicenie and Dentisty of the USC. 466 maxilary sinus where studied with a triple objetive: -To study the variables related to the prevalence of the artery detection and to study the variables related to its detection while allowing for potential confounding factors.
-To identify the variables related to patients at risk of iatrogenic bleeding with the artery located within 15mm of the bony crest and explain the course variations beyond the safe distance.
-To identify variables related to the diameter of the artery to identify profiles at risk for bleeding complications. .
