Prevalencia de anastomosis endoósea de la arteria maxilar por tomografía Cone-Beam en Studio 3D.

Abstract

Introduction: Knowing the prevalence of maxillary artery endoosseous anastomosis is extremely important when planning a maxillary sinus surgery to avoid intraoperative complications. Materials and methods: This descriptive, cross-sectional, and retrospective study determining the prevalence of maxillary artery endoosseous anastomosis in subjects from Guayaquil, Ecuador. 80 CT scans were taken at random from the 3D Studio radiology center. The prevalence of the anastomosis was taken into account, as well as its distance from the maxillary sinus floor, the lateral aspect and its ratio in millimeters with the crests of pieces 16, 17, 26, 27. Results: Within 80 scans analyzed, included 42 who presented the anastomosis (52.5%). A mean of 6.00 mm in relation to the floor of the right maxillary sinus and 6.04 mm with the left one was observed. Its relation to the lateral aspect of the right maxillary sinus with a mean of 0.94 mm and 0.91 mm on the left side. Its relation with the alveolar crest of the pieces 16 was 13.85 mm, with the 17 was 14.73 mm, with the 26 was 13.82 mm and the 27 was observed 14.53 mm. Discussion: Within the maxillary sinus vascularization, this anastomosis must be taken into account for a correct surgical planning and avoid intraoperative and postoperative complications that can lead to treatment failure.
