Introduction: Oro-antral fistulas (OAF) produce infections in the maxillary sinus due to contamination with bacteria from the oral cavity, saliva and or food debris.They are most frequently caused by extraction of upper molars or premolars or due to failure in the osseointegration of dental implants.The treatment consists of the repair of the oral sinus communication and drainage of the sinus infection.Objective: To determine the success rate of the repair of oral-sinus communications greater than 5 mm with the Bichat ball (BB) and vestibular mucoperiosteal flaps.Methods: Data from patients who were treated for oroantral fistulas with Bichat ball (BB) and vestibular mucoperiosteal flaps between March 2019 and August 2022 were prospectively collected and analyzed.Results: Fifteen patients were treated, eleven women and four men.The success rate of closure of the OAF with the Bichat ball and vestibular flaps was 93.33% (14/15).The incidence of flap necrosis was 13.33% (2/15). Conclusions:The success rate of closure of OAF that we had with the Bichat ball and vestibular flaps was 93.33% (14/15).The use of the BB and vestibular mucoperiosteum flaps allowed to close the OAF in two planes.Due to its low morbidity, simple dissection, and high effectiveness, we believe that it is the surgical technique of choice to repair OAF.
