Closure of an Oroantral Communication Using Bichat’s Fat Pad: A Case Report

An oroantral communication (OAC) is a pathological connection between the oral cavity and the maxillary sinus.When it fails to close spontaneously, it remains open and epithelializes, leading to the development of an oroantral fistula.It is a common complication following the extraction of maxillary premolars and molars due to the anatomical proximity of the root apices of these teeth to the maxillary sinus.Several surgical options exist for its management, particularly the use of Bichat's fat pad, which has proven to be an effective and reliable technique.In this article, we report a case of OAC successfully treated by traction of Bichat's fat pad.
