Objective: Oroantral fistula(OAF) is pathological pathway that connects the oral cavity and the maxillary sinus. Due to the close relationship of the maxillary sinus with the maxillary molar and premolar teeth, OAF may occur due to pathological conditions in these teeth or post-surgical sinus membrane perforation. An opening larger than 5 mm in diameter cannot close on its own and must be closed with an appropriate surgical procedure.In this case, treatment of OAF developing 1 month after tooth extraction with buccal fat pad(BFP) will be explained.
Case: A 37-year-old male patient without any systemic disease was admitted to our clinic with complaints of bad breath and liquid drinks coming into the nose after tooth extraction in the right maxillary region 1 month ago. OAF was diagnosed as a result of clinical and radiological examination.For the treatment of OAF, the patient was processed under local anesthesia and the mouth of the fistula was cut with a scalpel. Mucoperiosteal flap was then reflected.BFP was exposed by blunt dissection from relevant region. This adipose tissue was carefully advanced to close the opening and sutured to the palatal mucosa with 4.0 vicryl sutures. Then the flap was brought back to the same position and sutured with 3.0 silk suture. Necessary medications were prescribed to the patient. No complications were encountered. The follow-up of patient continues.
Conclusion: Untreated OAF can cause speech and feeding problems, facial pain, and chronic sinusitis.Closing these openings with BFP is a common technique.BFP is rapid in epithelialization because it has good blood supply.
