Summary
This study tests a two-layer surgical technique to close oroantral fistulas—abnormal openings between the mouth and sinus cavity. Twelve patients will receive the procedure using tissue flaps from the cheek and palate. Researchers will monitor healing, pain, swelling, and whether the fistula returns over three months.
