A buccosinusal fistula consists of a permanent communication between the oral cavity and the sinus. For the treatment of this complication, three modalities can be highlighted: sliding of the vestibular flap, palatal flap, or graft of cheek adipose tissue. Each of these treatment forms has disadvantages, which led to the development of the zetaplasty technique. Patient C.M., a 57-years-old male, sought the Surgery Clinic of the Federal University of Alfenas for the treatment of a broad buccosinusal communication. After anesthesia, a perilesional incision followed by an extended incision anteriorly to expose the alveolar ridge for regularization. Additional relief incisions were executed to mobilize the vestibular and palatal flaps. The proposed technique aims to obtain relief incisions in the vestibular and palatal areas from the freshened wound margins, allowing the sliding of the flaps in the zetaplasty technique. There has been no need for surgical re-intervention up to the present moment.
