A Modified Approach for the Closure of Oral Sinus Communications

The connective flap was harvested from the deeper area of the palatal mucosa. Pedicle flap dimensions were reported using the periodontal probe. The flap was then rotated to cover the oro antral communication (OAC) area. The rotation could be in mesial or distal direction, related to OAC position and for the convenience of the donor site. The connective palatal flap was sutured to the buccal periostium using mattress sutures.
