Inverted Periosteal Flap vs Buccal Advancement Flap for Oroantral Communication Closure
Sponsor: Arab International University
Summary
This randomized controlled clinical study will evaluate the effectiveness of the inverted buccal periosteal flap in closing recent post-extraction oroantral communications and compare it with the conventional buccal advancement flap. The study will include 24 patients who develop an oroantral communication measuring 3-6 mm after non-surgical extraction of maxillary posterior teeth. Participants will be randomly allocated into two groups: the test group treated with the inverted buccal periosteal flap, and the control group treated with the buccal advancement flap. The primary outcome will be successful clinical closure of the communication, assessed by absence of oroantral fistula, nasal fluid leakage, and air leakage during the Valsalva test. Secondary outcomes will include postoperative pain, facial edema. Patients will be followed for up to 45 days after surgery.

Conditions
Interventions
Inverted Buccal Periosteal Flap
Surgical closure of post-extraction oroantral communication using an inverted buccal periosteal flap. A full-thickness mucoperiosteal flap will be elevated, followed by dissection of the periosteal layer from the overlying mucosa. The periosteal flap will then be inverted over the defect and sutured to the palatal tissue to achieve tension-free closure.
Buccal Advancement Flap
Surgical closure of post-extraction oroantral communication using the conventional buccal advancement flap. A buccal full-thickness mucoperiosteal flap will be elevated, released by periosteal scoring, advanced palatally, and sutured to the palatal mucosa to cover the communication.
