Inverted Periosteal Flap vs Buccal Advancement Flap for Oroantral Communication Closure
Comparison of Inverted Periosteal Flap Versus Buccal Advancement Flap for Closure of Post-Extraction Maxillary Sinus Perforation: A Randomized Controlled Trial
調査の概要
詳細な説明
Oroantral communication is an abnormal connection between the oral cavity and the maxillary sinus, most commonly occurring after extraction of maxillary posterior teeth. If not closed properly, it may lead to oroantral fistula or maxillary sinus complications.
This randomized controlled clinical study will compare the inverted buccal periosteal flap with the conventional buccal advancement flap for closure of recent post-extraction oroantral communications. The study will include 24 patients with communications measuring 3-6 mm and diagnosed within 48 hours after non-surgical extraction.
Participants will be randomly divided into two groups. In the test group, closure will be performed using the inverted buccal periosteal flap, where the periosteal layer is dissected, inverted over the defect, and sutured to the palatal tissue without tension. In the control group, closure will be performed using the buccal advancement flap, where a buccal mucoperiosteal flap is advanced palatally and sutured to cover the communication.

説明
Inclusion Criteria:
- Presence of an oroantral communication (OAC) with a diameter between 3-7 mm.
- Communication resulting from extraction of posterior maxillary teeth (first molar, second molar, third molar, or second premolar).
- Recent perforation occurring no more than 48 hours prior to surgical intervention.
Exclusion Criteria:
- Presence of foreign bodies or residual tooth fragments within the maxillary sinus.
- Presence of systemic diseases that could impair wound healing (e.g., uncontrolled diabetes, immunosuppression).
- History of maxillary sinusitis prior to the perforation.
- Presence of periapical lesions or cysts at the extraction site.
- Smokers.

実験的:Inverted Buccal Periosteal Flap
Participants in this arm will receive surgical closure of the post-extraction oroantral communication using the inverted buccal periosteal flap.
A full-thickness mucoperiosteal flap will be elevated, the periosteal layer will be dissected and inverted over the defect, then sutured to the palatal tissue to achieve tension-free closure.

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.

アクティブコンパレータ:Buccal Advancement Flap
Participants in this arm will receive surgical closure of the post-extraction oroantral communication using the conventional buccal advancement flap.
A buccal mucoperiosteal flap will be elevated, advanced palatally, and sutured to the palatal mucosa to cover the communication.

Successful Closure of Oroantral Communication
時間枠:1 week, 15 days, and 45 days after surgery.
|
Successful closure will be assessed clinically by confirming the absence of oroantral fistula formation, absence of fluid leakage through the nose, and absence of air leakage or air bubbles during the Valsalva test.
|
1 week, 15 days, and 45 days after surgery.

Postoperative Pain
時間枠:Postoperative days 1, 3, 5, and 7.
|
Postoperative pain will be assessed using the Visual Analog Scale.
The scale ranges from 0 to 10, where 0 indicates no pain and 10 indicates the worst possible pain.
Higher scores indicate a worse outcome.
|
Postoperative days 1, 3, 5, and 7.
|
|
Postoperative Facial Edema
時間枠:Postoperative days 1, 3, and 5.
|
Facial edema will be assessed using extraoral linear measurements between fixed facial reference points.
The measured distances will be used to estimate postoperative facial swelling and compare changes between the two study groups.
Higher values indicate greater facial edema and therefore a worse outcome.
|
Postoperative days 1, 3, and 5.
