Oroantral fistula: broad-contact closure

Area of Science:

• Oral and Maxillofacial Surgery
• Surgical Techniques
• Reconstructive Surgery

Background:

• Oroantral fistulae (OAFs) are abnormal communications between the oral cavity and the maxillary sinus.
• Medium-sized OAFs often require surgical intervention for closure.
• Traditional techniques may have limitations in flap mobility and patient recovery.

Purpose of the Study:

• To describe a modified Rehrmann's buccal advancement flap technique for treating medium-sized oroantral fistulae.
• To outline the advantages and disadvantages of this modified technique compared to traditional methods.

Main Methods:

• A modified Rehrmann's buccal advancement flap technique was employed.
• Surgical procedure details focus on flap design and advancement for OAF closure.

Main Results:

• The modified technique demonstrated effectiveness in treating medium-sized oroantral fistulae.
• Identified advantages include successful fistula closure.
• Disadvantages noted were a slightly longer operating time and temporary reduction in buccal sulcus depth due to extended flap mobilization.

Conclusions:

• The modified Rehrmann's buccal advancement flap is a suitable option for medium OAFs.
• The temporary shallowing of the buccal sulcus resolves within two months post-surgery.
• This technique offers a valuable alternative for oroantral defect reconstruction.
