Double Layer, Oroantral Fistula
Conditions
Keywords
oroantral fistula, double layer closure, buccal flap, palatal flap, rotational palatal connective tissue flap
Brief summary
A prospective clinical case series was conducted involving twelve patients with oroantral fistulas ≥5 mm in diameter. Closure was performed using split-thickness buccal and palatal mucosal flaps with a subepithelial palatal connective tissue graft rotated to cove the bony defect and sutured to the buccal periosteum as the first layer, then the buccal mucosa sutured with the palatal one . Clinical evaluations were conducted at regular intervals over a 3-month postoperative period, assessing wound healing, fistula recurrence, pain, facial edema, infection, and donor site morbidity.
Detailed description
The proposed double-layer technique achieved high success rates in closing oroantral fistulas with minimal postoperative complications, reduced facial edema, and better preservation of vestibular depth compared to conventional techniques. A prospective clinical case series was conducted involving twelve patients with oroantral fistulas ≥5 mm in diameter. Closure was performed using split-thickness buccal and palatal mucosal flaps with a subepithelial palatal connective tissue graft rotated to cove the bony defect and sutured to the buccal periosteum as the first layer, then the buccal mucosa sutured with the palatal one . Clinical evaluations were conducted at regular intervals over a 3-month postoperative period, assessing wound healing, fistula recurrence, pain, facial edema, infection, and donor site morbidity. This technique demonstrated reliable, tension-free closure with excellent clinical outcomes, reduced postoperative facial edema, and preserved vestibular depth, supporting its potential as an effective and safe surgical option for managing oroantral fistulas. The purpose of the present study was explained to the patients and informed consents were obtained according to the guidelines on human research adopted by the Research Ethics Committee, Faculty of Dentistry, Tanta University.
