Double-Layer Closure Technique Using Buccal and Palatal Flaps for Oroantral Fistula
Condition(s) studied
Investigational drug(s) / intervention(s)
Closure was performed using split-thickness buccal and palatal mucosal flaps with a subepithelial palatal connective tissue graft: 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.
Study 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.
