Modified Buccinator Flap for Patients with Medication-Related Osteonecrosis of the Jaw: A Case Series

Surgical management of medication-related osteonecrosis of the jaw (MRONJ) includes eliminating infected and necrotic tissue, establishing a well-vascularized wound bed, and soft tissue closure. Success is improved by multilayered primary closure1-3 with local flaps. In 1989 Bozola4 first described the buccinator flap based on the buccal artery to close oral mucosal defects, then modified in 1991 by Carstens5 who introduced the buccinator musculomucosal island pedicle flap based on the facial artery.
