The use of extended nasolabial flap in reconstruction of head and neck defects has proved to be efficacious and reliable.The versatility of this flap has been attributed to the fact that there is often abundant non-hair bearing skin in this well vascularised region. Flap elevation is quick and simple, with minimal donor site deformity and rapid post-operative rehabilitation. Also the proximity to the defect and achievement of good cosmetic result with preservation of function and least distortion of anatomy makes it the flap of choice. The aim of treating oral submucous fibrosis is to provide relief to the patient from the limitations of mouth opening and burning sensation. Numerous treatment modalities (both medical and surgical) have been employed for the treatment of OSMF. The purpose of this study was to evaluate the role of extended nasolabial flaps for reconstruction of buccal mucosal defects after surgical excision of fibrous bands in patients with oral submucous fibrosis.
