Surgical oncology and reconstructionClinical and Histological Basis for the Use of Nasolabial Tissues in the Surgical Management of Oral Submucous Fibrosis
Section snippets
Materials and Methods
Patients 17 to 45 years old with a complaint of restricted mouth opening or burning sensation of the buccal mucosa or their combination were included in the study. All patients provided a history of tobacco use or chewing betel nut (Table 1). None of these patients were smokers. Their OSMF was confirmed based on thorough clinical and histopathologic examinations. Routine hematologic investigations and radiography were performed for all patients. This study was approved by the local
Results
In the present series, complications such as flap loss, infection, flap necrosis, obstructive sialadenitis, and damage to facial nerve branches were not observed. However, intraoral hair growth and extraoral scar at the donor site were seen in all patients, 3 of whom subsequently underwent scar revision (Table 2). Histopathologically, the skin flap showed fewer adnexal structures, normal vascularity, and fibrocellular stroma (Fig 12). The buccal mucosa showed atrophic epithelium, muscle
Discussion
Various surgical modalities have been described in the literature. Results with skin grafting to cover raw areas have been disappointing because the incidence of shrinkage, contracture, and rejection of graft was found to be very high owing to poor oral conditions and subsequent recurrence of symptoms.15 Split-thickness skin grafts and bilateral temporalis muscle myotomy or coronoidectomy can be effective, but have the drawbacks of secondary contracture formation in the temporalis tendon and
