Objectives: The objective of the study was to evaluate the results of nasolabial/extended nasolabial flaps as a modality for treatment of oral submucous fibrosis.
Materials and Methods: Eleven patients of Stage III or IVa maximum interincisal opening were selected to be operated. Nasolabial/extended nasolabial flaps were done for both the sides. All of the flaps were done in a single stage and were inferiorly based. A similar flap harvest/surgical technique was utilized for all the cases.
Results: The preoperative mouth opening ranged from 5 to 16 mm, with a mean of 10.09 mm. At 6 months the mouth opening ranged from 29 to 39 mm. Some of the complications encountered were poor scar, wisdom tooth traumatising the flap, decreased mouth opening due to non compliance and too much bulk. All of theses were managed satisfactorily.
Conclusion: The nasolabial flap is a very reliable flap to restore the function of oral cavity. Important adjuvant measures are habit cessation, lifestyle changes, and aggressive physiotherapy.
