Surgical defect coverage in oral submucous fibrosis patients with single-stage extended nasolabial flap.
OBJECTIVE
Long standing oral submucous fibrosis (OSMF) is associated with involvement of the oral submucosa and the muscles of mastication leading to difficulty in mouth opening. Various surgical modalities are mentioned for release but each has its own limitations. The aim of the study was to evaluate the postoperative mouth opening in patients of OSMF after excision of fibrous bands followed by coronoidotomy and surgical defect coverage by extended nasolabial flap.


METHODS
We evaluated the use of extended nasolabial flaps and coronoidectomy in the management of 11 randomly selected patients with histologically confirmed oral submucous fibrosis. They all had interincisal opening of less than 25 mm and were treated by bilateral release of fibrous bands, coronoidectomy or coronoidotomy, and extended grafting with a nasolabial flap.


RESULTS
Their interincisal opening improved significantly from a mean of 8.68±7 mm to a mean of 36.75±4.05 mm at 6-month follow-up.


CONCLUSIONS
The procedure was effective in the management of patients with oral submucous fibrosis, the main disadvantage being the extraoral scars.
