Efficacy of nasolabial flap in reconstruction of fibrotomy defect in surgical management of oral submucous fibrosis: a prospective study.
OBJECTIVE
Various surgical modalities have been used in the surgical management of oral submucous fibrosis with variable results. This prospective study evaluates the efficacy of nasolabial flap in the reconstruction of fibrotomy defect in surgical treatment of oral submucous fibrosis in terms of functional and esthetic outcomes.


METHODS
In this prospective study, we treated 20 patients of oral submucous fibrosis surgically. The surgical protocol was consisting of bilateral fibrotomy, temporal myotomy, and coronoidotomy or coronoidectomy followed by reconstruction of fibrotomy defect with bilateral extended nasolabial flaps. All patients were prescribed with nutritional supplements and antioxidants. Vigorous mouth opening exercise was made compulsory for every patient. Preoperative and postoperative evaluation was done for interincisal mouth opening, function of mastication, and cosmetic results. Patient's regular follow-up was done for 2 years.


RESULTS
Postoperatively, we noted excellent increase in the interincisal mouth opening relieving trismus. Patient's ability to chew solid food was increased significantly. Extraoral scar was minimal and well accepted by all the patients. There was no morbidity of the donor site. There was no injury to the facial nerve in all cases. The only drawback was intraoral hair growth which went on reducing with mucosalization of the graft tissue.


CONCLUSIONS
Random pattern nasolabial flap is a very good option for intraoral reconstruction of fibrotomy defect in surgical treatment of oral submucous fibrosis with excellent functional and cosmetic results with minimal complications.
