Aim: The aim of this study was to compare the efficacy of nasolabial flap, split thickness skin graft and collagen sheet in increasing postoperative mouth opening as a reconstructive material in surgical management of Oral Submucous Fibrosis (OSMF). Materials and Methods: 15 patients were included in this prospective cohort study and were randomly divided into 3 groups of 5 patients, based on type of graft material used for reconstruction. Group 1 patients received nasolabial flap, Group 2 patients received split thickness skin grafts and Group 3 patients received collagen sheet after resection of fibrous bands. Histologically proven cases of OSMF with mouth opening less than 25 mm were included in the study. Patients were evaluated at regular intervals and mouth opening was documented preoperatively, intraoperatively, and at 1 and 3 months of follow-up. Results: In all three groups, mouth opening differed substantially at all periods of follow-up from preoperative values. At 1 month follow up mean mouth opening increased to 28.4 mm in Group 1, 26.2 mm in Group 2 and 25.0 mm in Group 3. At the end of 3 months of follow up mean increase in mouth opening was greater in Group 1 (29.6 mm) in comparison to Group 2 (20.2 mm) and Group 3 (19.2 mm). Conclusion: No statistically significant difference in mouth opening was observed in three groups. Nasolabial flaps, split thickness skin grafts and collagen sheet are good options for reconstruction of defects created by resection of fibrous bands in patients with OSMF. |
