Abstract
INTRODUCTION: A prospective study was conducted to find out an effective alternative in the form of non-vascularized abdominal dermal fat graft (ADFG) and to compare its efficacy with the vascularised nasolabial flap (NLF) for the treatment of oral submucous fibrosis (OSMF). METHOD: Comparative study comprising of 30 patients with Grade 3 and 4A OSMF, randomly divided into 2 groups: Group A (ADFG) and Group B (NLF). They were evaluated for mouth opening (MO), graft uptake, time taken for mucosalization, pain, intercommissure distance (ICD), scar, duration of surgery (DOS), patient satisfaction and thickness of masseter muscle on ultrasonography. FINDINGS: At 6 months, MO improved by 22.4 and 36.2 mm in Group A and Group B, respectively. There was statistically significant difference (p < 0.05) seen for the values between the groups for all the parameters except for ICD and VAS score, which was statistically insignificant (p > 0.05). Intraoral hair growth, facial scar, orocutaneous fistula and commissure tear was seen in Group B. Complete necrosis of graft followed by recurrence was seen in three cases in Group A. CONCLUSION: NLF holds better as compared to ADFG in the management of OSMF. However, the cornerstone of success remains habit cessation and aggressive physiotherapy. The limitations of the study are small sample size and short duration of follow-up.
