Abstract
PURPOSE: To evaluate the effectiveness of nasolabial flap (NLF), a buccal pad of fat flap (BFP), and platysma myocutaneous flap (PMF) for reconstruction following fibrotomy for individuals with oral submucous fibrosis (OSMF). MATERIAL AND METHOD: A retrospective study was conducted among patients diagnosed with grade III and IV OSMF in the Department of Oral and Maxillofacial Surgery at Sharad Pawar Dental College between January 2016 and August 2018. The essential patient information was obtained from the Medical Record Department (MRD) at Acharya Vinoba Bhave Rural Hospital (AVBRH), Datta Meghe Institute of Medical Sciences (DMIMS) Sawangi (Meghe) Wardha. The patients were categorized into three groups: the NLF, the BFP, and the PMF groups. Each group had 16 patients, and factors such as interincisal width, diminished burning sensation in the mouth, inter-commissure distance, and flap necrosis were compared pre- and post-operatively. Student's unpaired t-test and chi-square test were employed for statistical analysis. RESULT: Mean interincisal mouth-opening increased from pre-operative 4.79 to 41.42 mm post-operatively in the NLF group, BFP group from 6 to 39.42 mm and in the PMF group from 9.26 to 39.34 mm with p value=0.0001. NLF group showed complete and partial resolution of the burning sensation of the mouth at 93.75% and 6.25%, BFP at 62.25% and 32.75% while in PMF it was 68.5% and 31.25% respectively. One year postoperatively 3.28 mm increase in inter-commissure width was observed in the NLF group with a marginal increase in the PMF group and a negligible increase in the BFP group. 18.75% partial flap necrosis was seen in BFP, 18.75% in the PMF group, and 6.25% in the NFL group. CONCLUSION: All the flaps are efficacious in treating OSMF, however, NLF stands ahead with its higher reliability owing to its excellent blood supply.
