Background
Oral sub mucous fibrosis is a rare chronic, progressive, pre malignant collagen disorder of oral mucosa in people of Asian descent characterized by trismus, blanching and stiffness of mucosa, burning sensation in mouth and hypomobility of soft palate and tongue with loss of gustatory sensation. Betel nut chewing is the most common etiological agent. Surgery remains the main stay in severe cases and aims at release of fibrotic bands and resurfacing the raw areas with different options. Reconstruction can be done by using nasolabial flap or radial free forearm flap. The purpose of this study was to compare the mouth opening after the reconstruction with either nasolabial flap or radial free forearm flap.
Methods
This study was carried out on fifty (50) patients with oral sub mucous fibrosis. Twenty five (25) of these were reconstructed by nasolabial flap and twenty five (25) were reconstructed by radial free forearm flap. At different intervals of their post-operative visits, they were evaluated for the interincisal distance and the difference between the two groups was assessed.
Results
Average increase in interincisal distance was greater in patients reconstructed with radial free forearm flap compared with patient reconstructed by nasolabial flap i.e. 18.96 mm and 15.16 mm respectively with ‘P’ value > 0.05.
Conclusion
Based on this study radial forearm free flap is a superior method compared to transposition of nasolabial flap to cover the surgical wound of oral submucous fibrosis.
