Aim This study was conducted to assess the efficacy of buccal fat pad and collagen in the surgical management of oral submucous fibrosis.
Materials and methods This camparative study was conducted on 20 patients with reduced mouth opening due to oral submucous fibrosis (Khanna and Andrade Classification Grade 3 and 4 a), randomly divided into 2 groups. In one group, the buccal fat pad was harvested and in another group, only wet bovine collagen sheet was applied as surgical dressing in the intra-oral wound after fiberotomy.
Results Both the dressings resulted in the achievement of nearly normal mouth opening with insignificant differences in the proportion of relapse. Buccal fat pad as an autogenous graft has the advantage of better vascular supply, minimum donor site morbidity, better strength and resilience during the healing phase. Xenogeneic collagen has better availability, no donor site morbidity, ease of application and better coverage of the surgical wound.
Conclusion Considering post-operative healing and surgical convenience, use of collagen sheet is a superior method to the transposition of the buccal fat pad.
