Collagen Membrane Over Buccal Fat Pad Versus Buccal Fat Pad in Management of Oral Submucous Fibrosis: A Comparative Prospective Study

Abstract

Objective

The objective of this study was to assess the effectiveness of collagen membrane as biological dressing over buccal fat pad (BFP) during crucial postoperative healing phase in the surgical management of oral submucous fibrosis (OSMF).

Study Design

The study comprised of 40 patients of OSMF of group IVa (Khanna and Andrade). Patients were randomly divided in two groups (20 patients in each group). Group I patients were treated using buccal fat pad only, whereas collagen membrane was used as a covering over harvested BFP in group II patients. Postoperative follow-up was done at 1 week, 3 weeks, 6 months and 1 year.

Result

Mean postoperative mouth opening achieved in both the groups was comparable at every follow-up visit. Infection was evident in four patients of group I at 1-week follow-up, whereas none of the group II patients developed infection. Pain score was lesser in group II patients as compared to group I. Relapse was seen in two patients in group I and one patient in group II. Time taken for epithelialization was 2–3 weeks in both the groups.

Conclusion

Although intraoperative time was increased in group II application of collagen membrane reduced infection when compared with group I. Also, the chances of damage to BFP are reduced during the hygiene maintenance at surgical site and jaw-opening exercise. Reduction in pain scores during postoperative period in group II patients was an additional advantage.
