Abstract
Objective
To evaluate the functional efficacy of two different grafting techniques following the fibrotomy among subjects with oral submucous fibrosis (OSMF).
Design
Forty consecutively treated OSMF subjects between 20 and 40 years who had grades 3 and 4a OSMF and mouth opening < 15 mm were included in the present study. All the subjects were randomly divided into two groups. In Group I, all the subjects received a buccal pad of fat sandwiched with a nasolabial flap following fibrotomy. In contrast, Group II subjects received a buccal pad of fat combined with a collagen graft. The effect of two different surgical protocols on mouth opening was evaluated clinically before the surgery (T0) and 1 month (T1), 6 months (T2), and 12 months (T3) after the surgery.
Results
In Group I subjects, the mouth opening increased significantly (P < 0.001) from 10.90 ± 1.971 mm at T0 to 34.25 ± 3.127 mm at T1, but reduced marginally to 32.15 ± 3.422 mm at T2, and 31.30 ± 3.358 mm at T3. In Group II, the mouth opening increased significantly (P < 0.001) from 10.85 ± 1.725 mm at T0 to 28.90 ± 3.059 mm, 29.10 ± 2.808 mm, and 28.20 ± 2.285 mm at T1, T2, and T3, respectively. At the end of 12 months of follow-up, the mean value improvement in the mouth opening (T0–T3) was 20.4 ± 3.5 mm and 17.3 ± 2.9 mm in Groups I and II, respectively, and the difference was statistically significant (P = 0.006).
Conclusion
The buccal pad of fat sandwiched with a nasolabial flap for the reconstruction following fibrotomy had a slightly better beneficial effect on the postoperative mouth opening among OSMF subjects.
