Does Topical Application of Placental Extract Gel on Postoperative Fibrotomy Wound Improve Mouth Opening and Wound Healing in Patients With Oral Submucous Fibrosis?

PURPOSE: Placental extract has been used as a therapeutic agent with application in various fields of medicine. Placental extract is well known for its effects on wound healing with anti-inflammatory, antiplatelet, and angiogenic effects and is also a biogenic modulator. The present study evaluated the effect of placental extract on wound healing, mouth opening, and postoperative patient discomfort in patients with oral submucous fibrosis treated with fibrotomy with buccal fat pad coverage and coronoidectomy.

MATERIALS AND

METHODS

Ten subjects with oral submucous fibrosis who presented with mouth opening less than 20 mm were enrolled in the present prospective randomized controlled trial to assess the effects of placental extract on the fibrotomy wound covered with a pedicled buccal pad fat (5 patients allocated to the study group, group S and 5 to the control group, group C). The following criteria were used to analyze the postoperative effect of placental extract on fibrotomy wounds compared with that of the controls: subjective assessment of the wound, postoperative discomfort, and postoperative mouth opening assessed at 1, 2, and 4 weeks postoperatively.

RESULTS

The average difference in the preoperative and fourth week postoperative mouth opening for group C was 13.8 ± 2.68 mm and was 21.20 ± 2.77 mm in group S. The median calculated for group C was a 15.0-mm increase in mouth opening and was 20.0 mm in group S.

CONCLUSION

The results obtained with topical application of placental extract on fibrotomy wound healing and postoperative mouth opening were superior to those of the control group in whom placental extract was not used.
