Ann Abbasi Shaheed Hosp Karachi Med Dent Coll Jan ;21(3):171-6.

Objective: The aim of this study was to evaluate the clinical and anatomical application of buccal fat pad as an interpositional material in the surgical treatment of oral submucous fibrosis (OSMF) for improvement of mouth opening and its movements. Methods: OSMF has become a chronic, distressing condition of uncertain aetiology in Pakistan which rapidly involves the oral structures along with other parts of upper gastrointestinal tract. The study was conducted in Department of Oral & Maxillofacial Surgery, Ziauddin College of Dentistry, Ziauddin University, Karachi, from December 2013 till July 2015. We evaluated 50 diagnosed OSMF patients, with history of chewing areca/betal nut or other similar products, with burning sensation on having spicy ingredient, trismus 4-25mm with palpable fibrous bands on the buccal mucosa intraorally with rigidity and blanching were included in the study. Good clinical improvement with minimal morbidity by the use of buccal fat pad was noticed in patients with severe limited mouth opening along with regular and vigorous physiotherapy. Results: In 50 patients, the range of preoperative mouth opening was 4-24mm (14 ± 4.90), the intra operative mouth opening was 25-38mm (33.25 ± 4.17). The patients were discharged after 72 hours at this time mouth opening was 25-36mm (30.63 ± 3.82). Comparison of pre-operative with intra and post-operative mouth opening was statistically significant. Conclusion: This study has shown that use of interpositioning buccal fat pad flap improves the mouth opening and movement in OSMF patients.
