Introduction: Oral sub mucous fibrosis is a common potentially malignant condition affecting around 8.06 % of the population in India. These patients usually complain of limited mouth opening and a burning sensation while eating. Normally, such patients are managed surgically, adopting the Borle et al. protocol. These protocols usually provide satisfactory results in the majority of patients. Some patients, however, may require adjuvant procedures. This poster highlights masseter myotomy as an adjuvant procedure for the management of OSMF.
Case report: A 31-year-old patient reported with a chief complaint of reduced mouth opening for the previous 2 years. Examination revealed mouth opening of 12mm and type 4 OSMF. This necessitated surgical management comprised of bilateral fibrotomy and coronoidectomy. Despite this, the mouth opening was 30mm. Therefore, masseter myotomy was performed; mouth opening of 34mm was achieved, following which the fibrotomy defect was resurfaced with a bi-winged nasolabial flap.
Results: Even after 7 months of post-operative follow up, the patient is exhibiting a satisfactory mouth opening of 36mm.
Conclusion: Masseter myotomy is a fair adjuvant procedure to treat severe cases of OSMF.
