Abstract
A chronic, persistent, possibly cancerous condition that mostly affects the oral cavity is called oral submucous fibrosis (OSMF) and causes severe functional impairment. Due to its complex nature, OSMF requires a comprehensive strategy that includes both surgical and medication therapies. Multidisciplinary treatment was started, which included a complete stoppage of habit, dental hygiene precautions, dietary counselling, surgical intervention, supportive medicinal therapy, and physiotherapy. Following surgery and adjunct therapy, the patient's mouth opening and functional results were improved. The patient is kept for regular follow-up to assess the recurrence of fibrosis or any incidence of malignant transformation. This case emphasizes the difficulties in treating advanced OSMF and emphasizes how crucial it is to improve patient outcomes by early detection, stopping betel nut chewing, and thorough multidisciplinary care.
