Submucous fibrosis is a debilitating chronic condition marked by progressive fibrosis of the oral cavity and throat, particularly the buccal mucosa, resulting in trismus. The disease has a significant prevalence in the Indian subcontinent, with the highest incidence in South India due to a variety of harmful practises. Surgical surgery is sometimes necessary in the treatment of oral submucous fibrosis, despite the many medicinal options available. Following the removal of fibrous bands, various flaps have been employed to restore surgical defects. Because of its superior vascular supply and low donor site morbidity, the buccal fat pad remains the most versatile.
