Abstract

Oral submucous fibrosis(OSF) is an insidious chronic disease affecting the mucosa of the oral cavity and occasionally extending into the pharynx and esophagus. It is associated with a genetic predisposition and alterations, infectious and viral agents, carcinogens, nutritional and immunological factors. The etiology is obscure but it is correlated with a hypersensitivity to capsaicin, secondary to chronic iron and or vitamin B complex deficiencies or exposure to cashew kernel oil. We report a patient who had a mouth opening limitation caused by a fall when he was 8 years old despite several treatments at other hospitals. Excellent results were obtained by releasing the scar tissue using a standard split-thickness skin graft(STSG) which obtained from the thigh. It is important to recognize as a precancerous condition and to inspect the excision site and the remaining oral mucosa during long-term follow-up on a regular basis.
