Oral Submucous Fibrosis: A Review of the Current Concepts in Management.

Abstract

Oral submucous fibrosis (OSMF) is a precancerous disorder of the submucosa that causes inflammation and progressive fibrosis, leading to pronounced stiffness and trismus. Chewing betel nuts is a significant risk factor for OSMF in India. Arecoline from betel nuts and copper, which causes fibroblast dysfunction and the development of fibrotic bands, are the main components of betel quid. OSMF is distinguished by fibrosis in the submucosal region, which affects the majority of the oral cavity and results in advanced lockjaw due to rigidity in the lips, pharynx, cheeks, and upper third of the oesophageal canal, which progresses to dysphagia. The prevalence of OSMF is rising, particularly among younger generations, as more commercially available areca nut products like gutka (chewing tobacco) and others are being introduced. The severity of OSMF develops as the practice continues and is permanent. It also persists even after chewing has been stopped. The hallmark of oral submucous fibrosis (OSF) is abnormal collagen deposition. It is a precancerous condition and progresses to malignant tumours. Symptoms include ulcers, xerostomia, submucous fibrosis, burning sensation, and a reduction in mouth opening. Each of these drastically reduces the patient's quality of life. In the past, many treatment modalities have been tried but none of them has resulted in a cure for the disease. The primary focus of the treatment is to reduce the signs and symptoms so that the patient can have a better quality of life. Along with principles, conservative, medical, and surgical management issues have also been covered.
