Oral Submucous Fibrosis Specialists in CVD, Delhi

What is Oral Submucous Fibrosis?

Oral submucous fibrosis is a chronic, progressive condition in which the tissue lining the mouth and throat becomes increasingly fibrous and stiff, gradually restricting the ability to open the mouth and move the tongue. It is strongly associated with the chewing of areca nut, betel quid, and related products, which trigger a persistent inflammatory response that leads to abnormal collagen deposition beneath the oral mucosa. The condition is considered a potentially malignant disorder, meaning it carries a notable risk of progressing to oral cancer over time, making early diagnosis and habit cessation particularly important. It is especially prevalent in South Asian populations where areca nut chewing is culturally common.

Causes of Oral Submucous Fibrosis

The primary cause is chronic chewing of areca nut, betel quid, gutka, or related products, which contain compounds that stimulate fibroblasts to produce excess collagen in the oral tissue over time. Nutritional deficiencies, particularly of iron and vitamins, along with genetic susceptibility, are believed to contribute to individual variation in disease severity. The condition typically develops after years of habitual use, though it can begin to appear even after relatively short periods of heavy exposure.

Symptoms of Oral Submucous Fibrosis

progressive difficulty opening the mouth fully, burning sensation in the mouth especially with spicy food, blanching or whitening of the oral mucosa, stiffness of the tongue and reduced tongue mobility, difficulty swallowing, dryness of the mouth, formation of palpable fibrous bands inside the cheeks, altered voice in advanced cases

Treatment & Types of Oral Submucous Fibrosis in CVD, Delhi

The most important step in management is complete and immediate cessation of areca nut and betel quid chewing, without which the condition will continue to progress regardless of other treatment. Medical management includes intralesional injections of corticosteroids or other agents to reduce fibrosis, along with nutritional supplementation and mouth-opening exercises to maintain jaw mobility. Surgical release of fibrous bands is used in advanced cases with severe restriction of mouth opening, and regular monitoring for early signs of oral cancer is essential given the condition's malignant potential.
