Oral Submucous Fibrosis (OSMF)

What is Oral Submucous Fibrosis?

Oral Submucous Fibrosis (OSMF) is a chronic, progressive, precancerous condition of the mouth characterized by stiffness of the oral mucosa due to abnormal collagen deposition. It is strongly associated with the use of areca nut (supari), betel quid, and tobacco chewing. Early diagnosis and management are vital to prevent malignant transformation into oral cancer.

Common Symptoms

Burning sensation in the mouth, especially with spicy food
Stiffness and reduced mouth opening (trismus)

White or pale patches inside cheeks and oral mucosa
Ulcerations or recurrent mouth sores

Difficulty eating, swallowing, or speaking
Progressive tightening of oral mucosa

Treatment Options

Habit Cessation

Complete cessation of areca nut, betel quid, and tobacco is the most important step in management.

Medical Management

Topical steroids, antioxidants, and vitamin supplements help reduce burning and inflammation.

Surgical & Advanced Therapy

Severe cases may require surgical release of fibrous bands, physiotherapy, or regenerative therapies.

Is OSMF curable?

OSMF is a chronic condition. With early intervention, symptoms can be managed and progression controlled, but advanced cases may require surgery.
