Oral submucous fibrosis (OSF) is a chronic, progressive, and potentially malignant condition of the oral cavity. It is characterized by the formation of fibrous bands in the submucosal tissue of the mouth, leading to stiffness and reduced mouth opening. It is most commonly seen in people of South Asian descent, particularly in India, and is associated with the chewing of betel quid, a mixture of betel nut, slaked lime, and other ingredients. OSF can lead to difficulty in eating, speaking, and breathing, and can also increase the risk of oral cancer. Treatment options include medications, surgery, and lifestyle modifications.

The main symptoms of Oral submucous fibrosis are:

1. Difficulty in opening the mouth (trismus)
2. Burning sensation in the mouth
3. Dryness of the mouth
4. Swelling of the cheeks
5. White patches on the inner lining of the cheeks
6. Difficulty in eating, speaking and swallowing

1. Topical medications: Corticosteroids, retinoids, and immunomodulators are used to reduce inflammation and reduce the risk of oral cancer.

2. Surgery: Surgery may be necessary to remove fibrotic tissue and restore normal mouth opening.

3. Laser therapy: Laser therapy can be used to reduce fibrosis and improve mouth opening.

4. Speech therapy: Speech therapy can help improve speech and swallowing difficulties caused by the condition.
