About Kayakriti and Your Surgeon
A short walk-through of our Lucknow clinic, plus a brief introduction from Dr. Amit Agarwal.
Oral Submucous Fibrosis is a complex condition characterized by the significant stiffening of the mucosal lining inside the mouth, leading to a progressive inability to open the mouth. This condition is considered precancerous and is primarily caused by the consumption of tobacco.
OSMF typically begins in the posterior part of the mouth’s interior and spreads outward, potentially affecting the entire oral cavity. Since it is a precancerous condition, there is a risk of it transforming into oral cancer . OSMF develops in stages:
Inflammation: The condition starts with inflammation of the oral mucosa.
Fibrosis: This is followed by the development of fibrous tissue and blanching of the oral mucosa.
Trismus: In advanced stages, patients experience restricted mouth opening, a condition known as trismus, due to the formation of fibrous bands.
Causes and Prevention
The primary cause of OSMF is the use of tobacco, whether in the form of chewable tobacco or through smoking. To prevent OSMF, the following steps are recommended:
Health education and awareness regarding the cessation of tobacco use.
Regular oral cancer screening by healthcare providers.
Consequences of OSMF
OSMF can lead to various oral health issues, including:
Poor oral hygiene.
Impaired speech due to restricted soft palate movement.
Difficulty in chewing and swallowing food.
Thickened lips.
Loss of flexibility in the cheeks.
Burning sensation of the oral mucosa.
Symptoms of OSMF
Dryness of the mouth
Decreased mouth opening
Reduced protrusion of the tongue
Recurrent ulceration
Stiff lips if fibrosis extends to the lips
Burning sensation of the oral mucosa
Characteristic Features of OSMF
Dental staining due to tobacco use
Blanching of the oral mucosa
Intra-oral redness
Reduced mouth opening
Grades of OSMF
OSMF is categorized into four grades based on severity:
Grade I: Burning sensation is present, but no fibrotic bands are observed.
Grade II: Burning sensation is present, and fibrous bands are visible. Mouth opening is between 26 to 35mm.
Grade III: Blanching of the oral mucosa is evident, and the tongue is involved. Mouth opening is between 6 to 25mm.
Grade IV: Fibrosis extends to the lips, and the mouth opening is less than 5mm.
Diagnosis at Kayakriti
At Kayakriti, OSMF is diagnosed based on specific features:
Blanching of oral mucosa, which may be localized or diffuse.
The tough and leathery texture of the oral mucosa.
Palpable fibrous bands.
Treatment of OSMF
The treatment of OSMF depends on the stage at which it is detected:
Early Stage (Grade I & II): Medical management is recommended, including the use of anti-inflammatory, oxygen radical scavenging, and antifibrotic drugs. Corticosteroids may be used during the early inflammatory phase. Other treatments such as hyaluronidase, chymotrypsin, collagenase, pentoxifylline, iron, and lycopene have limited roles.
Advanced Stage (Grade III & IV): Surgical intervention is necessary. This may involve excising fibrous bands and using grafts or flaps to maintain increased mouth opening.
Surgical Procedures for OSMF
Various surgical procedures are performed based on the extent and severity of OSMF:
Primary Excision: Fibrous bands in the buccal mucosa, tongue, and soft palate are excised. This procedure is effective for less severe cases.
Conservative Adjunctive Surgical Procedures: These include detaching the coronoid process from muscle attachment (coronoid-ostomy) or intentionally cutting the coronoid process (coronoid-ectomy) when adequate mouth opening cannot be achieved with excision alone.
Interposition Grafts & Flaps: Grafts or flaps are used to maintain mouth opening after surgical excision of fibrous bands. These can include skin grafting, local flaps, and distant flaps.
Post-Operative Care
Post-surgery care is crucial and includes extensive physiotherapy to maintain mouth opening achieved through surgery. Cessation of tobacco use is essential to prevent relapse. Prosthetic devices may also be used to guide healing tissues and stabilize grafts.
Physiotherapy with mouth openers, dietary supplementation, and regular monitoring of mouth opening are key components of post-operative care.
Consulting with Dr. Amit Agarwal at Kayakriti is essential to determine the most suitable treatment plan based on the specific stage and condition of OSMF.
