Conservative Management Strategies for Oral Submucous Fibrosis: A Comprehensive Review

Oral submucous fibrosis (OSMF) is a chronic, progressive, and potentially malignant disorder of the oral cavity characterized by submucosal fibrosis, restricted mouth opening, and burning sensation. Early diagnosis and intervention are essential to prevent functional impairment and reduce the risk of malignant transformation. This review aims to provide a comprehensive overview of the various nonsurgical treatment modalities available for the management of OSMF and to evaluate their effectiveness in improving clinical outcomes. A narrative review of the literature was conducted, focusing on conservative treatment approaches including habit cessation, nutritional supplementation, physiotherapy, microwave diathermy, and pharmacological therapies such as corticosteroids, hyaluronidase, collagenase, placental extracts, interferon-gamma, pentoxifylline, platelet-rich plasma (PRP), and omega-3 fatty acids. Available clinical studies, case series, and trials were analyzed with respect to improvements in mouth opening, burning sensation, and overall patient satisfaction. The findings indicate that habit cessation and nutritional support are the cornerstones of management, particularly in the early stages of the disease. Physiotherapy and microwave diathermy contribute to functional improvement, while intralesional pharmacological agents, used alone or in combination, demonstrate significant benefits in reducing symptoms and enhancing mouth opening. Emerging therapies such as PRP and omega-3 fatty acids have shown promising results with minimal adverse effects. Overall, nonsurgical therapies are effective in managing early and moderate stages of OSMF by providing symptomatic relief and improving oral function. However, advanced cases often require surgical intervention. Early diagnosis, patient compliance, and a multimodal treatment approach remain critical for achieving optimal therapeutic outcomes.
