Oral submucous fibrosis--treatment with hyalase.

Oral Submucous Fibrosis (OSMF) is a disease of unknown etiology. A total of 96 patients with Oral Submucous Fibrosis have received four regimens of treatment--local dexamethasone, local hyaluronidase, local combination of dexamethasone and hyaluronidase, and local placental extract. The patients were followed up for a period varying from 3 months to 2 years. The group of patients receiving hyaluronidase alone showed quicker improvement in symptoms although its combination with dexamethasone gave somewhat better longer-term results. A new regimen for the treatment of submucous fibrosis is recommended.
