A Clinicopathological Study of OSMF to Evaluate the Response After Treatment with Intralesional Steroid Versus Intralesional Steroid Plus Hyaluronidase

Oral submucous fibrosis (OSMF) is a chronic debilitating and a well-recognized potentially malignant condition of the oral cavity, sometimes involving oropharynx associated with trismus and burning sensation. Apart from medical management and counselling, local injection of hyaluronidase mixed with triamcinolone acetonide has been used at our centre for the last 20 years with satisfactory clinical results and without any significant side effects. The problem with the treatment was that the doses and duration of treatment has not been standardized. Therefore, in this study, authors aim to evaluate and compare the efficacy of Triamcinolone alone versus Triamcinolone acetonide plus Hyaluronidase at weekly interval and improvement in Clinical and Histopathological staging of disease after 6 weeks of treatment. This study was conducted in Department of Otorhinolaryngology & Head Neck Surgery, with a total sample of 80 participants divided into two Groups, group A received Inj. Triamcinolone acetonide and group B received Inj. Triamcinolone Acetonide and Hyaluronidase 1500 IU at weekly interval. Pre-treatment and post-treatment clinical and histopathological profile of the patients were recorded and analyzed using SPSS 16 software. According to pre-treatment status, the proportion of clinical grades I, II and III were found in proportion 12.5%, 18.8% and 15.0% respectively. No significant difference was found in proportion of various grades between the groups (p = 0.388). At post treatment, the grading was reduced with changed proportion of grades I, II and III cases as 33.8%, 41.3% and 7.5% respectively. There was no significant difference in proportion of various grades between the groups (p = 0.681). Further, the intragroup comparison showed significant improvement Pre to post in group A (p = 0.002), Group B (p < 0.001) and overall, as well (p < 0.001). The inj. Triamcinolone acetonide and Inj. Hyaluronidase showed a better improvement on post treatment histopathological grading although the difference between the two groups was not significant statistically.
