[Efficacy for combined injection of salvizanolic acid B with triamcinolone acetonide on the treatment of the soft palate with oral submucous fibrosis].

Abstract

To evaluate therapeutic effect of combined injection of salvizanolic acid B with triamcinolone acetonide on the treatment of the soft palate with oral submucous fibrosis.
 Methods: Salvizanolic acid B combined with triamcinolone acetonide was consecutively applied once a week for 30 weeks for 33 patients with middle and later periods of oral submucous fibrosis. The response rate of color change in the soft palate and the increase of capillary vessels (determined by degree I-IV visual analog scale) were evaluated at the 12th, 24th, and 36th months after 30 weeks treatment.
 Results: Thirty-three patients were fulfilled the study without obvious adverse reactions and they were followed up for 24 months, while 31 patients were followed up for 36 months. The color change in the soft palatal mucus and the increase of capillary vessels at the 36th month follow-up after treatment were significantly better than those at the 12th month (P=0.004).
 Conclusion: Combined injection of salvizanolic acid B with triamcinolone acetonide in the treatment of the soft palate with oral submucous fibrosis is effective.
