Dual Drug Therapy Versus Single Drug Therapy in Prevention of Pinna Keloid Recurrence.

Keloids are fibroproliferative disorders caused due to injury to skin. The recurrence rate has been found to be as high as 100% even after surgical excision. The high recurrence rate has led to the need for various adjuvant therapies as a single approach alone has not been found to be efficient in preventing recurrence. This attributes to the need for a multimodal approach. Steroids are found to be useful in preventing recurrence. To evaluate the efficacy of the combination of hyaluronidase with corticosteroid injection compared to corticosteroid injection alone in the prevention of recurrence of keloid after surgical excision. This randomized controlled study was conducted in the Department of Otorhinolaryngology among 50 patients with ear keloids who underwent surgical excision. Patients were divided into two groups. One group was given Triamcinolone injection alone and the other was given Triamcinolone with Hyaluronidase on postoperative weeks 1, 2, and 3. Patients were followed up for 6 months and recurrence was noted and compared. Statistical analysis was done and the results were considered significant with a p-value of less than 0.05. Of the total 50 patients, there were a total of eight male and 39 female patients. In a single therapy group, recurrence was noted in one patient after 3 months and in three more patients after 6 months. In the group with combination therapy, there was no recurrence after 3 months but three patients had recurrence after 6 months. Triamcinolone and hyaluronidase injection protected from recurrence for about 3 to 5 months after which patients had recurrence. Further studies are recommended with prolonged duration of hyaluronidase injection.
