Objectives:
The aim of this study is to confirm the effect of adjuvant intralesional triamcinolone acetonide injections (TRIAM) for the treatment of an infected preauricular sinus (PAS).
Methods:
The medical charts of 103 patients diagnosed with PAS from March 2013 to December 2015 were reviewed and documented. The mean duration of treatment and postoperative follow-up period were compared between patients who received TRIAM and patients who received conventional treatment.
Results:
Fifteen patients received TRIAM. The mean duration of treatment was 12.5±11.0days in patients treated with TRIAM, which was significantly shorter than patients without TRIAM (25.5±25.7days, p=0.010). In addition, the percentage of patients experiencing early recovery (within 10days) was 4.15 times higher with TRIAM (95% confidence interval: 1.07-16.13, p=0.040). The mean postoperative follow-up period revealed a similar tendency; patients treated with TRIAM required a shorter follow-up period (8±2.6days) than patients not treated with TRIAM (13.5±7.4days). However, this difference was not significant (p=0.242).
Conclusion:
Although the sample was small, patients with PAS infections who were treated with TRIAM as an adjuvant therapy required a significantly shorter treatment duration than patients receiving conventional treatment alone. This finding suggests a beneficial effect of TRIAM for the short-term control of PAS infections. Clinicians should consider TRIAM as an adjuvant treatment option.
