Eun, Sung, Byung, Kyoo, and Hong: The Effects of Intralesional Steroid Injection for Chalazion According to the Concentrations of Triamcinolone Acetonide

Abstract

Purpose

To compare the efficacy of an intralesional steroid injection in the treatment of chalazion according to triamcinolone acetonide (TA) concentrations.

Methods

A total of 108 patients with 120 chalazia received an intralesional injection of TA. Patients were divided into 3 groups according to the concentrations of TA: 5 mg/ml, 10 mg/ml, and 40 mg/ml. A regular follow-up was performed and the size of lesion and recurrence were evaluated.

Results

Success was defined as a minimum of 80% decrease in size with no recurrence. The success rate was 78.1% in the 5 mg/ml group, 76.2% in the 10 mg/ml group, and 78.4% in the 40 mg/ml group. These results were not statistically significant (p = 0.999, Fisher's exact test). Yellow deposits developed in 4 out of 37 lesions in the 40mg/ml group, and in 1 out of 42 lesions in the 10 mg/ml group. Skin depigmentation was observed in 1 case in the 5 mg/ml group.

Conclusions

Intralesional TA injection is an effective treatment for chalazion. There is no significant difference in success rates according to the concentrations of TA. However, caution is advised in cases of high injection concentrations of TA to prevent yellow deposits.
