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.
