To evaluate the effectiveness of intralesional triamcinolone acetonide injection, and incision and curettage for primary chalazia.

In order to compare the effectiveness of treatment modality, 103 patients who were diagnosed with primary chalazia were divided into 2 groups. The patients in group A underwent intralesional triamcinolone acetonide injection and the patients in group B underwent incision and curettage. The patients were followed up 1 week and 3 weeks after the procedures to identify the regression of the lesion and the procedure complications. A decision regarding success or failure was made at 3 and 6 weeks after the treatment. Successful treatment was defined as the infallibility in the functional and esthetic aspects as well as the size of regressed lesion.

This study included 82 out of 103 patients, who satisfied the inclusion criteria. Forty-four patients underwent intralesional triamcinolone acetonide injection and the remaining 38 patients underwent incision and curettage. The success rate of the initial treatment, which was identified 3 weeks after the procedure, was 81.8% in group A and 86.8% in group B. The cumulative success rate of treatment after 6 weeks was 86.8% in group A and 92.1% in group B. No complications were observed with both treatment modalities.

Intralesional triamcinolone acetonide injection is as effective and safe as incision and curettage for the treatment of primary chalazia.
