Intralesional Electrocoagulation With Insulated Microneedle for the Treatment of Periorbital Syringomas: A Retrospective Analysis

BACKGROUND: Conventional treatment options for periorbital syringomas are often unsatisfactory because of inevitable surface damage from the procedure and frequent recurrence rate of the tumors. OBJECTIVES: The authors sought to ascertain the efficacy and safety of intralesional electrosurgery utilizing a monopolar radiofrequency device with a single insulated microneedle for the treatment of periorbital syringomas. METHODS: A retrospective analysis was performed employing data from medical records, routine questionnaires, and clinical photographs of 55 patients with periorbital syringoma who underwent intralesional electrosurgery. RESULTS: Approximately one-half of the patients (50.9%) experienced marked resolution after 1 treatment. The lesion clearance rate increased and lesion severity decreased each time the treatment was repeated. No persistent therapy-related adverse event was found except transient erythema or crusting. CONCLUSIONS: Intralesional electrosurgery with insulated microneedle is an effective and safe treatment option for periorbital syringomas.
