Abstract
PURPOSE: To report the incidence, clinical findings, and surgical outcomes of periocular dermoid cysts diagnosed among children over a 20-year period. METHODS: All patients ≤5 years of age, who were diagnosed with a periocular dermoid cyst in Olmsted County, Minnesota from 1986 to 2005 were reviewed to determine the population incidence, clinical presentation, and management outcomes. RESULTS: A total of 54 children were diagnosed with a periocular dermoid cyst during the 20-year period, yielding a birth incidence of 1 in 638 live births. The mean age at diagnosis was 12 months (range, 1 month-60 months) and 29 (53.7%) were female. A total of 44 cysts (81.5%) occurred in the superotemporal orbital rim, 6 (11.1%) in the superonasal orbital rim, 3 (5.6%) in other periocular areas, and one (1.9%) within the orbit. A total of 34 (63%) children had an ophthalmic exam, all without amblyopia or other ocular sequelae. A total of 48 (88.9%) patients underwent surgical excision with 5 (10.4%) having documented intra-operative cyst rupture, none of whom had post-operative complications. Two (4.2%) other patients were, however, noted to have lesion recurrence following surgical intervention. CONCLUSIONS: Periocular dermoid cysts occur in approximately 1 in 650 live births and most commonly occur in the superotemporal region of children aged 1 year or less. Ocular sequelae are rare and surgical excision often yields excellent results.
