Abstract

Dermoid cysts are among the most common periorbital and orbital tumors presenting in childhood. Several studies have shown that dermoid cysts may deform adjacent bones; however, few studies have followed the course of bone regeneration after the excision of a cyst. We report a case of a 29-month-old female infant who presented with a palpable mass over her right lateral eyebrow. Ultrasonography findings suggested a dermoid cyst, and computed tomography revealed a 2.1-cm round bony defect in the right zygoma. After surgical excision of the dermoid cyst, we successfully applied fibrin sealant to eliminate the dead space. Pathological findings showed nodular lesions with flat cystic walls containing lamellated keratin and sebaceous glands, supporting the diagnosis of dermoid cyst. At 6 months postoperatively, a follow-up computed tomography scan confirmed complete recovery of the bone defect in the right zygoma.
