Orbital and periorbital dermoid cysts: Comparison of clinical features and management outcomes in children and adults.

To compare differences in clinical presentation and management outcomes of orbital and periorbital dermoid cysts in children and adults. A retrospective interventional comparative consecutive case series. 203 patients in (148 children [Age ⩽18 years] and 55 adults [Age >18 years]), who underwent excision biopsy for orbital/periorbital dermoid cyst were included. Outcome measures included the differences in demography, clinical presentations, radiological features, surgical outcomes and histopathology of cysts between children and adults with dermoid cysts. The mean age noted at excision was 15 years in this cohort of 148 children and 55 adults. Commonest clinical finding observed was a subcutaneous painless mass (94%) and external angular dermoids were commonest in both groups 1 and 2 (51% and 56%).

Secondary visual, orbital, radiologic changes and intra-operative rupture of dermoid cyst are more common in adults compared to children.
