Abstract

Dermoid cyst, a developmental benign choristoma, is the most common orbital tumor of childhood, arising from ectodermal sequestration along the lines of embryonic fusion of mesodermal processes, lined by keratinized stratified squamous epithelium & expanding slowly due to constant desquamation & dermal glandular elements.

Approximately 80% are found in the head region i.e. 3-9% all orbital masses. Classified as juxta-sutural, sutural or soft tissue cysts; superficial or deep; intraosseous & extraosseous, & intra orbital & extraorbital, respectively.

These smooth, painless, mobile masses mostly present at the fronto-zygomatic suture with proptosis, ptosis, diplopia, depending on depth & extent. Surgical technique is adopted based on site, extent, age & aesthetic needs, presence of inflammation & possibility of spontaneous rupture.

The embryological origin, various sites, clinical features, surgical & minimally invasive techniques for management of dermoid cysts shall be displayed here.
