Dermoid cysts are the most common benign orbital lesions in pediatric population. Depending on the site of origin they can be sutural, anterior orbital, deep orbital, trans-orbital, intraosseous or conjunctival. Complete surgical excision is the treatment of choice. Inflammation, recurrence and fistula can complicate capsular breach and incomplete excision. Dermoids pose a surgical challenge due to their periosteal or sutural attachment, bony erosion, fistula formation and risk of intra-operative rupture. This video demonstrates step-by-step approach to excision of an external angular dermoid.
The technique shows the importance of identifying the anatomical landmarks and emphasizes on complete excision of an intact dermoid cyst. Identification of sutural attachment, periosteal tether and trans-orbital extension by imaging and attention to details during dermoid excision surgery gives gratifying outcome. This video demonstrates a meticulous technique of surgical excision.
