Dermoid cyst

Diagnosis : Dermoid cyst typical location : along frontozygomatic suture line. Approach to management : Clinical exam: Anterior : smooth, well circumscribed, subcutaneous, painless mass, posterior aspect palpable. Posterior : if orbital extension present and posterior aspect not palpable, may cause globe displacement, visually significant ptosis and diplopia if grow to large size. CTscan : to rule out ntra orbital extension. (dumbbell dermoids) Treatment : Surgical excision in Toto to be done is removal is done with intact cyst wall without iatrogenic rupture which otherwise cause leakage of cystic contents into the orbit can cause significant inflammation and increase chances of recurrence. surgical approach : Anterior orbitotomy through superior eyelid crease incision sent the excised cyst for histo- pathology examination for confirmation.
