Minimal Invasive Excision of Intraorbital Dermoid Cyst

Dermoid cysts are benign tumors that represent the simplest form of teratoma (1). Approximately 7% of dermoid cysts affect the head and neck region, and within this region, they are commonly found along the orbital walls(2). Orbital dermoid cysts occur most commonly along the lateral aspect of the orbit, in approximately 69% of cases. Intraorbital location is relatively rare for these lesions. It is known that the treatment of periorbital dermoid cysts is easier than intraorbital cysts which require more aggressive interventions (3).The choice of surgical approach for the resection of orbital cyst is determined by the cyst position in the orbital space as a rule and the best choice is the most direct approach to orbital tumor. Lateral orbitotomy as the extracranial orbital approach is favorable for radical resection of the tumor, which growth is limited to the anterior, lateral and superolateral orbital segment. (1, 2, 3). We hereby report three cases of intraorbital dermoid cyst, which were totally excised by minimally invasive surgery. MINIMAL INVASIVE EXCISION OF INTRAORBITAL DERMOID CYST
