Basically there are two types of cysts – superficial ones that are formed adjacent to the orbital rim and the deep ones that are formed within the orbit. Over a thirteen year period forty patients underwent surgery to remove an orbital dermoid cyst. Cysts which became manifest after the age of three years were deeper and larger than most that were Diagnosis of Dermoid Cysts and Periocular Tumors. A physical exam usually reveals an orbital dermoid cyst. Ophthalmologists look for these signs: A rubbery growth above the eyebrow or next to the nose; Droopy eyelid; Inflammation; Deeper dermoids may need to be identified with other diagnostic tools like computed tomography.

CT for orbital dermoids reveals adjacent bone changes in 85% of cases, and a bony defect may be identified radiographically in dumbbell dermoids (5). On occasion, a deep orbital dermoid cyst can occupy much of the orbit (9). Some Op report reads (in part) PRE-OP DIAGNOSIS: Dermoid Cyst, Glabella INDICATIONS: Patient diagnosed with a glabellar dermoid cyst and evaluated with CT scan.

The commonest dermoid cysts are firm and smooth, mobile preseptal masses overlying the supero-temporal quadrant of the orbit and, less commonly, the supero-nasal quadrant. Many cysts have a variable periosteal attachment near the underlying fronto-zygomatic or fronto-ethmoidal sutures, but occasionally the dermoid will pass into or through defects in the neighbouring bone.

Case Report However, among the 250 children under 18 years, 46% were dermoid cysts. The survey found that more than 70% of orbital dermoid cysts were diagnosed before the age of 5 years.

Complete surgical excision is curative. [from NCI] Dermoid cysts are histologically defined as surface epithelium encapsulating an inner lumen. They are well described in the literature as discrete, single masses, either circumscribed or dumbbell-shaped, with or without a longstanding fistula. Chronic granulomatous inflammation is often a feature of … 2019-12-16 The preoperative diagnosis was cyst of the orbit, probably dermoid with some calcified ma terial.
