Treatment of an orbital pseudomeningocele through an eyelid incision
Pseudomeningoceles (PMs) occur from extravasation of cerebrospinal fluid (CSF) into soft tissue secondary to a dural tear.1–3 Unlike a true meningocele, which is lined by arachnoid tissue, PMs are associated with the formation of a fibrous capsule.2 Although PMs can form due to surgical insults to the dural covering of the brain or spine, they can also occur secondary to trauma or congenital abnormalities.1,2 Clinical symptoms usually arise when there is mass effect on the surrounding structures.Sudden-onset diplopia after LeFort I advancement
A LeFort I osteotomy with horizontal advancement is a commonly used procedure to correct both class II and class III malocclusions, as well as dentofacial asymmetries.1 Complications associated with this procedure are variable but can include malposition of the maxilla, abscess formation, epistaxis, unilateral third nerve palsy, and Adie's tonic pupil.1 We report a rare case of carotid-cavernous fistula and pseudoaneurysm formation after LeFort I advancement in a 24-year-old male with a unilateral left paramedian cleft palate with class III malocclusion and maxillary hypoplasia.
