title: Frontal sinus mucocoele: a rare cause of ptosis.
abstract: A 73-year-old man, with no medical history of note, presented with a 4-week history of an isolated left-sided ptosis and associated periorbital and retro-orbital discomfort. His pupils were spared, his eye movements were not restricted and he was not proptosed. A prompt CT orbits and head scan revealed a large left frontal sinus mucocoele that had eroded into the left orbit. The patient had successful endoscopic sinus surgery under the ear, nose and throat team and 1 month later was seen in ophthalmology clinic. His ptosis and discomfort had fully resolved and he had no neurological sequelae from the surgery.
