Animate foreign bodies in the ear are frequent occurrences in otology practice. Such foreign bodies may lead to hazardous complications.
This paper describes a retrospective study of six patients with a recent history of an insect in the ear who presented with various complications following intervention received elsewhere.
An insect was retrieved from the external auditory canal in four cases and from the antrum in two cases. The patients presented with progressive otological complications: two patients who presented with orbital apex syndrome and cavernous sinus thrombosis succumbed to the disease; three patients suffered sensorineural hearing loss; and two patients had persistent facial palsy. One patient with sigmoid sinus thrombosis, who presented early, experienced complete recovery.
Insects in the ear can lead to hazardous complications. Animate foreign bodies should preferably be managed by a trained otologist, even in an emergency setting. Patients with delayed presentation and complications have a guarded prognosis.
