Aural Myiasis
A 64-year-old man from a rural community presented to the emergency department with a 5-day history of pain, itching, and bleeding in the left ear. On physical examination, numerous mobile larvae were found to be occluding the left external auditory canal (Panel A and Video 1), a finding indicative of aural myiasis. An ear aspirator, forceps, and irrigation with sterile water were used to remove the larvae (Panel B and Video 2). Perforation of the tympanic membrane was identified on further examination of the left ear. Aural myiasis is an infestation of the middle or external ear by fly larvae of the order Diptera. Risk factors include chronic otitis media, diabetes mellitus, and impaired hygiene. Treatment involves removal of the larvae and irrigation of the ear to expel any remaining organisms. The patient was treated with topical and systemic antibacterial agents to prevent secondary infection and was referred to the otolaryngology department for possible tympanoplasty. Seven days later, the symptoms had resolved.
