Introduction
An insect (e.g., a mosquito) that has flown into the ear and died typically requires prompt medical intervention. Mosquitoes often carry substantial quantities of bacteria, viruses, and other pathogenic microorganisms; if left untreated, these may cause infection, leading to conditions such as otitis externa (outer ear infection), tympanitis (inflammation of the eardrum), or otitis media (middle ear infection). Under a physician’s guidance, normal saline irrigation may be used to flush out the insect, or an otoscope or operating microscope may be employed to safely remove the insect’s remains.

When a mosquito flies into the ear and dies, prompt medical intervention is generally required to prevent secondary infections.

Mosquitoes typically carry numerous bacteria, viruses, and other pathogenic microorganisms. If a dead mosquito remains in the ear canal without removal, prolonged retention may lead to infection by these pathogens, resulting in otitis externa—characterized by redness, swelling, and pain. In more severe cases, it may trigger tympanitis (inflammation of the eardrum), causing tympanic membrane congestion, or even progress to otitis media, manifesting as otorrhea (ear discharge) or purulent drainage. Such complications can significantly impair the patient’s health.

After a mosquito enters and dies inside the ear, prompt consultation with an otolaryngologist (ENT specialist) is recommended. If the tympanic membrane remains intact and there are no obvious signs of inflammation—such as marked erythema, swelling, or pain in the external auditory canal—the physician may safely irrigate the ear canal with normal saline under direct supervision. If irrigation proves ineffective, an otoscope or operating microscope-assisted microsuction or forceps removal may be performed to extract the insect’s remains.

In daily life, protective measures should be taken to safeguard the ear canal and prevent insects from entering and causing adverse symptoms.
