Mosquitoes die in the ear, it is necessary to clean up, if not cleaned up may stimulate the secretion of cerumen glands and lead to cerumen embolism, and may lead to skin infection of the external auditory canal, which may lead to otitis externa, tympanitis and other diseases. 1. Cerumen embolism: If a mosquito dies in the ear and is not cleaned up, it will stimulate the cerumen glands of the ear to secrete cerumen and form a hard cerumen mass centered on the mosquito, resulting in cerumen embolism, which may affect the patient’s hearing. 2. Otitis externa: mosquitoes carry a large number of viruses and bacteria, if the mosquitoes are not cleaned out of the ear, it may lead to skin infection of the external auditory canal, and then otitis externa may occur, and the patient may have symptoms such as pain in the external auditory canal, edema, and increased secretion. 3. Tympanitis: If otitis externa is not properly disposed of, then the inflammation can continue to spread and tympanitis occurs, tympanitis can lead to hearing loss, tinnitus and other symptoms. If a mosquito dies in the ear, follow your doctor’s instructions for treatment.
