Introduction
Hearing loss in one ear while the other ear has normal hearing may be caused by conditions such as cerumen impaction, otitis media, external otitis, sudden sensorineural hearing loss, or tympanic membrane perforation. Treatment should follow medical advice and may include sodium bicarbonate injection, ofloxacin ear drops, lomefloxacin hydrochloride ear drops, vitamin B1 tablets, chloramphenicol ear drops, or surgical interventions such as tympanoplasty.

Hearing well in one ear but poorly in the other may be caused by conditions such as cerumen impaction, otitis media, external otitis, sudden sensorineural hearing loss, or tympanic membrane perforation.

1. Cerumen Impaction

This may occur when cerumen (earwax) accumulates in one ear and is not promptly removed, leading to blockage and resulting in asymmetric hearing. It is recommended that a healthcare professional uses sodium bicarbonate injection to soften and remove the impacted cerumen to relieve symptoms.

2. Otitis Media

Inflammation in the middle ear of one side may interfere with normal sound transmission, causing the described hearing imbalance. This condition may also be accompanied by symptoms such as pus discharge from the ear or a feeling of ear fullness. Treatment may include medications such as amoxicillin capsules, ofloxacin ear drops, or metronidazole tablets, as prescribed by a doctor, to help resolve the infection.

3. External Otitis

Inflammation of the external auditory canal often causes local tissue swelling, obstructing the ear canal and disrupting sound conduction to the inner ear, leading to unilateral hearing loss. Symptoms may include ear discharge. Under medical guidance, treatment may involve antibiotic ear drops such as levofloxacin hydrochloride ear drops, ciprofloxacin hydrochloride ear drops, or lomefloxacin hydrochloride ear drops to reduce infection.

4. Sudden Sensorineural Hearing Loss

This may result from prolonged exposure to noisy environments, chronic sleep deprivation, or high stress levels, leading to sudden hearing loss in one ear, possibly accompanied by tinnitus. As directed by a physician, neurotrophic medications such as mecobalamin tablets, oryzanol tablets, or vitamin B1 tablets may be used to support nerve function recovery.

5. Tympanic Membrane Perforation

Damaged integrity of the eardrum in one ear can impair sound transmission, causing asymmetric hearing. This may also be associated with ear pain. Under medical supervision, treatment options may include ofloxacin ear drops, chloramphenicol ear drops, or ibuprofen sustained-release tablets for symptom relief. In some cases, surgical intervention such as tympanoplasty (eardrum repair surgery) may be necessary.

Patients are advised to seek timely medical evaluation for accurate diagnosis and appropriate treatment as prescribed. Maintaining healthy lifestyle habits and minimizing ear irritation are also recommended.

Why can't women eat taro?
Women can eat taro, but there are some reasons why it might not be suitable for them, such as potentially causing indigestion, triggering allergic reactions, increasing gastrointestinal burden, or affecting blood sugar stability. Taro is rich in starch and digests slowly; excessive consumption may cause food to remain in the intestines too long, leading to fermentation and discomfort.
