H91.01

Clinical Causes: Certain medications such as aminoglycoside antibiotics, some chemotherapy drugs (like cisplatin), and high doses of salicylates. Long-term exposure to loud noise, especially if combined with ototoxic drugs. Chemical exposure in occupational settings, including solvents and heavy metals. Genetic predispositions that can make the inner ear more vulnerable to toxins. Underlying health conditions, like infections or autoimmune diseases that may increase susceptibility to ototoxicity.

Key Symptoms: Hearing loss in the affected (right) ear that may be sudden or gradual. Tinnitus, or ringing in the ear. Feeling of fullness or pressure in the ear. Dizziness or balance problems in some cases. Difficulty understanding speech, especially in noisy environments.

Diagnosis Path: Diagnosis typically involves a comprehensive hearing assessment, including audiometry tests that measure hearing sensitivity in each ear individually. Medical history is also crucial to identify possible exposure to ototoxic agents, medication use, or noise exposure. Additional tests, such as otoacoustic emissions or auditory brainstem response studies, may be used to evaluate inner ear function. Collaboration with healthcare providers helps determine if medication adjustments or further investigations are necessary.

Treatment Protocols: Discontinuing or adjusting the dosage of the causative medication under medical supervision. Use of hearing aids to amplify sounds and improve hearing ability. Cochlear implants in severe cases where hearing aids are insufficient. Rehabilitation programs focusing on communication strategies. Monitoring and follow-up to evaluate hearing changes over time.
