H91.22

Clinical Causes: Inner ear infections or inflammation Viral infections affecting the auditory nerve Blood circulation issues in the ear or auditory pathways Autoimmune inner ear disease Trauma or injury to the head or ear Certain medications that are ototoxic Degenerative changes in the auditory system Stress or sudden exposure to loud noises

Key Symptoms: Sudden decrease in hearing ability in the affected ear A feeling of fullness or pressure in the ear Tinnitus, or ringing in the ear Dizziness or balance disturbances Sensitivity to loud sounds Possible ear pain or discomfort (less common)

Diagnosis Path: Diagnosis begins with a thorough medical history and physical examination by a healthcare professional. Audiometric testing, such as hearing tests, helps assess the degree of hearing loss. Additional tests may include imaging studies like MRI or CT scans to rule out other causes such as tumors or structural abnormalities. Blood tests might be performed to detect infections or autoimmune conditions. Identifying the exact cause can be challenging since many cases are idiopathic, meaning the cause remains unknown.

Treatment Protocols: While treatment approaches may vary, early intervention is crucial to potentially recover hearing. Common treatments include corticosteroids to reduce inflammation and swelling in the ear. In some cases, antiviral medications may be considered if a viral infection is suspected. Hearing aids or assistive listening devices can be helpful for managing residual hearing loss. Rehabilitation therapy, including auditory training and counseling, may assist with adaptation. Preventive measures like avoiding loud noises and managing cardiovascular health can support overall ear health.
