ICD-10: H93.3

The ICD-10 code H93.3 pertains to "Disorders of acoustic nerve," which encompasses a range of conditions affecting the eighth cranial nerve, also known as the vestibulocochlear nerve. This nerve is crucial for hearing and balance, and disorders associated with it can lead to various auditory and vestibular symptoms.

Clinical Description

Overview of Acoustic Nerve Disorders

Disorders of the acoustic nerve can manifest in several ways, primarily affecting hearing and balance. The vestibulocochlear nerve is responsible for transmitting sound and equilibrium information from the inner ear to the brain. When this nerve is compromised, patients may experience symptoms such as:

• Hearing Loss: This can be conductive, sensorineural, or mixed, depending on the underlying cause.
• Tinnitus: A perception of noise or ringing in the ears, which can be persistent or intermittent.
• Balance Issues: Patients may experience dizziness, vertigo, or unsteadiness due to the vestibular component of the nerve being affected.

Common Causes

Several conditions can lead to disorders of the acoustic nerve, including:

• Acoustic Neuroma: A benign tumor that develops on the vestibulocochlear nerve, leading to hearing loss, tinnitus, and balance problems.
• Vestibular Neuritis: Inflammation of the vestibular nerve, often resulting from viral infections, causing sudden vertigo.
• Meniere's Disease: A disorder characterized by episodes of vertigo, hearing loss, tinnitus, and a feeling of fullness in the ear, linked to fluid buildup in the inner ear.
• Trauma: Head injuries can damage the acoustic nerve, leading to immediate or delayed symptoms.

Diagnosis

Diagnosis of disorders related to the acoustic nerve typically involves:

• Audiometric Testing: To assess hearing function and identify the type and degree of hearing loss.
• Imaging Studies: MRI or CT scans may be used to visualize any structural abnormalities, such as tumors or lesions affecting the nerve.
