H71.03 Cholesteatoma of attic, bilateral

Name of the Condition

• Cholesteatoma of attic, bilateral

Summary

Cholesteatoma of the attic, bilateral is a condition characterized by the abnormal growth of keratinizing squamous epithelium in the attic region of both middle ears, leading to non-cancerous but destructive lesions. This growth can erode surrounding structures, including the ossicles and attic bony walls, and may result in hearing loss or other complications. The condition often presents as a chronic or recurrent issue, requiring careful evaluation and management.

Causes

Cholesteatoma typically develops due to the migration of skin from the eardrum into the attic region, often secondary to chronic ear infections or eustachian tube dysfunction. Congenital factors, where skin cells are trapped during fetal development, can also contribute to its formation. In some cases, prior ear surgery or trauma may predispose to the condition.

Risk Factors

• Chronic otitis media (middle ear infection)
• Eustachian tube dysfunction
• Prior ear surgery or trauma
• Congenital abnormalities of the ear
• Recurrent ear infections in childhood

Symptoms

• Conductive hearing loss (often gradual)
• Ear pain or discomfort
• Drainage from the ear (may be foul-smelling)
• Dizziness or balance issues
• Sensation of fullness in the ear
• Possible facial nerve weakness (in advanced cases)

Diagnosis

Diagnosis is based on clinical evaluation, including otoscopic examination to identify the characteristic lesion in the attic region. Imaging studies, such as CT scans, may be used to assess the extent of bony erosion and involvement of surrounding structures. Audiometric testing can help quantify hearing loss.

Treatment Options

Treatment typically involves surgical removal of the cholesteatoma to prevent further damage and restore hearing. Postoperative care may include antibiotics to prevent infection and regular follow-up to monitor for recurrence. In some cases, hearing reconstruction may be necessary.

Prognosis and Follow-Up

With appropriate treatment, the prognosis is generally good, though recurrence is possible. Regular follow-up is essential to monitor for residual or recurrent disease and to address any hearing changes. Long-term management may be required to maintain ear health.

Complications

Potential complications include permanent hearing loss, facial nerve paralysis, labyrinthitis (inner ear inflammation), and intracranial spread of infection, which can lead to meningitis or brain abscess.

Lifestyle & Prevention

• Avoid inserting objects into the ears to prevent trauma or infection.
• Manage chronic ear infections promptly with appropriate medical care.
• Use hearing protection in noisy environments to preserve overall ear health.

When to Seek Professional Help

Seek medical attention if you experience persistent ear pain, drainage, hearing loss, or dizziness. Early evaluation is important to prevent progression and complications.

Tips for Medical Coders

When coding for cholesteatoma of the attic, bilateral (H71.03), ensure documentation specifies bilateral involvement and the attic region. Verify that the diagnosis aligns with clinical findings and imaging results to support accurate coding.
