H71.02 Cholesteatoma of attic, left ear

Name of the Condition

• Cholesteatoma of attic, left ear

Summary

Cholesteatoma of the attic, left ear is a condition characterized by the abnormal growth of keratinizing squamous epithelium in the attic region of the left middle ear, leading to a non-cancerous but destructive lesion. This growth can erode surrounding structures, including the ossicles and the 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 a CT scan of the temporal bone, may be used to assess the extent of bony erosion and involvement of surrounding structures. Audiometric testing can help quantify hearing loss and determine its type (conductive, sensorineural, or mixed).

Treatment Options

Treatment typically involves surgical intervention to remove the cholesteatoma and repair any damaged structures, such as the ossicles or eardrum. Medical management may include antibiotics for secondary infections or topical treatments to control drainage. Postoperative follow-up is essential to monitor for recurrence and ensure proper healing.

Prognosis and Follow-Up

With appropriate treatment, the prognosis is generally good, though recurrence is possible. Regular follow-up appointments are necessary to assess hearing, check for residual or recurrent disease, and address any complications. Long-term monitoring may be required, especially if the condition was extensive or if there were pre-existing structural abnormalities.

Complications

Potential complications include permanent hearing loss, facial nerve paralysis, labyrinthitis (inner ear infection), meningitis, or brain abscess due to the spread of infection. These risks highlight the importance of timely diagnosis and management.

Lifestyle & Prevention

Preventive measures include managing chronic ear infections promptly, avoiding trauma to the ear, and seeking early evaluation for persistent ear symptoms. Smoking cessation and avoiding secondhand smoke may also reduce risk, as tobacco use can impair eustachian tube function.

When to Seek Professional Help

Seek medical attention if you experience persistent ear pain, drainage, hearing loss, dizziness, or a sensation of fullness in the ear. Early intervention can prevent progression and reduce the risk of complications.

Tips for Medical Coders

When coding for cholesteatoma of the attic, left ear, ensure the laterality (left ear) is clearly documented. The code H71.02 specifically denotes the left ear, so verify that clinical documentation supports this specification. Include details about the location (attic) and any associated findings, such as erosion or infection, to support accurate coding.
