H71.91

Clinical Causes: Recurrent or chronic middle ear infections (otitis media) Eustachian tube dysfunction, causing negative pressure and fluid buildup Previous ear surgery or trauma to the ear Congenital factors, where abnormal tissue growth occurs during development Eustachian tube dysfunction leading to retraction pockets, trapping skin debris

Key Symptoms: Hearing loss in the affected ear A feeling of fullness or pressure in the ear Discharge or foul-smelling fluid from the ear Earache or discomfort Persistent or recurrent infections Imbalance or dizziness in severe cases Tinnitus (ringing in the ear)

Diagnosis Path: Diagnosing a cholesteatoma involves a combination of clinical examination and diagnostic tests. An otolaryngologist (ear, nose, and throat specialist) will typically perform an otoscopic exam, using a specialized instrument to inspect the ear for abnormal tissue or growths. Additional imaging studies such as computed tomography (CT) scans may be ordered to assess the extent of the growth and any potential damage to ear structures. Audiometry tests can evaluate hearing loss caused by the condition.

Treatment Protocols: The primary treatment for cholesteatoma usually involves surgical removal of the growth. The goals of surgery are to eradicate the abnormal tissue, restore hearing function if possible, and prevent further complications such as infections or damage to nearby structures. Postoperative care may include follow-up examinations, ear cleaning, and in some cases, additional procedures to reconstruct damaged ear components. Antibiotics or corticosteroids might be prescribed if there is an associated infection or inflammation. Early intervention is important to avoid serious complications like hearing loss, dizziness, or the spread of infection to surrounding areas.
