What is Cholesteatoma? 


 Cholesteatoma is an abnormal, noncancerous growth of skin cells in the middle ear and mastoid cavity. Despite being benign, this growth can expand over time, eroding surrounding structures, including bones of the middle ear, leading to hearing loss, infections, and balance disturbances. The condition may develop as a congenital defect or as a consequence of chronic ear infections, eustachian tube dysfunction, or trauma.

Cholesteatoma is relatively rare but carries significant risk due to its potential to destroy delicate ear structures and cause complications such as mastoiditis, labyrinthitis, facial nerve damage, or intracranial infections. Early detection and management are critical to prevent these serious outcomes.

THANC Hospital, Chennai, offers specialized care for cholesteatoma, with expertise in diagnosis, advanced imaging, and surgical management. Our ENT surgeons employ modern microsurgical techniques to remove cholesteatomas safely, preserve hearing, and prevent recurrence.

Understanding Cholesteatoma

Cholesteatoma arises when skin cells accumulate in the middle ear instead of shedding naturally through the ear canal. Over time, these trapped cells form a cyst-like mass that can expand, causing chronic infection and bone erosion.

Causes of Cholesteatoma

  • Acquired cholesteatoma:
    • Often develops due to chronic middle ear infections
    • Eustachian tube dysfunction leading to negative middle ear pressure
    • Trauma or repeated ear surgeries can contribute
  • Congenital cholesteatoma:
    • Present at birth due to developmental abnormalities
    • May remain undetected until later in childhood or adulthood
  • Secondary causes:
    • Chronic otitis media with effusion
    • Tympanic membrane retraction pockets

Risk Factors

  • Chronic ear infections or persistent fluid in the middle ear
  • Eustachian tube dysfunction, causing poor aeration of the middle ear
  • Previous ear surgery or trauma
  • Family history of ear disorders
  • Delayed treatment of acute or chronic ear infections

Who is Affected

  • Children: Congenital cholesteatomas or chronic ear infections can present in early childhood
  • Adults: Acquired cholesteatomas usually manifest in adulthood following recurrent ear infections
  • Both genders: Cholesteatoma affects males and females almost equally, although chronic ear infections may slightly increase prevalence in males

Common Symptoms of Cholesteatoma

Symptoms often develop gradually, and early detection is key to preventing complications.

Key Symptoms

  • Persistent or recurrent ear infections
  • Foul-smelling ear discharge (otorrhea)
  • Progressive hearing loss in one ear
  • Fullness or pressure in the ear
  • Ear pain or discomfort
  • Tinnitus (ringing in the ear)
  • Balance problems or dizziness if the inner ear is affected
  • Visible mass behind the eardrum upon otoscopic examination

When to Seek Medical Help

Patients should consult an ENT specialist if they experience:

  • Chronic ear discharge or recurrent infections
  • Progressive hearing loss or difficulty understanding speech
  • Persistent ear pain or pressure
  • Dizziness, vertigo, or imbalance
  • Facial weakness or numbness near the ear
  • Suspected cholesteatoma in children with delayed speech or hearing issues

Early intervention reduces the risk of bone destruction, nerve damage, and intracranial complications.

Diagnosis of Cholesteatoma

Accurate diagnosis requires careful clinical evaluation, audiological testing, and imaging studies.

Diagnostic Approach at THANC Hospital

THANC Hospital Chennai follows a comprehensive diagnostic protocol:

  • Otoscopy and microscopic examination:
    • Direct visualization of the tympanic membrane and middle ear
    • Identification of retraction pockets, cysts, or granulation tissue
  • Audiological assessment:
    • Pure-tone audiometry determines the type and degree of hearing loss
    • Speech audiometry evaluates comprehension and auditory processing
  • Imaging studies:
    • High-resolution CT scan of the temporal bone identifies the extent of cholesteatoma, bone erosion, and mastoid involvement
    • MRI may be used to differentiate cholesteatoma from other cystic lesions
  • Medical history evaluation:
    • Assessment of prior ear infections, surgeries, or trauma
    • Identification of congenital versus acquired cholesteatoma

Early diagnosis and imaging allow precise surgical planning, minimizing complications and ensuring complete removal of the growth.

Treatment Options for Cholesteatoma

Management typically involves surgical intervention, supported by medical therapies to control infection and inflammation.

Non-surgical / Medical Treatments

Although surgery is the definitive treatment, medical management plays an important role before and after procedures:

  • Antibiotic therapy:
    • Treats active infections or discharge prior to surgery
    • Oral or topical antibiotics may be prescribed based on culture results
  • Ear cleaning and suctioning:
    • Performed by ENT specialists to remove debris and prevent further infection
    • Helps maintain a healthy ear canal until surgical removal
  • Pain management:
    • Analgesics or anti-inflammatory medications for symptomatic relief
    • Supportive care for associated fever or discomfort
  • Hearing optimization:
    • Hearing aids may be considered in cases where surgery is delayed or as a temporary measure for hearing loss

Medical management alone cannot remove cholesteatoma but is essential to stabilize the ear and reduce infection before definitive surgical intervention.

Surgical / Advanced Treatments

Surgery is the primary treatment, aimed at complete removal of the cholesteatoma, prevention of recurrence, and restoration of hearing.

  • Mastoidectomy:
    • Removal of cholesteatoma from the mastoid bone
    • Can be canal wall up or canal wall down, depending on disease extent
  • Tympanoplasty:
    • Reconstruction of the tympanic membrane and ossicles to restore hearing
    • Often performed in combination with mastoidectomy
  • Ossicular chain reconstruction:
    • Rebuilding the chain of tiny ear bones to improve conductive hearing
  • Microsurgical techniques:
    • Use of high-powered microscopes for precise excision and minimal tissue damage
    • Ensures maximum preservation of healthy structures

Prevention & Lifestyle Tips

While congenital cholesteatoma cannot be prevented, acquired cholesteatoma can be minimized by:

  • Prompt treatment of ear infections to prevent chronic inflammation
  • Regular ENT check-ups for recurrent or persistent ear problems
  • Maintaining ear hygiene and avoiding insertion of foreign objects
  • Avoiding water entry in infected ears during bathing or swimming
  • Healthy lifestyle: Balanced diet, good hydration, and avoidance of smoking to support immune function
  • Managing coexisting conditions: Allergies or sinus issues that may worsen eustachian tube function
  • Monitoring children for delayed speech, recurrent ear infections, or hearing loss

Preventive strategies help reduce recurrence, maintain ear health, and preserve hearing function over time.
