Cholesteatoma — Dangerous Ear Growth, Symptoms & Surgery

What is Cholesteatoma?

Your ear has three main parts: the outer ear, the middle ear, and the inner ear. The middle ear is a small, air-filled space located just behind your eardrum. It contains three tiny bones that vibrate to help you hear. A cholesteatoma is an abnormal, non-cancerous skin growth that develops in this delicate middle section.

Normally, your skin sheds dead cells constantly. When this shedding happens inside a trapped pocket in your middle ear, the dead skin cells collect. They form an expanding sac or cyst.

Even though this growth is not a tumor, it behaves in a very destructive way. As the sac grows, it releases special enzymes. It also creates physical pressure that can destroy the delicate structures of your ear. This includes your tiny hearing bones, your balance organs, and even the thin bone separating your ear from your brain.

Chronic ear infections remain a massive public health issue in India. Medical studies show that among Indian patients suffering from chronic middle ear infections, the prevalence of this dangerous growth often exceeds 4% to 6%. The burden is especially high in rural areas where access to early medical care is limited.

Anyone can develop this condition, but it most often strikes individuals who have a long history of ear infections. Doctors see a peak incidence in young people between the ages of 10 and 20 years. If you have struggled with fluid in your ears since childhood, you carry a higher risk. You can learn more about our specialized care for these conditions on our Otology & Neuro-Otology page.

Causes and Risk Factors

To understand how this condition starts, you need to know about the Eustachian tube. This narrow tube connects the back of your throat to your middle ear. It works to equalize air pressure on both sides of your eardrum. Every time you swallow or yawn, this tube opens to let fresh air into your middle ear.

If your Eustachian tube does not work correctly, the air inside your middle ear absorbs into your body. This creates a vacuum or negative pressure. This negative pressure pulls the weakest part of your eardrum inward. The stretched eardrum forms a tiny pouch or retraction pocket. Old skin cells get trapped inside this pocket, eventually forming a cyst.

Causes of this condition fall into two main categories:

• Congenital causes: Rarely, babies are born with this condition. A tiny piece of skin gets trapped behind the eardrum while the baby develops in the womb. These cases often go unnoticed until the child fails a hearing test.
• Acquired causes: Most people develop this growth later in life. It usually happens after repeated ear infections, severe allergies, or a torn eardrum. You can read more about how eardrums tear in our guide to /blog/ear-drum-perforation-causes-symptoms-treatment.

Several specific factors make Indian patients more vulnerable to developing this condition:

• Tobacco use and smoke exposure: Active smoking and exposure to secondhand smoke severely irritate the Eustachian tube. In India, the widespread use of cigarettes and beedis significantly increases the risk of aggressive middle ear disease. Smoke paralyzes the tiny hairs that normally clean your respiratory tract.
• Climate and weather: The high humidity during the Indian monsoon season creates an ideal environment for bacterial and fungal infections. Frequent upper respiratory infections during this season often lead to middle ear complications.
• Diet and nutrition: A balanced diet keeps your immune system strong. In many parts of India, diets lacking essential nutrients like Vitamin A and Vitamin C leave individuals more susceptible to recurrent infections. Poor immunity allows simple ear infections to become chronic problems.
• Poor ear hygiene practices: Many people in India use unsterile objects like hairpins, matchsticks, or cotton swabs to clean their ears. This dangerous habit can damage the eardrum and introduce harmful bacteria, setting the stage for abnormal skin growths.

Signs and Symptoms

You might not notice any problems when the growth first starts forming. However, as the sac expands and becomes infected, it begins to cause noticeable issues. Recognizing these early warning signs can save your hearing and prevent serious complications.

Early warning signs you might notice first:

• Foul-smelling ear drainage: This is often the very first sign patients notice. You may experience a persistent, painless discharge coming from your ear. The fluid often smells bad and does not stop even after you take standard antibiotics. Learn more about this symptom in our article on /blog/chronic-ear-discharge-causes-treatment.
• Ear fullness or pressure: You might feel like your ear is blocked or plugged. It feels very similar to the sensation you get when flying in an airplane or driving up a steep mountain.
• Mild discomfort: While severe pain is rare early on, you may experience a dull, constant ache behind or inside your ear.

When symptoms progress and become serious:

As the growth gets larger, it starts to break down the tiny bones in your middle ear. These bones—the malleus, incus, and stapes—are essential for transmitting sound.

• Progressive hearing loss: You will likely notice that your hearing is slowly fading in the affected ear. This happens because the growth prevents your hearing bones from vibrating properly.
• Tinnitus: You may hear a constant ringing, buzzing, or roaring sound in your ear. This internal noise can become very distracting, especially in quiet environments.
• Dizziness or vertigo: If the growth erodes the bone protecting your inner ear, it can disrupt your balance system. You might feel like the room is spinning around you, making it difficult to walk or stand.
• Facial muscle weakness: The nerve that controls your facial muscles runs right through your middle ear. If the expanding cyst presses on this nerve, you might experience weakness or paralysis on one side of your face.

If left untreated for years, the cyst can erode the bone separating your ear from your brain. This can lead to life-threatening complications like meningitis or a brain abscess.

See a doctor if... You should book an appointment with an ear specialist immediately if you experience persistent ear drainage, sudden hearing loss, or any dizziness. Ignoring these symptoms allows the growth to cause permanent, irreversible damage to your hearing and balance systems.

How is Cholesteatoma Diagnosed?

When you visit the hospital, your doctor will start by asking detailed questions about your medical history. They will want to know about any past ear infections, previous ear surgeries, or family history of hearing problems. They will also ask exactly when your symptoms started and how they affect your daily life.

Clinical examination:

The doctor examines your ear using an otoscope (a handheld tool with a light and magnifying lens). For a much closer look, they will use a special surgical microscope. During this painless exam, the doctor looks for a retraction pocket, a hole in the eardrum, or a collection of white, pearl-like skin debris.

If your ear is draining, the doctor may gently clean your ear canal using a tiny suction device. This cleaning provides a clear view of your eardrum and helps the doctor assess the extent of the visible damage.

Tests and imaging available at THANC Hospital:

If your doctor suspects an abnormal growth, they will order specific tests to confirm the diagnosis and plan your treatment.

• Pure Tone Audiometry: This standard hearing test measures exactly how much hearing you have lost. You will sit in a soundproof booth and wear headphones. The audiologist will play various tones, and you will indicate when you hear them. They will also test your bone conduction by placing a small vibrating device behind your ear. This helps the doctor understand if the growth has damaged your hearing bones or your inner ear nerves.
• High-Resolution Computed Tomography (HRCT): This specialized CT scan takes detailed, cross-sectional pictures of your temporal bone (the skull bone containing your ear). The HRCT scan is absolutely important for surgical planning. It shows the exact size and location of the cyst. It also reveals whether the growth has eroded your hearing bones, your balance canals, or the bone separating your ear from your brain.

What to expect during evaluation:

You do not need to worry about the evaluation process. The physical exam and the hearing tests are completely painless and non-invasive. The CT scan takes only a few minutes and requires no special preparation. After the tests, your doctor will sit down with you, show you the scan results on a screen, and explain exactly what is happening inside your ear.

Treatment Options

A cholesteatoma will never heal or go away on its own. Because it continues to grow and destroy surrounding bone, you must have it medically treated. Delaying treatment only makes the eventual surgery more complicated and increases your risk of permanent hearing loss.

Conservative and medical management first:

When you first visit the clinic, your ear might be actively infected and draining. Your doctor will focus on clearing this active infection first. They will carefully clean your ear using microscopic suction to remove pus and debris. They will also prescribe strong antibiotic ear drops and sometimes oral antibiotics.

While these medical treatments stop the infection and dry up the ear, they do not cure the underlying problem. Medical management only controls the symptoms temporarily. It cannot dissolve or remove the skin cyst. To permanently remove the threat, you need surgery.

Surgical options when needed:

The primary and most effective treatment is cholesteatoma surgery. The main goal of this surgery is to completely remove the cholesteatoma and create a safe, dry ear. Restoring your hearing is an important, but secondary, goal. Your surgeon will prioritize removing all the disease to prevent life-threatening complications.

Depending on the size of the growth, your surgeon will perform one or a combination of these procedures:

• Tympanoplasty: The surgeon repairs the hole in your eardrum using a small piece of your own tissue. They usually take a tiny piece of cartilage from your outer ear or fascia (muscle covering) from above your ear. If the growth has damaged your hearing bones, the surgeon may rebuild them using tiny artificial implants or your own reshaped bone.
• Mastoidectomy: The mastoid is the honeycomb-like bone located just behind your ear. The growth often spreads from the middle ear into these air cells. During a mastoidectomy, the surgeon opens this bone to clean out all the trapped skin cells and infection. You can learn more about this specific procedure in our guide to /blog/tympanoplasty-mastoidectomy-ear-surgery-recovery.

Surgeons generally use two main approaches for a mastoidectomy:

• Canal Wall Up: The surgeon removes the disease but leaves the bony wall of your ear canal intact. This preserves the normal appearance of your ear canal and makes it easier to fit a hearing aid later. However, it carries a slightly higher risk of the growth returning.
• Canal Wall Down: The surgeon removes the back wall of the ear canal to create one large, open cavity. This technique makes it much easier for the doctor to monitor and clean your ear in the future. It significantly lowers the chance of the disease coming back, making it the preferred choice for large or aggressive growths.

Advanced techniques at THANC:

At THANC Hospital, our surgical team uses advanced microscopic and endoscopic technology when operating on cholesteatoma. Endoscopes are thin tubes with high-definition cameras and lights at the tip. They allow the surgeon to look around corners inside your middle ear. This helps them remove every single microscopic skin cell, reducing the risk of recurrence while preserving as much of your natural ear structure as possible.

Living with Cholesteatoma / Recovery and Outlook

Recovering from ear surgery requires patience and careful attention to your doctor's instructions. Your active participation in the recovery process directly impacts the success of your surgery.

What to expect after treatment:

Most patients go home the same day or the morning after their surgery. You will wake up with a bandage wrapped around your head to protect the ear and absorb any mild bleeding. Your surgeon will also place special packing material inside your ear canal. This packing holds the newly repaired tissues in place while they heal.

During the first week, you might experience mild dizziness, a temporary change in how food tastes, or a feeling of fullness in your ear. These symptoms usually fade within a few weeks. Your hearing might actually seem worse immediately after surgery because of the packing material and internal swelling. As your ear heals over the next two to three months, the swelling will go down, and your hearing will gradually improve.

Follow-up care:

This condition has a stubborn tendency to grow back, even after a highly successful surgery. Because of this, long-term follow-up care is absolutely critical. You will need to visit your ENT specialist regularly for ear cleanings and check-ups. During these visits, the doctor will use a microscope to ensure your ear remains healthy and free of disease.

In some cases, your surgeon may recommend a "second-look" surgery about six to twelve months after your first operation. During this minor procedure, the surgeon checks to ensure no microscopic skin cells have started growing again. They may also reconstruct your hearing bones during this second surgery if they could not do it safely during the first one.

Lifestyle modifications:

To protect your healing ear and prevent future problems, you need to make a few important lifestyle changes:

• Keep your ear strictly dry: Water can introduce bacteria and ruin the delicate surgical repair. You must use a cotton ball coated in petroleum jelly or a custom earplug whenever you shower or bathe. You must avoid swimming entirely until your doctor gives you explicit permission.
• Avoid heavy lifting and straining: For the first four to six weeks after surgery, avoid any activities that increase pressure in your head. This includes heavy lifting, intense gym workouts, and blowing your nose forcefully. If you need to sneeze, do so with your mouth open.
• Quit tobacco products: Smoking severely impairs your body's ability to heal by reducing blood flow to your tissues. It also damages your Eustachian tube function. Quitting smoking is one of the most important steps you can take to ensure a successful recovery and prevent future ear diseases.
• Manage your allergies: If you suffer from chronic sinus issues or seasonal allergies, work with your doctor to keep them under control. Healthy sinuses promote a healthy middle ear by allowing your Eustachian tube to function properly.
