Mastoid Surgery: Why It Is Done and What Recovery Involves

Mastoid surgery is an operation on the bone behind the ear, usually performed to treat long-standing infection, cholesteatoma, or complications affecting the middle ear. Understanding why it is done and what recovery involves can help patients feel more prepared and reassured.

Overview of mastoid surgery

Mastoid surgery, also called mastoidectomy, is a procedure performed on the mastoid bone, which sits just behind the ear. This bone contains small air-filled spaces that connect with the middle ear. When infection or abnormal skin growth spreads into these spaces, surgery may be needed to clear the disease and help prevent further damage.

The operation is most commonly recommended for people with chronic middle ear disease, repeated ear infections, or cholesteatoma, a noncancerous but potentially destructive growth of skin cells in the middle ear and mastoid. In some cases, it may also be used to help manage complications such as persistent ear discharge, bone erosion, or infection that does not respond to medicines.

Mastoid surgery is often combined with other ear procedures depending on what the surgeon finds. For example, the eardrum or tiny hearing bones may also need repair, sometimes as part of eardrum reconstruction. The main goals are to remove disease, create a safe and dry ear, and preserve or improve hearing whenever possible.

Why mastoid surgery is done

The most common reason for mastoid surgery is chronic ear disease that has caused ongoing inflammation or infection in the middle ear and mastoid air cells. Some patients have repeated ear discharge, hearing changes, discomfort, or a perforated eardrum that keeps returning despite medical treatment. Surgery may be advised when antibiotics, drops, or earlier procedures have not fully solved the problem.

Another major reason is cholesteatoma. Although it is not cancer, this condition can continue to expand and damage nearby structures if it is left untreated. It may erode the small hearing bones, affect the balance organs, and in severe cases increase the risk of deeper infection. In this setting, mastoid surgery is often the standard treatment to remove the disease as completely as possible.

Less commonly, mastoid surgery may be considered for complications of ear infection, certain tumors, or to gain access for specialized ear procedures. The surgeon may also evaluate related symptoms such as dizziness, ringing in the ears, or hearing loss to understand the full impact of the disease and plan the safest approach.

Symptoms and conditions that may lead to surgery

Patients who need mastoid surgery often have symptoms that have lasted for some time rather than a simple short-term ear infection. A common pattern includes ongoing or repeated drainage from the ear, hearing difficulty, a feeling of pressure, or discomfort that keeps returning. Some people also notice an unpleasant odor from the ear or a history of a perforated eardrum.

Other symptoms can suggest that disease has spread more deeply into the middle ear or mastoid. These may include dizziness, poor balance, ear fullness, and tinnitus. In children, parents may notice reduced hearing, inattentiveness, delayed speech development, or repeated ear problems requiring frequent medical visits.

The underlying conditions that can lead to surgery include:

• Chronic suppurative otitis media, a long-term middle ear infection with ear discharge
• Cholesteatoma
• Persistent eardrum perforation or tympanic membrane perforation
• Recurrent infections related to poor middle ear ventilation, sometimes associated with eustachian tube dysfunction
• Complications affecting the hearing bones or nearby structures

Not everyone with these problems needs surgery. The decision depends on symptoms, examination findings, hearing tests, imaging results, and whether the ear has improved with non-surgical care.

How doctors diagnose the problem and plan surgery

Assessment usually begins with a detailed history and ear examination by an ear, nose, and throat specialist. The doctor asks about infections, drainage, previous treatments, hearing changes, dizziness, and any prior ear surgery. The ear is then examined carefully, often with a microscope or endoscope, to look for perforation, trapped skin, inflammation, or cholesteatoma.

Hearing tests are an important part of planning. An audiogram helps measure the degree and type of hearing loss and gives a baseline for comparison after treatment. In many patients, a CT scan of the temporal bone is also used to show the mastoid air cells, middle ear spaces, hearing bones, and any areas of bone damage. This helps the surgeon decide how extensive the operation needs to be.

In some situations, the specialist may recommend treatment for active infection before surgery, such as cleaning the ear and prescribing antibiotic drops. Related services such as neurotology care may be involved when symptoms include complex hearing or balance concerns. The final surgical plan is tailored to the patient, taking into account the extent of disease, hearing goals, age, and overall health.

What happens during mastoid surgery

Mastoid surgery is usually performed under general anesthesia, so the patient is asleep and does not feel pain during the procedure. The surgeon typically makes an incision behind the ear or works through the ear canal, depending on the anatomy and the type of disease being treated. Using fine instruments and a surgical drill, the surgeon removes infected or abnormal tissue from the mastoid air cells and middle ear.

There are different types of mastoidectomy. In a simple or cortical mastoidectomy, the surgeon removes diseased mastoid air cells while preserving much of the ear’s normal structure. In more extensive procedures, such as canal wall up or canal wall down mastoidectomy, the approach depends on how far the disease has spread and the need to reduce the risk of recurrence. The surgeon balances disease clearance with hearing preservation and long-term ear care.

If needed, the procedure may be combined with repair of the eardrum or hearing bones. Some patients have simultaneous ear tube placement or reconstruction to improve middle ear ventilation and function. Before the operation, the surgeon explains the planned method, possible alternatives, and expected follow-up, because some ears require staged surgery or long-term monitoring after treatment.

Recovery after mastoid surgery

Recovery varies from person to person, but many patients go home the same day or after a short hospital stay. It is common to have mild pain, a sense of fullness around the ear, temporary muffled hearing because of packing, and some tiredness for several days. A small amount of blood-tinged drainage from the dressing or ear canal may occur early on, but this should gradually lessen.

The surgeon usually provides detailed instructions on keeping the ear dry, caring for the incision, using prescribed ear drops or medicines, and avoiding nose blowing, heavy lifting, or strenuous activity for a period of time. Follow-up visits are important because the doctor may need to remove packing, examine healing, and check for any remaining or recurrent disease. Hearing often cannot be judged accurately until swelling and packing have resolved.

Most people can return to light daily activities within days, but full recovery may take several weeks. If dizziness was present before surgery, it may take time to settle. In some cases, especially after extensive disease or reconstruction, long-term monitoring is needed. Near the end of recovery planning, some patients benefit from consultation in neuro-otology clinics when balance or hearing symptoms continue and require specialist follow-up.

Benefits, risks, and possible complications

The main benefit of mastoid surgery is control of disease. By removing chronic infection or cholesteatoma, the operation helps create a safer ear and lowers the risk of ongoing damage to bone, hearing structures, and nearby tissues. For many patients, it can reduce persistent drainage and make long-term ear care easier.

Like any surgery, mastoidectomy has risks. These may include bleeding, infection, scarring, changes in taste, temporary or permanent hearing changes, dizziness, ringing in the ear, and recurrence of the original problem. Because important structures pass through the area, there is also a small risk of facial nerve injury or leakage of inner ear fluid, though these complications are uncommon when surgery is performed by experienced specialists.

It is helpful for patients to remember that hearing outcomes depend greatly on the underlying disease and the condition of the eardrum and hearing bones before surgery. Sometimes the first priority is to remove disease safely, with hearing repair performed at the same time or in a later stage. A clear conversation with the surgeon can help set realistic expectations.

When to seek medical advice and ongoing care

Anyone with repeated ear infections, chronic ear drainage, worsening hearing, dizziness, or a known eardrum perforation should seek assessment from an ENT specialist. Early evaluation can help identify chronic middle ear disease before it causes more extensive damage. Prompt medical care is especially important if symptoms are one-sided, long-lasting, or associated with fever or significant pain.

After surgery, patients should contact their doctor if they develop worsening pain, fever, increasing redness or swelling, heavy bleeding, foul-smelling discharge, severe dizziness, vomiting, new facial weakness, or sudden hearing decline. These symptoms do not always mean a serious problem, but they should be checked promptly so the care team can advise the next steps.

Long-term care may include periodic ear examinations and hearing tests, particularly for cholesteatoma, which can recur even after careful surgery. Acibadem International’s multidisciplinary ENT specialists in JCI-accredited hospitals diagnose and treat ear conditions for international patients, including surgical follow-up when needed. Ongoing review and good ear care habits can help support the best possible result over time.

Frequently asked questions

Is mastoid surgery a major operation?

Mastoid surgery is a carefully planned ear operation that is usually done under general anesthesia. It is considered specialized rather than routine, but for many patients it is a standard treatment for chronic ear disease. The exact complexity depends on how extensive the infection or cholesteatoma is.

How long does recovery from mastoid surgery take?

Many people resume light activities within several days, but full healing often takes a few weeks. Hearing may seem blocked at first because of packing and swelling. Follow-up appointments are an important part of recovery and help the surgeon monitor healing.

Will mastoid surgery improve hearing?

It can improve hearing in some patients, especially if the eardrum or hearing bones are repaired. However, the main goal is often to remove disease and create a safe, dry ear. Hearing results depend on the extent of damage present before surgery.

Is mastoid surgery painful?

Most patients have mild to moderate discomfort for a short time after surgery rather than severe pain. This is usually managed with the medicines recommended by the surgeon. The area may feel tender, full, or numb while healing progresses.

Can cholesteatoma come back after mastoid surgery?

Yes, cholesteatoma can recur or persist in some cases, which is why regular follow-up is important. The risk depends on the type and extent of disease and the surgical technique used. Some patients need long-term monitoring or a second planned operation.

When should someone call the doctor after mastoid surgery?

A doctor should be contacted if there is fever, worsening pain, heavy bleeding, increasing swelling, bad-smelling discharge, severe dizziness, or new facial weakness. Sudden hearing changes after surgery should also be assessed. Prompt advice can help address problems early.
