Chronic Middle Ear Disease

Introduction

Chronic middle ear disease is a long-standing problem in the middle ear — the small, air-filled space behind the eardrum — that does not fully heal with simple antibiotics. If you or a family member has been told you have a hole in the eardrum that keeps draining, repeated ear infections that never seem to settle, or a condition called cholesteatoma, this article is for you.

Living with chronic ear disease can be frustrating. Hearing slowly fades. Discharge returns just when you think the ear has finally healed. Swimming, flying, and even a head wash become a worry. The good news is that, with consistent care from an ENT specialist, most people can achieve a dry, stable, and safer ear — and often regain useful hearing.

This guide explains what chronic middle ear disease is, why it develops, how it is diagnosed, and the treatments doctors commonly use. It covers both medical management and the main types of ear surgery, and what recovery and long-term care usually involve.

What Is Chronic Middle Ear Disease?

The middle ear sits behind the eardrum (also called the tympanic membrane). Inside this space are three tiny bones — the malleus, incus, and stapes — that pass sound vibrations from the eardrum to the inner ear. The middle ear is connected to the back of the nose by a narrow tube called the Eustachian tube, which keeps the air pressure balanced and helps drain fluid.

An acute middle ear infection (acute otitis media) usually clears up within a few days or weeks. Chronic middle ear disease is different. It is a state of long-term infection, inflammation, or structural damage that lasts months or years. Doctors may also use related terms such as chronic otitis media, chronic suppurative otitis media (CSOM), or refer to a specific complication such as cholesteatoma.

Over time, ongoing disease can damage:

• The eardrum — producing a hole (perforation) that may not heal on its own
• The middle ear lining — making it thickened and prone to discharge
• The hearing bones (ossicles) — eroding them and reducing hearing
• Nearby structures — including the mastoid bone behind the ear, the facial nerve, and rarely the brain or inner ear

Because the disease is chronic, the goal of treatment is not only to stop the current infection but to create a safe, dry ear that resists future problems and protects hearing for the long term.

Types of Chronic Middle Ear Disease

Chronic middle ear disease is not a single illness. ENT doctors usually describe it in a few main forms, and your care plan depends on which form you have.

Chronic Suppurative Otitis Media (CSOM)

This is the most common form worldwide. There is a long-standing hole in the eardrum together with recurrent or continuous discharge from the ear. The discharge may be watery, mucky, or thick. The disease is often called the “tubotympanic” or “safe” type, because it usually does not involve dangerous complications — though it can still cause significant hearing loss.

Cholesteatoma

Cholesteatoma is a growth of skin in the wrong place — in the middle ear or mastoid bone. Despite the name, it is not a cancer. The trapped skin keeps shedding and forms a pocket that gradually expands, erodes bone, and becomes infected. Cholesteatoma is sometimes called the “unsafe” type of chronic ear disease because it can damage hearing bones, the balance organs, the facial nerve, and rarely spread to the brain. It almost always requires surgery.

Chronic Otitis Media with Effusion (Glue Ear)

Here, the eardrum is intact but fluid sits in the middle ear for weeks or months without acute infection. It is most common in children and causes muffled hearing rather than pain or discharge.

Adhesive Otitis Media and Tympanosclerosis

Long-standing inflammation can cause the eardrum to stick to the structures behind it (adhesive otitis media) or develop chalky white patches of scarring (tympanosclerosis). Both can affect hearing.

Dry Tympanic Membrane Perforation

Some people have an old hole in the eardrum that no longer discharges but still affects hearing and limits activities like swimming. This is sometimes managed surgically even though the ear is currently dry.

Causes and Risk Factors

Chronic middle ear disease usually develops over time and often has more than one cause. Common contributors include:

• Repeated childhood ear infections that did not fully resolve
• Eustachian tube dysfunction — when the tube connecting the middle ear to the back of the nose does not open properly, the middle ear cannot ventilate or drain
• Long-standing eardrum perforations from previous infection or injury
• Chronic nasal or sinus problems, allergies, or enlarged adenoids in children
• Cleft palate and other craniofacial conditions that affect Eustachian tube function
• Smoking and exposure to second-hand smoke
• Living in environments with poor air quality, crowding, or limited access to early ear care
• Previous ear surgery with residual or recurrent disease

Cholesteatoma can develop from a deep retraction pocket of the eardrum, from skin migrating through an old perforation, or, less often, as a condition present from birth (congenital cholesteatoma).

Signs and Symptoms

Most readers of this article already know they have a chronic ear problem. Still, it helps to recognise which symptoms suggest the disease is active or progressing, so you can act early.

Common symptoms include:

• Ear discharge — clear, mucky, or foul-smelling. Foul-smelling discharge can suggest cholesteatoma.
• Hearing loss in the affected ear, often gradual
• A feeling of fullness or blockage
• Tinnitus (ringing or buzzing in the ear)
• Ear pain — usually mild; severe pain may indicate a complication
• Dizziness or imbalance — less common, but important to report

Warning signs that need urgent ENT review include sudden worsening of hearing, severe pain, facial weakness on the side of the affected ear, severe dizziness, high fever, neck stiffness, or swelling behind the ear. These can suggest that infection is spreading beyond the middle ear.

Diagnosis

Diagnosis of chronic middle ear disease combines a careful history, examination of the ear, hearing tests, and sometimes imaging. The aim is to confirm what type of disease is present, how much damage has occurred, and what hearing remains.

Ear Examination

The ENT specialist uses an otoscope or, more often, an operating microscope or rigid endoscope to look closely at the ear canal and eardrum. They will look for perforations, retraction pockets, discharge, skin debris, and signs of cholesteatoma. The ear canal may need to be gently cleaned (microsuction) before a clear view is possible.

Hearing Tests (Audiometry)

• Conductive hearing loss — sound is not being passed properly through the eardrum or hearing bones. This is the typical pattern in chronic middle ear disease and is often partly or fully treatable.
• Sensorineural hearing loss — the inner ear or hearing nerve is affected. This pattern is less easily reversed.
• Mixed hearing loss — both elements together.

Speech audiometry assesses how clearly you understand words. In children, age-appropriate tests are used.

Tympanometry

This quick test measures how the eardrum moves in response to changes in air pressure. It helps detect fluid in the middle ear, perforations, or stiffness.

Imaging

A high-resolution CT scan of the temporal bone is often ordered before surgery, particularly when cholesteatoma is suspected or when complications are a concern. It shows the state of the mastoid bone, the hearing bones, the facial nerve canal, and the inner ear. MRI may be added in selected cases, especially to look for residual cholesteatoma after surgery or to evaluate possible spread of infection.

Other Investigations

If discharge is not responding to standard treatment, a swab may be sent for culture to identify the bacteria or, less often, fungi involved. Allergy or nasal evaluation may be considered if Eustachian tube problems are prominent.

Treatment and Management

Treatment is shaped by the type of disease, how much damage is present, the state of hearing, and your overall health. ENT specialists generally combine medical care to control infection with surgery when needed to restore a safe and functional ear.

Medical Management

Medical treatment is often the first step and may be enough on its own for milder forms of chronic suppurative otitis media without cholesteatoma. It usually includes:

• Ear cleaning (aural toileting) — gentle removal of discharge and debris under the microscope, sometimes repeated over weeks. This is one of the most effective parts of treatment.
• Topical antibiotic ear drops — commonly quinolone-based drops, which are recommended by current evidence reviews because they are effective and avoid the inner-ear risks of older drops.
• Topical steroid combinations — to reduce inflammation when the ear is very swollen or producing thick discharge.
• Oral antibiotics — usually reserved for severe infection, infection that has spread, or specific bacteria identified on culture.
• Antifungal treatment — when fungal infection (otomycosis) is present.
• Treating contributing factors — nasal allergies, sinusitis, reflux, or smoking exposure.
• Keeping the ear dry — protecting the ear during showering and avoiding swimming while it is discharging.

Surgery for chronic middle ear disease has two main goals: to make the ear safe (remove disease and prevent complications) and to make the ear functional (repair the eardrum and hearing mechanism). The specific operation depends on the disease.

Tympanoplasty is a broader operation that repairs the eardrum and, if needed, reconstructs the hearing bones using either the patient’s own remodelled ossicles or small prostheses. It is used when disease has affected both the eardrum and the middle ear.

Mastoidectomy involves opening and clearing the mastoid bone behind the ear, where chronic disease and cholesteatoma can spread. There are different forms:

• Cortical (simple) mastoidectomy — removes infected air cells while keeping the ear canal wall intact.
• Canal-wall-up mastoidectomy — preserves the ear canal anatomy, often combined with tympanoplasty.
• Canal-wall-down (modified radical or radical) mastoidectomy — removes the back wall of the ear canal to create an open cavity. This may be needed for extensive cholesteatoma. It creates an “open” ear that needs occasional cleaning for life but reduces the risk of disease being left behind.

Ossiculoplasty is the reconstruction of the small hearing bones, often as part of tympanoplasty. Damaged or eroded bones are replaced with a partial or total ossicular prosthesis to restore sound transmission.

Ventilation tube (grommet) insertion is a small procedure where a tiny tube is placed through the eardrum to ventilate the middle ear. It is used most often in children with persistent glue ear, and sometimes in adults with severe Eustachian tube dysfunction.

Endoscopic ear surgery is an increasingly common approach, using a thin endoscope through the ear canal rather than a wider incision behind the ear. It is well-suited to many tympanoplasties and selected cholesteatoma cases.

Most ear surgery is performed under general anaesthesia. Hospital stay ranges from same-day discharge to a short admission, depending on the procedure.

Hearing Rehabilitation

Where surgery cannot fully restore hearing, or while waiting for surgery, hearing aids are an important option. For some forms of severe conductive or mixed hearing loss, bone-conduction devices or implantable hearing devices may be considered. The choice depends on the type and degree of hearing loss and is discussed with an ENT specialist and audiologist.

Lifestyle and Self-Management

Self-management plays a major role in keeping chronic ear disease under control between visits.

• Keep the ear dry when advised. Use a cotton ball coated with petroleum jelly, a custom ear plug, or a swim cap while bathing if your ENT recommends water precautions.
• Avoid inserting cotton buds or other objects into the ear canal — they push wax and debris deeper and can injure healing tissue.
• Treat colds and nasal allergies promptly. Blow your nose gently, one nostril at a time.
• Avoid smoking and exposure to second-hand smoke, which worsens Eustachian tube function.
• Be careful with flying and diving if the ear has a perforation or you have had recent surgery; ask your ENT for specific guidance.
• Use prescribed ear drops correctly: lie on your side, instil the drops, and gently press the small flap in front of the ear (the tragus) a few times to help the drops reach inside.
• Protect your hearing from loud noise.

Monitoring and Follow-up

Chronic middle ear disease is a long-term condition and benefits from regular follow-up, even when the ear feels well.

Typical monitoring may include:

• Periodic ENT review with microscopic ear examination
• Hearing tests to track stability or change
• Cleaning of an open mastoid cavity, often once or twice a year
• Imaging when there is concern about recurrence, especially after cholesteatoma surgery

Complications

Most people with chronic middle ear disease never develop serious complications, especially with appropriate care. However, untreated disease — particularly cholesteatoma — can lead to:

• Progressive hearing loss, sometimes permanent if the inner ear is affected
• Erosion of the hearing bones
• Mastoiditis — infection spreading into the mastoid bone
• Labyrinthitis — inflammation of the inner ear, causing vertigo
• Facial nerve weakness on the side of the affected ear
• Intracranial complications such as meningitis or brain abscess (rare but serious)

Surgery itself carries risks, including bleeding, infection, dizziness, changes in taste on one side of the tongue, tinnitus, hearing loss including rare complete loss of hearing in the operated ear, facial nerve injury, and the possibility that disease may recur and need further surgery. Your ENT surgeon will discuss the specific risks for your case before any operation.

Living with Chronic Middle Ear Disease

For many people, chronic ear disease becomes a long-term part of life rather than a single illness to be cured once. Practical adjustments help:

• Communicate hearing needs at work, school, or with family. Sitting on the better-hearing side, asking people to face you, and reducing background noise all help.
• Use hearing technology if recommended — hearing aids today are discreet and effective.
• Plan around water exposure rather than avoiding all activities. Many people with stable ears can swim with custom plugs, with the agreement of their ENT.
• Tell flight crews or anaesthesiologists about your ear history before flights or surgeries, so they can advise on pressure changes.
• Seek support if hearing loss is affecting mood, work, or relationships. Audiologists and counsellors can help.

Chronic Middle Ear Disease in Children

Children are particularly prone to middle ear problems because their Eustachian tubes are shorter, narrower, and more horizontal than in adults. The pattern of chronic ear disease in children differs in important ways.

Common Forms in Children

Chronic otitis media with effusion (glue ear) is very common, often after repeated colds or upper respiratory infections. Many children get better without treatment, which is why a period of watchful waiting (commonly around three months) is usually recommended before considering surgery, in line with current ENT guidelines.

Chronic suppurative otitis media with persistent perforation and discharge also occurs in children. Cholesteatoma can develop in childhood and tends to behave more aggressively in younger patients.

Impact on Development

Even mild but persistent hearing loss can affect speech development, learning, attention, and behaviour in young children. For this reason, hearing assessment and timely treatment are particularly important.

Treatment in Children

Management may include monitoring, medication, and surgery. Common pediatric procedures include:

• Ventilation tubes (grommets) — for persistent glue ear with hearing loss or recurrent infections
• Adenoidectomy — removal of the adenoids, often combined with grommets in selected children
• Tympanoplasty and mastoid surgery — for chronic perforations or cholesteatoma, usually planned at an appropriate age

Children with cleft palate, Down syndrome, or other conditions affecting the head and neck are at higher risk and often need closer ENT follow-up from an early age.

Preventing Recurrence and Complications

While not every case can be prevented, several steps reduce the risk of recurrence and complications:

• Complete the full course of any prescribed treatment, even when symptoms improve
• Attend follow-up appointments and hearing tests as scheduled
• Treat colds, allergies, and sinus problems early
• Avoid smoking and second-hand smoke exposure
• Protect the ear from water as advised by your ENT
• Vaccinate children according to national schedules — including pneumococcal and influenza vaccines, which reduce the risk of ear infections
• Breastfeed infants where possible, as this is associated with fewer ear infections
• Seek prompt evaluation for any new ear discharge, hearing change, dizziness, or facial weakness

When to Seek Urgent Care

Most flare-ups of chronic ear disease can be handled at a routine ENT appointment. However, certain symptoms suggest a possible serious complication and need urgent assessment:

• Severe ear pain with high fever
• Sudden hearing loss in the affected ear
• Severe or persistent vertigo
• Weakness or drooping on one side of the face
• Swelling, redness, or tenderness behind the ear
• Severe headache, neck stiffness, vomiting, confusion, or seizures

If any of these occur, do not wait for a scheduled appointment — seek urgent medical care.

Frequently Asked Questions

Will my hearing come back to normal after treatment?

It depends on what is causing the hearing loss. If the problem is mainly in the eardrum or hearing bones (conductive loss), surgery often improves hearing significantly. If the inner ear has been affected (sensorineural loss), hearing may not fully return. A hearing test before surgery gives a much clearer picture of what to expect, and your ENT can discuss likely outcomes for your specific situation.

Is cholesteatoma cancer?

No. Despite its name, cholesteatoma is not a cancer. It is a growth of normal skin in the wrong place. However, it can behave aggressively by eroding bone and damaging important nearby structures, which is why it almost always needs surgery.

Can chronic middle ear disease be cured without surgery?

Some cases — particularly mild chronic suppurative otitis media without cholesteatoma — can be controlled long-term with medical treatment, ear cleaning, and careful self-management. Other cases, especially cholesteatoma or repeated discharge that does not settle, generally require surgery. The decision is made with your ENT based on the type and extent of disease.

Can I swim or fly with chronic middle ear disease?

It depends on the state of your ear. With an actively discharging ear or a fresh perforation, doctors usually advise against swimming. Many people with stable, healed ears can swim with proper precautions. Flying is generally safe but can be uncomfortable; talk to your ENT before flying soon after ear surgery.

How long does recovery take after ear surgery?

Most people return to light activities within a week or two. The eardrum and middle ear continue to heal over weeks to months. Hearing often takes several weeks to settle as packing dissolves and swelling reduces. Your surgeon will give specific guidance for your operation.

Will the disease come back after surgery?

Recurrence is possible, especially after cholesteatoma surgery. This is why regular follow-up, sometimes with imaging or a planned second-look procedure, is important. Many recurrences are caught early and treated effectively.

Can chronic middle ear disease affect balance?

Yes. The inner ear, which controls balance, sits very close to the middle ear. Long-standing disease — particularly cholesteatoma — can occasionally affect balance, causing dizziness or unsteadiness. New or severe dizziness should always be evaluated by an ENT.

Is chronic middle ear disease contagious?

The disease itself is not contagious. The infections that can trigger flare-ups (such as colds) are spread from person to person, but the chronic ear condition is not passed directly to others.

Conclusion

Chronic middle ear disease is a long-term condition that needs steady, structured care rather than a single quick fix. Modern ENT practice offers a wide range of options — from careful ear cleaning and topical medications to advanced microsurgery and endoscopic techniques — that can stop chronic infection, repair damage, and protect or restore hearing.

The most important steps are early and accurate diagnosis, a clear understanding of which type of disease is present, and a partnership with an experienced ENT specialist who follows the ear over time. With consistent treatment and follow-up, most people achieve a dry, stable, and safer ear, and continue to live full and active lives.
