Cavity Problems After Mastoid Surgery and Their Management
By Dr. Sagar Rajkuwar, MS-ENT — ENT Specialist, Nashik, Maharashtra, India
🌐 www.entspecialistinnashik.com
Cholesteatoma and chronic ear disease can be successfully managed with mastoid surgery. Following surgery, however, some individuals experience issues in the mastoid cavity. Recurrent infections, chronic ear discharge, granulation tissue, accumulation of wax or debris, tinnitus, dizziness, or trouble utilizing a hearing aid may all be symptoms of this condition.
Poor surgery is not always the cause of a difficult mastoid cavity. The anatomy of the cavity, the healing process, and the postoperative care are all influenced by the underlying ear disease.
Important: Not every mastoidectomy creates a permanent open cavity. Cavity-related problems are particularly associated with canal-wall-down (CWD) mastoidectomy, in which the mastoid and ear canal are connected to create an open cavity.

1. What Is a Mastoid Cavity?
The mastoid bone is located at the back of the ear. It has air-filled chambers that connect to the middle ear.
In some forms of mastoid surgery, especially canal-wall-down mastoidectomy, diseased mastoid air cells are extracted and the mastoid is connected to the outer ear canal.
As a result, a mastoid bowl or mastoid cavity is produced.
To remove illness and establish a safe ear is the goal. It may be challenging to keep an open cavity clean and dry, though.
Long-term issues may include the following:
- Frequent ear discharge
- Accumulation of wax and other debris
- Tissue granulation
- Repeated infection
- Difficult to clean the cavity
- Dizziness caused by air or chilly water entering the cavity.
- ringing in the ear
- Deafness
- Problems donning or wearing a hearing aid
Large cavities, bony overhangs, cholesteatoma, residual infected cells, perforation, and insufficient meatoplasty have all been linked to troublesome mastoid cavities in research.
2. Why Is Mastoid Surgery Performed?
A few disorders might necessitate mastoid surgery, including:
- Cholesteatoma
- Otitis media suppurative chronica
- Long-standing mastoid infection
- Continuous middle ear infection
- Chronic ear infection complications
- Access to the middle or inner ear is necessary for certain selected situations.
One significant rationale for mastoidectomy is cholesteatoma.
A cholesteatoma is an unusual accumulation of skin cells in the mastoid or middle ear. If it keeps expanding, it could harm adjacent organs like the facial nerve, balance system, and small hearing bones.
Hence, the main objective of surgery is to remove sickness and establish a secure ear.
3. What Causes Cavity Problems After Mastoid Surgery?
A persistent or bothersome mastoid cavity might have several causes.
1. Persistent or recurring illness
If infected tissue or cholesteatoma remains or reappears, the cavity may become unwell and begin discharging.
2. Poorly formed or enormous aperture
It can be difficult to clean yourself if you have a really huge cavity. Deeper regions have the potential for debris to accumulate.
3. Overhanging bones
A bony overhang might hinder appropriate drainage and make it challenging for the patient and ENT specialist to examine the cavity.
4. High facial ridge
A pocket that accumulates moisture and garbage can form from a facial ridge that has not been adequately lowered.
5. Limited ear canal aperture
Examination and cleaning can be challenging due to a tight external auditory canal.
6. Meatoplasty that is not adequate
The ear canal’s opening is widened by a meatoplasty. Cleaning and ventilating the cavity may be challenging if the hole is too tiny.
7. Granulation tissue
Granulation tissue might form during the healing process. Discharge or blockage can result from excessive granulation.
8. Bad epithelialization
Healthy skin must line the cavity. Chronic inflammation and discharge might result from delayed or insufficient epithelialization.
9. Preserved mastoid cells
Occasionally, persistent infection may result from residual sick or poorly ventilated cells.
10. Postoperative care problems
Proper follow-up is frequently required for a mastoid cavity. Issues may result from an accumulation of wax, keratin, or trash if it is not cleaned away.
4. Common Symptoms of Mastoid Cavity Problems
A problematic cavity doesn’t always show the same signs in every patient.
Common symptoms include:
Ear discharge
One of the most important signs is discharge that is persistent or recurs.
The discharge could be:
- Thin
- dense
- Pus-like
- Stinky
- Irregular
Hearing loss
Hearing loss may persist as a result of the original ear disease, damage to the hearing bones, issues with the tympanic membrane, or other alterations in the middle ear.
Accumulation of wax and other debris
Open mastoid cavities can accumulate:
- Wax
- Keratin
- Skin that has died.
- Humidity
- Rubbish
Granulation tissue
During microscopic examination, granulation may be seen.
Ear discomfort
Patients may experience:
- Otitis
- Satiety
- Anger
- Delicacy
Tinnitus
Some patients may still hear a ringing, humming, hissing, or other noise in their ear.
Dizziness
Some patients may have vertigo, especially if exposed balance systems in an open cavity are stimulated by cold water or air.
Issues Using Hearing Aids
Hearing aids may be difficult or unpleasant to use in an area that is persistently wet or diseased.
5. Why Does a Mastoid Cavity Continue to Discharge?
There may be several causes for ongoing discharge.
The ENT specialist needs to ascertain if the discharge is due to:
- Infection
- Granulation tissue
- A residual cholesteatoma
- A cholesteatoma that returns
- Retained debris
- Poor cavity architecture
- Insufficient drainage
- Tight meatus
- Chronic middle-ear illness
- A hole or other structural flaw
As a result, continuous discharge shouldn’t be handled with ear drops repeatedly without determining the underlying cause.
Although some troublesome cavities might be resolved with careful cleaning and proper topical therapy, others need revision surgery.
6. How Is a Problematic Mastoid Cavity Diagnosed?
A thorough ENT examination is used to make the diagnosis.
Examination under an otoscope or microscope
The ENT doctor looks at:
- The auditory canal
- Membrana tympani
- Cavity of mastoid
- granulation tissue
- Wax
- Keratin
- To discharge
- Possible recurrent or leftover illness
The cavity may be examined in greater detail under the microscope.
Oral hygiene
The professional may carefully remove:
- Wax
- Rubbish
- Keratin
- Granulation tissue
Additionally, this might aid in determining if the cavity gets better after cleaning.
Hearing test
To ascertain the kind and degree of hearing loss, an audiogram can be taken.
CT scan
A CT scan of the temporal bone may be advised if the anatomy or the state of the condition requires more investigation.
It might aid in evaluating:
- Mastoid anatomy
- alterations to the bones
- Remaining air cells
- Bone abnormalities
- Recurrent disease is possible.
MRI scans
MRI, especially diffusion-weighted imaging in specific cases, could be beneficial if cholesteatoma is thought to be persistent or recurring.
The patient’s history and examination determine the precise investigation.
7. Medical Management of a Mastoid Cavity
Not every patient requires an additional procedure.
The state of the cavity determines the treatment.
Routine skilled cleaning
Periodical cleaning by an ear, nose, and throat doctor is helpful to some patients.
Careful suctioning of: may be part of this.
- Wax
- Keratin
- Trash
- Let out
How fast rubbish builds up affects how often it happens.
Ear medicine applied topically
If inflammation or infection is present, the ENT specialist may prescribe appropriate ear drops.
Never use over-the-counter ear drops without consulting a doctor, especially if you have had ear surgery or have a perforation.
Management of concurrent illness
The doctor may also need to handle:
- Persistent infection
- Infection caused by fungi
- Skin irritation
- Allergies
- Middle-ear disorder
Certain holes can be controlled with medical care. However, structural issues often call for a different strategy.
8. When Is Revision Mastoid Surgery Needed?
A cavity may be considered for revision surgery if it is still a problem after undergoing proper medical care.
Possible indicators include:
- Discharge that is stubborn or comes back.
- Recurrent infection.
- Cholesteatoma that is recurrent or residual
- Big troublesome hole
- Pockets that are too deep to wash
- Overhanging bones
- A elevated facial ridge.
- Restricted aperture
- Poor cavity shape
- Consistent granulation
- Serious water allergy
- Regular need for professional cleaning
The precise operation is determined by the anatomy and the underlying ailment.
Revision surgery may successfully transform many chronically draining mastoid cavities into dry, water-resistant ears, according to research on problematic mastoid cavities.
9. What is the obliteration of the mastoid cavity?
The aim of mastoid cavity removal is to reduce the size of an existing mastoid cavity and enhance its function by filling some or all of it with appropriate tissue or material.
Selected materials might include:
- Bone
- Pâté de viande
- Cartilage
- Grease
- Soft tissue or muscle
- Other reconstructive materials
The decision is made based on the patient’s anatomy, prior surgery, disease state, and the method the surgeon favors.
The primary goals are to:
- Lessen the problematic hole
- reduce the build-up of trash
- Increase water resistance
- Simplify postoperative cleaning
- Lessen Constant Discharge
- When appropriate, rebuild the anatomy
Evidence indicates that mastoid ablation can enhance quality of life in chosen individuals who suffer from persistent symptomatic cavities.
Obliteration, on the other hand, is not always necessary for all patients. Depending on the individual ear, the strategy has to be chosen.
10. What Is Meatoplasty?
Meatoplasty is a surgical procedure that reshapes and enlarges the external auditory canal’s aperture.
It can help:
- Increase access to the cavity.
- Improve airflow
- Make cleaning easier
- Reduce thin pockets
- Better drainage
Alone or in conjunction with cavity obliteration or modification, meatoplasty may be done.
The ideal surgical strategy is determined by the ear canal’s state and the cavity’s form.
11. Mastoid Obliteration vs Cavity Revision
No one procedure works best for all patients.
Cavity revisions may include:
- Eliminating leftover illness
- Eliminating unhealthy tissue
- Bone that is smoothed and causing problems
- Reducing a prominent facial ridge
- Making the cavity shape better.
- cxcRevising or carrying out a meatoplasty
Mastoid obliteration might include:
- Eradicating Illness
- Reducing the hole
- using appropriate material to fill the space
- Appropriately reconstructing a section of the ear canal
The dry-ear rate was greater in patients undergoing revision surgery for chronically draining CWD cavities who underwent mastoid obliteration with posterior canal-wall reconstruction compared to those who did not.
Simultaneously, the evidence isn’t fully consistent. There is no discernible short-term difference in quality of life or hearing between certain obliteration and meatoplasty techniques, according to further potential investigations. Therefore, the approach must be customized rather than offered as a universal answer.
12. Hearing Problems and Hearing Aids
After mastoid surgery, there are many reasons why hearing loss may occur.
It could be caused by:
- The chronic ear disease at first
- Ossicle damage
- alterations in the tympanic membrane
- Scarring in the middle ear
- Engagement of the inner ear
- Prior operation
The type and degree of hearing loss may be assessed with the use of a hearing exam.
Some people may find it beneficial to:
- Typical hearing aids
- Devices that use bone conduction
- Reconstruction of the ossicles
- Other rehabilitation options for hearing
Conventional hearing aid use might be challenging due to a continuously damp mastoid cavity. Therefore, one crucial component of audiological rehabilitation may be enhancing the health of the cavity.
13. What Is the Reason for Dizziness Following Mastoid Surgery?
Some patients who have an open mastoid cavity experience dizziness when cold air or cold water gets inside it.
Temperature-related stimulation of the balance system may be caused by this.
As a result, patients with a troublesome cavity may experience dizziness during:
- Cleaning your ears
- Shower
- Swimming
- Being exposed to chilly water
Since dizziness can be caused by reasons other than the mastoid cavity, severe or persistent dizziness needs evaluation.
14. Water Precautions and Daily Care
Special water precautions may be necessary for patients with an open mastoid cavity.
Your ENT specialist could advise you to:
- Maintain a dry ear.
- Wait until you’ve been approved to swim again.
- Keep water out of the space
- Attend cleaning appointments as planned.
- Don’t stick cotton swabs or other things in your ear.
- Only use the recommended ear medicine.
After revision surgery, the surgeon will offer specific guidelines regarding bathing, swimming, exercise, and ear protection.
15. Recovery After Revision Mastoid Surgery
The sort of surgery performed determines recovery.
Patients might have: following surgery.
- mild discomfort
- Having a full feeling in the ears.
- Transient audiological alterations
- Ear packing or dressing
- During healing, there is a moderate discharge.
Monitoring is important for the surgeon because:
- The repair of wounds
- Cavity Repair
- The healing process of the graft
- Contamination
- Residual or recurrent disease
Between patients, there is a wide range in recovery times. Your surgeon must give you customized advice on how to get back to work, exercise, swimming, and other activities.
16. When Should You Contact an ENT Specialist?
If you experience any of the following, consult your ENT expert:
- Ear discharge that persists or gets worse
- Discharge with a foul odor
- Substantial ear bleeding
- Increasing discomfort in the ears
- Fever
- New or increasing hearing loss
- facial weakness
- Dizziness that is either severe or lasts for a long time
- Recurring infections
- Increased tinnitus
- Edema around the ear
Significant pain, serious bleeding, severe vertigo, facial weakness, or any other quickly worsening symptoms need quick medical evaluation.
17. Common Questions
Is it possible for a chronic ear discharge to be caused by a mastoid cavity?
Yes. Due to infection, debris, granulation tissue, residual disease, or unfavorable cavity anatomy, an open mastoid cavity can occasionally develop chronic discharge.
Does every patient who has a mastoid cavity need more surgery?
No. Professional cleaning and proper topical care can help to manage some cavities. If a structural problem, disease, or symptoms continue, revision surgery may be necessary.
Is it possible to seal a mastoid hole?
In certain patients, obliteration and reconstruction of the mastoid may lessen or remove the problematic cavity. Which approach is ideal will vary on the individual ear.
Mastoid cavity obliteration: what is it?
It is a surgical procedure that involves lowering or filling a mastoid cavity with the proper material or tissue in order to enhance its purpose and lessen issues including discharge and debris buildup.
Is mastoid obliteration always effective?
There is no surgical procedure that can ensure success. Results are influenced by the anatomy, underlying illness, surgical method, long-term monitoring, and healing process.
Is it safe to swim following mastoid surgery?
This is dependent on the kind of surgery and whether the hole has healed. Special water precautions may be required for patients with an open cavity. Always heed the advise of your ENT physician.
Why is my ear still draining months or years after mastoidectomy?
A structural cavity problem, infection, granulation tissue, residual debris, or a residual or recurring cholesteatoma are among the possible reasons. An ENT examination is needed to identify the underlying problem.
Is hearing impacted by a mastoid cavity?
Yes. Middle-ear alterations, tympanic membrane abnormalities, or ossicular damage may be associated with hearing loss. A hearing exam can tell what kind of hearing loss you have.
Is it possible for a mastoid cavity to lead to lightheadedness?
Some patients with open cavities may experience temperature-related dizziness when cold air or water enters the cavity. Yes. If dizziness persists, you should seek medical attention.
18. Important Points to Remember
- Canal-wall-down mastoidectomy is particularly connected with a mastoid cavity.
- Cavity problems do not affect all patients.
- One of the most frequent problems is persistent discharge.
- Keratin, granulation tissue, wax, and infection might build up in the hole.
- Persistent symptoms suggest the possibility of leftover or recurring cholesteatoma.
- Professional cleaning and frequent ENT follow-up may help manage some cavities.
- When structural issues or illnesses continue, revision surgery may be necessary.
- For certain individuals with bothersome cavities, mastoid obliteration may be helpful.
- Meatal drainage, cleaning, and access can all be enhanced by a meatoplasty.
- An audiogram should be performed to check for hearing loss.
- Prompt medical assessment is necessary if symptoms get worse, if there is a lot of bleeding, facial weakness, or constant dizziness.

20. Conclusion
Typically, cavity issues can be assessed and managed methodically following mastoid surgery.
Discharge, granulation tissue, hearing issues, debris buildup, or dizziness may result from a persistent mastoid cavity. To begin, identify what makes the cavity difficult.
With expert cleaning and topical treatment, some patients get better. Revision mastoid surgery, meatoplasty, mastoid obliteration, canal-wall reconstruction, or a mix of procedures may be necessary for others.
Appropriately chosen patients can have a healthy, dry, and more manageable ear thanks to contemporary revision methods. After surgery for problematic cavities, studies have revealed a significant improvement in symptoms and quality of life.
Nevertheless, the proper course of treatment is determined by the patient’s anatomy, prior surgical procedure, hearing status, and the presence of any remaining or recurring illness.
Without proper medical guidance, avoid using ear drops or deeply cleaning a mastoid cavity. After mastoid surgery, an ENT/otologist should evaluate a patient who continues to have discharge.
