Radical mastoid surgery-various aspects-
A radical mastoidectomy is a surgical operation that eliminates the affected mastoid air cells, structures of the middle ear, and at times the ear canal. It is a variant of mastoidectomy that is employed to address severe or recurring ear conditions.
What it’s utilized for
When the ear canal cannot be repaired
When the illness has infiltrated the middle ear
When alternative treatments have proven ineffective
To resolve intracranial complications arising from otitis media
What it consists of
Excising the structures of the middle ear, including the ossicles and tympanic membrane
Merging the ear canal and mastoid bone into one cavity
Widening the entrance of the ear canal
Sealing the eustachian tube with soft tissue
Potential complications
Hearing impairment
Damage to the facial nerve
Dizziness or vertigo
Alterations in taste
Brain abscess
Leakage of cerebrospinal fluid
Recovery
You may have dressings and sutures on your ear
You may experience a headache, discomfort, or numbness
Your physician might provide prescriptions for pain relief or antibiotics
The aim of the radical procedure is to transform the external auditory canal, the middle ear, the attic, the antrum, and the mastoid into one interconnected open cavity. To achieve this, the mastoid antrum is accessed, the posterior wall of the bony canal that divides the middle ear from the mastoid is taken out, along with the malleus, incus, and tympanic membrane, and subsequently the diseased granulations are eliminated, merging these areas into a single cavity. The incision behind the ear is entirely sutured closed, and the postoperative care is administered through a widened membranous external auditory meatus. The radical cavity is maintained and cleaned daily until it is dry and fully dermatized.
The close connection of the middle ear and mastoid with the facial nerve, internal ear, jugular bulb, and other intracranial structures necessitates that the surgeon possesses practical knowledge of the surgical anatomy relevant to this procedure. Its success will then rely on meticulous and precise execution of the various stages involved in its technique.
THE STEPS OF THE RADICAL OPERATION
The stages that constitute the technique of the radical operation are detailed as follows:
The mastoid incision and exposure of the cortex
Access to the mastoid antrum
Removal of the posterior wall of the bony canal
Extraction of debris from the middle ear
Initial lowering of the facial ridge
Elimination of the external attic wall
Removal of the tympanic annulus
Curettage of the Eustachian tube
Final reduction of the facial ridge and exenteration of the hypotympanic space
Lowering of the floor and the anterior wall of the canal
Examination of the radical cavity
Trimming of the flap
Closure of the wound
Mastoidectomy is a term that some of you may recognize. It refers to a surgical operation aimed at removing a portion or the entirety of the mastoid bone. The mastoid bone is a component of the temporal bone located behind the ear. This bone plays a crucial role within the inner ear. Although it is referred to as a bone, its structure is more similar to that of a sponge than the rigid nature of other bones. Mastoidectomy is generally conducted to treat a variety of ear and skull base issues, primarily to combat infections, enhance drainage, or excise tumors.
What is a Modified Radical Mastoidectomy?
Modified radical Mastoidectomy (MRM) is a surgical operation performed for specific ear issues, such as chronic ear infections, cholesteatoma (an abnormal proliferation of skin cells in the middle ear or mastoid area), or other conditions that impact the ear and adjacent structures. Compared to a traditional radical mastoidectomy, it is a more conservative approach. The aim of the procedure is to eliminate any infected or impaired tissue, enhance drainage, preserve the ear canal, and protect hearing. Continue reading for further information.
When is a Modified Radical Mastoidectomy Recommended?
A Modified Radical Mastoidectomy is suggested in the following scenarios:
Chronic Ear Infections: It is advised for chronic ear infections that do not respond to conventional treatments and risk causing complications such as damage to ear structures.
Cholesteatoma: This condition involves an abnormal proliferation of skin cells in the middle ear. It can deteriorate the underlying bone and progressively result in hearing loss.
Limited Disease Involvement: When the disease or disorder is confined to a specific area involving the mastoid bone, extensive repair will not be necessary.
Certain Pathological Conditions: In situations where the patient has distinctive pathological conditions best managed with a more conservative surgical method.
It is crucial to understand that the suggestion for a Modified Radical Mastoidectomy is determined individually, based on the specific requirements of the patient and the severity of the illness. The primary objective of the procedure is to eradicate damaged tissues, enhance drainage, and maintain hearing.
How to Prepare for a Modified Radical Mastoidectomy?
Adequate preparation prior to the surgery is essential for achieving a favorable outcome. Here are some general recommendations.
A comprehensive evaluation will be performed by your surgeon who will examine your ears and provide a detailed explanation of the procedure.
The healthcare professional will review your medical history and any existing allergies. Additionally, inform them about your current medications and supplements, if applicable.
You might need to adjust the dosage or even stop certain medications, such as blood thinners, for a short time before and after the surgery.
You will be advised to stop smoking and refrain from using alcohol, as they can hinder the healing process and elevate the chances of complications.
The surgeon will give detailed fasting guidelines for the day prior to the surgery. Ensure that you adhere to them carefully.
Be sure to arrange for assistance to drive you home during your recovery period. Additionally, get your home ready to be a comfortable environment for you to rest.
Keep in mind to communicate transparently with your healthcare team, pose any questions you might have, and follow their instructions closely to ensure a safe and effective procedure.
How is Modified Radical Mastoidectomy Performed?
The procedure includes the following steps:
Anesthesia: The procedure is carried out using local anesthesia with sedation or general anesthesia.
Positioning: You will be positioned either on your back or your side, depending on the surgeon’s preference and the specifics of your situation.
Surgical Approach: The surgeon makes an incision behind or around the ear to gain access to the mastoid bone and the ear canal. The size and location of the incision may differ based on the individual situation. The surgeon may utilize a microscope or an endoscope to obtain a clear view of the surgical area.
Removal of Diseased Tissue: The surgeon carefully extracts the infected or damaged tissue from the middle ear and mastoid region.
Reconstruction: If necessary, the surgeon may reconstruct certain ear structures using grafts or prosthetic materials to restore function and enhance hearing. In some instances, a new eardrum (tympanic membrane) may be created to replace a damaged one.
Drainage and Ventilation: The surgeon may establish a ventilation tube or insert a drainage tube to promote airflow and fluid drainage.
Closure: After completing the procedure, the surgeon will close the incision with sutures or staples.
Once the procedure is finished, you will be moved to a recovery room where you will be monitored until you are stable. Your vital signs will be checked, and you will be observed for any immediate postoperative complications.
What to Expect After the Procedure?
Most patients are discharged on the same day or after one or two days.
Some level of pain and discomfort is typical following the procedure, which can be alleviated with prescription pain medications.
Your surgeon will give specific guidance on how to care for your ear after the surgery. This may involve keeping the ear dry, avoiding water exposure, and using ear drops as instructed.
Do not put anything into your ear canal, such as cotton swabs, without your surgeon’s consent.
You will be advised to refrain from strenuous activities during the initial days. You will need to take some time off from work, which will depend on the nature of your job.
Ensure that you attend the follow-up appointments arranged by your doctor to assess the healing progress.
Your doctor will provide clear guidance on when you can resume normal activities. It is essential to closely adhere to your surgeon’s postoperative instructions and maintain open communication with your healthcare team.

During the ten years following the introduction of the radical mastoid operation by Stacke and Jänsen in 1889, the procedure was met with almost frenzied enthusiasm, resulting in a significant number of poor outcomes for patients who might have been better off without the surgery. Since that time, otologists across the globe have generally adopted a much more conservative approach. However, it now must be considered that this approach may be excessively conservative. Courville and Nielsen demonstrated in a study of 10,000 consecutive autopsies that the incidence of middle ear infection was 1. 67 percent; Kafka illustrated that from 1,125 cases of chronic mastoiditis, 7 percent experienced intracranial complications, and of those, 87 percent ended fatally. Thus, one could argue that performing surgery in cases that have already developed intracranial complications is nearly equivalent to locking the barn after the horse has been stolen.
The primary reason for undertaking the radical operation is to protect the patient’s life.
If there are no immediate severe complications, this operation can be considered for eliminating chronic, foul-smelling discharge that may be socially or economically troublesome for the patient, potentially hindering their ability to find employment. The fact that surgery is warranted in these cases is favorable, but it should not be overly emphasized if there are other more significant justifications for proceeding with the operation. As Ballance noted, “It is clear that there remains excessive reluctance in advocating surgery before the emergence of threatening symptoms. The disease itself is the basis for surgery, not the alarming symptoms of broader and deeper disease. The most genuinely conservative treatment is that which most effectively and swiftly cures the disease. ” The indications for performing the radical operation can be categorized into two primary groups. The first group includes the imperative indications, such as intracranial complications. Meningitis arising from chronic otitis media certainly serves as an indication for surgery. If surgery is conducted early during a period of potential meningitis (serous meningitis or meningismus), the likelihood of a favorable outcome is significantly greater than when full-blown meningitis is present. This latter complication almost always proves to be fatal.
When lateral sinus thrombosis occurs due to chronic otitis media, experience indicates that there is extensive bone destruction, typically affecting the tegmen antri or the tegmen tympani as well. The operation here acts as a preventive measure against further extension, potentially to the brain, as well as addressing the thrombophlebitis itself. If a brain abscess is present, it usually arises through direct extension. Consequently, the most logical method for sacral relief is through the radical operation, during which the fistulous tract will be revealed. Should a basal skull fracture involve the middle or inner ear in a patient suffering from chronic otitis media, immediate radical surgery is warranted as a fracture can pave the way for meningitis or purulent labyrinthitis.
When complicated irritation happens repeatedly during the progression of chronic medis, it typically signifies necrosis in the labyrinthine capsule, and most frequently at the horizontal canal. Either this or the indication of the presence of a labyrinthine content requires an essential recommendation for radical surgery to prevent the potential.
