Hello, I’m Dr. Shree Rao. Throughout my clinical practice, I have encountered patients with questions and uncertainties about surgical procedures, such as types of eardrum surgery. I empathize with these concerns and believe that informed patients feel more confident and comfortable in their treatment journey.
One of the most common areas of concern I encounter relates to problems involving the eardrum. The eardrum, a thin and delicate piece of tissue located within the ear, plays a key role in hearing by transferring sound vibrations from the outer ear to the middle ear. When the eardrum is impaired due to infection, injury, loud noise exposure, or long-standing ear disease, hearing loss and persistent ear discharge may occur. The body’s healing capacity may be insufficient. If medications do not resolve the ear condition, surgery may be necessary. The kind of surgery required will be decided based on an assessment of the overall ear condition.
In this blog, we will focus on types of eardrum surgeries, viz. Myringoplasty, Myringotomy, Tympanoplasty, and explain when each may be essential.
Myringoplasty
Myringoplasty is a surgery particularly targeted to repair a hole (perforation) in the eardrum. Medically, it is classified as a ‘Type I Tympanoplasty’, where only the eardrum is repaired without involving the middle ear bones. The surgeon patches a hole using a graft. It is a minimally invasive procedure with a success rate of over 85%.
When is it needed?
Eardrum perforations often heal within days or weeks. However, surgery is advised if
- The tympanic membrane perforation persists for more than three months.
- When the patient experiences repeated infections caused by water entering the middle ear through the perforation
- There is observable hearing loss due to the perforation.
Myringotomy
In Myringotomy, the surgeon makes a tiny incision in the eardrum to remove pressure or drain fluid, such as fluid or pus. Based on the patient’s condition, a grommet – a tiny ventilation tube – may be used. It is placed into the slit to keep the middle ear aerated and avoid fluid from reaccumulating. The incision heals by itself, and the tube usually falls out naturally after 6 to 12 months. Typically, this operation takes about 20 minutes, done under local anaesthesia for adults and general anaesthesia for children. Myringotomy can be carried out via laser in selected cases.
When is it needed?
The patient may need a myringotomy if:
- Fluid persists in the middle ear for several months, resulting in hearing loss.
- Recurrent ear infections occur, typically 3–4 times per year.
- Severe pain develops due to changes in air pressure.

Tympanoplasty
Tympanoplasty is a form of surgery that involves repairing the eardrum and examining or rebuilding the middle ear. It is categorized into five types depending on the intensity of the damage. For instance, Type I involves repairing the eardrum alone, and Type III involves positioning the eardrum graft onto the stapes as other hearing bones (ossicles) are missing or impaired. The success rate of Tympanoplasty is over 90%.
When is it needed?
Tympanoplasty is vital for more complicated cases. These may be due to:
- Large perforations that cannot be patched.
- Chronic Suppurative Otitis Media (CSOM) – a prolonged infection responsible for uninterrupted discharge.
- Cholesteatoma – an abnormal skin growth behind the eardrum that can wear away the bone.
- Middle ear damage.

Factors Doctors Use to Determine the Right Surgery
The doctor assesses the:
- Size and location of the eardrum perforation
- Hearing test results – Visual Reinforcement Audiometry (VRA), Pure Tone Audiometry, Tympanometry, and Acoustic Reflex Measures / Middle Ear Muscle Reflex (MEMR)
- Presence of infection or discharge
- Condition of the middle-ear bones
- CT scan findings (as desired)
Based on the above findings and readings, the most appropriate surgery is selected.
Conclusion
Eardrum problems can significantly impact hearing and quality of life, but modern surgical options like Myringoplasty, Myringotomy, and Tympanoplasty offer effective solutions tailored to each patient’s condition. The choice of surgery depends on factors such as perforation size, middle-ear health, presence of infection, and hearing test results, ensuring a personalized approach. Consulting an experienced ENT specialist helps patients understand their options, make informed decisions, and achieve the best possible outcomes for long-term ear health.
