Myringotomy

What the Operation Is

A myringotomy is when a small incision is made in the tympanic membrane (eardrum). It allows us to test whether ventilating the middle ear with a grommet would be of any benefit in patients with ongoing Eustachian tube dysfunction, blocked or muffled hearing, or recurrent ear pressure symptoms. The beneficial effect of a myringotomy on its own lasts approximately two to three days as the incision heals naturally, after which the original symptoms typically recur.

If the patient experiences a clear improvement during that brief window, this strongly suggests that grommet insertion is likely to provide longer-term symptom relief. If there is no benefit, the underlying cause of the symptoms is unlikely to be relieved by ventilation alone, and other treatments should be considered.

Risks & Complications

• Bleeding — a very small amount from the cut edge of the eardrum, normally settles within minutes.
• Pain — usually minimal under general anaesthetic; under local anaesthetic the only discomfort is the anaesthetic injection.
• Infection — uncommon. Watery or pus-like discharge from the ear in the first week may indicate infection.
• Other — officially all the risks of grommet insertion apply (see the grommet insertion consent page) but they are so unlikely after a simple myringotomy that they are not usually discussed.

Aftercare

• Keep the ear dry for the first 48 hours.
• Notice and remember any changes in hearing or ear pressure over the next two to three days — this is the key data we are looking for.
• Painkillers are rarely needed.
• Plan a follow-up appointment to discuss what to do next based on your response.
