What is middle ear infiltration?
This is a traditional treatment that has been long used in clinical practice and has proven to be effective in the treatment of certain ear-related pathologies.
It involves the injection of corticosteroids directly into the eardrum, i.e. an inter-tympanic intervention is performed with local and topical anesthesia so that the medication has a faster effect on the organ.
The middle ear infiltration technique allows the drugs to enter the organ with a systemic and direct diffusion, which amplifies the effectiveness of the treatment. This also allows the physician to offer an effective, safe and outpatient solution to the patient.


When is an intratimpanic injection needed?
This treatment is recommended for the following diseases:
- Acoustic trauma.
- Sudden hearing loss.
- Autoimmune disease of the inner ear.
- Tinnitus
- Menère’s disease.
Note that only an experienced otolaryngologist is able to prescribe this treatment, as well as apply it, after a physical evaluation with hearing and vestibular tests that will help to verify the diagnosis and define the treatment.
See an otolaryngologist you trust if you need to improve your hearing condition.
Preparing for Intratympanic corticosteroids
The patient does not require any prior preparation as this is an outpatient process.
However, be aware that the process of the intratympanic injection consists of:
Lying on your side on a stretcher inside the office, receiving local or topical anesthesia over the tympanum. Afterwards, with the help of a microscope, the otolaryngologist will proceed to make the injection through the tympanic membrane with the specified medication.
Once the medication has been applied, the doctor may ask you to remain in the same position, without swallowing saliva, for a period of 10 minutes.
Once the time is over, the patient will be able to continue with their normal. However, in some cases, the following sensations may be felt:
- Dizziness after the treatment.
- Ear pain.
- Burning or stinging in the area.
- Bubbling sensation in the ear.

Frequently asked questions.
Is middle ear infiltration painful?
Prior to the treatment, the doctor will apply local anesthesia and, therefore, the patient will not feel pain. In very rare cases, discomfort or pain may be felt after the application of the treatment, although these are isolated cases.
How long after the treatment will the results be achieved?
The effects of this treatment will depend on each patient and the recommendation of your doctor. Some guidelines state that consecutive injections can be done, while others recommend a period of days or weeks between each treatment.
Whichever option is most convenient for your case, it will achieve the same result: a long-term improvement of the treated condition.
Consult with your doctor how many sessions and in which periods he/she recommends them so that you have an estimate of the time in which you will notice changes and improvement in your condition.
Are there any side effects in middle ear infiltration?
Ear infiltration or intratympanic injection is a safe treatment whose effectiveness has been proven over the years. However, there is a minimal margin of risk of permanent eardrum perforation.
