Tympanic membrane perforation: understanding the causes, diagnosis and treatment
The tympanic membrane, also known as the eardrum, is a delicate and important structure within the ear that separates the outer ear from the middle ear. When the eardrum is perforated or ruptured, it can result in a range of symptoms including hearing loss, pain, and even infection. If you suspect that you have a perforated eardrum, it is important to seek the advice of an experienced Audiologist for an accurate diagnosis and effective treatment.
There are many different causes of a perforated eardrum, some of which include:
Trauma: A sudden impact or blow to the ear can cause the eardrum to rupture, such as a blow to the head, loud explosion or other loud noise exposure.
Infection: A middle ear infection can cause the eardrum to become inflamed and eventually burst.
Barotrauma: This occurs when the pressure difference between the outside and inside of the eardrum becomes too great. This can happen during air travel, diving or other activities where the air pressure changes rapidly.
Foreign object: An object that enters the ear canal can puncture the eardrum, such as a cotton swab or hairpin.
Eustachian tube dysfunction: This is when the tubes that connect the middle ear to the back of the throat become blocked, leading to a build-up of pressure and the potential for the eardrum to burst.
Diagnosis of Tympanic membrane perforation
Diagnosing a perforated eardrum is typically a straightforward process. Your Audiologist will carry out a thorough examination of your ear, including a visual inspection of the eardrum using an otoscope. They will also carry out a diagnostic hearing assessment to understand the level of hearing loss, as well as other tests to rule out any underlying conditions.
Treatment and management of tympanic membrane perforation
The treatment and management of a perforated eardrum will depend on the cause, the size and location of the perforation, and the overall health of the individual.
In some cases, small perforations may heal on their own without the need for treatment. Your Audiologist may advise that you avoid activities that could cause further damage, such as swimming, and to keep the ear dry.
For larger perforations or those that are not healing a referral to an ear, nose and throat (ENT) specialist may be required. Treatment includes medication or surgery may be recommended. This will typically involve the placement of a small patch over the perforation to help it heal. In some cases, a more extensive procedure may be required to repair the eardrum.
A successful outcome from treatment for a perforated eardrum will depend on the individual case, but generally speaking, most people can expect a full recovery. This will typically involve a reduction in pain and an improvement in hearing. Your Audiologist will monitor your progress and provide advice on the best course of action to ensure the best possible outcome.
A perforated eardrum can be a painful and disruptive condition, but with the right diagnosis and treatment, it is possible to make a full recovery. If you suspect that you have a perforated eardrum, or are experiencing any symptoms that concern you, it is important to seek the advice of an experienced Audiologist for an accurate diagnosis and effective treatment and management.
