If it comes to a bang trauma, it is an acoustic Trauma. This happens when the hair cells in the inner ear are damaged. This happens when an increased sound pressure affects the ear. As soon as a certain threshold is exceeded by this pressure, it is no longer possible for the human ear to adapt. There is damage. In most cases, there is a bang trauma when the damaging sound acts relatively briefly between one and two ms.
We have summarized all interesting information on the topic of trauma for you here. If you are interested in the causes and symptoms of this, you are exactly right here with us. We explain to you how your doctor makes the diagnosis of a blast trauma and which therapy approaches are possible. If you have any questions, we are happy to be at your disposal without obligation and free of charge.
Can a hearing aid help with a blast trauma?
If a blast trauma persists and persists, hearing loss in the high frequency range occurs in most cases. This hearing impairment can be caused by a Hearing very well-balanced. This will improve your quality of life, you will be able to hear better again, especially in noisy environments, and you will perceive sounds that you can no longer hear through the hearing aids.
Reasons and causes for a blast trauma
The reasons for acoustic trauma can be different. Typical examples include:
- A powerful blow to your ear
- Lightning strike
- Blowing up
There is a disturbance in the metabolism of your hair cells. The oxygen supply is no longer sufficient and free radicals can no longer be formed. Mechanical damage is also possible. First of all, the basal area of the auger is affected, which also includes the high-pitched area.
What symptoms arise from a blast trauma?
A typical symptom of a blast trauma is the feeling that your ear is clogged, and you also notice a Hearing on the affected ear. Typical other symptoms of trauma are::
Usually only one side is affected by a blast trauma. In the first days, the symptoms improve. A progression of symptoms is generally not to be expected.
What to do when diagnosing trauma?
For a diagnosis your throat nose ears doctor creates a Hearing curve. This audiogram can be used to detect hearing loss. Either a sink is detected at 4000 Hz or a drop of the curve at high sound frequencies.
With a blast trauma, the so-called Sisi Test turns out positive. For you, it means that the range between the comfort threshold and the hearing threshold is less than in people who can hear normally. The loudness itself increases faster. This is done by the damaged outer hair cells. In a healthy ear, the outer hair cells can modify the sound. Quiet tones are amplified, or loud tones are attenuated. This usually allows you to perceive a relatively wide range of tones.
However, if your hair cells in your ears are damaged, this modification fails. The reason can be a blast trauma. No otoacoustic emissions can then be measured. This only works if the outer hair cells are intact. However, because this Test results in additional noise pollution, it is only carried out one week after the Trauma.
What therapy options are there in case of bang trauma?
The first therapeutic measure is an infusion therapy with procaine and HAAES. The treatment is almost similar to that of a Hearing loss. Furthermore, cortisone may still be administered. If these two therapies do not work, hyperbaric oxygen therapy is attempted.
In any case, you should start therapy as early as possible, because this is crucial for the prognosis. The earlier you start the therapy, the lower the risk that you will suffer permanent damage from the blast trauma.
Operations are only performed if either one or both windows in the inner ear are damaged or a Perilympfistula has formed. In this case, a pathological connection to the middle ear arises. A possibly existing fistula or a damaged window is achieved by a renovation of the eardrum opening. There is talk of the so-called Tympanotomy.
If the Trauma lasts longer with you, it usually comes to a hearing damage in the high-pitched area. Especially in a louder environment you will feel restricted. A hearing aid can help you with a permanent bang trauma in any case, so that you can also perceive the high tones again.
What prognosis is there for a bang trauma?
The prognosis is relatively good. After about six weeks, you can expect an improvement in the symptoms. Often the hearing restores itself completely. However, if the symptoms still persist after six weeks, your prognosis looks rather poor. In most cases, you can no longer expect a successful therapy.
