If tinnitus is also accompanied by hearing decline, then you must be alert to the head of the brain.

Many people have had the symptoms of tinnitus. Many people have had it. The data shows that the number of tinnitus in my country has reached 1 to 150 million, and there are tinnitus in almost ten people.

Because the cause of tinnitus involves multiple aspects, it is not easy to completely solve this problem, so many people choose to "swing bad" -

"Anyway, I can't cure it, so don't care about it, wait for it to ang!"

But Dr. West China wants to tell you that this attitude must not be, especially like this tinnitus we want to talk about below. Annoyed.

Below, Deputy Chief Physician of Lan Zhigang, a neurosurgery of Huaxi Hospital of Sichuan University, to tell you why long listening to neuroma can cause tinnitus, what symptoms will there be and how to treat neuroma.

1. What is listening to neuroma

Listening to neuroma is a common tumor in the brain. It grows in a small horn area of ​​the bridge brain. Basically, it is behind the ears. You can touch a bone bulge position. The depth is 3 ~ 5cm in this position.

Listening to neuroma often occurs among young and middle -aged people aged 30 to 50. In recent years, the incidence has continued to rise. In 1970, the incidence rate was 1 case/100,000 people, and currently 3 to 5 cases/100,000 people. Among them, people over the age of 50 have grown the most obvious, and the incidence is close to 15-20 cases/100,000 years. One out of 1,000 unilateral tinnitus cases are caused by listening to neuroma.

Second, these symptoms will occur after listening to neuroma

According to the size of the tumor, the hearing neuroma is divided into level 1-4, the level 1 listening to neuroma is early, level 2-3 is the mid-term, and level 4 is advanced.

level

Tumor diameter and location characteristics

Level 1

The tumor is limited to the inner listening path, the diameter ≤1cm

level 2

The tumor invading the horn of the bridge, the diameter ≤2cm

Level 3

The tumor occupies the corner of the bridge and compresses the brain stem, but it is not accompanied by the movement of the brain stem, the diameter is ≤3cm

level 4

Giant tumor, diameter> 3cm, accompanied by brain stem displacement or stroke water water

1

Early (level 1) listening to neuroma

The most common and earliest symptoms of neuroma are tinnitus. The tinnitus in the early stages is mostly on the side, similar to the "cicada sounds" or "whistle sound" high tone, which can last for several years, and it will not be obtained by a while and a half.

In addition to tinnitus, early hearing neuroma will also experience symptoms such as dysfunction, dizziness, nausea, standing, and unstable walking, and may even gradually deafness in the later stage. If hearing loss occurs, it will usually last for several months to several years.

2

Mid-term (level 2-3) listening to neuroma

Due to the "close relationship" of listening to the nerves and facial nerves, and trigeminal nerves, when the tumor grows, it may be pressed to the facial nerves and trigeminal nerves next to the side, and the face symptoms on the same side, such as the numbness of the face, facial muscle convulsion, facial muscles, facial muscles Atrophy, etc., in a few cases, even mild facial paralysis will occur.

3

Late (level 4 and above) listening to neuroma listening

When the advanced volume of neuroma increases, the brain stem, cerebellar and posterior brain nerves will cause hemiplegia and body sensation, cerebellar mixing, unstable gait, difficulty in pronunciation, hoarse sound, difficulty swallowing, dietary stubborn diet Cough, etc.

If tumor compression causes intracranial high pressure symptoms such as headache, vomiting, and vision loss if the tumor compression causes intracranial hypertension.

Third, this kind of tinnitus is suspected to be listening to neuroma

Tinnitus appears. Generally, everyone's response is to go to the otolaryngology specialty. If you encounter doctors with insufficient experience, then you may be misdiagnosed as neurotic tinnitus, which will easily lead to the greater and bigger tumor, becoming a huge hearing neuroma.

Therefore, if there is tinnitus, especially the persistent tinnitus of a unilateral treble, it is also accompanied by hearing decreased, dizziness, nausea, and vomiting. Do not stabilize at home. Please go to neurosurgery as soon as possible Essence

ask

"Is there a way to distinguish between listening to neuroma and neurotic tinnitus?"

Answer: After seeing the symptoms of neuroma, many friends must feel really similar to the symptoms of neurotic tinnitus.

In fact, the biggest difference between listening to neuroma tinnitus and neurotic tinnitus is that early hearing neuroma not only has tinnitus, but also reduces hearing decreased, and neurological tinnitus generally does not have to hear. In addition, the effect of tinnitus caused by neuroma is not obvious, and dizziness will occur.

Fourth, the treatment of neuroma listening to neuroma

Doctors will comprehensively consider formulating the optimal treatment plan according to factors such as the patient's situation and the size and classification of neuroma, which will include about three types.

1

Follow -up observation

In the early days of listening to neuroma, follow -up observations were performed first, and a head MRI examination was performed every 6 months. If the tumor volume is increased during the follow -up process, the treatment method is selected according to the doctor's evaluation. For example, for patients who are older and over the age of 70 and above, patients with poor systemic conditions are not tolerated, the first choice of three -dimensional orientation radiation surgery treatment.

2

Micro -surgical surgery treatment

Now listening to neuroma surgery has entered the "era of modern skull nerve function retention", which can not only remove the tumor, but also retain the cranial nerve function. It's relatively high.

Although the hearing neuroma is very mature, if it is not diagnosed in time in the early days, after the tumor grows up, the tumor's full resection rate and the reservation rate of neurological function will decrease, and the time for rehabilitation of paralysis after surgery will be prolonged. Doctors Huaxi had a follow -up rate of facial nerves and listening nerve function after surgery. After 5 years of follow -up, it was found that patients with early (level 1) reached 99%and 90%, respectively. 15%. Therefore, it is very important to discover and diagnose listening to neuroma. Patients with effective hearing in the middle -term hearing neuroma may consider adopting surgical paths that retain hearing; patients with no effective hearing neuroma, and patients with advanced listening neuroma, first -class surgical treatment.

Stereo -directional radiation surgery treatment

S three -dimensional directional radiation surgery can maximize the preservation of tissue around the tumor. In the past 50 years, the Gamma knife has developed a large development, becoming the main means of three -dimensional orientation radiation surgery. You do not need to move the knife and open mouth. You can directly focus on the tumor site to achieve non -trauma, no bleeding, no infection, no no infection, no non -no -in -law, no non -no -in -law, no non -no -in -law, no non -in -law, no no -no -no -in -law, no no -no -in -law, no no -no -in -law, no no -no -in -law, no no -no -in -law, no no -no -in -law, no no -no -in -law, no no -no -in -law, no non -in -law, no no -no -in -law. Pain treatment avoids many surgical complications and damage to skull nerve function.

But this method also has certain limitations, such as only tumors below 2cm. For large -volume tumors, the rays cannot penetrate and completely kill tumor cells. It can only delay its development. The 5 -year control rate is about 75%to 80%, and eventually it is still recurring.

On the other hand, if the treatment of the Gama knife fails, the patient will have tissue adhesion, and the difficulty of micro -surgery will increase greatly. However, for patients who are unwilling to surgery and tolerance, and patients who recur or have incomplete postoperative recurrence or incomplete postoperative surgery, gamma knives can still be selected.
