When it comes to acoustic neuroma, people will think that this kind of tumor grows in the brain, and once it develops, it must be very serious. In fact, it is not, the disease of acoustic neuroma starts calmly and slowly, the initial symptoms – tinnitus, face numbness and so on, but the bad thing is that acoustic neuroma is very easy to be misdiagnosed or underdiagnosed. Early manifestation of acoustic neuroma is mainly unilateral, persistent, persistent tinnitus, and the treatment effect is not obvious, and hearing loss in the long run. This is a symptom of irritation caused by the tumor pressing on the nerve, and it is difficult to distinguish it from ordinary tinnitus. Therefore, many patients with acoustic neuroma who go to the ENT department in the early stage cannot find out the cause of the disease, and are considered to be general hearing loss, or senile deafness.” Early-stage patients, especially middle-aged individuals with unilateral tinnitus, should consider the possibility of an acoustic neuroma. Early treatment has a high rate of not only facial nerve preservation, but also the potential for hearing preservation. Imaging is developing relatively rapidly, and CT and MRI techniques in particular have become reliable means of diagnosing acoustic neuromas. Of course, middle-aged patients with persistent tinnitus do not have to go for CT or MRI right away, but can be tested for auditory conduction function first. This test is more economical, and further testing can be done if problems are found. The majority of auditory neuromas occur unilaterally. Although it develops slowly, it is adjacent to the brainstem and cerebral nerves, and as the tumor increases in size, it will lead to hearing loss, and eventually loss of hearing; it will also show symptoms of brainstem or local cranial nerve invasion, such as dizziness, facial numbness, facial paralysis, cough weakness, difficulty in swallowing, and unsteady gait. Further development of the tumor may cause hydrocephalus, and once the intracranial pressure increases, it will lead to worsening headache, vomiting, vision loss, and even brain hernia, threatening the patient’s life. Currently, the ideal treatment goal is total resection of the tumor with preservation of facial nerve and auditory nerve function. Middle-aged people with tinnitus and hearing loss, facial numbness should not ignore these seemingly minor symptoms, which may be the precursor of acoustic neuroma. If the cause of tinnitus cannot be found in ENT department and treatment is not effective, further examination should be done as early as possible. Early detection and early diagnosis will greatly improve the treatment effect of acoustic neuroma, and the retention rate of facial and auditory nerves will be improved.
