Ms. Lin, 45, recently changed two cell phones in a row, the two different brands of cell phones she felt that there were “problems”: she could not always hear each other’s speech. Once, Ms. Wang, who is usually used to answering the phone with her right hand, answered the phone with her left hand and felt that the sound quality was very good. That’s when she realized she might have an ear problem. ”Since I can’t hear well, I should go to the ear, nose and throat department to see a doctor.” But after Ms. Lin went to the hospital’s ENT department for an examination, the doctor told her there was nothing wrong with her ear and suggested she go to the neurosurgery department for another detailed examination. She underwent a hearing, evoked potential and MRI examination in the neurosurgery department of the hospital, and finally found out that the “culprit” of her hearing loss was an intracranial auditory neuroma. The doctor performed a craniotomy to remove the auditory neuroma. After the surgery, Ms. Lin’s hearing did not improve, but the surgery prevented the tumor from growing and prevented more serious consequences such as facial palsy and hemiparesis. The neurosurgeon at Beijing Hospital said that people usually think that tumors growing in the brain must be serious, but the common auditory neuroma in neurosurgery has a mild “veneer” that is easily overlooked or misdiagnosed. Many patients who suffer from early hearing neuroma think they are suffering from senile deafness and do not pay enough attention to it, and only visit neurosurgery when the tumor grows up and causes serious symptoms. Even if microsurgery is performed, the tumor will not be cured, and serious complications such as facial palsy, swallowing difficulties and limb movement disorders may remain. Doctors remind middle-aged people with tinnitus and hearing loss not to ignore these seemingly non-serious symptoms, but to consult a professional neurosurgeon to investigate and confirm the diagnosis so as not to delay treatment. Once the diagnosis of auditory neuroma is made, it should be treated early. Doctors say that although the development of auditory neuroma is slow, the auditory nerve is adjacent to the brainstem and important nerves in the brain, and as the tumor grows, it will lead to hearing loss and eventually loss of hearing; if the disease continues to develop, the tumor will compress the brainstem, cerebellum and surrounding cranial nerves, which will lead to obvious headache, vomiting, unstable walking, facial numbness and other neurological symptoms and signs, and even brain herniation, threatening the patient’s life. ”Don’t get too nervous about having an auditory neuroma.” Feng Enshan said, with the development of modern microscopic neurosurgery, the introduction of minimally invasive concept and the application of intraoperative electrophysiological monitoring technology, now the surgery of auditory neuroma has completely changed the purpose of the previous “life preservation”, neurosurgery has been able to achieve complete excision of the tumor and complete preservation of the facial nerve, and some patients diagnosed early can even be better Some patients with early diagnosis can even retain their hearing.
