Acoustic neuroma symptoms?
summary
Acoustic neuroma is a benign tumor originated from the acoustic nerve sheath. It is one of the common intracranial tumors, accounting for 7% - 12% of intracranial tumors and 80% - 95% of cerebellopontine angle tumors. Most of them are adults, with the peak age of 30-50 years old. The cases under 20 years old are rare. Single acoustic neuroma in children is very rare. There was no significant gender difference. The incidence of left and right is similar, occasionally bilateral. Acoustic neuroma symptoms? Let's talk about it
Acoustic neuroma symptoms?
When the tumor volume was small, there were tinnitus, hearing loss and vertigo on one side, and a few patients had deafness after a little longer time. Tinnitus can be accompanied by paroxysmal vertigo or nausea and vomiting.
When the tumor continued to expand, it compressed the ipsilateral facial nerve and trigeminal nerve, and there were convulsions of facial muscles and decreased secretion of lacrimal gland, or mild peripheral facial paralysis. Trigeminal nerve damage showed facial numbness, pain, tactile decline, corneal reflex weakening, temporalis and masticatory muscle weakness or muscle atrophy.
When the tumor volume is large, it oppresses the brainstem, cerebellum and posterior cranial nerves, causing crossed hemiplegia and hemisensory disturbance, cerebellar ataxia, gait instability, dysphonia, hoarseness, dysphagia, diet cough, etc. The occurrence of cerebrospinal fluid circulation obstruction included headache, vomiting, vision loss, papilledema or secondary optic atrophy.
matters needing attention
Acoustic neuroma is a benign tumor, if the tumor can cause serious hearing loss, facial paralysis before surgery, the effect is good, so early diagnosis is the key. First of all, we should strengthen the propaganda of popular science knowledge about acoustic neuroma, so that people can increase their understanding of acoustic neuroma, identify its early symptoms, enhance their vigilance and check it as soon as possible.
