1. Vestibular dysfunction
Compression of the vestibular nerve may cause vertigo and nausea, often worsened by head movement; vestibular rehabilitation can improve central compensation.
2. Progressive hearing loss
Compression of the cochlear nerve can lead to high-frequency hearing loss and reduced speech discrimination; in advanced stages, profound hearing loss may require auditory implantation.
3. Tinnitus and hyperacusis
Persistent high-pitched tinnitus on the affected side may be the only early symptom; some patients develop reduced tolerance to everyday sounds.
4. Facial sensory abnormalities
Tumor enlargement may compress the trigeminal nerve, causing facial numbness and reduced corneal reflex; differentiation from paroxysmal trigeminal neuralgia is required.
5. Balance impairment and ataxia
Vestibular dysfunction can cause unsteady stance, worsened in darkness; in advanced disease, cerebellar compression may produce impaired finger-to-nose testing.
6. Increased intracranial pressure
Obstruction of cerebrospinal fluid circulation may cause morning headache, vomiting, and papilledema, potentially requiring urgent surgical intervention.
7. Lower cranial nerve palsies
Inferior compression of the glossopharyngeal and vagus nerves may cause dysphagia, choking when drinking, and hoarseness, requiring rehabilitation.
8. Facial nerve dysfunction
Early compression may cause mild weakness; advanced disease may lead to mouth deviation. Intraoperative nerve monitoring can reduce the risk of injury.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that although acoustic neuroma is benign, it can cause irreversible damage. Individualized planning should integrate tumor size, hearing status, and patient age. Combined minimally invasive surgery and radiotherapy can improve outcomes. High-risk populations are advised to undergo proactive screening, and MDT-based multidisciplinary collaboration supports functional preservation and long-term survival.
