Acoustic neuroma is a noncancerous (benign) and usually slow-growing tumor that develops on the main nerve leading from your inner ear to your brain.
聽神經(jīng)瘤是一種非癌性（良性）并且通常生長緩慢的腫瘤，它發(fā)生在從內(nèi)耳到大腦的主神經(jīng)上。
Because branches of this nerve directly influence your balance and hearing, pressure from an acoustic neuroma can cause hearing loss, ringing in your ear and unsteadiness.
由于該神經(jīng)的分支直接影響平衡和聽覺，聽神經(jīng)瘤對該神經(jīng)的壓迫可導致聽覺喪失、耳鳴和不穩(wěn)定性。
Acoustic neuroma typically grows slowly or not at all, but in a few cases it may grow rapidly and become large enough to press against the brain and interfere with vital functions.
聽神經(jīng)瘤生長緩慢或者根本不生長，然而在少數(shù)病例中，該腫瘤可能生長迅速，并且可能長大到足以壓迫大腦并妨礙生理機能。
