单侧耳鸣，别大意！可能是这类肿瘤的前期症状

Core Viewpoint - The article emphasizes the importance of recognizing tinnitus as a potential warning sign of serious health issues, particularly acoustic neuroma, which can lead to severe symptoms if not diagnosed and treated promptly [1][4][5]. Group 1: Acoustic Neuroma Overview - Acoustic neuroma is a common benign intracranial tumor that typically affects individuals aged 30-50 years and grows slowly, often leading to misdiagnosis due to non-specific early symptoms [4]. - Tinnitus is the most common early symptom of acoustic neuroma, often perceived as a single-sided, persistent sound similar to cicadas or electrical noise [5]. Group 2: Symptoms and Risks - As the tumor grows, it can compress the auditory nerve, leading to hearing loss, and if it affects the facial nerve, it may cause facial numbness, spasms, or paralysis. Compression of the vestibular nerve or brainstem can result in unsteadiness, dizziness, headaches, and nausea [5][6]. - Many patients have been diagnosed with acoustic neuroma only after presenting with tinnitus or hearing loss, often when the tumor has reached a significant size, making complete recovery of hearing difficult even after surgical removal [5]. Group 3: Diagnosis and Treatment - Diagnosis of acoustic neuroma primarily involves hearing tests, CT scans, and MRI to identify any space-occupying lesions in the internal auditory canal, which is crucial for early detection [6]. - Early detection and diagnosis can lead to more timely and effective treatment options. Treatment plans are individualized based on tumor size, patient age, and hearing status, with early-stage patients possibly undergoing observation, while later-stage patients may require surgical intervention or stereotactic radiation therapy [6].
