Correlating the cochleovestibular deficits with tumor size of acoustic neuroma.

摘要: Conclusion. The tumor size of acoustic neuroma correlates with cochleovestibular deficits. Those tumors global frequency hearing loss, bilateral gaze nystagmus, or absent caloric and VEMP responses may indicate a >2.5 cm. Objective. This study aimed to investigate the correlation between deficits neuroma. Patients methods. A total 44 patients were enrolled in this study. Pure tone audiometry, electronystagmography, test, vestibular evoked myogenic potential (VEMP) MRI conducted. Results. There is trend audiographic configuration, small-sized normal rising types, medium-sized mid- high-frequency large-sized flat deafness types. Five nystagmus had significantly larger than those without nystagmus. When 1 0 are used represent abnormal respons...
