| Abstract: | Objective: To study the relationship between the size of pontocerebellar angle tumor and audiology. Methods: Retrospective
analysis of accoustically evoked brainstem response (ABR) waveforms and pure tone threshold in 27 subjects with tumor of pontocerebellar
angle. Results: ABR wave forms and pure tone threshold were significantly affected statistically by the size of tumors, especially
those tumor larger than 3 cm in diameter. Conclusion: The primary symptom of the patient was unilateral hearing loss. Early
discovery of the lesion is important and ABR is a sensitive tool for early diagnose of the tumor. |
