This propsective study analyses the role of blink reflex (BR) in 75 patients with Cerebellopontine Angle (CPA) tumours. The aim was to find out the subclinical involvement from the blink reflex findings. Fifth nerve was clinically involved in 82.7% patients while, BR was able to detect afferent abnormality only in 54% patients. The seventh nerve was clinically involved in 74.7% and blink reflex could detect the efferent abnormality is 72% patients. Thus, clinicoelectrophysiological correlation was 56.4% and 72% for V and VII nerve respectively. In the patients in whom there was no V or VII nerve involvement BR showed VII nerve involvement in 12% patients. The subclinical involvement of the V nerve and the brainstem were detected by BR in 4% patients each. In conclusion BR is good test for the assessment of VII nerve function as compared to V nerve function. BR could pick of subclinical involvement in 20% patients.
这项前瞻性研究分析了瞬目反射（BR）在75例桥小脑角（CPA）肿瘤患者中的作用。目的是通过瞬目反射结果找出亚临床受累情况。临床上，82.7%的患者第五神经受累，而BR仅能在54%的患者中检测到传入异常。临床上，74.7%的患者第七神经受累，瞬目反射能在72%的患者中检测到传出异常。因此，V神经和VII神经的临床电生理相关性分别为56.4%和72%。在无V或VII神经受累的患者中，BR显示12%的患者VII神经受累。BR在4%的患者中检测到V神经和脑干的亚临床受累。总之，与V神经功能相比，BR是评估VII神经功能的良好测试。BR能在20%的患者中发现亚临床受累情况。
