飞行员前庭下神经炎一例

INFERIOR VESTIBULAR NEURITIS IN FIGHTER PILOT:1 CASE REPORT

飞行员的空间定向障碍是引起许多致命性飞行事故的首要原因。空间定向是本体、前庭和视觉输入整合的结果。前庭神经炎（VN）可能导致飞行员突然的空中失能。VN一般通过单侧冷热反应丧失所显示的前庭功能丧失表现得到诊断。但是冷热试验只测试前庭上神经的功能，单纯前庭下神经受损的患者可能会漏诊。我们报告了一个海军飞行员病例，其症状显示是前庭神经炎，但冷热试验正常，而单侧前庭诱发肌源性电位（VEMP）缺失，我们认为该飞行员患有单纯的前庭下神经炎。

Pilot spatial disorientation is a leading factor contributing to many fatal flying accidents. Spatial orientation is the product of integrative inputs from the proprioceptive, vestibular, and visual systems. Vestibular neuritis（VN） might lead to sudden pilot incapacitation in flight. VN is commonly diagnosed by demonstration of unilateral vestibular failure, as unilateral loss of caloric response. As this test reflects the function of the superior part of the vestibular nerve only, cases of pure inferior nerve neuritis will be lost.
