摘要
目的比较改装体检直升机与歼击机飞行员听力学检查结果,初步了解不同机种飞行员的听力差异。方法对进行改装体检的直升机和歼击机飞行员各41名进行纯音听阈和畸变产物耳声发射检查,比较两组结果。结果根据《中国人民解放军空军飞行人员体格检查标准》,82名飞行员耳鼻咽喉专科飞行结论均为飞行合格。两组飞行员双耳0.25～8kHz平均听阈均正常,其差异无统计学意义(P>0.05);两组1～8kHz DPOAE幅值均正常,在3～4kHz,歼击机组右耳的DPOAE幅值明显低于直升机组(P<0.05);直升机组和歼击机组高频PTA异常率分别为14.63%和24.39%,两组比较差异无统计学意义(P>0.05)。直升机组和歼击机组高频DPOAE异常率分别为34.15%和58.54%,两组比较差异有统计学意义(P<0.05)。结论改装体检的直升机飞行员与歼击机飞行员的听力状况无显著差异,但歼击机飞行员高频DPOAE异常率高,潜在听力损失的可能性更大。
Objective Compare and analyze the audiology data（PTA and DPOAE） in pilots under physical examination for modification to equipment of high performance aircrafts,in order to get preliminary understanding of hearing difference of the pilots from types of aircraft.Methods We collected the audiology data of 82 pilots who accepted physical examination for modification to equipment of high performance aircraft in our hospital.Eighty-two cases were divided into two groups according to the type of aircraft（41 cases in helicopter group and 41 cases in fighter group）.We investigated the difference of PTA（250~8 kHz）and DPOAE（1~8 kHz）results between these two groups.Results All the pilots got the flying qualification for the high performance aircraft.In all the tested frequency,binaural average hearing threshold and DPOAE amplitude were within the normal range.The PTA difference between the two groups was not statistically significant.At 3 kHz and 4 kHz,the difference of right ear DPOAE amplitude between the two groups was statistically significant,but had no clinical significance.The incidence of abnormal high frequency PTA between the two groups had no statistically significant difference.But the incidence of abnormal high frequency DPOAE had statistically significant difference.There was a higher incidence of abnormal high frequency DPOAE in fighter pilots.Conclusion There were no significant differences in hearing between the helicopter and fighter pilots under physical examination for modification to equipment of high performance.But in fighter pilots more likely had potential hearing loss.This may be related to the stronger protection awareness in helicopter pilots.
