Abstract:
Objective To summarize the experiences in clinical diagnosis, treatment and medical identification of sensorineural deafness in pilots.
Methods Clinical data about 104 pilots with sensorineural deafness admitted to our hospital from January 1967 to October 2013 were analyzed.
Results Of the 104 pilots, 58 were diagnosed with binaural sensorineural deafness, 22 with left ear sensorineural deafness, and 28 with right ear sensorineural deafness, 40 were grounded, 6 were temporarily grounded, and 58 were qualified to continue their flight. The average age of the grounded, temporarily ground and qualified pilots was 36.08±6.22 years, 35.50± 5.96 years and 35.79± 8.07 years, respectively. The average flight time of them was 1 650.72±1 026.99 h, 2 016.67±936.84 h and 1 810.43±1 230.92 h, respectively. The average auditory threshold tested by 500 Hz, 1 000 Hz, 2 000 Hz and 3 000 Hz was significantly different in the pilots grounded due to binaural hearing loss, simple left or right ear hearing loss (
P< 0.05).
Conclusion Hearing loss endangers the flight safety because it affects the communication during flight. The hearing identification standards for military pilots in China are scientific and rational. The identification principles for sensorineural deafness will be more effective with the improved hearing detection methods.
