OBJECTIVE: Exploring the clinical features of aviatic @entity11766 to provide references for medical evaluation, prevention and control measures in aircrew. METHOD: To analysis and summary 605 cases with 503 pilots of @entity11766 in aircrew during 1966 to 2013. RESULT: (1) There were 605 cases of aviatic @entity11766 , including 550 cases of @entity66 and 55 cases of specific diseases. The general @entity11766 included 140 cases of anatomical abnormalities in nasal cavity type, 290 cases of @entity32 in nasal cavity, 73 cases of @entity566 type, 47 cases of cyst and @entity5 type, and the specific @entity11766 were 55 cases of @entity50 ( @entity50 ). (2) The, constituent ratio of @entity50 , which was @entity1177 @entity50 , was 95.55%. (3) The constituent ratio of cyst and @entity5 type in nasal cavity was easier causing to @entity50 than anatomical abnormalities, @entity32 , @entity566 in nasal cavity (P < 0.05). (4) The grounded constituent ratio of secondary @entity50 was higher than anatomical abnormalities, @entity32 , @entity566 , cyst and @entity5 disease in nasal cavity (P < 0.05). (5) The ways of hypobaric chamber tests were different for the kinds of aircrew. The qualified adjustment function of sinuses for barometric pressure was an essential condition for aircrew to continue flying. (6) The key point for the treatment of aviatic @entity11766 was to remove pathological change in nasal cavity and @entity50 and restore @entity50 ostium patency. The key point for the medical evaluation was to restore normal @entity50 pressure balance function. CONCLUSION: The key point of medical evaluation about aviatic @entity11766 is to assess the @entity50 pressure balance function in hypobaric chamber tests. Normative treatment and medical evaluation can effectively avoid flight accidents and improve the attendance rate for aircrew.
