The cost of electronic nasopharyngoscopy is roughly about 500 yuan in regular tertiary hospitals, however, the cost varies greatly with the level of the hospital as well as the income disparity between the east and the west and the qualifications of the hospital as a whole. For example, some hospitals do not need to do any pre-operative checkups for electronic nasopharyngoscopy, just the cost of the nasopharyngoscopy. However, such as Beijing, Shanghai and other big cities of the regular hospital, in the electronic nasopharyngoscopy need to do pre-operative checkups, such as AIDS, syphilis, etc., and some older seniors may also need to do the cardiac aspects of the examination, so the cost of all may be about 3,000 yuan.
