Evaluation of Middle Ear Function by Tympanometry and the Influence of Lower Barometric Pressure at High Altitude.

abstract：:Chronic mountain sickness (CMS) and high altitude pulmonary edema (HAPE) each occur rarely in Tibetans, and they have previously not been reported in the same person. Here we describe a 37-year-old native Tibetan man with CMS at 4300 m, who developed HAPE after his return home from a 12-day visit to sea level. Possibl...
