title: [Study on anatomic measurement of oropharynx dimensions between OSAHS and the healthy adults].
abstract: OBJECTIVE
  One was to study on anatomic measurement of oropharynx dimensions between OSAHS and healthy adults, the other was to determine the normal value range of the healthy adults oropharyngeal cavity.
  
  
  METHODS
  Six anatomic measurement of oropharynx dimensions were were measured among 200 healthy adults and 93 adult patients with OSAHS,and were compared with that of healthy adults, and to determine the normal value range of healthy adults oropharyngeal cavity.
  
  
  RESULTS
  The oropharyngeal cavity size of OSAHS patients and healthy adults were significantly different, P <0. 01.
  
  
  CONCLUSIONS
  Nearly all OSAHS patients have anatomic obstructive factors at oropharyngeal cavity, The normal valve range of the oropharynx size can help to judge the oropharyngeal obstruction of OSAHS patients, and to provide the standard date for the operation of UPPP.
