【 摘 要 】

INTRODUCTION: The authors evaluate the minimum cross-sectional area (MCA) and nasal volume (NV) of the nasal cavity and nasopharynx before and after adenoidectomy. STUDY DESIGN: Clinical prospective.AIM: Evaluate changes of nasal cavity and nasopharynx before and after adenoidectomy using objective technique for assessment the nasal patency, acoustic rhinometry. MATERIAL AND METHOD: Twenty-three children (52 nasal cavities) with surgical indication for adenoidectomy were evaluated with acoustic rhinometry before and 15 days after surgery. RESULTS: The MCA of nasal cavity changed, before decongestion, from 0,73 cm2 preoperatively into 0,79 cm2 postoperatively and after decongestion, from 0,87 cm2 preoperatively into 0,93 cm2 postoperatively. The volume of nasal cavity changed, before decongestion, from 6,18 cm3 preoperatively into 6,47 cm3 postoperatively and after decongestion, from 8,31 cm3 preoperatively into 8,65 cm3 postoperatively. The MCA of nasopharynx changed, before decongestion, from 2,43 cm2 preoperatively into 2,69 cm2 postoperatively and after decongestion, from 2,76 cm2 preoperatively into 3,79 cm2 postoperatively. The volume of nasopharynx changed, before decongestion, from 5,57 cm3 preoperatively into 6,14 cm3 postoperatively and after decongestion, from 6,51 cm3 preoperatively into 8,78 cm3 postoperatively. CONCLUSION: The increase of MCA and volume of the nasopharynx agree with the improvement of the symptoms that patients or parents reported after adenoidectomy.
