【摘要】 目的 :探讨综合法对正常人咽鼓管功能检测的实用性。方法 :对 30例 ( 6 0耳 )正常人分别检测静态时、捏鼻吞咽和捏鼻鼓气后的鼓室导抗图 ,其峰压点分别为 P1 、P2 和 P3,以 P1 - P2 >10 da Pa或 Pmax- Pmin>15 da Pa判断为咽鼓管功能正常。结果 :70 % ( 42 / 6 0 )的正常人咽鼓管功能正常。结论 :该法具有简单、客观和实用等优点 ;峰压点有明显移动可表明咽鼓管功能正常 ,但峰压点移动不明显尚不能完全断定咽鼓管功能不良 ,需再采用其他方法检测更多还原

【Abstract】 Objective:To study the practicality of a new method to evaluate eustachian tube funchin.Method:We acquired the tympanogram of 30 normal persons (60 cases) by means of classical tympanometery,Toynbee test and valsalva maneuvre respectively,the peak point of each tympanogram was P 1,P 2 and P 3 corresponding P 1-P 2>10 daPa or P max -P min >15 daPa was accepted as normal.Result:70% cases were accepted normal,whose peak point shifted obviously.Conclusion:The method is a simple,objective and practical one;If the peak point shifts obviously,the function of ET is normal;On the contrary,if the function of ET may be abnormal,other tests should be performed.更多还原
