负压型鼓室压图是由于咽鼓管障碍导致中耳负压引起,临床该图形多见于分泌性中耳炎。目前,国内学者对负压型鼓室压图与鼓室积液的临床联系仍存有分歧。本文综合近年来有关负压型鼓室压图的鼓室峰压、镫骨肌声反射、鼓室图宽度及多频率鼓室导抗测试等多项声阻抗指标,试图探讨负压型鼓室压图与中耳积液的内在联系。 Negative pressure tympanogram is due to eustachian tube disorder caused by the negative pressure caused by the middle ear, the more common clinical patterns of secretory otitis media. At present, domestic scholars on the negative pressure tympanogram and tympanic fluid clinical relationship still exist differences. In this paper, we summarize many acoustic impedance indexes of tympanogram, tympanic muscle acoustic reflection, tympanogram width and multi-frequency tympanometry in negative pressure tympanogram in recent years, Internal contact of effusion.
