We examined the eustachian tube function of 48 patients with adhesive tympanum who had undergone operations. Preoperative tubal openings were observed and determined in 57% of these cases by the dynamic movement of the tympanic membrane, 35% by the impedance method, and 74% by the sonotubometry and was found to be lower than in healthy subject. Furthermore the tubal opening duration in sonotubometry was significantly shortened in patients with adhesive tympanum as compared to healthy subjects. However, in a few cases of adhesive tympanum, tubal opening was prolonged remarkably, and indicated a mixed tendency of stenotic and patulous types. Postoperative tubal opening was not seen in 90.9% of the cases as determined by the inflation-deflation test. Mucociliary function was poor in 81.3% of the cases. No remarkable differences were seen between cases of total adhesion and those of posterosuperior quadrant adhesion by any method. The condition of the tympanic membrane and the tympanic cavity after operation, and the eustachian tube function were not correlated in some cases and indicated possible involvement of other factors.
我们检查了48例接受过手术的粘连性中耳炎患者的咽鼓管功能。术前，通过鼓膜动态运动在57%的病例中观察并确定了咽鼓管开口，通过阻抗法在35%的病例中确定，通过声导抗测管法在74%的病例中确定，结果发现其低于健康受试者。此外，与健康受试者相比，粘连性中耳炎患者声导抗测管法中的咽鼓管开口持续时间显著缩短。然而，在少数粘连性中耳炎病例中，咽鼓管开口明显延长，呈现出狭窄型和开放型的混合趋势。通过充放气试验确定，90.9%的病例术后未见咽鼓管开口。81.3%的病例黏液纤毛功能较差。通过任何方法，全粘连病例和后上象限粘连病例之间均未观察到显著差异。术后鼓膜和鼓室的情况与咽鼓管功能在某些病例中无相关性，提示可能涉及其他因素。
