Since good ventilation of the middle ear is a pre-requisite for successful myringoplasty, it was our policy to investigate the tubal function in dry central perforation of the eardrum and to correlate the manometric and endoscopic findings. Nasal endoscopy proved to be indispensable in diagnosing mechanical tubal obstruction and in localizing and even treating 'hidden' lesions in key areas, with probable normalization of the tubal function. The correction of the mechanical tubal obstruction must precede ear surgery. Whenever tubal obstruction is diagnosed as functional or idiopathic, the ventilation of the middle ear should be guaranteed during ear surgery by addition of a tympanostomy tube to the graft or drum remnant, and a guarded prognosis given.
由于中耳良好的通气是成功鼓膜成形术的前提条件，我们的策略是研究鼓膜干性中央穿孔时的咽鼓管功能，并将压力测量结果与内镜检查结果相关联。鼻内镜检查在诊断机械性咽鼓管阻塞、定位甚至治疗关键区域的“隐匿性”病变以及使咽鼓管功能可能恢复正常方面被证明是不可或缺的。机械性咽鼓管阻塞的矫正必须在耳部手术之前进行。每当诊断咽鼓管阻塞为功能性或特发性时，应在耳部手术期间通过在移植物或鼓膜残片上加置鼓膜造孔管来保证中耳通气，并给出谨慎的预后判断。
