24 patients with complete tympanal atelectasis were followed up for at least 7 years after tympanoplasty. The operation was done by the intact canal technique, the eardrum and ossicles were reconstructed. In 10 of the 24 patients the tympanic membrane remained intact and the tympanUM was aerated for over 7 years; in 8 patients postoperative retraction of the tympanic membrane was prevented by grommets. Atelectasis recurred in the remaining 6 patients. Even in normal tube function and normal middle ear pressure these recurrences may develop. In these cases histological studies have shown a change in eardrum elasticity. In most of the cases followed up, social hearing was sufficient for more than 7 years. Even though the long-term results of the operation are satisfactory, when tympanoplasty is indicated it must be kept in mind that there is a high percentage of recurrence in all patients, even in those with normal tube function. A prerequisite for long-term success is that the patient accepts follow-up observation for a matter of years. Otherwise therapeutic alternatives to tympanoplasty (e.g. tympanoplasty of Type IV) must be considered.
24例全鼓膜内陷患者在鼓室成形术后至少随访7年。手术采用完整外耳道技术，重建鼓膜和听小骨。24例患者中有10例鼓膜保持完整，鼓室通气超过7年；8例患者通过鼓膜切开置管防止了术后鼓膜回缩。其余6例患者内陷复发。即使在咽鼓管功能正常和中耳压力正常的情况下，这些复发仍可能发生。在这些病例中，组织学研究显示鼓膜弹性发生了变化。在大多数随访病例中，社交听力在7年以上都足够。尽管手术的长期效果令人满意，但在进行鼓室成形术时必须记住，所有患者的复发率都很高，即使是咽鼓管功能正常的患者。长期成功的一个先决条件是患者接受数年的随访观察。否则，必须考虑鼓室成形术的替代治疗方法（如IV型鼓室成形术）。
