Hearing aids are sometimes recommended in ears with tympanic membrane perforation. Presented are six illustrative cases that represent various degrees of perforation, ear-mold styles, and wearing habits. The degrees of perforation represented include total, 50%, 20%, myringotomy tube, and modified mastoid cavity (canal up). Patients wearing earmolds with total perforation experience nearly constant irritation, infection, itching, or drainage. Rare periods of success are achieved in such cases by strict adherence to hygiene and ventilation guidelines. Lesser degrees of perforation usually experience significantly fewer problems if such guidelines are followed. Ear ventilation is found to be the primary success factor, whether achieved by periods of non-use or earmold venting. Since the potential for serious complications always exists, such fittings require patient education and regular otologic follow-up.
鼓膜穿孔的耳朵有时会被推荐使用助听器。本文展示了六个具有代表性的案例，这些案例呈现了不同程度的穿孔、耳模样式和佩戴习惯。所呈现的穿孔程度包括完全穿孔、50%穿孔、20%穿孔、鼓膜切开置管以及改良乳突腔（外耳道上壁保留）。佩戴全穿孔耳模的患者几乎经常会感到刺激、感染、瘙痒或有分泌物。在这种情况下，通过严格遵守卫生和通风指南，偶尔能取得成功。如果遵循这些指南，穿孔程度较轻的情况通常问题会少得多。发现耳部通气是主要的成功因素，无论是通过不使用助听器的时间段还是耳模通气来实现。由于严重并发症的可能性始终存在，这种适配需要对患者进行教育并定期进行耳科随访。
