To study the effect of Silastic® sheeting placed in the middle ear during tympanoplasty, including the effect on hearing.
Retrospective study.
Chronic inflammation of the middle ear is common. Surgical treatment sometimes results in middle-ear adhesions and hearing deterioration.
We selected 106 patients with chronic otitis media, middle-ear adhesions and intact ossicles, based on intra-operative findings. These patients underwent single-stage tympanoplasty either with or without insertion of Silastic sheeting. Audiometry was undertaken pre-operatively and one and 12 months post-operatively.
Patients who had undergone Silastic sheet insertion showed significantly better air conduction, bone conduction and air-bone gap averages one year post-operatively, compared with those who had not.
研究在鼓室成形术中置于中耳的硅橡胶片的作用，包括对听力的影响。
回顾性研究。
中耳慢性炎症很常见。手术治疗有时会导致中耳粘连和听力下降。
根据术中发现，我们选择了106例患有慢性中耳炎、中耳粘连且听小骨完整的患者。这些患者接受了单阶段鼓室成形术，术中有的插入了硅橡胶片，有的未插入。术前以及术后1个月和12个月进行听力测定。
与未插入硅橡胶片的患者相比，插入硅橡胶片的患者在术后1年时气导、骨导及气骨导间距平均值明显更好。
