Rigid endoscopes can improve visualization of the tympanic space compared to traditional microscopic techniques. This study investigates whether use of transcanal endoscopic ossiculoplasty influences audiologic outcomes compared to microscopic ossiculoplasty following chronic ear surgery in children.
Comparative cohort study at two tertiary care centers.
Retrospective review of pediatric chronic ear cases where ossiculoplasty was performed from February 2009 to March 2018.
We identified 100 ears that underwent endoscopic ossiculoplasty and 100 ears that underwent microscopic ossiculoplasty. The mean age was 11 years (range, 4-18 years) with 63% males. There were no significant differences in these parameters between the two groups. Subjects underwent either primary ossiculoplasty or ossiculoplasty during second-look procedures. There was no significant difference in air conduction pure tone average (PTA) after microscopic cases compared to endoscopic cases (-12.5 dB vs. -10.5 dB, P = .40). These results were independent of prosthesis type. Microscopic ossiculoplasty was significantly more likely to use a post-auricular approach (P = .0001). There was no difference in complication rate between the two groups. The malleus was more likely to be absent or removed prior to endoscopic ossiculoplasty (P = .0004) with no significant difference in the change in PTA between groups.
Transcanal endoscopic ossiculoplasty was found to have equivalent audiometric outcomes with significantly fewer post-auricular approaches and no increase in complications compared to microscopic ossiculoplasty. While the malleus was more likely to be absent in endoscopic cases, this did not appear to influence the change in PTA.

与传统显微镜技术相比，硬性内镜可改善鼓室空间的可视化。本研究调查了在儿童慢性耳科手术后，经耳道内镜听骨链成形术与显微镜下听骨链成形术相比，是否会影响听力结果。
在两个三级医疗中心进行的比较队列研究。
回顾性分析2009年2月至2018年3月期间行听骨链成形术的小儿慢性耳科病例。
我们确定了100例行内镜听骨链成形术的耳和100例行显微镜下听骨链成形术的耳。平均年龄为11岁（范围4 - 18岁），男性占63%。两组在这些参数上无显著差异。受试者接受初次听骨链成形术或在二次探查手术中进行听骨链成形术。显微镜下手术病例与内镜手术病例相比，气导纯音平均听阈（PTA）无显著差异（-12.5dB对-10.5dB，P = 0.40）。这些结果与假体类型无关。显微镜下听骨链成形术更有可能采用耳后入路（P = 0.0001）。两组并发症发生率无差异。在内镜听骨链成形术前，锤骨更有可能缺失或被切除（P = 0.0004），两组间PTA的变化无显著差异。
发现经耳道内镜听骨链成形术与显微镜下听骨链成形术相比，听力测量结果相当，耳后入路显著减少，且并发症无增加。虽然内镜手术病例中锤骨更有可能缺失，但这似乎并未影响PTA的变化。
