The purpose of this study was to compare the hearing outcomes after surgery with reconstruction of the external auditory canal in combination with tympanoplasty, radiotherapy (RT) alone, and surgery followed by postoperative RT for T1 to 2N0M0 external auditory canal cancer.
We performed a retrospective, single-institution review of consecutive patients with early-stage external auditory canal cancer treated with surgery and/or RT between April 1997 and August 2013. Audiological data included the pretreatment hearing thresholds and those obtained at 12 months after the completion of therapy.
When we compared the functional gains for air-conduction pure-tone average thresholds and mean air-bone gaps, those in the surgery group (n = 10) were significantly higher than those in the RT (n = 13) and surgery + RT (n = 5) groups.
Adequate techniques for reconstruction of the external auditory canal in combination with tympanoplasty after complete surgical resection is useful for hearing preservation in addition to good survival outcomes. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1110-E1116, 2016.
本研究旨在比较外耳道重建联合鼓室成形术、单纯放疗（RT）以及手术联合术后放疗治疗T1至2N0M0期外耳道癌后的听力结果。
我们对1997年4月至2013年8月间在单一机构接受手术和/或放疗的连续性早期外耳道癌患者进行了回顾性研究。听力学数据包括治疗前听力阈值以及治疗结束后12个月时获得的听力阈值。
当我们比较气导纯音平均阈值和平均气骨导间距的功能改善情况时，手术组（n = 10）的改善程度显著高于放疗组（n = 13）和手术 + 放疗组（n = 5）。
在完整手术切除后，采用适当的外耳道重建联合鼓室成形术技术除了能带来良好的生存结果外，对听力保存也很有用。© 2015威利期刊公司。头颈外科38: E1110 - E1116, 2016。
