Abstract

The use of traditional electrocautery is prohibited in revision or replacement cochlear implant surgery because of the concern for end organ tissue damage. Additionally, electrical current spread to the malfunctioning device could interfere with an accurate cause-of-failure analysis. Clinical reports have confirmed the utility of the Shaw scalpel for dermatologic, ophthalmic, and head and neck surgery. The Shaw scalpel is a thermally activated cutting blade that provides a bloodless field through immediate capillary and small vessel hemostasis. Avoidance of wound and flap complications is of primary concern in cochlear implant surgery. The long-term wound healing compared favorably to that of other surgical cutting instruments in several experimental reports. We have routinely used the Shaw scalpel in revision cochlear implant surgery and in primary surgery whenever electrocautery was contraindicated. We have retrospectively evaluated 22 cases in which the Shaw scalpel was used for cochlear implant revision and primary surgery. The chart review included patient demographics, the indication for surgery, the contraindication for electrocautery, intraoperative surgical notes, the wound healing evaluation, the evaluation for alopecia, and postoperative speech understanding. No significant complications occurred intraoperatively, and the long-term wound healing results were no different from those obtained with conventional surgical techniques. The explanted devices were undamaged, and valuable diagnostic information could be obtained. All patients performed at or better than their preoperative levels on speech recognition testing. Our results indicate that the Shaw scalpel is a relatively safe, easy-to-use, and effective instrument.

肖氏手术刀在人工耳蜗翻修手术中的应用。
由于担心末端器官组织损伤,传统的电灼在人工耳蜗翻修或置换手术中被禁止使用。此外,电流扩散到故障设备可能会干扰对故障原因的准确分析。临床报告证实了邵氏手术刀在皮肤科、眼科和头颈部手术中的应用。Shaw手术刀是一种热激活的切割刀片,通过立即毛细血管和小血管止血提供一个无血的领域。避免伤口和皮瓣并发症是人工耳蜗手术的首要问题。在一些实验报告中,与其他手术切割工具相比,其长期伤口愈合良好。我们在人工耳蜗翻修手术和初级手术中常规使用邵氏手术刀。我们回顾性评估了22例使用Shaw手术刀进行人工耳蜗翻修和初级手术的病例。图表回顾包括患者人口统计、手术指征、电灼禁忌症、术中手术记录、伤口愈合评估、脱发评估和术后语言理解。术中无明显并发症发生,长期创面愈合效果与常规手术技术无明显差异。外植体无损伤,可获得有价值的诊断信息。所有患者在语音识别测试中的表现均达到或优于术前水平。我们的研究结果表明,Shaw手术刀是一种相对安全,易于使用和有效的工具。
