To summarise published research investigating maximal temperatures associated with endoscopes used in otology. Possible thermal issues surrounding the use of endoscopes in middle-ear surgery are discussed, and recommendations regarding the safest ways to use endoscopes in endoscopic ear surgery are made.
A non-systematic review of the relevant literature was conducted, with descriptive analysis and presentation of the results.
There are currently no reports of any temperature-related deleterious effects in patients having undergone endoscopic ear surgery. There is debate regarding heat issues in endoscopic ear surgery, with a limited body of work documenting potential negative impacts of middle-ear heat exposure from endoscopes. The diameter of endoscope, type of light source used, distance from endoscope tip and duration of exposure are highlighted potential factors for high temperatures in endoscopic ear surgery.
There is a trend towards endoscopes being used routinely in ear surgery. Simple practice points are recommended to minimise potential thermal risks.
总结已发表的关于耳科所用内镜相关最高温度的研究。讨论了中耳手术中使用内镜可能存在的热问题，并就内镜耳科手术中使用内镜的最安全方法提出建议。
对相关文献进行非系统综述，并对结果进行描述性分析和呈现。
目前尚无关于接受内镜耳科手术患者出现任何与温度相关有害影响的报道。内镜耳科手术中的热问题存在争议，记录内镜中耳热暴露潜在负面影响的研究较少。内镜直径、所用光源类型、距内镜尖端的距离和暴露持续时间是内镜耳科手术中高温的潜在影响因素。
内镜在耳科手术中的常规使用呈上升趋势。建议采取简单的操作要点以尽量降低潜在的热风险。
