To summarize recent technological advancements and insight into the role of stroboscopy in laryngeal imaging.
Although stroboscopic technology has not undergone major technological improvements, recent clarifications have been made to the application of stroboscopic principles to video-based laryngeal imaging. Also recent advances in coupling stroboscopy with high-definition video cameras provide higher spatial resolution of vocal fold vibratory function during phonation. Studies indicate that the interrater reliability of visual stroboscopic assessment varies depending on the laryngeal feature being rated and that only a subset of features may be needed to be representative of an entire assessment. High-speed videoendoscopy (HSV) judgments have been shown to be more sensitive than stroboscopy for evaluating vocal fold phase asymmetry, pointing to the future potential of complementing stroboscopy with alternative imaging modalities in hybrid systems. Laryngeal videostroboscopy alone continues to play a central role in clinical voice assessment. Even though HSV may provide more detailed information about phonatory function, its eventual clinical adoption will depend on how remaining practical, technical, and methodological challenges will be met.
Laryngeal videostroboscopy continues to be the modality of choice for imaging vocal fold vibration, but technological advancements in HSV and associated research findings are driving increased interest in the clinical adoption of HSV to complement videostroboscopic assessment.
总结频闪喉镜在喉部成像中的最新技术进展及作用。
尽管频闪喉镜技术未经历重大技术改进，但近期对频闪喉镜原理在基于视频的喉部成像中的应用有了更清晰的认识。此外，将频闪喉镜与高清摄像机相结合的最新进展，在发声过程中提供了更高的声带振动功能空间分辨率。研究表明，视觉频闪喉镜评估的观察者间可靠性因所评估的喉部特征而异，且仅需部分特征即可代表整个评估。在评估声带相位不对称方面，高速视频内镜检查（HSV）的判断已被证明比频闪喉镜更敏感，这表明在混合系统中用替代成像方式补充频闪喉镜检查具有未来潜力。单独的喉部视频频闪喉镜检查在临床嗓音评估中仍发挥着核心作用。尽管HSV可能提供有关发声功能的更详细信息，但其最终在临床上的应用将取决于如何应对剩余的实际、技术和方法学挑战。
喉部视频频闪喉镜检查仍然是成像声带振动的首选方式，但HSV的技术进步及相关研究结果正推动人们对临床应用HSV以补充视频频闪喉镜评估的兴趣增加。
