The primary objective of this study was to compare the utility of high-speed video (HSV) to videostroboscopy (VS) in the assessment of adolescents with normal and abnormal larynges. A secondary objective was to evaluate the ease of assessment of adolescents with HSV.
Case series with chart review.
Tertiary academic health care center.
This study involved a retrospective review of recordings of 7 adolescents assessed with both HSV and VS. The 14 recordings were randomized and presented to 4 groups of blinded evaluators: 2 fellowship-trained laryngologists, 2 speech language pathologists (SLP) with multiyear experience working in a voice clinic, 2 pediatric otolaryngologists, and 2 otolaryngology residents. Raters were asked to evaluate the videos using a standardized scoring tool. Raters also completed a questionnaire assessing their opinion of the HSV and VS recordings.
Evaluators required more time to complete their assessment of VS recordings (2.95 min ± 2.41 min) than HSV recordings (2.31 min ± 1.92 min) (P = .004). There was no difference in ease of evaluation (P = .878) or diagnostic accuracy within evaluator groups by recording modality (P = .5). The overall agreement between VS and HSV was moderate (kappa [SE] = 0.446 [0.029]). The debrief questionnaire revealed that 5 of 8 (62.5%) preferred VS to HSV.
This is the first comparative study between HSV and VS in patients under 18 years of age. HSV permitted faster evaluation than VS, but there was no difference in diagnostic accuracy between the 2 modalities. The evaluators preferred VS to HSV.
本研究的主要目的是比较高速视频（HSV）与频闪喉镜检查（VS）在评估喉部正常和异常青少年中的效用。次要目的是评估使用HSV对青少年进行评估的难易程度。

本研究对7名接受HSV和VS评估的青少年的记录进行了回顾性分析。14份记录被随机分组并呈现给4组不知情的评估人员：2名接受过专科培训的喉科医生、2名在嗓音诊所工作多年的言语语言病理学家（SLP）、2名儿科耳鼻喉科医生和2名耳鼻喉科住院医师。要求评估人员使用标准化评分工具对视频进行评估。评估人员还完成了一份问卷，以评估他们对HSV和VS记录的看法。
与HSV记录（2.31分钟±1.92分钟）相比，评估人员完成VS记录评估所需的时间更长（2.95分钟±2.41分钟）（P = 0.004）。评估的难易程度（P = 0.878）或评估组内不同记录方式的诊断准确性（P = 0.5）没有差异。VS和HSV之间的总体一致性为中等（kappa[SE]=0.446[0.029]）。总结问卷显示，8名中有5名（62.5%）更喜欢VS而不是HSV。
这是第一项针对18岁以下患者比较HSV和VS的研究。HSV比VS评估速度更快，但两种方式的诊断准确性没有差异。评估人员更喜欢VS而不是HSV。
