Thanks to videostrobokymography the vocal fold vibration from particular area of glottal chink, can be assessed in an objective way.
Evaluation of objective parameters of vocal fold vibration with the usage of videostrobokymography in patients with different voice disorders.
Material of the study included patients treated in the Institute of Physiology and Pathology of Hearing, Audiology and Phoniatrics Clinic. 82 patients with normal voices, vocal fold nodules, polyps, Reinke edema, vocal cord paralysis and functional dysphonia were enrolled into the study. Open Quotient (OQ) from frontal, middle and dorsal third of vocal folds were measured. T-Student test was used for statistical analysis.
The study revealed differences of OQ in control group and patients with organic or functional dysphonia. Differences in parameters were calculated for each vocal fold region. The mean value of OQ in control group was 0.56 (frontal third), 0.55 (middle third), 0.597 (dorsal third). Statistical significant differences of OQ calculated from separate glottal chink areas, were observed in Reinke edema (from frontal and middle third) and vocal cord paralysis (from frontal third).
Videostrobokymography is an useful complement to classical stroboscopy. Objective parameters enables the objectification of vibratory activities. Videostrobokymography is helpful in differential diagnosis of voice disorders.
得益于频闪喉动态成像技术，声门裂隙特定区域的声带振动能够以客观的方式进行评估。
运用频闪喉动态成像技术评估不同嗓音障碍患者声带振动的客观参数。
研究材料包括在听力、听力学与语音病理学研究所门诊接受治疗的患者。82例嗓音正常、有声带小结、息肉、任克氏水肿、声带麻痹和功能性发声障碍的患者纳入研究。测量声带前、中、后三分之一处的开放商（OQ）。采用t检验进行统计分析。
研究揭示了对照组与器质性或功能性发声障碍患者在开放商方面的差异。计算了每个声带区域参数的差异。对照组开放商的平均值分别为：前部三分之一处0.56，中部三分之一处0.55，后部三分之一处0.597。在任克氏水肿（前部和中部三分之一处）和声带麻痹（前部三分之一处）患者中，观察到从不同声门裂隙区域计算出的开放商存在统计学显著差异。
频闪喉动态成像技术是传统频闪喉镜检查的有益补充。客观参数能够使振动活动客观化。频闪喉动态成像技术有助于嗓音障碍的鉴别诊断。
