The diagnostic procedure of phonation is dominated by subjective assessment tools. It seems reasonable to seek methods of quantitative glottal cycle assessment.
The aim of our study was the analysis of open quotients (OQ) of the glottis.
One hundred and twenty-four people were included in the study. Methodology was based on tools available in everyday phoniatrics practice - laryngovideostroboscopy (LVS) and electroglottography (EGG). There were statistically significant differences between control and studied group. Vocal fold polyps, nodules and edema influence glottal function in a different manner, what can be illustrated by objective glottal function parameters. Establishing Videostroboscopic Open Quotient values from three parts of glottis and Electroglottographic Quasi Open Quotient (QOQ) value, can help in dividing patients with benign lesions of vocal folds according to the type of disease.
Measurement of the open quotient from three parts of the glottis helps to differentially diagnose and localize glottal vocal fold lesions. Videostroboscopic Open Quotient and Electroglottographic QOQ values can be used to quantify the glottal cycle. Videostroboscopic Open Quotient, Electroglottographic QOQ and their ratio varies depending on the type of organic dysphonia.
发声的诊断程序主要依赖主观评估工具。寻求定量声门周期评估方法似乎是合理的。
我们研究的目的是分析声门的开放商数（OQ）。
124人纳入本研究。方法基于日常嗓音医学实践中可用的工具——喉动态镜检查（LVS）和电声门图（EGG）。对照组和研究组之间存在统计学显著差异。声带息肉、小结和水肿以不同方式影响声门功能，客观的声门功能参数可以说明这一点。从声门的三个部分建立动态镜开放商数值和电声门图准开放商数（QOQ）值，有助于根据疾病类型对声带良性病变患者进行分类。
测量声门三个部分的开放商数有助于鉴别诊断和声门声带病变的定位。动态镜开放商数和电声门图QOQ值可用于量化声门周期。动态镜开放商数、电声门图QOQ及其比值因器质性发声障碍的类型而异。
