This study investigates the relationship between glottal gap and vocal function in patients with glottic incompetence dysphonia. Twenty patients with vocal fold paralysis (VFP), 17 patients with vocal fold atrophy (VFA), and five patients with sulcus vocalis (SV) were examined. Glottal gap area at the most closed point of vibration was measured using digitized videostroboscopic images. Glottal gap area was correlated with acoustic and aerodynamic measures of vocal function. Patients with VFP had the largest glottal gaps and had significantly worse vocal function than did the patients with VFA or SV. Regardless of groups, however, where glottal gap size was similar, there was no difference in vocal function. Therefore vocal function was mainly influenced by glottal gap size, not by whether glottic incompetence was the result of VFP, VFA, or SV.
本研究调查声门关闭不全性发音障碍患者的声门间隙与发声功能之间的关系。对20例声带麻痹（VFP）患者、17例声带萎缩（VFA）患者和5例声带沟（SV）患者进行了检查。使用数字化频闪视频图像测量振动最闭合点处的声门间隙面积。声门间隙面积与发声功能的声学和空气动力学指标相关。VFP患者的声门间隙最大，其发声功能明显比VFA或SV患者差。然而，无论在哪一组中，只要声门间隙大小相似，发声功能就没有差异。因此，发声功能主要受声门间隙大小的影响，而不是受声门关闭不全是由VFP、VFA还是SV所致的影响。
