For the evaluation of voice disorders, direct observation of vocal cord vibration is important. Among the various methods, laryngeal videostroboscopy (LVS) is widely used, but it was not a true image because it collects images from different cycles. In contrast, high-speed videoendoscopy and videokymography have much higher frame rates and can assess functional and mobility disorders. ⋯ Our system can provide images of various modalities simultaneously in real time and analyze morphological and functional vibratory patterns. It can be possible to provide a greater level of information for the diagnosis and treatment of vibratory disorders.

Case Reports
Three Simultaneous Cases of Spontaneous Pneumomediastinum With Epidural Pneumatosis During Vocal Training.
The aim of this study was to describe a case series of three simultaneous cases of spontaneous pneumomediastinum (SPM) with epidural pneumatosis during vocal training. ⋯ We report three simultaneous cases of SPM and epidural pneumatosis due to demanding vocal training. Further research on this subject is desired to identify risk factors.

We tested whether speaking voices of unfamiliar people could be matched to their singing voices, and, if so, whether the content of the utterances would influence this matching performance. Our hypothesis was that enough acoustic features would remain the same between speaking and singing voices such that their identification as belonging to the same or different individuals would be possible even upon a single hearing. We also hypothesized that the contents of the utterances would influence this identification process such that voices uttering words would be easier to match than those uttering vowels. ⋯ We can identify speaking and singing voices as the same or different even on just a single hearing. However, content interacts with mode such that words benefit matching of speaking voices but not of singing voices. Results are discussed within an attentional framework.

The study aims to (1) identify the botulinum toxin (BTX) dosing trend in a cohort of patients who received at least 20 injections for the treatment of adductor spasmodic dysphonia (ADSD), (2) describe two distinct BTX dosing trends in treating ADSD (a "classic" dosing trend that initially decreases before stabilizing, and a "fluctuating" dosing trend), and (3) determine if patients with the "classic" dosing trend differed in age or in dosing intervals from those with the "fluctuating" dosing trend. ⋯ The average BTX dose of patients with ADSD who receive long-term injections significantly decreases during the initial 10-15 injections before stabilizing. Patients who exhibit the "fluctuating" dosing pattern have a significantly shorter interval between injections than those with the "classic" dosing pattern.

Voice disorders that affect the quality of voice also result in varying degrees of psychological and social problems. The research question here is whether the correlations between Voice Handicap Index (VHI)-30 scores and objective acoustic measures differ in patients with different types of voice disorders. ⋯ Findings suggest that although the VHI-30 and the acoustic measurements of voice provide independent information, they are associated to some extent.
