Objectives：It is important to observe vocal fold vibration in detail for phonatory research. Ex-vivo larynx is a representative universally used material for phonatory research. We developed a new ex-vivo larynx holder device to fix the larynx more easily and to provide vocal fold adduction effectively for ex-vivo larynx experiments. To evaluate the utility of this laryngeal holder device, we performed two-dimensional videokymography (2D VKG) Methods：We developed the new ex-vivo laryngeal holder device for mounting ex-vivo larynx. The 2D VKG was used to assess the vocal fold vibration of ex-vivo canine larynx fixed with our ex-vivo larynx holder device. Results：Our ex-vivo larynx holder device provided fixing the ex-vivo larynx more easily and fast without additional arytenoid approximation. With this ex-vivo laryngeal holder device, we could evaluate ex-vivo canine vocal fold vibration successfully using 2D VKG without additional arytenoid approximation and mucosal dehydration. Conclusions：This newly developed ex-vivo laryngeal holder device is expected to help the phonatory researchers to study vocal cord movement more easily.
