Longitudinal Non-invasive Analysis of VOCAle Cord Function Based on Trans-laryngeal Ultrasound Acquisitions and Voice Recordings

The main objective of VOCALISE study is to propose a new approach allowing a better characterization of postoperative dysphonia. This involves associating with dynamic translaryngeal ultrasound optimized acquisitions of the vibration of each vocal fold in phonation simultaneously with voice recordings. A software program to analyze the displacement of arytenoids, markers of substitution of the vocal cords, will be developed to finely quantify the mobility of laryngeal structures, by combining classical methods of motion analysis and deep learning methods. This approach will be evaluated to follow speech therapy rehabilitation in patients with post-operative dysphonia following recurrent nerve injury.
