For the evaluation of vocal cord vibration, laryngeal videostroboscopy is commonly used and laryngeal high-speed videoendoscopy has been seldom used, but these modalities may be hard to evaluate subtle change of vibratory pattern. In this situation, kymogram using video kymography and line scanning digital kymography seems to be more accurate. Two-dimensional scanning digital kymography can analyze the entire vocal cord. If both line scanning and two-dimensional scanning digital kymography are used simultaneously, subtle vibratory changes of the vocal cords can be effectively identified. 27-year-old male had taken a blunt trauma to the left lateral neck on May 5, 2010. Left arytenoid showed swelling with submucosal hemorrhage and decreased mobility of the left vocal cord was noted. On neck CT, fracture of the left arch of the cricoid cartilage was identified. After trauma, he frequently felt easy fatigability during phonation. He was referred to the senior author (WSG) on Dec. 28, 2016. He had diagnosed subtle atrophic changes anterior part of left vocal cord. Simultaneous multi-modal examinations using high-speed videoendoscopy, line scanning and two-dimensional scanning digital kymography may be useful to assess the subtle vibratory changes in the vocal folds.
