An ultrasound photo assessing vocal cord mobility in a patient with VC paralysis (adducted type) by drawing imaginary perpendicular line from the junction between both thyroid cartilage anteriorly where distance 2 (0.43 mm) and 5 (0.29) represent contribution of the right VC in respiratory chink in both respiration and phonation. Where distance 3 (0.21 mm) and 6 (0.21 mm) represent contribution of the right VC in respiratory chink in both respiration and phonation
