An ultrasound photo assessing vocal cord mobility in a patient with VC paralysis (abducted type) by drawing imaginary perpendicular line from the junction between both thyroid cartilage anteriorly where distance 3 (0.14 mm) and 4 (0.38) represent contribution of the right VC in respiratory chink in both respiration and phonation. Where distance 5 (0.33 mm) and 6 (0.38 mm) represent contribution of the right VC in respiratory chink in both respiration and phonation
