  Ultrasonography (USG) has been proven to be a fast, easily available, and cost-effective diagnostic tool in evaluating various organs of the body, however, its use in the evaluation of the larynx has not been popular. In this cross-sectional quantitative study 71 healthy volunteer, 20 - 40 years of age got ultrasound with linear transducer (7 - 13 MHz) in B-mode. Obtained data were analyzed using SPSS ver.20 software and shown in frequency, percentages and bar diagram. The mean length of Laryngeal Inlet, Glottis and Tracheal Air Column is 1.049, 0.630, and 1.131 respectively in female. In male the mean length of Laryngeal Inlet, Glottis and Tracheal Air Column is 1.22, 0.70 and 1.34 cm respectively. High frequency linear transducer has proven to be most appropriate in evaluating the larynx. This study has revealed the potential utility of ultrasound to assess the structural anatomy of larynx specially focusing at the hyoid bone level, thyroid cartilage level and cricoids cartilage level and creating normal values of laryngeal inlet, glottis opening and tracheal air column through sonography which can be used in various clinical applications. The measurement gained during this study was proven to be easily reproducible.
