To establish an ideal animal model for studying subglottic stenosis, we assessed the size and morphology of the normal rabbit\u2019s laryngotracheal airway by helical CT. We measured luminal dimensions at the levels of the arytenoid and cricoid cartilages and the first, third, and eighth tracheal rings. At all levels, the axial slices were used to calculate the maximum anteroposterior (AP) dimension, transverse dimension, and cross-sectional areas. We measured the tracheal length from the cricoid to the third and eighth tracheal rings on sagittal reformation. We assessed the hyoid, thyroid, cricoid, arytenoid, and tracheal rings for the presence of calcific or soft tissue densities. We also addressed the presence or absence of pre-epiglottic and paraglottic fat.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The mean AP tracheal dimension\u00a0\u00b1\u00a0standard deviation (SD) was 8.6\u00a0\u00b1\u00a00.5\u00a0mm at the arytenoid level, 8.2\u00a0\u00b1\u00a00.7\u00a0mm at the cricoid level, and 7.7\u00a0\u00b1\u00a00.2\u00a0mm at the first tracheal ring level. The transverse tracheal dimension\u00a0\u00b1SD was 5.3\u00a0\u00b1\u00a00.1\u00a0mm at the arytenoid level, 5.5\u00a0\u00b1\u00a00.5\u00a0mm at the cricoid level, and 6.1\u00a0\u00b1\u00a00.6\u00a0mm at the first tracheal ring level.

There was complete calcification of the hyoid in all rabbits. Only two rabbits showed complete thyroid, arytenoid, or tracheal ring calcification. The remaining airway components were otherwise either uncalcified or partially calcified. The uvula, epiglottis, aryepiglottic fold, vallecula, piriform sinus, true\/false vocal cords, and pre-epiglottic\/paraglottic fat were not seen in any rabbit.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Helical CT investigation provides good, highly definitive anatomic details of the larynx and trachea in rabbits.
