All patients had a plain low-dose multislice CT chest. The length of costal cartilages of sixth to ninth ribs bilaterally and width and height of sixth and seventh rib costal cartilage synchondrosis were measured in 3D reconstructed true size coronal images with best possible length displayed. All patients had high-resolution computed tomography (HRCT) temporal studies done to evaluate for associated anomalies in external canal, middle ear cavities, and inner ear structures. Eleven patients had simultaneous HRCT temporal bone done after plain CT chest and rest who had done recent prior study were reviewed without repetition of study.<\/jats:p><jats:p>\n          Results\u2003There were 19 males and 16 females for 3D CT rib study. Average age of the participants was 16.5 years. The average width of synchondrosis of sixth and seventh rib was 15.4\u2009mm on right side and 14.7\u2009mm on left side, average height of synchondrosis was 28.5\u2009mm on right side and 30.7\u2009mm on left side. Average length of the eighth rib costal cartilage was 88.6\u2009mm on the right side and 90.5\u2009mm on the left side. Average length of the ninth rib was 63.2\u2009mm on the right side and 58.2\u2009mm on the left side.
