    Abstract:
    BACKGROUND: The approach to constructing the cartilage framework for ear reconstruction is sufficiently established. However, there is still no consensus about the age of initiation of surgical treatment. This study aims to assess the development and growth of the costal cartilage to determine the best age to perform ear reconstruction surgery. METHODS: Out of 107 patients, we used presurgical treatment data for 40 patients and medical records for 67 patients aged 5-40. Computed tomography (CT) scans were performed, and average parameters were calculated (length, width, thickness, cartilage density, and standard deviation in Hounsfield units) of the cartilaginous part of the 6th, 7th, 8th, and 9th ribs. RESULTS: The required values were reached at 9-10 years old. CONCLUSION: The criteria for starting surgical treatment in the Russian population was determined by the width of the 6th-7th ribs synchondrosis, which must be equal to the width of a healthy auricle, and the length of the 8th rib should be longer than 9 cm. Therefore, the optimal age for ear reconstruction with autologous costal cartilage is 10 years and older. However, reconstruction can be made earlier in specific cases, according to height and weight and the preoperative CT scan.
