Therefore, our study aimed to develop a novel bilateral costal cartilage harvesting (BCCH) method to prevent and reduce thoracic deformities.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients with unilateral microtia who underwent either UCCH (<jats:italic>n<\/jats:italic>\u2009=\u200950) or BCCH (<jats:italic>n<\/jats:italic>\u2009=\u200946) were enrolled in this study. The grafts for the BCCH group were harvested from the 6th costal cartilage of the ipsilateral hemithorax and the 7th and 8th cartilage from the other hemithorax. Computed tomography and physical examination were performed to identify any physical deformities in the chest contours post\u2010surgery. The cosmetic appearance of the thoracic scars post\u2010surgery was evaluated using the Scar Cosmesis Assessment and Rating Scale (SCAR) and Visual Analogue Scales (VAS cosmetic). The numerical rating scale (NRS) was used to quantify the pain in donor sites. The reconstructed ears were assessed during the follow\u2010up period.<\/jats:p><\/jats:sec><jats:sec><jats:title>Result<\/jats:title><jats:p>None of the patients in the BCCH group developed thoracic deformities, while 16 patients within the UCCH group developed mild (<jats:italic>n<\/jats:italic>\u2009=\u200912) or severe (<jats:italic>n<\/jats:italic>\u2009=\u20094) thoracic deformities (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). The SCAR (3.09 vs. 2.92, <jats:italic>p<\/jats:italic>\u2009=\u20090.580) and VAS scores (0.96 vs. 0.90, <jats:italic>p<\/jats:italic>\u2009=\u20090.813) did not differ significantly between the two groups. For both treatment arms, the NRS scores were highest on the first\u2010day post\u2010surgery and gradually dropped over the 10\u2009days. No significant differences were found in the NRS scores and the aesthetic outcomes of the reconstructed ears between the two groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The BCCH method effectively reduced the incidence of thoracic deformity at the donor site without increasing postoperative pain and cosmetic concerns for patients.
