Clinical effect evaluation and complication analysis of different auricle reconstruction of congenital microtia

This study compared the clinical efficacy and complications of autogenous rib cartilage stent and Medpor stent auricle reconstruction in patients with congenital microtia. A total of 300 patients with congenital microtia were selected as the research objects. 150 patients in the auricle reconstruction group with autologous rib cartilage stent and 150 patients in the auricle reconstruction group with Medpor stent were selected. Postoperative follow-up was conducted to observe whether the shape, color, size, and position of the reconstructed auricle were good, and to compare whether the cranial auricle Angle was consistent with the healthy lateral auricle, so as to judge whether the reconstructed auricle was successful. The incidence of postoperative complications, such as infection and stent exposure was recorded. The postoperative satisfaction and quality of life scores were compared between the two groups. Two operation methods of the auricle reconstruction effect showed no obvious difference (P>0.05), but the incidence of auricle reconstruction scaffold exposing Medpor stenting was significantly higher than those of autologous rib cartilage auricle reconstruction. The satisfaction and quality of life scores of patients in the autologous rib cartilage group were significantly higher than those in the Medpor stent group (P<0.05). Although there was no significant difference between auricle reconstruction with autologous rib cartilage scaffold and Medpor stent implantation in the improvement rate of microtia, there were fewer complications after autologous rib cartilage stent implantation, but higher patient satisfaction and quality of life.
