Abstract:
Objective:To investigate the effect of titanium wire-absorbable suture dual line combined firm stitching technique in costal cartilage framework shaping for auricular reconstruction in congenital microtia patients.Methods:A retrospective study was conducted on 120 patients with congenital microtia who underwent auricular reconstruction surgery at the Plastic Surgery Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College from January 2020 to December 2021. Among these, 86 were male and 34 were female, with an age range of 6-15 (8.5±2.1) years. All patients underwent auricular reconstruction using the expanded skin flap method, and the titanium wire-absorbable suture dual line combined firm stitching technique was used to construct a multi-layer three-dimensional autologous costal cartilage framework. Postoperative follow-up was conducted for 1 to 3 years to evaluate the morphology, stability, patient satisfaction, and occurrence of adverse reactions.Results:Of the 120 patients, 119 (99.2%) achieved primary healing. The reconstructed auricles were lifelike with clear substructures, and the long-term shape of the auricles remained stable without significant deformation. One patient developed a local skin infection and ulceration, leading to exposure of the cartilage framework, which was successfully repaired using a temporal fascia flap and free skin graft. A total of 85.8% (103/120) of the patients were satisfied with the postoperative results, 13.3% (16/120) rated the outcome as average, and 0.8% (1/120) were dissatisfied. No cases of hematoma or flap necrosis were observed in any of the patients.Conclusion:The costal cartilage framework, constructed using the titanium wire-absorbable suture dual line combined firm stitching technique, demonstrates good clinical effects for auricular reconstruction with no severe adverse reactions.
