For patients with concha-type microtia, surgical intervention and the degree of deformity may affect the growth rate of the auricular cartilage, which is different at different ages. This study aimed to explore the auricular growth potential of patients with concha-type microtia at different ages after auricular cartilage stretching surgery.
A total of 66 patients with unilateral grade II and III concha-type microtia were involved in this prospective cohort study. All patients underwent auricular cartilage stretching surgery. Relevant data were collected before surgery, immediately after surgery, and at the last follow-up.
The perimeter, width, and length of auricle, between each follow-up, was statistically significant, which supported the effect of surgery and auricular development. For patients in the grade II group, no statistical significance was found in the difference in the perimeter, width, and length between the affected and normal auricle. For the patients in the grade III group, the difference in the relevant indexes of the affected auricle was significantly different from those of the normal auricle. Between subgroups divided according to their age, the growth potential of affected auricle with the same degree of deformity was statistically significant.
Growth potential of the affected auricle of the grade II group was consistent with that of the normal auricle, which was significantly higher than that of the grade III group. For patients at different ages, auricles grew faster before 3 years of age. Surgical intervention improved the auricular aesthetics and released the auricular growth potential. Thus, surgical intervention should be recommend as early as possible.
对于贝壳型小耳畸形患者，手术干预和畸形程度可能会影响耳软骨的生长速度，不同年龄的生长速度不同。本研究旨在探讨不同年龄贝壳型小耳畸形患者耳软骨伸展术后的耳廓生长潜力。
本前瞻性队列研究共纳入 66 例单侧 II 度和 III 度贝壳型小耳畸形患者。所有患者均行耳软骨伸展术。在术前、术后即刻和末次随访时收集相关数据。
耳廓的周长、宽度和长度在每次随访之间均有统计学意义，这支持了手术和耳廓发育的效果。对于 II 度组患者，患侧和健侧耳廓的周长、宽度和长度差异无统计学意义。对于 III 度组患者，患侧耳廓的相关指标差异有统计学意义。根据年龄分组的亚组之间，相同畸形程度的患侧耳廓的生长潜力有统计学意义。
II 度组患侧耳廓的生长潜力与健侧耳廓一致，明显高于 III 度组。对于不同年龄的患者，3 岁以前耳廓生长较快。手术干预改善了耳廓美观，释放了耳廓生长潜力。因此，建议尽早进行手术干预。
