Free costochondral grafts have been used to construct the absent ascending ramus and condylar head of 22 children with hemifacial microsomia (HFM) who were less than 14 years of age. Evidence of continued growth was demonstrated in all patients. Growth was determined by measurement of cephalograms or by inference; if the patient grew extensively in height but his/her face remained symmetric, the graft was inferred to have grown. In two patients, considerable overgrowth occurred, displacing the chin to the opposite side and causing a class III malocclusion. Variations in age or type of adjunctive operations did not affect growth. There appears to be no single explanation for all findings. Because all of the grafts grew, early joint construction and correction of hemifacial microsomia are advocated.
游离肋软骨移植已被用于为22例年龄小于14岁的半侧颜面短小畸形（HFM）儿童构建缺失的升支和髁突头部。所有患者均显示有持续生长的证据。通过测量头影测量片或推断来确定生长情况；如果患者身高显著增长但其面部仍保持对称，则推断移植组织已生长。在两名患者中，出现了明显的过度生长，将下巴推向对侧并导致III类错牙合。辅助手术的年龄或类型差异并不影响生长。对于所有这些发现，似乎没有单一的解释。由于所有移植组织都生长了，因此提倡早期进行关节构建和矫正半侧颜面短小畸形。
