Hemihypertrophy (HH) is a rare congenital malformation usually recognized at birth. It is often diagnosed due to impaired aesthetics and mobility caused by asymmetry of the face, body, or limbs. Some patients are diagnosed due to the presence of tumors and mental abnormalities.
A 14-year-old boy with hoarseness since infancy and progressively increasing with age. Laryngoscopy and CT of the larynx suggested bilateral asymmetry of the laryngeal structures, and voice analysis suggested severe voice disorders. The boy had no history of trauma or other medical conditions, but had physical asymmetry since birth, which coincided with the laryngeal asymmetry. After a detailed examination and evaluation, we considered that his voice disorders were unexpectedly caused by crossed idiopathic HH. Since the boy in his growth spurts is not a candidate for surgery, we implemented individualized voice correction therapy. After practicing, the boy's voice disorders were significantly relieved.
Congenital HH can cause asymmetrical development of the larynx, which leads to voice disorders. Voice correction therapy is an effective treatment for patients unsuitable for surgery.
半侧肥大（HH）是一种罕见的先天性畸形，通常在出生时即可识别。它常因面部、身体或四肢不对称导致美观受损和活动受限而被诊断出来。一些患者是由于存在肿瘤和精神异常而被诊断。
一名14岁男孩自婴儿期起就声音嘶哑，且随年龄增长逐渐加重。喉镜检查和喉部CT显示喉部结构双侧不对称，语音分析提示严重的语音障碍。该男孩无外伤史或其他疾病史，但自出生以来身体就不对称，这与喉部不对称情况相符。经过详细检查和评估，我们认为他的语音障碍意外地是由交叉性特发性HH引起的。由于处于生长发育期的该男孩不适合手术，我们实施了个性化的语音矫正治疗。经过练习，男孩的语音障碍得到了明显缓解。
先天性HH可导致喉部不对称发育，进而引起语音障碍。语音矫正治疗是不适宜手术患者的有效治疗方法。
