気道狭窄をきたした乳児頸部腫瘤の2症例

Air-way Obstruction in Two Infants with Mass in the Neck

　I．緒言

　乳児にみられる頸部腫瘤についてはわれわれ耳鼻科医もしばしば遭遇する疾患の1つであり，これまでにも多くの報告があり，その種類については多種多様である。しかしながら，その発生部位，進展部位によつては気道圧迫により，喘鳴，呼吸困難をきたすことは周知のごとくである。したがってまず気道確保ということが重要となり，その後早急に適切な処置が必要となる。また小児という特殊性に加えて，腫瘤の浸潤部位によっては治療が非常に困難な場合もあり，その対策には苦労するところである。今回筆者らは診断を異にし，気道狭窄をきたした乳児頸部腫瘤2例を経験したので報告する。

　Case 1 A 3-month-old boy presented with stridor and dyspnea, had a large retropharyngeal abscess along the sternocleid muscle extending down to the supraclavicular fossa. It was considered that acute inflammation due to the abscess was suppressed by a long-term, insufficient, treatment with antibiotics which were given when the patient had cold-like symptoms, and the air-way became obstructive by the massive abscess.

　Case 2 A 6-month-old girl was admitted to the hospital because of a mass in the neck and stridor. The mass was extirpated under general anesthesia, and a diagnosis of cystic hygroma was made by histological examination. It was considered that the content of a mass was changed to sanguinous by repeated punctures, and the volume of the mass increased so as to cause stridor and dyspnea as the result of air-way compression.
