一過性鼻咽腔閉鎖機能不全を呈した小児2例の開鼻声と構音障害の経過 Unilateral Isolated Paralysis of the Soft Palate in Two Childhood Cases
一側の軟口蓋麻痺により一過性に鼻咽腔閉鎖機能不全を呈した7歳女児と6歳男児について開鼻声と構音障害の経過を報告した.2例とも開鼻声と鼻腔への飲み物の逆流が生じたが, 数週間でほぼ完治した.原因は6歳男児でウイルス感染が推察されたが, 他の1例については不明であった.2例とも鼻咽腔閉鎖機能は回復した.
Isolated asymmetrical palate palsy is a rare condition in childhood. We report on two cases. A 7-year-old girl exhibited nasal speech and nasal escape of fluids from the left nostril. The other case was a 6-year-old boy who also presented nasal speech and nasal escape of fluids from the left nostril. Typical features in both cases included sudden onset, hypernasality and nasal escape of fluids from one nostril. Near total recovery was achieved spontaneously within several weeks. The findings suggest the cause to be viral infection, but attempts at viral isolation were unsuccessful in one of the two cases. Symptoms improved within several weeks.
