3年以上聴力経過を観察しえた前庭水管拡大に伴う難聴14例28耳 (男性7例, 女性7例) における長期的な聴力域値の変化と, 難聴の急性増悪のエピソードについて検討した。聴力域値が3分法平均聴力で10dB以上悪化した進行耳を6耳 (21%), 難聴の急性増悪を4回以上反復した増悪反復耳を11耳 (39%) に認めた。 これら臨床的に経過不良の症例では, 誘因なく難聴の急性増悪を生じ, しばしばめまいを伴った。前庭水管拡大症例が誘因なくめまいを伴って難聴の急性増悪をきたしたときは, 治療や経過観察をより注意深く行う必要があると思われた。 前庭水管拡大には, 容易に内耳障害を生じる経過不良な群と, 経過が比較的安定した群が存在する可能性が示唆された。

Two cases of psychogenic hearing loss combined with psychogenic aphonia are reported.Case one was a 15-year-old female with psychogenic hearing loss that appeared just before taking a high school entrance examination. After she passed the examination, the complaint of hearing loss was reduced. Three years later she suddenly suffered from psychogenic aphonia prior to taking a college entrance examination. The aphonia also diminished after she passed the examination. Both the hearing loss and aphonia were attributed to the stress caused by the entrance examinations.Case two was a 26-year-old female who suddenly suffered from profound hearing loss and aphonia simultaneously. The conditions were brought on apparently by a psychogenic reaction to a stressful relationship with her mother-in-law.In both cases, the threshold of auditory brain stem evoked response was normal while the threshold of pure tone audiogram indicated profound sensorineural hearing loss. The phonolaryngogram was useful for diagnosis and evaluation of voice disturbance.
