Abstract
We experienced a case of 16-year-old girl "A" with psychogenic deafness caused by a family conflict. "A" had seen the father's domestic violence against the mother with alcoholic inebriation almost daily, and it made tense in her daily life. At her early school age, difficulty of hearing appeared, and got no medical diagnosis which can satisfy the severe unpleasant symptom. On the parents had been divorcing when she was 10 years old and also after divorce, she was forced to play a role of coordinator between the parents, which made her daily life tense more. Therefore, hearing loss appearing in her early school age had been prolonged until her being 16 years old, and the symptom was eventually diagnosed with psychogenic deafness. She had to play a role of domestic coordinator, so that her "not hearing" was thought to work as defense for not manifesting what she truly hoped in front of her parents. In the near future with increase of divorce and other complex family issues, it is thought that more cases with domestic problem may be exhibited as somatization by women and/or children.
