Functional voice disorders. A review of 109 patients.

The records of 109 patients, presenting with functional voice disorder during the years 1977-1981, have been reviewed. The mean age was 45 years and the F : M ratio is 2 : 1. Excess voice use was not obviously an aetiological factor. Sixty-one of the 109 patients (56 per cent) were cured by speech therapy, in that their voices returned to their pre-morbid state, and a further 28 (26 per cent) were improved by therapy; seven patients (6 per cent) did not improve and 13 (12 per cent) were lost to follow-up. Of the patients that were 'cured', 54 per cent were discharged after three months' treatment and 72 per cent after six months' treatment. Eight per cent required treatment for more than a year.
