　OKUYA reports two cases of cleft palate successfully treated by use of prosthesis. In both cases the attempts at surgical correction in early years of patients life had failed. The first case, a man aged 21, by use of prosthesis and speech training thereafter showed marked improvement that he was able to convey an intelligible telephone conversation. The second case, a man aged 19, likewise made a marked improvement of his speech.
