Homma says in cases of defective speech caused by tonguetie speech corrective exercise alone is inadequate for relief of this condition but, when those corrective exercises are ateceded by frenotomy, the patients should, be completely cured. An adult male, 22 years of age, complaining of speech defect was diagnosed as the condition being due to tonguetie. Frenotomy is performed and corrective exercises in speech are later instituted. The patient makes a complete recovery of his normal speech as is shown by records of his palatographs in comparison to those of normal persons.
