Description

Mutational voice disorder is characterized by development in males aged 12 years, vocal cord congestion・edema as laryngeal findings and voice break as voice quality. We encountered a patient with findings that slightly differ from these characteristics (age, 15years old; laryngeal findings, glottic gap; voice quality, strong breathy hoarseness) and performed assessment·training. Close examinations such as inquiry confirmed that he developed this disorder manifested by falsetto-like phonation at the age of 12 years. A diagnosis of mutational voice disorder could be made, and the symptoms improved after training for a short period.In mutational voice disorder, it is important to make a diagnosis based on the time of its onset and the course of symptoms clarified by adequate examinations such as inquiry, and perform training.
