The elegant studies of Hirano, Kurita, and Nakashima (1983)  provide much insight into the development of the phonatory larynx. They studied 88 normal larynges in patients whose ages ranged from a few hours after birth to 69 years old. Several gross anatomic and histologic variables were studied. The length of the entire vocal fold, the length of the membranous portion (anterior fold) and the cartilaginous portion (posterior fold including vocal process and arytenoid) were measured. It was found that up to the age of 10 years, the length of the vocal fold did not vary much between boys and girls. At 10 years up to 20 years of age, the length of the membranous portion of the vocal fold gradually increased for males.
