Indeed,

too many HIGH QUALITY Surgeons in this Field ( yet ).
Somyos Kunachak proposed an open laryngoplasty to alter pitch
(Kunachak S, Prakunhungsit S, Sujjalak K (2000)
Thyroid cartilage and vocal fold reduction:
a new phonosurgical method for male-to-female transsexuals.
Ann Otol Rhinol Laryngol Nov; 109(11):1082-6).
This procedure reduced the size of the larynx
to a more female size in its cross sectional
dimension and shortened the length of the
vibratory vocal fold. It possibly tensioned the vocal fold.
