Introduction:
Wendler glottoplasty is a voice feminization surgical procedure designed to increase the fundamental frequency (F0) in male-to-female transsexual patients with gender dysphoria. On average, Wendler glottoplasty has the most significant effect on F0 among voice feminization surgical procedures.
Case Report:
We present the case of a young female patient with a testosterone-producing adrenocortical adenoma who underwent irreversible vocal changes secondary to virilization, which impacted her self-esteem and quality of life (QOL). Voice feminization surgery using Wendler glottoplasty was performed with significant improvement in F0 and QOL.
Discussion:
Sex hormones have a profound impact on the voice. Increased testosterone and dihydrotestosterone are known to cause hypertrophy of the laryngeal muscles and ligaments, which leads to a drop in F0. However, women who present androphonia rarely require surgical management and improve with vocal therapy alone. Few cases of voice feminization procedures for the treatment of androphonia have been described in the literature. Our patient presented with severe masculinization of her voice with a F0 lower than the average adolescent male, which led to the requirement of surgical management.
Conclusions:
Patients with severe androphonia that significantly affect their QOL and show no improvement after the management of the underlying pathology and intense vocal therapy are candidates for voice feminization surgeries. These procedures offer positive results both in terms of F0 and in improving patient's self-esteem and QOL.
