Trans Woman Voice Questionnaire Scores Highlight Specific Benefits of Adjunctive Glottoplasty With Voice Therapy in Treating Voice Feminization.

Treatment options to assist patients to produce a more perceptually feminine voice include voice therapy (VT) and surgeries to elevate pitch such as the Wendler glottoplasty (WG). The Trans Woman Voice Questionnaire (TWVQ) is a validated quality of life measure for trans women's self-reported perceptions of their voice and is frequently administered before and after such interventions. The 30 statements broadly pertain to how feminine a patient feels their voice is, how effortful it is to produce their voice, and how their voice impacts them psychosocially, making it a useful and specific outcome measure when treating trans females for voice concerns. To compare quality of life outcomes between VT and VT with adjunct WG (VT+WG) based on changes in ratings of individual statements on the TWVQ. A retrospective case series of 31 trans female patients treated was completed. A total of 17 patients underwent VT and 14 underwent VT with adjunctive WG. Ratings for each of the 30 TWVQ statements were compared before and after treatment for each group. Wilcoxon rank-sum tests were used to compare rating changes before and after treatment. Spearman rank-order correlation tests were used to assess the association between total TWVQ score and "current voice" rating. WG was associated with statistically significantly improved ratings for every statement on the TWVQ except one. In contrast, VT was associated with statistically significant improvements in 16 of the 30 statements, which largely pertained to patient emotions surrounding their voice rather than physical aspects such as pitch and dysphonia. Furthermore, while both WG+VT and VT improved the "current voice" rating significantly, WG improved the score by nearly 1 unit more. Lastly, we found a positive association between the total TWVQ score and current voice rating, indicating that lower scores were associated with more self-perceived feminine-sounding voices (P < 0.01). Both VT and VT+WG result in improvements in the TWVQ. The specific statements on the TWVQ offer insight into specific quality of life treatment outcomes, with VT associated with improvements in mostly psychosocial aspects of voice production and VT+WG with both psychosocial and physical aspects.
