ObjectivesGains in pitch from gender affirming voice training (GVT) alone in trans women have historically been shown to decline after 1 year. Currently no standard exists for length and type of GVT that yields meaningful behavioral change and patient satisfaction with voice outcomes in trans women. This study aims to determine whether GVT alone leads to sustained pitch elevation and patient satisfaction in trans women.MethodsRetrospective review from 2016 to 2020 of trans women patients who underwent GVT alone for voice change. Charts were reviewed for acoustic analysis of pitch including sustained vowel fundamental frequency, speaking fundamental frequency, and quality of life data from the Trans Woman Voice Questionnaire at pre‐therapy, immediate post‐therapy, and extended post‐therapy time intervals.ResultsA total of 157 patients presented to our Voice Center, of which 34 participated in the full course of GVT. Patients underwent an average of six sessions of GVT (range 5–7) over an average of 13.14 weeks (range 6–16). Average time between completing GVT and presenting for extended follow‐up was 11.37 months (range 6–31). Compared to initial presentation prior to therapy, at extended follow‐up after completing GVT average change in F0/a/, SF0, and TWVQ were 64.6 Hz, 31.3 Hz, and 32.45. No significant change was noted between immediate post‐therapy and extended post‐therapy acoustic measures. TWVQ demonstrated continued improvement between immediate post‐therapy and extended post‐therapy.ConclusionsIn self‐selected patients who present for extended follow‐up, GVT alone can result in sustained pitch elevation and voice‐related quality life in trans women.Level of Evidence4 Laryngoscope, 133:2340–2345, 2023
