Abstract-Text Objective: Cricoid-Thyroid-Approximation (CTA) is a well-known surgical technique to elevate the pitch in Transwomen. The type of the Cricothyroid Joint (CTJ) directly influences the outcome of the pitch elevation which type A having the best outcome. Aim of this study was to analyse the stability of the pitch level of type A CTJ over a long period.

Methods/design: Between 2009 and 2018, 22 patients were treated with a CTA. In order to evaluate the CTJ type (type A vs type B/C) a pre- and postoperative HRCT scan was performed in all patients. Preoperatively, all patients underwent speech therapy. Middle speaking level (MSL) was measured before and after speech therapy, and, in addition, pre- and postoperatively (2 days, 30 days, 6 months and annually post-op).

Results: The mean of the MSLs before speech therapy was 117Hz (100-130Hz, SD 8Hz), 134Hz (110-160Hz, SD 13Hz) preoperatively, 206Hz (160-360Hz, SD 40Hz) postoperatively (2d, 30d, 6 month, 1 year), after 2years and 5 years in mean 210Hz (190-240Hz). In 21/22 patients a postoperative speech therapy was performed over 6 sessions.

Conclusions: This is the first study to analyse the outcome in the pitch level after CTA surgery in type A CTJ larynges over a long period. Our data shows that the outcome of type A CTJ is stable over a long period.
