Evaluating Patient Benefit From Laryngochondroplasty.

Objectives/hypothesis: To elucidate and review current literature on the surgical technique for laryngochondroplasty in male-to-female transgender patients. To determine the degree of benefit afforded to male-to-female transgender patients by laryngochondroplasty using the Glasgow Benefit Inventory (GBI).

Study Design: Retrospective case series.

Methods: After institutional review board approval was obtained, the GBI survey was given to patients who underwent laryngochondroplasty by the author. Demographic information was analyzed including age, race, wait time to surgery, distance traveled, median zip code income, and concomitant gender-affirming surgeries such as vaginoplasty, breast augmentation, or facial feminization.

Results: From April 2016 to April 2020, 209 patients received laryngochondroplasty within the Kaiser Permanente Northern California Medical System. Of those, 91 received laryngochondroplasty with the author and were given the GBI, with 73 patients (80%) responding. Patients were on average 31.4 years old, traveled 45.4 miles to the surgical site, lived in a zip code with a median income of $86,793.61, and waited 95.7 days for surgery. Patients had a statistically significant improvement in all three subscores (general, social, and physical) of the GBI as well as in their overall score.

Conclusions: Laryngochondroplasty is a safe and effective procedure to reduce thyroid cartilage prominence (Adam's apple) in male-to-female transgender patients. There was a statistically significant improvement in the overall score and all subscores of the GBI after laryngochondroplasty LEVEL OF EVIDENCE: 4 Laryngoscope, 130:S1-S14, 2020.
