Laryngochondroplasty: A Systematic Review of Safety, Satisfaction, and Surgical Techniques

Background: Since first performed in 1975, two main surgical techniques for laryngochondroplasty have evolved: anatomical localization and direct endoscopic visualization. The aim of this study was to evaluate which method is safest and had the highest patient-reported satisfaction rates, and to determine whether these outcomes have changed over time.Methods: A systematic review and meta-analysis following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed to find and analyze all medical publications related to laryngochondroplasty. Of these studies, patients who underwent laryngochondroplasty for gender-affirmation surgery were evaluated. Surgical and patient-reported outcomes were compared between different surgical techniques and between studies before and after the year 2010.Results: A total of 226 patients have been reported to have undergone laryngochondroplasty for gender-affirmation surgery. Overall transient and long-term complication rates were 14% and 0%, respectively. A 97% satisfaction rate was reported overall. Endoscopic visualization techniques were associated with lower short-term complications (OR, 21.11; 95% CI, 7.56 to 58.93); there was no difference in long-term complications (OR, 7.81; 95% CI, 0.31 to 194.37) or patient satisfaction (OR, 5.73; 95% CI, 0.32 to 101.97). Studies performed before the year 2010 had a significantly greater number of short-term complications compared to studies performed after the year 2010 (OR, 10.16; 95% CI, 3.71 to 27.82), with no difference in long-term complications (OR, 4.56; 95% CI, 0.18 to 113.25) or patient satisfaction (OR, 4.99; 95% CI, 0.59 to 42.20).Conclusions: All laryngochondroplasty techniques result in high patient satisfaction. Endoscopic visualization may help facilitate safe surgery and should be used in conjunction with anatomical familiarity. Technique choice should be dictated by the surgeon's experience and patient desires.

Automated summary

Evaluated two main surgical techniques for laryngochondroplasty and found that endoscopic visualization is associated with lower short-term complications, with no difference in long-term complications and patient satisfaction. Studies performed before 2010 had significantly greater number of short-term complications, with no difference in long-term complications and patient satisfaction.
