- Type III Thyroplasty for Patients With High‐Pitched Voice Disorders: A Systematic Review and Meta‐analysis Bruno Dalla Vecchia Vendramini Lucas Marinho Siqueira Campos Bruno Teixeira de Moraes Silvio José de Vasconcelos Mateus Morais Aires Otolaryngology–Head and Neck Surgery AbstractObjectiveHigh‐pitched voice disorders can present notable social and professional obstacles for cisgender and transgender men. Our study aims to conduct a comprehensive meta‐analysis assessing the efficacy of type III thyroplasty, also known as relaxation thyroplasty, for different populations with high‐pitched voice disorders.Data SourcesA systematic literature review was conducted following Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines, searching Medline/Pubmed, Embase, Cochrane, Science Direct, Scielo, LILACS, and Google Scholar databases from inception to April 2024.Review MethodsStudies included patients undergoing type III thyroplasty for high‐pitched voice disorders. The primary outcome was the change in fundamental frequency postintervention. Subgroup analyses compared the following: (1) cisgender versus transgender populations, (2) primary versus secondary causes of high‐pitched voice disorders, and (3) unilateral versus bilateral vertical stripe resection techniques.ResultsThe initial search yielded 284 articles, 9 studies, including 69 unique patients, were included in the analysis. All studies provided level 4 evidence. Most patients were cisgender men with primary mutational dysphonia (66.7%, n = 46). The meta‐analysis showed a significant reduction in fundamental frequency after surgery, with a mean difference of −75.9 Hz (95% confidence interval [CI]: −91.5 to −60.3). Cisgender men and patients submitted to unilateral resection had higher preoperative fundamental frequency and showed a more pronounced reduction in fundamental frequency. There were no significant differences between primary and secondary mutational dysphonia.ConclusionType III thyroplasty effectively lowers vocal pitch in patients with high‐pitched voice disorders. The procedure is viable for both cisgender and transgender men, as well as for primary and secondary voice disorders. 10.1002/ohn.1185 http://onlinelibrary.wiley.com/termsAndConditions#vor
