目标/假设：突变性假声是一种功能性嗓音障碍，其特征是男性青春期前的高音不能过渡到青春期和成年期的低音。很少有客观的结果数据存在关于这种知之甚少的疾病的声音治疗的有效性。本研究探讨了一个单一的治疗会话使用手动喉reposuring作为一个主要的方法在突变falsetto.Study设计的直接影响：回顾性病例系列，pre-posttreatment.Methods：手动环喉技术，包括数字喉reposuring演习，被用来作为主要的方法来治疗12个连续的男性与突变falsetto. Study的主要方法（平均年龄17.5岁，14-25岁）。治疗前和治疗后的连接语音和持续元音样本的录音被提交到语音感知和声学分析，以评估一个单一的语音治疗会话的影响。使用倒频谱发音困难指数（CSID）计算连接语音和持续元音产生的严重程度的声学估计，CSID是一种多变量发音困难汇总工具，包含倒频谱和频谱测量。治疗前和治疗后的比较证实了一个显着的变化，在一个单一的治疗会话内的正常发声功能的方向为两个听众和CSID为基础的估计发声障碍的严重程度。由经验丰富的嗓音医生进行手动喉部重塑的行为治疗是治疗变异假声的有效方法。
Objectives/Hypothesis: Mutational falsetto is a functional voice disorder characterized by failure of the male high-pitched preadolescent voice to transition to the lower pitch of adolescence and adulthood. Few objective outcomes data exist regarding the effectiveness of voice therapy for this poorly understood disorder. This study examined the immediate effects of a single therapy session using manual laryngeal reposturing as a primary approach in the management of mutational falsetto.Study Design: Retrospective case series, pre-/posttreatment.Methods: Manual circumlaryngeal techniques, including digital laryngeal reposturing maneuvers, were used as the primary approach to treat 12 consecutive males with mutational falsetto (mean age 17.5 yrs., range 14-25 years). Pre- and posttreatment audiorecordings of connected speech and sustained vowel samples were submitted to auditory-perceptual and acoustic analysis to assess the effects of a single voice therapy session. Acoustic estimates of severity in both connected speech and sustained vowel productions were computed using the Cepstral Spectral Index of Dysphonia (CSID), a multivariate dysphonia summary tool that incorporates cepstral and spectral measures.Results: Pre- and posttreatment comparisons confirmed a significant change in the direction of normal vocal function within a single treatment session for both listener- and CSID-based estimates of dysphonia severity.Conclusion: Behavioral therapy using manual laryngeal reposturing by an experienced voice clinician is an effective and efficient primary approach for mutational falsetto.
