Voice Outcome of Glottoplasty in Trans Women

Impact of Wendler glottoplasty on acoustic measures and quality of voice in transgender women: a systematic review and meta-analysis

PURPOSE

Since new evidence regarding the impact of Wendler glottoplasty (WG) on the voice in transgender women became available in the literature in recent years, we aimed to perform an updated systematic review and meta-analysis to determine the actual safety and efficacy of WG in the process of vocal feminization.

METHODS

PubMed, Embase, and Cochrane were searched for English-language articles published until July 4, 2023. Studies were found eligible if they evaluated the impact of WG on the acoustic-aerodynamic measures and quality of voice in transgender women.

RESULTS

Twenty-three studies were identified. After exclusion of three studies due to incomplete data, 20 studies including 656 patients were included in the meta-analysis. After WG, there was a significant increase of fundamental frequency, speaking fundamental frequency, and lower limit of the frequency range (p < 0.001). Concurrently, a significant reduction of frequency range and maximum phonation time was observed (p < 0.001). No significant differences were found between the pre- and postoperative values regarding the Grade, Roughness, Breathiness, Asthenia, and Strain scale score (p = 0.339). The overall score in the Trans Woman Voice Questionnaire (TWVQ) significantly improved after WG (p < 0.001).

CONCLUSIONS

WG is an effective voice feminization method in transgender women, associated with a high procedural success and low risk of postoperative complications. Significantly improved TWVQ score after surgery suggests its positive impact on the voice-related quality of life. Postoperative decrease of maximum phonation time and frequency range does not seem to significantly impact the effectiveness of voice production.

Accuracy Analysis of the Multiparametric Acoustic Voice Indices, the VWI, AVQI, ABI, and DSI Measures, in Differentiating between Normal and Dysphonic Voices

The study aimed to investigate and compare the accuracy and robustness of the multiparametric acoustic voice indices (MAVIs), namely the Dysphonia Severity Index (DSI), Acoustic Voice Quality Index (AVQI), Acoustic Breathiness Index (ABI), and Voice Wellness Index (VWI) measures in differentiating normal and dysphonic voices. The study group consisted of 129 adult individuals including 49 with normal voices and 80 patients with pathological voices. The diagnostic accuracy of the investigated MAVI in differentiating between normal and pathological voices was assessed using receiver operating characteristics (ROC). Moderate to strong positive linear correlations were observed between different MAVIs. The ROC statistical analysis revealed that all used measurements manifested in a high level of accuracy (area under the curve (AUC) of 0.80 and greater) and an acceptable level of sensitivity and specificity in discriminating between normal and pathological voices. However, with AUC 0.99, the VWI demonstrated the highest diagnostic accuracy. The highest Youden index equaled 0.93, revealing that a VWI cut-off of 4.45 corresponds with highly acceptable sensitivity (97.50%) and specificity (95.92%). In conclusion, the VWI was found to be beneficial in describing differences in voice quality status and discriminating between normal and dysphonic voices based on clinical diagnosis, i.e., dysphonia type, implying the VWI's reliable voice screening potential.

Characterizing Gender-Affirming Voice Intervention Discussion on Social Media: A Cross-Platform Analysis

OBJECTIVES

Gender-affirming voice treatments, such as voice training and surgery, are highly impactful for transgender patients experiencing vocal dysphoria and may be discussed on social media platforms including Twitter and Reddit. Our goal was to characterize the content and sentiment of social media posts pertaining to gender-affirming voice interventions to better understand the needs of this patient population.

STUDY DESIGN

Retrospective data-mining study.

METHODS

A total of 18,695 Tweets from 2001 to 2021 and 23,742 r/Transvoice Reddit submissions and comments from 2009 to 2020 were extracted via publicly available application programming interfaces and analyzed using language processing and sentiment analysis techniques. One thousand eighty-six highly emotive r/Transvoice posts related to voice modification treatments were manually reviewed for further classification.

RESULTS

Online discussion of gender-affirming voice has increased over time and is centered on vocal feminization. Recurrent themes included use of online training resources, singing voice, and barriers to care such as cost and variable experiences with health care providers. Sentiment analysis demonstrated that posts discussing gender-affirming voice training had higher average sentiment scores than those discussing voice surgery, on both Twitter (0.252 vs 0.161; P < 0.001) and Reddit (0.349 vs 0.301; P < 0.001). Frequently appearing themes in highly negative surgery posts included mixed outcomes (9.3%), surgical complications (9.3%), and recovery time (8.5%). Common themes shared by the positive subgroup analysis included peer support, vocal quality, and importance of practice.

CONCLUSIONS

Gender-diverse patients share various concerns and resources relating to voice intervention in the online communities of Twitter and Reddit. The discussion has been growing over the past decade and is mostly positive, with significant social support and resource-sharing within the community. Aggregated online sentiment toward gender-affirming voice surgery is more negative than voice training, largely due to concerns about surgical outcomes and variability, risks, and recovery period.
