Endoscopic vocal fold shortening (EVFS) remains a cornerstone of gender-affirming voice surgery. However, achieving consistent fundamental frequency (F0) gains often poses a challenge for phonosurgeons. Recent research highlights that anterior glottoplasty pitch elevation depends significantly on the three-dimensional geometry of the surgical web, particularly the inclusion of the infraglottic vibratory surface.
Traditional techniques usually focus on the anterior-posterior (AP) dimension of the vocal fold web. This new study utilized an ex vivo porcine model to compare "thin" webs with "thick" webs. Thin webs captured only the superior free edge of the vocal fold. Conversely, thick webs involved sutures that captured the entire infraglottic vibratory surface at the same AP position.
The results showed a clear distinction in performance. While thin webs raised the pitch to a mean of 535.1 Hz, they exhibited high interspecimen variability. Thick webs produced a much more consistent and significant elevation, reaching 652.0 Hz. Consequently, the data suggests that capturing the infraglottic surface is a technically modifiable variable that can optimize surgical results.
The study demonstrates that the craniocaudal dimension of the web is critical. By incorporating more of the infraglottic surface, surgeons effectively reduce the vibrating mass more predictably. Moreover, this leads to a stable and significant increase in fundamental frequency. For otolaryngologists in India performing gender-congruent procedures, these insights provide a clear path toward better-standardized outcomes. Furthermore, deliberate infraglottic capture may reduce the necessity for revision surgeries by providing more reliable pitch gains during the initial procedure.
A thick web incorporates the infraglottic vibratory surface, which provides a more consistent and significant increase in fundamental frequency compared to thin webs that only capture the superior edge.
It modifies the three-dimensional geometry of the vocal fold more effectively. This reduction in the vibrating mass leads to a more predictable and higher pitch elevation in gender-affirming surgery.
While the study used a porcine model, the physical principles of vocal fold vibration are similar. Surgeons can apply these geometric principles to optimize outcomes in human endoscopic vocal fold shortening.
