Assessing the concern for airway complications introduced by Wendler's glottoplasty

Objective

Wendler's glottoplasty (WG) is a pitch-elevating surgery performed by laryngologists providing gender-affirming care. The surgery creates an anterior glottic web that could theoretically cause airway concerns, either perioperatively or at the time of future procedures; such concerns are not well-described in the literature. We seek to assess surgeon opinions on airway concerns regarding WG.

Method

A survey of laryngologists assessing opinions on airway considerations in glottoplasty.

Results

A total of 19 physicians responded, representing approximately 193 surgeries. 52.6% performed glottoplasty and the remainder responded based on experience with anterior glottic webs. Two perioperative airway complications were reported, both mild stridor that did not prevent same-day discharge. No long-term sequela was reported. All surveyed laryngologists endorsed an altered general anesthetic approach for future procedures, with 73.7% advocating for use of a smaller endotracheal tube. 72.2% did not have "major concerns" about future intubations, and only 5.3% thought the immediate risk of airway compromise was a "real concern." 91.9% counsel their patients routinely but briefly on airway concerns. Open-ended comments conveyed themes of concern for post-operative disruption of the web more than of airway compromise.

Conclusion

Because glottoplasty is performed in the anterior glottis and does not significantly impact airway patency, the risk of serious airway complications appears to be minimal. Laryngologists believe future intubations require a modified approach with a smaller tube, partly due to concern for glottic web trauma. Based on this pilot study, the topic deserves greater work to standardize care and anesthetic alterations for patients with WG.

1-Year Results of Combined Modified Wendler Glottoplasty with Voice Therapy in Transgender Women

BACKGROUND

To date, 1-year evaluation of pitch elevation in patients undergoing modified Wendler glottoplasty (WG) in combination with VT has not been assessed.

OBJECTIVES

To determine whether 1-year pitch elevation is sustained in patients who undergo modified WG in combination with VT for voice feminization.

METHODS

A retrospective review of patients who underwent WG in combination with voice therapy (VT) was performed from 2016 to 2020. Charts were reviewed for sustained vowel fundamental frequency (F0/a/), speaking fundamental frequency (SF0), and Trans Woman Voice Questionnaire (TWVQ) at preoperative, initial postoperative (3-6 months after surgery), and 12-month postoperative visits.

RESULTS

Change in average F0/a/, SF0 and TWVQ was 50.25 Hz, 32.96 Hz, and 32.6 at 12-months postoperatively compared to preoperative values. Initial and 12-month postoperative SF0 were significantly higher than preoperative SF0 (Mann-Whitney U test p = 0.0042, p = 0.0010). There was no difference in initial postoperative and 12-month postoperative SF0 (p = 0.50). TWVQ at 12 months was significantly lower than preoperative TWVQ (ANOVA p < 0.001, Tukey honestly significant difference HSD p < 0.05).

CONCLUSIONS

Pitch elevation remains sustained at one year in patients undergoing modified WG in combination with VT. Modified Wendler glottoplasty combined with VT results in relatively long-term improvements in voice-related quality of life and is possibly a beneficial addition in the long-term management of patients who desire voice feminization.
