RESUMO
Introduction: Chondrolaryngoplasty or "tracheal shaving" is cosmetic surgery to reduce the laryngeal prominence in transgender women. Complications may include damage to the vocal folds and epiglottic destabilization or aesthetic dissatisfaction. Objective: To assess and compare acoustic and perceptual voice outcomes and aesthetic satisfaction of transgender women submitted to chondrolaryngoplasty. Methods: Prospective interventional cohort of transgender women submitted to chondrolaryngoplasty between March 2018 and October 2019. Voice analysis included simple-blind application of the GRBAS Hirano scale by speech therapist and measurement of the fundamental frequency, in the preoperative and 1-month postoperative periods. The visual analog scale was used to analyze the aesthetic satisfaction, before and 6-months after chondrolaryngoplasty. Results: Fifteen patients participated, with a mean age of 31.7 ± 8.3 years (range 22-51 years). The mean postoperative follow-up period was 15.3 ± 6.1 months (range 6-25 months). There was a significant improvement in the visual analog scale for aesthetic satisfaction, with a preoperative mean = 0.7 ± 1.0 and a postoperative mean = 9.3 ± 1.1 (95% CI for difference = 7.3 to 9.6; p < 0.001). All patients presented a positive variation. The preoperative mean fundamental frequency was 171.3 ± 41.2 Hz and the postoperative, 177.1 ± 39.5 Hz, with no statistical significance (95% CI for difference = -30.1 to 41.7; p = 0.74). There was no statistically significant difference in the pre- and postoperative comparison of each component of the GRBAS scale. One (7%) patient presented a hyperpigmented scar and 2 (13%) reported hoarseness during the first postoperative week. There were no major complications such as disinsertion of the epiglottis or vocal folds. Conclusion: Chondrolaryngoplasty led to significant aesthetic satisfaction in transgender women. The surgery caused no noticeable vocal change in pitch or perception.
RESUMO
UNLABELLED: Dystonia is a central motor processing neurological disorder characterized by abnormal, often action-induced, involuntary movements or uncontrolled spasms. AIM: To compare patients with the diagnoses of focal and segmental adductor laryngeal dystonia at the Neurolarynx Outpatient Clinic of the Federal University of São Paulo. MATERIALS AND METHODS: A clinical retrospective study of data collected from patient registries from 2003 to 2009. RESULTS: Of 34 patients, 25 presented focal dystonia and 9 presented segmental dystonia. There were 30 females (88. 2%) and 4 males (11. 8%). A relation with a traumatic event was reported in 11 cases (32. 4%). Vocal tremor was observed in 21 patients (61. 8%). The mean age at onset, the age at diagnosis, and time between the onset and the diagnosis were respectively 55, 61. 3 and 6. 3 years. There was no statistical difference between patients with focal laryngeal adductor dystonia and segmental dystonia in the study data. CONCLUSIONS: There were no statistical differences among patients with focal adductor laryngeal dystonia and segmental dystonia relating to age of onset, age of diagnosis, gender, time between onset and diagnosis, presence of associated tremor, and relation to trauma.
