“…Para análise dos resultados, o fechamento glótico foi dividido, em: "normal" e "alterado". O fechamento glótico normal incluiu o fechamento glótico completo e a fenda triangular grau I, comum na população feminina e considerada uma inadaptação fônica, sem interferência na fonação (Dedivitis, 2002;Cielo, Schwarz, Finger, Lima, & Christmann, 2019). O fechamento foi considerado "alterado" para outros tipos de fendas com ou sem presença de patologias laríngeas.…”

“…Situações fisiológicas devem ser reconhecidas, como a presença de pequena fenda triangular grau I. Este tipo de fenda é considerado "normal" no sexo feminino, uma vez que se limita à glote intercartilagínea não se estendendo ventralmente ao processo vocal das aritenoides (Dedivitis, 2002). Portanto, a aproximação das cartilagens aritenoides não é completa, criando uma fenda glótica posterior à fonação restrita à área respiratória, não interferindo na produção vocal (Cielo et al, 2019).…”

Objective: to verify the videolaryngostroboscopic characteristics of teachers with vocal complaints. Methods: 32 teachers with a mean of 39.15 years old underwent a medical examination of videolaryngostroboscopy. Videolaryngostroboscopies were evaluated by consensus and simultaneously by three otorhinolaryngologists using a specific protocol. Data were analyzed descriptively and by Spearman's Correlation test, with a significance level of 5% (p≤0.05). Results: most teachers had normal glottic closure (65.62%). All of them presented: high symmetry of vocal fold vibration (92.18%), high amplitude of mucosal wave vibration (90.31%), and high presence of mucous wave (90.93%). There was a significant positive correlation between normal glottic closure and amplitude of vibration (p=0.008) and between amplitude of vibration and mucosal wave (p=0). There was a significant negative correlation between altered glottic closure and amplitude of vibration (p=0.003); between altered glottic closure and normal closure (p=0); and between symmetry of vibration and global constriction of the laryngeal vestibule (p=0). Conclusion: the majority of teachers, even with vocal complaints and some with the presence of vocal nodules, had normal glottal closure and all had averages above 90% in the parameters: symmetry of vocal fold vibration, amplitude of mucosal wave vibration, and presence of mucous wave. In this group, the greater the normal glottic closure, the greater the amplitude of vibration of the mucous wave, and what the greater the presence of the wave, and the less the global constriction of the laryngeal vestibule, the greater the symmetry of vocal fold vibration.

“…Além disso, o sistema respiratório apresenta relevância no processo da produção vocal devido à pressão do ar expirado ser a fonte ativadora e reguladora da emissão (Pinho, 2003;Behlau, Madazio, Feijó, & Pontes, 2013;Genilhú& Gama, 2018;Cielo, Schwarz, Finger, Lima, &Christmann, 2019).

Entre essas medidas existem os tempos máximos de fonação (TMF), suas relações, e os níveis de pressão sonora (NPS) (Miglioranzi, Cielo, & Siqueira, 2012;Oliveira et al, 2013;Genilhú & Gama, 2018).…”

The objective of the work was to characterize the aerodynamic vocal measurements of professional singers according to gender and the reference values. This is a cross-sectional, quantitative and retrospective study with 23 professional singers between 19 and 55 years old. The maximum phonation times of /a/, /i/, /u/, /s/, /z/, /e/, /ė/; sound pressure levels; and s/z and ė/e ratios were analyzed. The data were analyzed statistically. Men showed maximum phonation time of /e/, /i/ and /u/ significantly below the reference values and women showed significantly lower values of the maximum phonation time of /e/, and maximum phonation time of /i/ e /u/ significantly within the expected. The usual sound pressure level and maximum sound pressure level were significantly higher than the reference values in both genders. It was concluded that, in the group of professional singers analyzed, the results of the maximum phonation time suggest greater incoordination in the respiratory and laringeal control of the prolonged emission in men. The results of sound pressure level suggest greater vocal effort in the emission for both genders, or adjustments due to the muscular training inherent to the profession.

“…However, it is not always possible to visualize episodes, which further complicates the diagnosis. 9 Therefore, most PVFM diagnoses are diagnoses of exclusion based on history 8 and nonspecific signs such as expiratory posterior glottal gap 10,11 and cannot be definitively confirmed. 12 Lack of understanding of PVFM among clinicians leads to higher healthcare utilization and associated costs.…”

Objectives Paradoxical vocal fold movement (PVFM) is often misdiagnosed as asthma and tends to have a prolonged time to diagnosis. Study aims were to estimate the time from dyspnea onset to PVFM diagnosis, to estimate associated pre‐ and postdiagnosis direct and indirect healthcare cost, and to compare the cost of postdiagnosis care among patients who did and did not undergo standard‐of‐care speech therapy. Methods Patients diagnosed with PVFM were identified retrospectively. Time from dyspnea symptom onset to diagnosis was measured. Direct costs consisting of office visits, procedures, and prescribed pharmaceuticals before and after diagnosis were calculated. Indirect costs associated with lost wages related to healthcare were also estimated. Costs for patients who initiated versus did not initiate speech therapy and who had successful versus unsuccessful therapy were compared. Results Among 110 patients, median time from dyspnea onset to PVFM diagnosis was 33 months (interquartile range [IQR] 5–60). Direct and indirect prediagnosis median costs were $8,625 (IQR $1,687–$35,812) and $736 (IQR $421–$1,579) while first year following dyspnea symptom onset median direct and indirect costs were $1,706 (IQR $427–$7,118) and $315 (IQR $131–$631). Median direct and indirect costs of care in the postdiagnosis year were $2,062 (IQR $760–$11,496) and $841 (IQR $631–$1,261). Pharmaceuticals were predominant cost drivers in all time periods. Of those who completed speech therapy, 85% had breathing symptom improvement while incurring significant cost savings compared to those whose symptoms persisted. Conclusion Costs of care leading to diagnosis of PVFM are substantial. More efficient methods of identifying patients with PVFM are essential to reduce prolonged time to diagnosis and associated costs. Level of Evidence NA Laryngoscope, 132:142–147, 2022
