“…The Perception Post-intervention form also indicated that the majority of teachers reported moderate to intense for clearer voice and moderate to intense for ease of speaking. These results are consistent with other studies that investigated the Perceived Effects Post-intervention and the effects of surface hydration with saline solution (0.9% NaCl) on voice quality [12][13][14]16,17 .…”

“…Another Brazilian study that aimed to compare the effects of two protective strategies ─ voice amplification (VA) and 0.9% NaCl nebulization (NEB) ─ on teachers' voice in the work setting showed that VA and NEB may help mitigate dysphonia in different pathways, being potential interventions for protecting teachers' voices 14 .…”

Objective: to assess the effects of surface hydration on vocal quality according to teachers’ self-perception. Methods: an examiner-blinded pre-test and post-test intervention study carried out with a single group of 27 teachers. Sociodemographic characteristics and work questionnaire, Screening Index for Voice Disorder, Vocal Severity Rating Scale, Expected Effects Pre-intervention, Perceived Effects Post-intervention and Post-intervention Perception instruments, were applied. The intervention lasted 4 weeks and consisted of 5 minutes of nebulization with saline solution (sodium chloride 0.9%), after 10 minutes of mouth dehydration, prior to teaching. Results: screening Index for Voice Disorder scores demonstrated a statistically significant reduction (p=0.001). Frequency of voice disorders in the Vocal Severity Rating Scale was reduced without a statistical significance (p= 0.172). Expected Effects, Pre-intervention, and Perceived Effects, Post-intervention, showed improvement in vocal quality (40.7%), vocal comfort (40.7%) and vocal folds hydration (37%). Post-intervention perception form showed moderate improvement of the symptoms (59.3%), cleared voice (55.6%) and ease speaking (48.1%) as well as intense belief in the intervention (74.1%) and intense compliance to the intervention (74.1%). Conclusion: surface hydration with saline solution promoted self-perceived improvement in vocal quality.

“…They found better voice quality after adequate surface hydration. 16 Adequate hydration of the body is considered to be 2 liters or eight glasses of water 17,18 and agents that dehydrate the body result in decreased laryngeal hydration and thick secretions, which may block the ductal system of seromucinous glands with a resultant formation of a mucous retention cyst. We considered laryngeal hydration to be poor when a person consumed less than or equal to four glasses of water a day or consumed more than 8 caffeinated beverages (tea/coffee/cola) in a day.…”

A 10‐year study of the etiopathogenesis of cysts with a study of seromucinous glands in vocal folds

Objective An increasing number of vocal fold cysts excised, as compared to polyps, over the last decade led us to review these cases. We found a statistically significant increase in cysts excised as compared to polyps, over the latter 5‐year period (2013–2017). This prompted us to analyze possible factors responsible for this increase. We also performed a histological study of the normative distribution pattern of seromucinous glands in the apparently normal vocal folds. Methods A retrospective review of all cysts and polyps excised over a 10‐year period was performed. Patient demographics, air‐pollution levels, videostroboscopic findings and histologic analysis of pathology were reviewed. Findings were compared between the initial and latter 5‐year period of all cysts excised. The second part of the study entailed a histological study of the presence and distribution pattern of seromucinous glands in 40 apparently normal fresh frozen cadaver vocal folds. Results There was a statistically significant (P = .035) increase of mucous retention cysts excised as compared to polyps over the latter 5‐year period. Decreased laryngeal hydration was a significant associated finding in cysts excised over the decade as compared to polyps. Striking zone lesions, suggestive of vocal abuse, were seen in a majority of patients of both polyps and cysts excised over the decade. Air pollution had significantly increased in India over the latter 5‐year period. Vocal fold histology in cadavers revealed a presence of seromucinous glands in 32.50% (13/40) with 25.00% (10/40) present in the Superficial Lamina Propria (SLP). Conclusion Decreased laryngeal hydration, vocal abuse and mucous glands present in the SLP may be predisposing factors towards mucous retention cyst formation. An increase in number of these cysts excised over the latter 5‐year period was seen as was increased air pollution.
