Abstract
Purpose: to understand the impact of the chin tuck maneuver on swallowing function in individuals who underwent supracricoid laryngectomy with cricohyoidoepiglottopexy, and to identify clinical and sociodemographic factors associated with its effectiveness.
Methods: a longitudinal study was conducted with patients who underwent supracricoid laryngectomy, identified through the flow of videofluoroscopic swallowing studies performed between 2021 and 2023. Swallowing was assessed in two conditions — at rest and during the chin tuck maneuver — using the Penetration–Aspiration Scale (Rosenbek, 1996). Clinical and sociodemographic variables were collected from medical records. Associations between these variables and swallowing outcomes were analyzed using the Chi-square test, adopting a 5% significance level and calculating effect size (Cramer’s V).
Results: a total of 17 patients were included, predominantly older adults (88.2%), male (88.2%), married (64.7%), with low educational level (64.7%), smokers (76.5%), and alcohol users (52.9%). Most presented moderately advanced tumor stages (84.4%) and preservation of both arytenoids (70.6%). Silent aspiration occurred in 17.6% of cases and penetration in 23.5%. The response to the maneuver was heterogeneous, with functional improvement (29.4%), no change (52.9%), and worsening (17.6%). A non-significant trend was observed between maneuver effectiveness and educational level (p = 0.057; Cramer’s V = small effect).
Conclusion: the chin tuck maneuver showed a variable impact on swallowing, being effective only for part of the patients and not significantly associated with the analyzed clinical or sociodemographic variables.
