ABSTRACT
Objective: To compare subglottic pressure in patients with oropharyngeal dysphagia before and during the chin tuck maneuver.Materials and Methods:: A cross-sectional, quasi-experimental, prospective and comparative study was carried out from January 2020 to December 2021, which records of patients with oropharyngeal dysphagia according to Cámpora, from the Phoniatrics service, National Institute of Rehabilitation Luis Guillermo Ibarra Ibarra, Mexico City. Subglottic pressure was measured before and during compensation maneuver with a non-invasive recording system. Statistical analysis was performed with the SPSS V. 25 program.
Results: Seventy-seven patients with an average age of 54.1 years were studied, most with mild (59.7%) or moderate (33.8%) dysphagia. Subglottic pressure values were significantly higher during the chin tuck maneuver (20.28 vs 23.12 cm H2O, Z = -6.010, p ‹ 0.001). The difference between subglottic pressure with and without maneuver was negatively correlated with weight (p = -0.362, p = 0.001) and height (p = -0.308, p = 0.006), and it was higher among the group of patients with severe dysphagia (H = 7.987, gl = 2, p = 0.018). Principal component analysis and discriminant multivariate showed the inverse relationship between somatometric variables and subglottic pressures. Subglottic pressure increased significantly in patients when performing the chin tuck maneuver.
Conclusions: The chin tuck maneuver significantly increases subglottic pressure in patients with oropharyngeal dysphagia. Our results show that normal body mass index values, neck circumference and abdominal diameter favor the generation of higher subglottic pressure.
