Abstract

Introduction: In different diseases, the complaint is a determining factor and can contribute as a marker for early screening and diagnosis. Objective: This study aimed to relate the complaint of swallowing difficulties with pharyngeal findings and to compare different neurological diseases in adults. Method: Retrospective, observational, cross-sectional clinical study using a convenience sample. For this study, 101 medical records of individuals with neurological diseases, regardless of sex, age or time/stage of the disease, referred to a Reference Center for the diagnosis of oropharyngeal dysphagia were analyzed. Individuals with more than one underlying etiology, without both clinical and videoendoscopic swallowing assessments and with no swallowing complaints were excluded. Eighty-nine individuals with complaints of swallowing difficulties were included, divided into three groups: group 1 composed of 40 individuals with cerebrovascular accident - CVA (G1), group 2 of 30 individuals with Parkinson's Disease - PD (G2) and group 3 composed of 19 individuals with Amyotrophic Lateral Sclerosis - ALS (G3). Complaints of difficulty in swallowing were categorized into impairment of efficiency (C1), safety (C2) of swallowing, or both concomitantly (C3). Swallowing videoendoscopy was performed with service protocol through standardized food consistencies and volume. The categories and types of swallowing complaints were related to the findings of posterior oral leak, pharyngeal residues and laryngotracheal penetration/aspiration between the groups. Statistical analysis was performed using the Chi-Square Test. Results: Complaints of swallowing difficulties were more frequent in category C3, regardless of the group. The most frequent complaint in C1 was difficulty with food consistency in all groups, in C2 the choking complaint was the most frequent in all groups and C3 had a higher frequency of "one complaint per category" in G1 and G2 “more than one complaint per category” was frequent, in G3 “one complaint per category” and “more than one complaint per category” presented the same frequency. There was a relationship between complaint categories and posterior oral leakage in all groups. When comparing the categories between the groups with the pharyngeal findings, there was a relationship between C1 and C3 in groups G1 and G3, between C2 and C3 in G2 for EOP. There was no relationship between types of complaint and pharyngeal findings. Conclusion: Complaints of swallowing difficulties in Post-CVA subjects, with Parkinson's Disease or with Amyotrophic Lateral Sclerosis and oropharyngeal dysphagia were more frequent in the efficiency and safety of swallowing concomitantly. Posterior oral leakage was the only pharyngeal finding present in all categories of complaints, regardless of the group. There was no difference in the relationship between the types of complaints of swallowing difficulties and pharyngeal findings between the groups. (AU)
