Abstract
Type I Chiari malformation (MCI) is a generally congenital condition of herniation of the cerebellar tonsils below the foramen magnum, which can lead to compression of structures close to the posterior cranial fossa or obstruction of the flow of ventral cerebrospinal fluid. Type I, although rare, is the most commonly found in the population. This study aimed to report the findings of video endoscopy of swallowing, speech assessment, level of oral intake, nutritional risk and therapeutic planning in three cases of Type I Chiari malformation. Data were collected regarding the assessment of mobility and strength of tongue, Maximum Phonation Time (MPT), cough efficiency and the Eichner Index. The level of oral intake and pharyngeal signs of dysphagia were analyzed in four food consistencies, according to the International Dysphagia Diet Standardization Initiative (IDDSI) classification, using swallowing video endoscopy. For analysis and classification of pharyngeal residues, the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS) was used, while the Malnutrition Screening Tool (MST) was used to track nutritional risk. Reduced tongue mobility and strength and reduced MPT were observed, while pharyngeal signs varied between cases, with the presence of incomplete glottic closure, posterior oral escape, multiple swallows, pharyngeal residues and laryngeal penetration.
