Abstract: Although there is a close relationship between swallowing and breathing are no studies that relate to atypical swallowing radiographic anatomy of the airway space and its possible correlation with the radiographic position of the hyoid bone. The aim was to evaluate the possible correlation with the radiographic position of the hyoid bone and airway space in lateral radiographs of children with atypical deglutition. Using cephalometric analysis on lateral teleradiographs, the distances of H-MP (hyoid to mandibular plane) and H-T (hyoid to tuber) were Spearman's correlation analysis was performed with PAS (airway space) in two groups: the experimental group with atypical deglutition and the control group normal deglutition. Both groups included subjects in mixed dentition stage. Thevariable T-H had statistically significant correlation with PAS (0.0286) and the variable MP-H had significant correlation with variable PAS (0.0053). Ourresults show that advanced positive correlation of the radiographic position of the hyoid bone to the airway space only in the group of normal swallowing. The lower airway in patients with atypical swallowing, causing changes in tongue posture which leads to change in the position of the hyoid bone. Aunque existe una estrecha relación entre la deglución y la respiración, no se dispone de estudios que relacionen la anatomía radiográfica atípica de deglución del espacio de la vía aérea y su posible correlación con la posición radiológica del hueso hioides. El objetivo fue evaluar la posible correlación de la posición radiológica del hueso hioides y las vías aéreas en radiografías laterales de ni os con deglución atípica. Utilizando el análisis cefalométrico sobre telerradiografías laterales, fueron analizadas las correlaciones entre las distancias H-MP (hueso hioides al plano mandibular) y HT (hioides al tubérculo) y el PAS (espacio de la vía aérea) en dos grupos: el grupo experimental con la deglución atípica y el grupo control con deglución normal. Ambos grupos estaban en etapa de dentición mixta. Las variables HT y MP-H tuvieron una correlación estadísticamente significativa con la variable PAS, 0,0286 y 0,0053 respectivamente. Nuestros resultados muestran que la correlación positiva de la situación radiológica avanzada del hueso hioides al espacio de las vías respiratorias sólo se observa en el grupo de deglución normal. La vía respiratoria inferior en los pacientes con deglución atípica provoca cambios en la postura de la lengua, lo que conduce a un cambio en la posición del hueso hioides.

Abstract: This study describes preliminary laryngeal electromyography (LEMG) data and botulinum toxin treatment in patients with dysphonia due to movement disorders. Twenty-five patients who had been clinically selected for botulinum toxin administration were examined, 19 with suspected laryngeal dystonia or spasmodic dysphonia (SD), 5 with vocal tremor, and 1 with Gilles de la Tourette syndrome (GTS). LEMG evaluations were performed before botulinum toxin administration using monopolar electrodes. Electromyography was consistent with dystonia in 14 patients and normal in 5, and differences in frequency suggesting essential tremor in 3 and Parkinson tremors in 2. The different LEMG patterns and significant improvement in our patients from botulinum toxin therapy has led us to perform laryngeal electromyography as a routine in UNICAMP movement disorders ambulatory.
