Por qué importa

Este estudio publicado en Sleep Science evalúa la eficacia de los dispositivos de avance mandibular (MAD) a medida para el tratamiento del ronquido primario y la apnea del sueño. Se analizaron los cambios anatómicos en la vía aérea faríngea mediante tomografía computarizada y su correlación con la mejora clínica, medida por polisomnografía y la escala de somnolencia de Epworth. Los resultados indican un aumento del calibre de la vía aérea en la mayoría de las mediciones, siendo significativas en el paladar duro sagital y la zona supraglótica axial. La mayoría de los pacientes experimentaron control del ronquido y disminución de la somnolencia diurna. Estos hallazgos son relevantes para el odontólogo al considerar el MAD como una opción terapéutica en pacientes con trastornos respiratorios del sueño, evidenciando la relación entre la modificación anatómica y la resolución de síntomas.

Abstract original

Objectives: This study aimed to evaluate the therapeutic effcacy of custom-made mandibular advancement devices (MAD) in the control of primary snoring and sleep apnea and to correlate with anatomical changes identified through imaging tests. Methods: Patients (n = 17) diagnosed with sleep apnea or primary snoring were included in this study and subsequently treated with MADs. Changes were assessed using a polysomnographic study (PSG), the Epworth Sleepiness Scale (ESS), and an imaging study with computed tomography scanning (CT). Studies were performed before and after the use of MAD. Anteroposterior measurements were taken in the sagittal plane at the hard palate, glottis, and supraglottic levels along the hard palate axis. Afterward, measurements were taken in the axial plane at the same levels along the hard palate axis. Results: From the six recorded measurements, the airway caliber increased by five. However, these changes were significant only in two measurements (sagittal hard palate and axial supraglottic). Snoring was controlled in 16 of the 17 subjects. From these sixteen, 12 subjects had a correct opening of the airway at the hard palate level. Moreover, daytime sleepiness decreased in all subjects. Discussion: Present results suggest that sagittal hard palate and axial supraglottic opening after use of MAD are mainly responsible for eliminating snoring and improve sleep apnea.
