En los niños, la hipertrofia adenoamigdalar (HAA) puede producir trastornos respiratorios durante el sueño. El tratamiento de elección es la amigdaloadenoidectomía (AAT), cuya eficacia se debe valorar dependiendo de la mejoría de la clínica y de los patrones polisomnográficos.

Hemos estudiado a 11 niños (7 niños y 4 niñas; edad media = 5,5 años) con HAA sintomática corregida mediante AAT. Se realizaron 2 estudios polisomnográficos nocturnos (SleepLab): uno basal y un control 6 meses después de la AAT. Se analizaron los registros polisomnográficos cuantificando: a) sólo las apneas e hipopneas de duración ≥ 10 s, y b) todos los eventos respiratorios de ≥ 5 s.

Los síntomas más frecuentes fueron el ronquido, la disnea nocturna y las apneas del sueño. Después de la AAT se resolvió el cuadro clínico en la mayoría de los casos. Tras la cirugía disminuyeron todos los eventos obstructivos, sobre todo las apneas de menor duración (≥ 5 s) y las hipopneas. No se encontraron cambios en la SaO2 basal, pero sí mejoró la SaO2 mínima y disminuyó el número de saturaciones, sobre todo las derivadas de las alteraciones respiratorias.

Adenotonsillar enlargement (ATE) can cause respiratory disorders during sleep in children. The treatment of choice for ATE is adenotonsillectomy and its efficacy must be assessed based on improvement in symptoms and polysomnographic patterns.

We studied 11 children (7 boys and 4 girls, age 5.5 years) whose ATE symptoms were corrected by adenotonsillectomy. Two nighttime polysomnograms (SleepLab) were recorded, one at baseline and one 6 months after adenotonsillectomy. Polysomnographic recordings were analyzed by quantifying 1) only apneic or hypopneic events lasting ≥ 10 sec and 2) all respiratory events ≥ 5 sec.

The most common symptoms were snoring, nocturnal dyspnea and sleep apnea. Symptoms resolved after adenotonsillectomy for most patients. Obstructive events, in particular shorter apneic events (≥ 5 sec) and instances of hypopnea, decreased after surgery. We found no changes in baseline SaO2, although the minimum SaO2 improved and the number of desaturations decreased, above all those stemming from respiratory events.
