title: Children with nocturnal upper airway obstruction: postoperative orthodontic and respiratory improvement.
abstract: Twenty children, aged 4-9 years, underwent adeno/tonsillectomy because of unequivocal anamnestic nocturnal obstructive breathing. Preoperatively, apnea-hypopnea index was > 5 in 10 cases only, AI > 1 in 17. Nineteen children had signs of increased respiratory labour in movement recordings and inspiratory EMG-activity. Oxygen desaturation index was 0 in 7 children, and nadir SaO2 was > or = 90% in 10. Cephalometry and dentition study models initially revealed significant changes, chiefly lateral cross-bite (n = 11) and vertical growth direction of the mandible. Tonsillar size or duration of disease was not correlated with the severity of polysomnographic findings, nor were orthodontic variables. Symptoms disappeared promptly postoperatively. After one year, respiratory recordings were normalized or improved in the majority of children, and orthodontic variables normalized or improved in all children.
  
  
  CONCLUSIONS
  Oximetry and airflow recordings may be normal in children who benefit from treatment of anamnestic nocturnal obstruction. Craniofacial deformities are common and improve significantly with surgical treatment of the airway obstruction.
