This study showed the influence of the push-back operation on the occurrence of sleep-related apnea in cleft-palate patients with an analysis of arterial oxygen saturation (SpO2) during sleep, polygraphic analysis of nasal air flow, and chest wall movements. The postoperative SpO2 was lower than that of the presurgical period in all cases, requiring from five to nine days to recover to presurgical levels. According to polygraphic analysis this depression of SpO2 was caused by peripheral obstructive apnea, while, in spite of the cessation of nasal airflow, chest wall movement continued.
