Abstract:

Objective    To evaluate the clinical value of a portable apneagragh in the preoperative assessment of  uvulopalatopharyngoplasty(UPPP). Methods    Twenty-one patients with obstructive sleep apnea-hypopnea syndrome(OSAHS) were subjected to  UPPP by the Friedman staging system. Two days before UPPP, all  underwent a portable apneagraph study in the ward. Results   1.The apneagraph provided detailed parameters about sleep-related breathing disorders and the level of upper airway obstruction. 2.Most of the patients had both upper and lower obstruction. Sixteen cases(76.19%) showed predominantly upper pharyngeal obstruction and five cases(23.81%) showed predominantly lower pharyngeal obstruction. 3.There was little correlation between the retropalatal obstruction localized by the apneagraph and the Friedman′s stages. Conclusion    The portable apneagraph can analyze sleep-related breathing disorders and identify the level of upper airway obstruction. It has great directive significance in selecting patients for UPPP.
