【摘要】Background The most common obstruction sites for obstructive sleep apnea hypopnea syndrome (OSAHS) are the oropharynx and the glossopharyx.The diagnosis of glossopharyngeal airway obstruction is difficult.The study aimed to assess the effect of upper airway reconstructive surgery for OSAHS based on polysomnography (PSG) after nasopharyngeal tube insertion (NPT-PSG),and to evaluate the clinical value of NPT-PSG in localizing the obstructive sites.Methods Seventy-nine OSAHS patients diagnosed with PSG were included in the study.PSG was repeated with a nasopharyngeal tube in place (NPT-PSG).Results of the two PSGs were compared.A NPT-PSG apnea hypopnea index (AHI) greater than 15 times per hour was used as a threshold for glossopharyngeal surgery.The cause of glossopharyngeal airway obstruction was taken into consideration in planning glossopharyngeal surgery.Assessment of efficacy was followed-up.Results After NPT-PSG,patients' AHI significantly decreased and
