- Abstract
Assessing the severity of glossopharyngeal obstruction is important for the diagnosis and therapy of obstructive sleep apnea hypopnea syndrome (OSAHS). The polysomnography (PSG) with nasopharyngeal tube insertion (NPT-PSG) has shown good results in assessing glossopharyngeal obstruction. The objective of this study was to compare NPT-PSG with Friedman tongue position (FTP) classification which was also used to evaluate the glossopharyngeal obstruction. One hundred and five patients with OSAHS diagnosed by PSG were included in the study. All the patients were successfully examined by NPT-PSG. Based on the grade of FTP classification, 105 patients were divided into four groups. The differences of the general clinical data, PSG and NPT-PSG results were analyzed among the four groups. And the coincidence of diagnosing glossopharyngeal obstruction of two methods was calculated. There was no significant difference among the four groups in general clinical data and PSG results. However, NPT-PSG results were significantly different among the four groups. Following with the increasing FTP, apnea hypopnea index increased and lowest saturation of blood oxygen decreased. There were 38 patients with and other 38 patients without glossopharyngeal obstruction diagnosed by both methods. The coincidence of two methods was 72.4 %. NPT-PSG is an easy and effective method in assessing the severity of glossopharyngeal obstruction. The coincidence between the NPT-PSG and FTP classification is good. But in some special OSAHS patients such as glossoptosis, unsuccessful uvulopalatopharyngoplasty or suspicious pachyglossia, NPT-PSG is better than FTP classification.
