Diagnostic analysis of blocking position of the obstructive sleep apnea hypopnea syndrome

Zhang Wenbin;Department of Otolaryngology,the People's Hospital of Qingyang City;  
Objective:To investigate the difference of pharyngeal and lingual region may cause obstruction in the patients with obstructive sleep apnea hypopnea syndrome(OSAHS).Methods:46 cases with OSAHS were randomly selected in the hospital.We used the fiber laryngoscope combined with M agreement ller examination(FPMM) and night of upper airway pressure measurements(UAPM) methods to judge on the obstruction is pharyngeal or lingual region.The cases who used the method of UAPM by blocking ratio30% as a judge blocked standard.Results:In the cases who used the method of UAPM,36 cases were pharyngeal obstruction(72%),31 cases were obstruction of the lingual region(58%).In the cases who used the method of FPMM,respectively by the collapse degree≥75%,collapse degree≥90%.Two different numerical range as the judging standard pharyngeal obstruction.The number of pharyngeal obstruction detection rate and consistency coefficient increases with increasing the degree of collapse,respectively by the collapse degree≥75%,collapse degree≥50% for the determination of the lingual region blocking standard.The number of occlusion detection rate and consistency coefficient decreased with increasing the degree of collapse.Conclusion:On the palate and lingua region are determined by FPMM and UAPM these two kinds of methods.Consistency pharyngeal obstruction is higher than the lingual region.For the consistency that FPMM and UAPM of the two methods,it can improve FPMM determine the pharyngeal obstruction and reduce its judgment standard of lingual region blocking criteria.
