Abstract:
Objective:To inquiry the variety difference of upper airway caliber OSAHS sufferer and normal person in quiet respiration Method:Twenty OSAHS sufferer who were viewed by PSG and 16 normal adults who hadve no chief complaint of sleeping disease were selected.The curves of the subjects in a respiratory cycle were recorded by respiratory monitoring system in PSG,while the morphological changes in the harynx of all subjects were observed by fiberscope in a calm respiratory cycle,and then both of the two processes simultaneously were recorded on the same computer.According to the different stages of respiratory cycle by analyzing respiratory curve the video had been edited into pictures about the various anatomical areas in the upper airway,he cross section area and the dimension of palate and lingua and root of the tongue region upper irway wereas studied by the image tools in computer,and the changes of areas and dimensions at palate,and lingua and root of the tongue region upper airway were calculated.Result:It was found that there wasis a morphological change f the upper airway with the respiratory movement in the both groups.The upper airway caliber decrease with inspiration begin and reach the most narrowing at the end of inspiration,then upper airway caliber enlarges with the expiration begin and reach the most widening at the end of expiration.No matter the normal group or the OSAHS roup has the obvious changes in the palate and lingua region on the diameter,the cross section area and the dimension in respiration.The changes in the palate and lingua region on the diameter,the cross section area and the dimension of OSAHS group were greater than normal group.No matter OSAHS group or normal group on the diameter nd cross section area change in the palate was obviously more than the tongue area and the root of tongue area.The changes of OSAHS group on the dimension in the palate were greater than the tongue area and the root of tongue area.Conclusion:There are periodically changes of upper airway during respiration cycle in normal adults and SAHS patients.The effects of respiration on upper airway caliber of OSAHS patients are more obviously than normal adults.and the increasing effects in OSAHS patients is one of OSAHS etiology.
