The Convenient And Untrauma Positioning Study On The Upper Airway Constriction Of The Obstructive Sleep Apnea Hypopnea Syndrome

Objective: To investigate the effect of the clinical scale of the magnitude of the tongue and palatopharynx(PP).Then to acquire a convenient and untrauma way in positioning diagnosis and severity of the obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods:①Make clinical scale of the magnitude of the tongue and the palate to the group of the OSAHS and the normal control②Successive scanning of the upper airway (UA) at the states of the normal inspiration and under the Müller action on both normal controls and the OSAHS patients with multi-slice spiral computed tomography (MSCT). The scope of scanning was from the roof of nasopharynx to the level of hypohyal, bonding multiplate volume reconstruction(MPVR),using the image workstation to survey the cross section area(CSA), sagittal diameter, coronal diameter on the soft tissue thickness in the lateral pharyngealwall(LPW) and posterior wall of the pharynx, and the postzone of soft palate(SP), uvula palatine ,tongue and epiglottis.Also we survey the magnitude of the tougue , which includes the parameters of the longitude,the width,the area of the middle longitude section and the height of the dorsum of tongue in the body of the tongue.Then study the normal extent of each plate in normal controls,the compliance feature of UA in OSAHS patients,the upper airway constriction position in OSAHS patients,the relationship between the OSAHS and the body of tongue through the contrast of the parameters in normal controls and the OSAHS patients.③Through the analysis of the correlation between the simple constriction and the magnitude of the PP of the OSAHS, we investigate the relationship between the constriction of the PP and the severity of the OSAHS, and in advance investigate the applicable value of clinical scale of above consicriction.④Through the contrast of the parameters in normal controls and the OSAHS patients ,and the comparison between the gentle OSAHS patients and the severe OSAHS patient, it's applicable to find the value of clinical scale of the magnitude of the tongue for the application.Results:①In the normal control group , the low limit of the CSA of the four areas were:Postzone of soft palate 107.94mm2,postzone of uvula 134.20mm2 palatine,postzone of the tongue200.68mm2 ,postzone of epiglottis 232.21mm2 the CSA of the four surveyed areas in the upper air way was smaller than the normal controls at both the states of the normal inspiration and the Müller action (P<0.05)②The total compliance of the pharyngeal wall was justo major(P<0.05),and the lateral wall of the UA was justo major with significant variance, which was at the postzone of SP, uvula palatine and epiglottis; while to the postzone of the tongue , no significant variance was found.The compliance of the anterior wall of UA was justo major with significant variance (P<0.05),while there was no significant variance (P>0.05) in the posterior pharyngealwall of the UA. The mean of the surveying parameters of tongue in the normal control is smaller than each surveying index of the OSAHS patients (P<0.05).By comparing the measurements between the wild OSAHS patients and the severe OSAHS patients, it was invariably that the magnitude of the body of the tongue has a certain dependability and relationship to OSAHS's pathogenetic condition(P<0.05).③The AI in the group of OSAHS with constrict PP has navigate correlation with the CSA of constrict PP(P<0.05).forthermore ,it have correlation of the clinical scale with the severity of the OSAHS(P<0.05).④The mean of the surveying parameters of tongue in the normal control is smaller than each surveying index of the OSAHS patients (P<0.05).By comparing the measurements between the wild OSAHS patients and the severe OSAHS patients, it was invariably that the magnitude of the body of the tongue has a certain dependability and relationship to OSAHS's pathogenetic condition(P<0.05).Conclusion:To investigate the positioning diagnosis and severity of the OSAHS, the clinical scale of the PP and the magnitude of the tongue could be a convenient and untrauma way.
