Research On OSAHS Patients’ Blocking Plane And Analysis Of The Regular Of Tongue Falling By MRI Images

Objective:.Researching of the OSAHS blocking plane and tongue falling to provide a certain values in the diagnosis of OSAHS、choosing operation method and the operation time to improve the efficient of OSAHS patients with surgical treatment.Methods: 1,Case selection: 66 normal control group(30 + 10) years old, the experimental group(38 + 9) at the age of 24 OSAHS patients(without nasal obstruction, adenoidectomy and tonsil hypertrophy); 2, MRI: two groups of tongue measurement MRI sagittal position in the middle of the image after clearance after the soft palate and tongue clearance distance tongue back and its relation to the position of the soft palate; Identify OSAHS patients with tongue after falling parts(in the middle, or after paragraph section), and the block plane positioning(soft palate plane,tongue and soft palate- tongue plane); 3, PSG examination: subjects in experimental condition(AHI) and oxygen(SPO2) degree.Result:1.The control group: the airway after the soft palate larger than the airway after the tongue.The tongue contact with the soft palate.2.The airway after the soft palate and tongue in the group of OSAHS patients compared with the normal group,there is significant difference, have statistically significant.3.The correlation coefficient in the OSAHS patients about the airway after the soft palate and the tongue with the age was 0.025、0.162, by under 5% significance level, the P values were greater than the critical value, so the airway after the soft palate and tongue was not significant correlation in statistical sense with age.4.The correlation coefficient about the airway after the soft palate and tongue in the group of OSAHS patients with severity was-0.596、-0.626,under 5% significance level, the P value is greater than the critical value, so the airway after the soft palate and tongue was significant correlation in statistical sense with severity,and have negative correlation.The correlation coefficient about the airway after the soft palate and tongue in the group of OSAHS patients with The level of hypoxia was-0.501、-0.690,under 5% significance level, the P value is greater than the critical value, so the airway after the soft palate and tongue was significant correlation in statistical sense with The level of hypoxia,and have negative correlation.5.The experimental group:the middle after falling50.0%(12 cases), after a period of tongue 45.8%(11 cases), after a period of tongue4.2%(1 case); 6, the experimental group: the soft palate plane blocking 62.5%(15cases), tongue flat 4.2%(1 case), the soft palate and tongue flat 33.3%(8 cases).Conclusion:1.The regular about the tongue dropping:tongue drop from middle to the posterior,Simple tongue period after falling rare seen.2.The AHI and the hypoxia affected the tongue dropping.3.The soft palate plane block chance is higher than simple tongue blocking.4.The main cause of the soft palate plane block may be tongue falling in the middle or later period, not the soft palate itself, so solve the tongue in the middle, after- after a period of falling problem could be solved the soft palate plane blocking’s major targets.
