Abstract:
Objective:Acoustic pharyngealmetry technology is utilized to evaluate the change and clinical significance of obstructive sleep apnea-hypopnea syndrome (OSAHS) patients caused by non-upper airway structural factor and normal individuals′ PWF(pharyngeal wall floppiness).
Methods:Acoustic pharyngealmetry instrument of Ecconvision was utilized to examine 102 OSAHS patients and 50 normal individuals, separately recorded their volume of pharyngeal cavity in sit or supine position, calculated PWF in sit or supine position, and SPSS 12.0 of tware was used to analyze data.
Results:PWF was 0.14±0.09 in sit position and PWF was 0.21±0.10, (t=5.96, t=9.63, P<0.001)in supine position of OSAHS group, which were all significantly higher than those of control group. PWFs in supine position of OSAHS group and control group were evidently higher than PWF(t=-11.91, P<0.001; t=-2.32, P=0.025) in sit position. ΔPWF(PWF_supine-PWF_sit)was 0.063±0.054 in OSAHS group which was significantly greater than in control(F=41.173, P<0.01). PWF in sit position and supine position were all positively related with age(r=0.714, r=0.735, P<0.001)while irrelevant with BMI(P>0.05).
Conclusions:PWF can be utilized to be an index to reflect the physiological feature of upper airway. PWF can more precisely reflect upper airway collapsibility of OSAHS patients on the condition of PWF in supine position. Pharyngeal wall floppiness quantified as a high PWF index is a non-structure vital factor of OSAHS patients and plays a role of guiding us to make personal treatment plans for OSAHS patients.
