Studying on patient's nasal cycle of OSAHS with acoustic rhinometry / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To study the effect of OSAHS on adult nasal-cycle.@*METHOD@#The nasal cycle of 20 healthy adults, 18 patients of snoring and 22 patients of OSAHS were examined with acoustic rhinometry, which was performed every 30 minutes in 7 hours.@*RESULT@#The ratio of nasal cycle in healthy adults was (19/20, 95.0%), in snoring patients was (15/18, 83.0%), in patients of OSAHS was (15/22, 68.2%). The mean alteration amplitude of nasal cycle in healthy adults was significantly larger than that in patients with OSAHS (P < 0.05). The distribution of the healthy adults and patients with OSAHS between the typical cycle categories was significantly different (P < 0.05).@*CONCLUSION@#The characteristics of nasal-cycle in of OSAHS patients were different with healthy adults, which maybe owing to change of physical function of basal cavity.
