Abstract:
Objective To investigate the morphology characters of upper airway and its surrounding tissues in different age non-snoring males.Methods Total of 114 non-snoring males,with age-nlnge from 22 to 78 year old,were included in this study.They were divided into 3 groups:30 in younger group (22-29 years old),57 in middle-aged group(36-57 years old),and 31 in aged group(70-78 years old).All subjects had magnetic resonance imping sanning.Results (1)The nasopharynx in aged group was statistically different from that of the younger group and the midge aged group.The volume of nasopharynx in aged group(7.81±1.59)cm3 (χ-±s,same hereinafter) is greater than that in younger group(4.89±1.20)cm3 and middle aged groups(6.06±2.07)cm3.(2)The AP diameter/transverse dimeter of velophatynx,glossopharynx and laryngopharynx in the aged group tended to be smaller.The average value of AP diameter/transverse diameter of velopharynx in aged group is 0.46±0.14.while the value is 0.59±0.14 and 0.57±0.14 in midge and young groups respectively,compared with that of the aged group,there is statistical diffrence(P＜0.01).Further more,the min/max Section area of velophatynx,glossopharynx,hryngopharynx in aged group are smaller than that of young group and midlife groups.(3)The aged group had the thinnest thickness of posterior and lateral velopharyngeal walls,but the largest volume of soft palate and fatpads among all groups.Conclusions In non-snoring males,there is more fat deposition around the upper airway with aging.While the large naxopharynx and large transvdrse diameter of upper airway seem to balance the disadvantaged changes and to benefit the their sleep respiration.
