慢性鼻及鼻竇炎患者之鼻咽－帆咽界面

BACKGROUND: It is available to qualitatively and quantitatively study the nasopharygovelopharyngeal interface by computed-tomography 2D Multi-planar reformatting (MPR) rather than traditional mirror examination or indirect endoscope. This study elucidates the nasopharygo-velopharyngeal interface of patients with chronic rhinosinusitis.METHODS: 207 adult patients (127 men and 80 women) aged 48.5 ± 15.8 (average ± SD) were enrolled. They have received sinonasal computed tomography due to chronic rhinosinusitis. Bilateral total Lund-Mackay scoring (LMS) were 8.2 ± 6.2. The image data are transferred to a post-processing computer workstation that allows generation of 2D MPR. We generate the axial cut just at the nasopharygo-velopharyngeal interface. The area and midline anterior-posterior diameter are measured. The α value of all statistical analysis is .05.RESULTS: The interface area of men (48.1 ± 16.2 mm^2) is not different from that of women (49.2 ± 15.0 mm^2) (two-tailed t test, p = .6355), and is negatively correlated (r = -.211) and regressive (b = -5.316) with the bilateral total LMS. The interface midline anterior-posterior diameter of men (18.6 ± 4.6 mm) is not different from that of women (19.5 ± 4.0 mm)(two-tailed t test, p = . 1303), and is also negatively correlated (r = -.192) and regressive (b = -.138) with the bilateral total LMS. However, either the midline anterior-posterior diameter or area is not significantly correlated or regressive with women's bilateral total LMS.CONCLUSIONS: We performed a preliminary study to confirm the midline anteriorposterior diameter and area of the nasopharygo-velopharyngeal interface would decrease as the bilateral total LMS increases in men with chronic rhinosinusitis during tidal respiration on supine position. However, deficiency of normal control group is the limitation.
