背景:梨形支撑区的骨折会对面部外观和鼻气道通畅产生不利影响。与文献中的美学问题相比,鼻气道功能受到的关注较少。这项回顾性研究对该区域的不同骨折类型进行了分类,并确定了它们对鼻气道功能的影响。
■分析了梨状支撑区骨折患者的三维计算机断层扫描图像,以确定确切的骨折模式。使用声学鼻测量法评估和比较不同骨折类型患者的鼻气道功能。鼻测压,鼻塞症状评价量表。
结果:总体而言,47名患者,其中Ⅰ型骨折16例(高位骨折线;Ⅰ组),16例II型骨折(中间骨折线;II组),III型骨折15例(低骨折线;III组),包括在研究中。平均最小横截面积(MCA),I组的总鼻吸气阻力(Tri)和总鼻呼气阻力(Tre)分别为0.51±0.06cm2,1.67±0.11kPaL-1s-1和1.66±0.12kPaL-1s-1;II组的1分别为0.48±0.07cm2,1.89±0.15kPaL-1s-1和1.88±0.14kPaL-1s-1,0.94和1.31±1.21kPaI组鼻塞症状评估(NOSE)量表评分,II,和III分别为7.188、9.813和13.27。
结论:因此,鼻气道阻塞的严重程度取决于梨形支撑区骨折患者骨折骨的移位。最严重的鼻塞发生在骨折线最低的患者中。
BACKGROUND: Fractures in the pyriform buttress area adversely affect facial appearance and nasal airway patency. Nasal airway function has received less attention than aesthetic problems in the literature. This retrospective study classified the different fracture types in this area and determined their impact on nasal airway function.
UNASSIGNED: Three-dimensional computed tomography images of patients with fractures in the pyriform buttress area were analyzed to identify the exact fracture pattern. The nasal airway functions were evaluated and compared between patients with different fracture patterns using acoustic rhinometry, rhinomanometry, and the nasal obstruction symptom evaluation scale.
RESULTS: Overall, 47 patients, including 16 with type I fractures (high fracture line; group I), 16 with type II fractures (intermediate fracture line; group II), and 15 with type III fractures (low fracture line; group III), were included in the study. The mean minimal cross-sectional area (MCA), total nasal inspiratory resistance (Tri) and total nasal expiratory resistance (Tre) of group I were 0.51 ± 0.06 cm2, 1.67 ± 0.11 kPa L-1 s-1, and 1.66 ± 0.12 kPa L-1 s-1, respectively; those of group II were 0.48 ± 0.07 cm2, 1.89 ± 0.15 kPa L-1 s-1, and 1.88 ± 0.14 kPa L-1 s-1, respectively; and those of group III were 0.36 ± 0.04 cm2, 1.94 ± 0.21 kPa L-1 s-1, and 2.01 ± 0.34 kPa L-1 s-1, respectively. The nasal obstruction symptom evaluation (NOSE) scale scores for groups I, II, and III were 7.188, 9.813, and 13.27, respectively.
CONCLUSIONS: Therefore, the severity of the nasal airway obstruction depends on the displacement of the fractured bones in patients with fractures in the pyriform buttress area. The most profound nasal obstruction occurs in patients with the lowest fracture line.
