To compare the effect of two different humpectomy techniques in the internal nasal valve (INV) angle in human anatomic specimens. Seven human anatomic specimens (14 heminoses) were included. A strip of subdorsal septal cartilage was removed and, in each nose, the right side of the middle roof lied intact over and was sutured to the septal cartilage (spare roof technique [SRT]), whereas in the left side the upper lateral cartilage was folded and sutured to the septal cartilage (component dorsal hump reduction [CDHR]). The INV angle was measured pre- and postoperatively. Mean age of the specimens was 69.86 (60-80) years. Five were female. CDHR resulted in a mean change of +1.71 ± 3.12° ( = 0.197), +0.62 ± 6.89° ( = 0.817) and +6.97 ± 6.84° ( = 0.036) after resection of 2, 4, and 6 mm of septal cartilage, respectively. SRT resulted in a mean change of +1.27 ± 2.37° ( = 0.207), +6.89 ± 1.19° ( < 0.001), and +12.55 ± 1.79° ( < 0.001) after resection of 2, 4, and 6 mm of septal cartilage, respectively. In SRT, the amount of septal cartilage resection presented a significant correlation with change in INV angle ( = 0.813, < 0.001). In this human anatomic study, SRT significantly increased INV angle.
比较两种不同的鼻中隔成形术技术对人尸体标本内鼻阀（INV）角度的影响。纳入 7 个人体解剖标本（14 个半鼻）。切除一条鼻中隔背侧软骨条，在每侧鼻腔中，右侧鼻中隔顶骨完整覆盖并缝合到鼻中隔软骨上（备用顶技术[SRT]），而左侧则将上外侧软骨折叠并缝合到鼻中隔软骨上（鼻中隔驼峰部分切除[CDHR]）。术前和术后测量 INV 角度。标本的平均年龄为 69.86 岁（60-80 岁）。5 名女性。CDHR 切除 2、4 和 6mm 鼻中隔软骨后，INV 角度分别平均改变+1.71±3.12°（ = 0.197）、+0.62±6.89°（ = 0.817）和+6.97±6.84°（ = 0.036）。SRT 切除 2、4 和 6mm 鼻中隔软骨后，INV 角度平均分别改变+1.27±2.37°（ = 0.207）、+6.89±1.19°（ < 0.001）和+12.55±1.79°（ < 0.001）。在 SRT 中，鼻中隔软骨切除量与 INV 角度的变化呈显著相关（ = 0.813， < 0.001）。在这项人体解剖研究中，SRT 显著增加了 INV 角度。
