To evaluate the efficacy of 3D printed nasal vestibular support on the recovery of nasal ventilation function and nostril shape after nostril stenosis treatment. Thirty-eight patients with unilateral traumatic nasal vestibular stenosis were selected and treated with 3D printed nasal vestibular support after operation. Subjective evaluation indicators, objective nostril local morphological and structural parameters, and nasal airflow dynamics parameters by numerical simulation were used. To evaluate the nostril morphological and nasal functional recovery after treatment. The subjective nasal congestion and nostril symmetry satisfaction VAS scores of the patients after nasal vestibular support treatment were improved to varying degrees compared with those before surgery; The nostril morphological parameters showed that the Δlong-axis ratio and Δ short-axis ratio were significantly decreased after nasal vestibular support therapy （0.09±0.09 and 0.16±0.13） compared with those before surgery（0.21±0.20 and 0.28±0.21） respectively（<0.01）. And the cross-sectional area of the nasal valve on the stenotic side nasal cavity increased from（0.40±0.27） cm² before operation to （0.71±0.26） cm² after treatment（<0.01）; The nasal resistance on the stenosis side nasal cavity also decreased from （0.036±0.024） Pa·s/mL before operation to （0.022±0.008） Pa. s/mL after treatment（<0.01）, and the total nasal resistance was decreased from （0.033±0.02） Pas/mL before operation to （0.021±0.007）Pa. s/mL after treatment（<0.01） ; It also showed that NWE（nasal warming efficiency） and NHE（nasal humidification efficiency） on the stenotic side nasal cavity were significantly decreased after nasal vestibular support therapy（[95.92±2.8]% and [94.55±4.17]%） compared with those before surgery （[97.94±1.97 ]% and [96.19±2.94]%） respectively（<0.01）. The 3D printed nasal vestibular support for postoperative support treatment on patients with anterior nostril stenosis can reflect the advantages of personalized treatment and allow patients to obtain satisfactory results, and the use of individually designed 3D printed nasal vestibular support can make the shape of anterior nostrils and nasal cavity normal ventilation function recover well, its clinical application prospect is worth looking forward to.
评估3D打印鼻前庭支撑物对鼻孔狭窄治疗后鼻通气功能恢复及鼻孔形态的疗效。选取38例单侧外伤性鼻前庭狭窄患者，术后采用3D打印鼻前庭支撑物进行治疗。采用主观评估指标、客观鼻孔局部形态和结构参数以及数值模拟的鼻气流动力学参数，以评估治疗后鼻孔形态和鼻功能的恢复情况。鼻前庭支撑治疗后患者的主观鼻阻塞和鼻孔对称性满意度VAS评分较手术前均有不同程度提高；鼻孔形态参数显示，鼻前庭支撑治疗后长轴比增量（Δlong-axis ratio）和短轴比增量（Δ short-axis ratio）较手术前（分别为0.21±0.20和0.28±0.21）显著降低（分别为0.09±0.09和0.16±0.13）（<0.01）。狭窄侧鼻腔鼻瓣膜横截面积从术前的（0.40±0.27）cm²增加至治疗后的（0.71±0.26）cm²（<0.01）；狭窄侧鼻腔鼻阻力也从术前的（0.036±0.024）Pa·s/mL降至治疗后的（0.022±0.008）Pa·s/mL（<0.01），总鼻阻力从术前的（0.033±0.02）Pa·s/mL降至治疗后的（0.021±0.007）Pa·s/mL（<0.01）；还显示狭窄侧鼻腔的鼻温效率（NWE）和鼻湿化效率（NHE）在鼻前庭支撑治疗后较手术前（分别为[97.94±1.97 ]%和[96.19±2.94]%）显著降低（分别为[95.92±2.8]%和[94.55±4.17]%）（<0.01）。3D打印鼻前庭支撑物用于前鼻孔狭窄患者术后支撑治疗，能体现个性化治疗优势，使患者获得满意效果，使用个体化设计的3D打印鼻前庭支撑物可使前鼻孔形态及鼻腔正常通气功能恢复良好，其临床应用前景值得期待。
