目的 评估上颌骨Le Fort I型截骨手术对鼻腔通气功能的影响.方法 采用NOSE量表对100例需要接受正颌手术治疗的患者行术前及术后6个月的鼻腔通气情况的主观性评估.结果 术前及术后6个月的NOSE量表评估数据差异有统计学意义(10.60±17.1 vs 6.2±10.9,t=3.766,P=0.001).结论 上颌骨Le Fort I型截骨术对患者鼻腔通气方面的生活质量无不良影响,部分原有鼻炎患者鼻塞症状得到了改善.“,”Objective To evaluate nasal airway function before and after Le Fort I osteotomy using a quality of life questionnaire. Methods The NOSE scale was used to evaluate nasal airway function preoperatively and at 6 months postoperatively in 100 patients who had undergone Le Fort I osteotomy. Results The mean score on the NOSE scale was 10.60±17.1 preoperatively and 6.2±10.9 at postoperative 6 months (t=3.766,P=0.001). Conclusion Nasal airway function was not affected by Le Fort I osteotomy. Pa-tients who had nasal congestion before surgery showed improvement in their nasal airway function after surgery.
