客观化
目的：通过分析腭咽闭合功能和鼻腔开放程度，评价正颌外科手术对唇裂术后患者声鼻音的影响，并探讨其可能的改变原因。
设计/患者
29例唇裂术前(Pre)、术后45d(POST1)和术后9个月(POST2)患者分别于术前(Pre)、术后45天(POST1)和术后9个月(POST2)进行鼻咽功能测试。在19例患者中，还测量了最小的腭咽闭合面积(VP)和鼻横截面积(N)。
干预措施
Le Fort I截骨术上颌骨前移联合鼻骨、上颌骨、下颌骨或全部三个部位的手术。
主要结果衡量标准
纳萨兰斯，副总区，N区。
结果
我们观察到：(1)在阅读口语和鼻音句子时，POST1和POST2的平均鼻音较Pre显著增加(p<；0.05)；在POST2，Pre时鼻音正常的患者中有45%的患者出现高鼻音，而在Pre时鼻音低的患者中有57%不再表现出异常鼻音；(2)POST1的平均VP面积显著增加；2名交界性患者在POST2时VP闭合程度比Pre恶化；(3)POST2时平均N面积显著增加，73%的患者不再出现Pre时的低于正常区域。
结论
在长期的基础上，正颌外科手术改变了一些有裂隙的受试者的语音鼻音，可能是因为内鼻尺寸的增加。这也可能改善鼻腔呼吸的通畅性。
OBJECTIVE
To evaluate the impact of orthognathic surgery on acoustic nasalance of subjects with cleft and investigate the causes of possible changes by analyzing velopharyngeal function and nasal patency.
DESIGN/PATIENTS
Nasalance was measured in 29 subjects with operated cleft palate +/- lip before (PRE) and 45 days (POST1) and 9 months (POST2) after surgery, on average. In 19 of the patients, the minimum velopharyngeal (VP) and nasal cross-sectional (N) areas were also determined.
INTERVENTIONS
Le Fort I osteotomy with maxillary advancement in combination with procedures involving the nose, maxilla, mandible or all three.
MAIN OUTCOME MEASURES
Nasalance, VP area, N area.
RESULTS
We observed: (1) a significant (p < .05) increase in mean nasalance at POST1 and POST2, compared with PRE during the reading of oral sentences and nasal sentences; at POST2, high nasalance on the oral sentences was observed in 45% of the patients with normal nasalance at PRE, and 57% of patients with low nasalance on the nasal sentences at PRE no longer presented abnormal nasalance; (2) a significant increase in mean VP area at POST1; two borderline patients demonstrated deterioration of VP closure at POST2, compared with PRE; and (3) a significant increase in mean N area at POST2, with 73% of patients no longer presenting subnormal areas seen at PRE.
CONCLUSIONS
On a long-term basis, orthognathic surgery modifies speech nasalance of some subjects with cleft, perhaps because of an increase in internal nose size. This may also improve nasal patency for breathing.
