摘要
目的研究腭裂畸形程度与腭裂语音之间的关联性。方法选择102例行腭帆提肌重建术的非综合征型腭裂患者为研究对象,其中完全性腭裂56例(CCP组),不完全性腭裂46例(ICCP组)。在语音频谱仪上测定患者在手术前及术后发[i]音时共振峰F1、F2、F3的数值,并与30例正常对照组(C组)的测定结果进行比较。患者的术后复诊时间为3～6个月。结果①C组、ICCP组术前和CCP组术前的F1值无统计学差异(P>0.05),F2、F3值有统计学差异(P<0.05),C组高于ICCP组,ICCP组高于CCP组;②C组、ICCP组术后和CCP组术后的F1值无统计学差异(P>0.05),F2、F3值有统计学差异(P<0.05),C组高于ICCP组,ICCP组高于CCP组;③ICCP组和CCP组进行组内自身比较,术前、术后的F1值无统计学差异,术后F2、F3值均高于术前(P<0.05)。结论腭裂畸形程度对腭裂患者的语音有影响,畸形越严重,患者舌位后缩越明显,术后软腭上抬动度越差,语音状况越不理想。
Objective To investigate the relation between different extents of cleft malformation with the speech characteristics in patients with cleft palate. Methods The formant frequency of vowel [i] of 46 incomplete cleft palate patients aCCP group） and 56 complete cleft palate patients （CCP group） before and after cleft palate repair, as well as 30 normal people（C group）, were measured and analyzed on spectrogram. Results The comparison of F1 between C group and CCP, ICCP before surgery showed no difference. So did the comparison of F1 between C group and CCP, ICCP after surgery. The comparison of F2 between C group and CCP, ICCP before surgery showed significant difference. The value of the C group was the highest. The value of the ICCP was higher than that of CCP. So did the comparison of F2 between C group and CCP, ICCP after surgery. The comparison of F3 between C group and CCP, ICCP （including before and after surgery） was similar to the results of F2 between the three groups. The comparison of F1 between before and after surgery in ICCP group showed no difference. However, the same kind of comparison of F2 and F3 showed significant differences： Both the values after surgery were higher than those before surgery. The comparison of F1, F2 and F3 between before and after surgery in CCP group was similar to that in ICCP group. Condusion The extent of the cleft malformation is closely related to the status of the speech in patients with cleft palate. With the malformation more severe, the tongue will move backward more obviously, the elevation of the soft palate after cleft palate repair will be less active. Two ways are recommended for those patients with CCP： ①Early interceptive orthodontic treatment to reduce the extent of palate malformation; ②The hard palate repair can be performed prior to the soft palate repair. Patients with severe cleft lip and palate can have hard palate repaired while accepting the early cleft lip repair.
