  • Title: [Studies on factors affecting velopharyngeal functions of cleft palate patients].
    Author: Huang W, Song YG, Fang Z.
    Journal: Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi; 2004 Jan; 18(1):37-9. PubMed ID: 14768086.
    Abstract:
    OBJECTIVE: To investigate the relationship between velopharyngeal functions and factors such as age at operation, cleft type, performing procedure. METHODS: FFT technique and velopharyngeal X-ray examination were used to evaluate the velopharyngeal functions of 82 patients. The relatively important factors affecting velopharyngeal functions were searched out through regression analyse and pearson correlation. RESULTS: A significant positive correlation was confirmed between AAO(age at operation) and A1/A2(velopharyngeal incompetence), P < 0.001. AAO also showed linear regression with A1/A2. Model was significant, P < 0.001. Quotation: A1/A2(velopharyngeal incompetence) = 0.005 852 x AAO + 0.961. CONCLUSION: AAO was an important affecting factor on velopharyngeal functions. The earlier the cleft is repaired, the more normal velopharyngeal functions will be obtained.
