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.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
