Popis:	The clinical effectiveness of the pharyngeal flap operation for cleft palate has been widely documented. For the success of this operation, the lateral velopharyngeal apertures must be closed by mesial movement of the lateral pharyngeal wall during phonation, but they must be large enough for normal nasal breathing.To determine the minimum size of the lateral velopharyngeal apertures needed for normal nasal breathing, we measured their size with small balls. Nasal airway resistance was determined by both active-anterior and active-posterior methods. It was assumed that the pharyngeal flap had raised the resistance and disturbed nasal breathing when the difference in resistance between the two measurements was large.The minimum size of the two lateral velopharyngeal apertures needed for normal nasal breathing was found to be 6-7mm.
