We measured velopharyngeal competence during articulation in 382 children with cleft palate from 1992 to 2006 using the rhinomanometer MPR–3100 manufactured by Nihon Kohden Co., Ltd. with software program NI–301 designed by our department and Nihon Kohden. To determine the most suitable method, we compared the maximum nasal airflow leaking during articulation of "a", "ʃ" and "n" of two groups, which included 8 cases with pharyngeal flap construction and 12 cases without operation. The maximum airflow leaking from the nostril during articulation in the flap construction operation group was significantly greater than that in the group without operation. We considered that measurement of airflow leakage from the nostril during articulation might be a useful modality to assess the indication for pharyngeal flap construction surgery in children with velopharyngeal incompetence.
