Outline of Final Research Achievements

The purpose of presurgical nasoalveolar molding (PNAM) treatment using PNAM plate for the infants with unilateral and bilateral cleft lip and palate (CLP) is a feeding aid for them and obtaining favorable nasoalveolar morphology before primary lip repair. In this study, we analyzed the change of nasoalveolar morphology three-dimensionally and how the soft tissue morphology changed. The purpose was to clarify the effect of PNAM treatment.
Treatment with PNAM increased the length of the nasal column and reduced the cleft size in infant with CLP and they obtained the good nasoalveolar morphology. We indicate that PNAM treatment can correct them to a advantage morphology in primary surgery.

Academic Significance and Societal Importance of the Research Achievements

片側性および両側性唇顎口蓋裂患児（CLP）に対するPresurgical nasoalveolar molding plate（PNAM） を用いた術前顎矯正治療が口唇形成術において有利な形態を得ることが可能となることで、口唇裂口蓋裂患者において審美的に安定した形態を得ることが可能となった。このことは、口唇裂口蓋裂疾患に対し治療を受けられる患者本人、家族のQOLを向上させることにつながると考える。
