BACKGROUND: Palatoplasty is aimed to achieve normal speech, improve food intake, and ensure successful maxillary growth. However, the velopharyngeal function is harder to control than other functions. Therefore, many studies on the prognostic factor of @entity1739 have been conducted. This study aimed to evaluate the relationships between speech outcomes and multimodality based on intraoral and preoperative three-dimensional computerized tomographic (CT) findings. METHODS: Among 73 @entity1 with @entity2419 who underwent palatoplasty between April 2011 and August 2014 at Kyungpook National University Hospital (KNUH), 27 were retrospectively evaluated. The 27 cases were non-syndromic, for which successful speech evaluation was conducted by a single speech-language pathologist (Table  1). Successful speech evaluation was defined as performing the test three times in 6-month intervals. Three intraoral parameters were measured before and immediately after operation (Fig.  1). On axial- and coronal-view preoperative facial CT, 5 and 2 different parameters were analyzed, respectively (Figs.  2 and 3). Regression analysis (SPSS IBM 22.0) was used in the statistical analysis. RESULTS: Two-flap palatoplasty and Furlow's double opposing Z-plasty were performed in 15 and 12 @entity1 , respectively. The operation was performed 11 months after birth on average. @entity1 with a higher palatal arch and wider maxillary tuberosity distance showed @entity2422 (p  <  0.05; Table  2). CONCLUSIONS: The useful prognostic factors of velopharyngeal function after palatoplasty were palate width and height, rather than initial diagnosis, treatment method, or palate length. Therefore, a more active intervention is needed, such as orthopedic appliance, posterior pharyngeal wall augmentation, or early speech training.
