Current Practice in Assessing and Reporting Speech Outcomes of Cleft Palate and Velopharyngeal Surgery: A Survey of Cleft Palate/Craniofacial Professionals.
Conclusion: This survey shows considerable variability in the methods for evaluating and reporting speech outcomes following surgery. There is inconsistency in what is considered a successful surgical outcome, making comparison studies impossible. Most respondents thought that success should be defined as normal speech, but this is not happening in current practice.
