Proposal and content validation of an orofacial myofunctional assessment protocol for individuals with cleft lip and palate

To create and validate the content of an orofacial myofunctional assessment protocol for individuals with cleft lip and palate. The first version of an orofacial myofunctional assessment protocol for individuals with cleft lip and palate was created by two speech-language pathologists, who contemplated the structural and functional aspects of the stomatognathic system. This version was analyzed by other two speech-language pathologists experienced in cleft lip and palate assessment, who suggested changes that led to the second version of the protocol. Dynamic and static images necessary for performing the orofacial myofunctional examination were recorded from three individuals with cleft lip and palate, who represented three life stages: childhood, adolescence, and adulthood. Five examiners evaluated the images, applied the proposed protocol, and judged each item regarding its clarity to validate the content, from Content Validity Index. The assessment protocol was finalized with 13 items, ten related to structural aspects and three related to functional aspects, with their corresponding sub-items. The general agreement in the validation of its content was 100%, so that only one stage was required. A protocol to evaluate the orofacial myofunctional aspects of individuals with cleft lip and palate was created with 13 items, as well as their corresponding sub-items, and its content was validated.
