Evidence - Based Speech - Language Pathology and

Purpose: To present recent studies that used the ultrasound in the fields of Speech Language Pathology and Audiology, which evidence possibilities of the applicability of this technique in different subareas. Research strategy: A bibliographic research was carried out in the PubMed database, using the keywords “ultrasonic,” “speech,” “phonetics,” “Speech, Language and Hearing Sciences,” “voice,” “deglutition,” and “myofunctional therapy,” comprising some areas of Speech Language Pathology and Audiology Sciences. The keywords “ultrasound,” “ultrasonography,” “swallow,” “orofacial myofunctional therapy,” and “orofacial myology” were also used in the search. Selection criteria: Studies in humans from the past 5 years were selected. In the preselection, duplicated studies, articles not fully available, and those that did not present direct relation between ultrasound and Speech Language Pathology and Audiology Sciences were discarded. Data analysis: The data were analyzed descriptively and classified subareas of Speech Language Pathology and Audiology Sciences. The following items were considered: purposes, participants, procedures, and results. Results: We selected 12 articles for ultrasound versus speech/phonetics subarea, 5 for ultrasound versus voice, 1 for ultrasound versus muscles of mastication, and 10 for ultrasound versus swallow. Studies relating “ultrasound” and “Speech Language Pathology and Audiology Sciences” in the past 5 years were not found. Conclusion: Different studies on the use of ultrasound in Speech Language Pathology and Audiology Sciences were found. Each of them, according to its purpose, confirms new possibilities of the use of this instrument in the several subareas, aiming at a more accurate diagnosis and new evaluative and therapeutic possibilities.
