Acoustic analysis of cry in with cleft palate patients.
2020
espanolIntroduccion: El llanto de los recien nacidos y lactantes es una expresion funcional de interes biologico, por lo cual, a traves del analisis acustico del llanto se pueden evaluar los resultados de una palatoplastia primaria en pacientes con hendidura palatina antes del desarrollo del habla, por ser una herramienta objetiva, no invasiva, rapida y sencilla de exploracion vocal. El objetivo es determinar la frecuencia fundamental (F0) del llanto espontaneo en los pacientes con hendidura palatina pre y posoperatorio, y comparar con el grupo control sano a traves del software PRAAT, en el periodo entre el ano 2017 y 2019. Materiales y metodos: Se obtuvo una muestra de 16 pacientes de 18 a 30 meses de edad con hendidura palatina. Se realizaron grabaciones del llanto espontaneo pre y posoperatorio, y del grupo control sano; posteriormente fueron grabadas digitalmente, y analizadas a traves del software PRAAT. Resultados: El 56,2 % fue del genero femenino y el 43,7 % del genero masculino, con edad promedio de 25,8 meses. Se realizo palatoplastia primaria mediante tecnica de Veau Wadrill y tecnica Furlow. La F0 del llanto fue de valor promedio Pitch 349.125 Hz preoperatorio y un control posoperatorio promedio Pitch 369.775 Hz. Se evidencio emisiones del llanto mas agudas en el posoperatorio (p Conclusion: Se determino frecuencia fundamental (F0) en los pacientes con hendidura palatina, presentaron un incremento significativo de 15,5 % en los controles posoperatorio de palatoplastia primaria, similares al grupo control sano. EnglishIntroduction: Crying in newborns and infants is a functional expression of biological interest. Through, acoustic analysis of crying, results of a primary palatoplasty can be evaluated in patients with cleft palate before development of speech, is objective, non-invasive, quick and simple tool for vocal exploration. The objective is to determine Fundamental Frequency (F0) of spontaneous crying in patients with pre and postoperative cleft palate, and compare with healthy control group through PRAAT software, in period between 2017 and 2019. Materials and methods: A sample of 16 patients from 18 to 30 months of age with cleft palate was obtained. Recordings were made of spontaneous pre and postoperative crying, and healthy control group; later were digitally recorded, and analyzed through PRAAT Software. Results: 56.2 % were female and 43.7 % were male, witn average age of 25.8 months. Primary palatoplasty was performed using Veau Wadrill technique and Furlow technique. F0 of crying was Pitch average value 349.125 Hz preoperative and Pitch average postoperative control 369.775 Hz. More acute crying emissions were observed in postoperative period (p Conclusion: Fundamental frequency (F0) was determined in patients with cleft palate, they presented a significant increase of 15,5 % in postoperative controls of primary palatoplasty, similar to healthy control group.
