Resumen

Introducción: Los stents intraorales son dispositivos que se utilizan para minimizar los efectos adversos de la radioterapia en tumores de cabeza y cuello. Este estudio tuvo como objetivo reportar el uso del stent intraoral en dos casos de tumor de paladar, tratados con cirugía y radioterapia adyuvante. Informe de los casos: El primer caso se refiere a un hombre de 26 años con carcinoma mucoepidermoide; el segundo, es una mujer de 55 años con carcinoma adenoide quístico. Previo a la radioterapia, se fabricó un stent intraoral para ambos pacientes, compuesto por dos placas de acetato (superior/inferior) y, en la inferior, se realizó una meseta para degradar y estabilizar la lengua. Se utilizaron dos columnas de resina acrílica como topes oclusales de altura constante. El dispositivo se utilizó durante la tomografía computarizada de planificación y en todas las sesiones de tratamiento de radioterapia. Los planes se evaluaron para dosis medias, y se observaron dosis bajas en la mandíbula y las glándulas parótidas. Las lesiones de mucositis oral se limitaron a la región tumoral, con grados máximos 2 y 3, respectivamente, solo en las últimas 10 fracciones de radioterapia. Después de más de cinco años de seguimiento, ninguno de los pacientes fue diagnosticado de toxicidades crónicas asociadas a la radioterapia, como xerostomía u osteorradionecrosis. Conclusiones: Estos dispositivos resaltan la importancia de la planificación interdisciplinaria y contribuyen directamente a una mejor calidad de vida durante y después de la radioterapia en pacientes con tumores del paladar.
