RESUMENSe realizó un estudio cefalométrico de la vía aérea superior en pacientes con secuela de labio y paladar hendido unilateral (SLPHU) sometidos a procedimientos de cirugía ortognática, con la finalidad de conocer si existen cambios en la morfología de la vía aérea pre- y postquirúrgicos. El diseño del estudio fue observacional descriptivo, abierto, comparativo, retrospectivo y transversal en una muestra de 28 pacientes con SLPHU, correspondiendo el 50% al género masculino y 50% al femenino. El rango de edad fue de 16 a 29 años con un promedio de 19.32 años. Las mediciones fueron realizadas en radiografías laterales de cráneo pre- y postquirúrgicas, con un total de 672 trazos cefalométricos. Los hallazgos encontrados en el presente estudio muestran que sí existen cambios en la vía aérea superior después de los procedimientos de movilización ósea con cirugía ortognática. Se observó una diferencia estadísticamente significativa (p<0.05) en tres de las variables medidas: faringe superior (p=0.001), dimensión faríngea ósea (p=.000) y profundidad nasofaríngea (p=.000).ABSTRACTA cephalometric analysis of the upper airway in patients with cleft lip and palate sequelae who underwent orthognathic surgery was performed. The study aims to determine if changes in upper airway morphology occur. Study design: A retrospective, descriptive, open, comparative, and cross-sectional study with a sample of 28 patients with unilateral cleft lip and palate sequelae (UCLPS) was performed. The study sample consisted of 50% male and 50% female patients whose ages ranged between 16 and 29 years of age and averaged 19.32 years. Measurements were made on preand post-surgical lateral headfilms. A total of 672 cephalometric measurements were made. The study's findings indicate that changes in the upper airway after bone mobilization techniques in orthognathic surgery do exist. Statistical significance was set at p<0.05 and was met on three of the assessed variables: upper pharynx (p=0.001), bony pharynx dimension (p=.000), and nasopharyngeal depth (p=.000).
