ABSTRACT

SUMMARY:

Craniofacial morphology is a risk factor for obstructive sleep apnea syndrome. The general aim of this study was to investigate the craniofacial shape differences in adults with and without obstructive sleep apnea syndrome, using geometric morphometric methods. A descriptive study conducted in 106 adult Turkish subjects, consisting of 50 patients with OSAS diagnosed by polysomnography and 56 non-OSAS controls. Three dimensional craniofacial scanning processes were performed on patient subjects on the same day as the PSG. Twelve standard craniofacial landmarks were collected from each subject's 3D craniofacial scan. Geometric morphometric analysis was used to compare the craniofacial shape differences between the OSAS and non-OSAS control groups. No statistically significant difference in terms of general shape in face shapes was found between the OSAS group and control group. However, local significance differences were found. There were significant differences between the groups in some of the interlandmark distances 11 % of the interlandmark distances were greater in OSAS patients, and 29 % were greater in controls. Greater measured distances in OSAS are concentrated in the nasal region. In the control group, the difference is not concentrated in a specific region. Given the relationship of craniofacial structural alterations and sleep disordered breathing, we hypothesized that inter-landmark distance measurements in the craniofacial anatomy of patients might be predictive of OSA.
RESUMEN
RESUMEN La morfología craneofacial es un factor de riesgo para el síndrome de apnea obstructiva del sueño. El objetivo general de este estudio fue investigar las diferencias de forma craneofacial en adultos con y sin síndrome de apnea obstructiva del sueño utilizando métodos morfométricos geométricos. Un estudio descriptivo realizado en 106 sujetos turcos adultos, de 50 pacientes con SAOS diagnosticados mediante polisomnografía y 56 controles no SAOS. El proceso de escaneo craneofacial tridimensional se realizó en pacientes sujetos el mismo día que el PSG. Se recogieron doce puntos de referencia craneofaciales estándar del escaneo craneofacial 3D de cada sujeto. Se usó el análisis morfométrico geométrico para comparar las diferencias de forma craneofacial entre los grupos de control SAOS y no SAOS. No se encontraron diferencias estadísticamente significativas en términos de forma general en las formas de la cara entre el grupo SAOS y el grupo control. Sin embargo, se encontraron diferencias de significación local. Hubo diferencias significativas entre los grupos en algunas de las distancias interlandmark el 11 % de las distancias interlandmark fueron mayores en los pacientes con SAOS y el 29 % en los controles. Las mayores distancias medidas en SAOS se concentran en la región nasal. En el grupo de control, la diferencia no se concentra en una región específica. Dada la relación de las alteraciones estructurales craneofaciales y la alteración de la respiración durante el sueño, planteamos la hipótesis de que las mediciones de distancias inter-hito en la anatomía craneofacial de los pacientes podrían ser predictivas de la SAOS.
