ABSTRACT
This study aimed to investigate the micro-anatomical morphology of ossicular chain in term fetus using micro-CT, in order to analyze the parameters of internal ossicular structure that may affect sound conduction.Four ossicular chains from two term fetuses were scanned by micro-CT. The related structural parameters of the trabeculae within the incus and malleus were calculated and compared. The fine anatomical structure of the auditory ossicles was analyzed.The microstructure of each auditory ossicles in term fetuses was clearly revealed by micro-CT. A marrow cavity was observed in the incus and malleus. In statistical analysis of the structural parameters of trabeculae in the incus and malleus, significant differences were found in BS/BV and Tb.Th (P < 0.05). Micro-CT enables the visualization of internal ossicular structure. The auditory ossicles in term fetus has good bone quality. The obtained bone structure data will help to clarify the physiological functions of normal fetal auditory ossicles.
RESUMEN
Este estudio tuvo como objetivo investigar la morfología microanatómica de la cadena osicular en el feto a término con micro-CT, con el fin de analizar los parámetros de la estructura osicular interna que pueden afectar la conducción del sonido. Cuatro cadenas osiculares de dos fetos a término fueron examinadas por micro-CT. Se calcularon y compararon los parámetros estructurales relacionados de las trabéculas dentro de los incus y malleus. Se analizó la estructura anatómica fina de los osículos. Se observó claramente la microestructura de cada osículo en los fetos y la cavidad medular en el incus y el malleus. En el análisis estadístico de los parámetros estructurales de las trabéculas en el incus y el malleus, se encontraron diferencias significativas en BS / BV y Tb.Th (P <0,05). Micro-CT permite la visualización de la estructura osicular interna. Los osículos en el feto a término tienen buena calidad ósea. Los datos obtenidos de la estructura ósea ayudarán para aclarar las funciones fisiológicas de los osículos auditivos fetales normales.
