Prenatal transformations of the temporal bone

Abstract

Congenital malformations of the temporal bone (including anomalies of the external, middle, and internal ear) can cause severe diseases in children, for example, hearing loss and balance problems (Yiin R.S.Z. et al., 2011). L. Sennaroglu et al. (2002) proposed classifications of internal ear abnormalities that include complete labyrinthine aplasia, cochlear aplasia, common cavity, incomplete division of types I and II, auricle hypoplasia, semicircular canal anomalies, and enlarged vestibular labyrinth. These defects usually develop in the embryonic and early pre-fetal periods, therefore, clarification of the features of the embryogenesis of the temporal bone is an actual direction of morphological research. The aim of the study of the study is to clarify the peculiarities and chronological sequence of the sources of the rudiments and the dynamics of morphological transformations of the temporal bone in the prenatal period of human ontogenesis.
