Linea Vestibularis: Follow-up of a Normal Genital Structure
Keen observation and precise documentation have become increasingly important in the physical evaluation of a child who may have been sexually abused. The task of proper interpretation of these [See table in the PDF file] physical findings depends on the recognition of normal anatomy. Much work has been done to differentiate normal anatomic variants from physical changes resulting from injury.1-7 In a recent study, healthy female newborns were examined to establish the presence of a white midline streak in the posterior vestibule.8 In the initial phase of this study, 123 newborns were examined. A white linear structure in the mid-posterior vestibule, termed linea vestibularis (LV), was found in 10% (n = 13) of the group and a white spot in the mid-posterior vestibule, termed partial linea vestibularis (PLV), was found in 14% (n = 17) of the group.
