Trisomy 13 has multiple physical anomalies.The aural malformations are also various.To date, a review of the literature showed 18 reports of the histopathological changes affecting the temporal bone in patients with trisomy 13.In this report, histpathological findings of the temporal bone of a fetus with trisomy 13 are described.
The first case, 35 weeks male, had multiple malformations in the middle and inner ears.The inner earpresented Mondini type dysplasia.
The second case, 21 weeks female, had also Mondini type inner ear dysplasia.Disorders of two cases are regarded as viviparity eight weeks in embryology.Inner ear malformations of trisomy 13 is variouly from mild to severe, and it seems to be difficult to classify.
Radiological evaluation of malformed classification in trisomy 13 will become useful in the future.
