We reported three cases of Waardenburg's syndrome and discussed CT findings of the temporal bones. Two cases of these patients were mother and daughter. Case 1, a two-year-old girl, had lateral displacement of the medial canthi, a broad nasal root, hetero-chromic iridis, left ptosis, albinotic fundus, and bilateral congenital deafness. CT findings of the temporal bones showed enlarged vestibules, short lateral semicircular canal, and absent right posterior semicircular canal. The mother had congenital deafness, heterochromia iridis, and a white forelock and showed similar abnormal CT findings of the temporal bones. Case 2, a one-year-old boy, had lateral displacement of the medial canthi, a broad nasal root, partial heterochromia iridis, albinotic fundus, and bilateral congenital deafness. CT findings of the temporal bones showed enlarged vestibules and absence of semicircular canals except the right lateral semicircular canal. These cases were diagnosed as Waardenburg's syndrome on the basis of the characteristic features.

To analyze congenital sensorineural hearing loss combined with blepharophimosis-ptosis-epicanthus inversus syndrome (BPES). For the case of cochlear implantation to child with congenital sensorineural deafness combined BPES, accomplish routine examination and assessment, combining with literature to analyze the clinical diagnosis of this disease and its significance. Sensorineural hearing loss is a common congenital diseases with neonatal incidence of 1 per thousand - 3 per thousand, 50%-70% of deafness is associated with genetic factors, the incidence of congenital sensorineural hearing loss combined with eye disease is about 40%-60%, mainly reflected in ametropia and retinopathy. BPES's main clinical manifestations is blepharophimosis, ptosis, epicanthus inversus, and telecanthus. BPES is a rare autosomal dominant disease caused by FOXL 2 gene mutation, sometimes associated with retarded growth, delayed development, congenital heart disease, and microcephaly. Suffering from both sensorineural hearing loss and BPES is rare in reported literature. This case is diagnosed by clinical examination, without visual impairment. Facial nerve dysplasia has been found during the surgery. For congenital deafness patients with eye disease or other diseases, timely and correct diagnosis has important clinical significance, which can improve the diagnostic rate and make it coming true to early intervention, and then, effectively improve the quality of the patients. There are few literature reports, of patients with two kinds of genetic diseases. Our inference is that the cases are rare or the patients has visited different departments and ignored the other systems' signs. Therefore, in such doubtful cases, we should do the professional comprehensive examination in daily clinical work in order to avoid missed diagnosis or delayed treatment and intervention. By analyzing this case, the patient may also suffer from facial nerve dysplasia. Preoperatively viewing CT scan and operatively facial nerve monitor being used can avoid the occurrence of surgical complications.
