Abstract:
Objective To discuss the diagnostic value of high resolution computed tomography (HRCT)and MRI in the congenital inner ear malformation incomplete partition type Ⅱ deformity(Mondini deformity)combined with spontaneous cerebrospinal fluid (CSF)otorrhea.Methods The imaging data including the multiplanar reformation(MPR)images of HRCT,curved planar reforma-tion(CPR)images and MR hydrography images in three patients complicated with recurrent meningitis were retrospectively ana-lyzed.The anatomic changes of the inner ear and middle ear on the affected side were observed,the clinical and imaging features of this disease were summarized.Results One patient had bilateral incidence of the incompletely separated inner ear,combined with semicircular canal dysplasia and cochlear pipe dilation.Two patients had unilateral onset,one of them had concurrent facial nerve ca-nal dysplasia.Humble stapes floor and the defect of the bottom of the internal auditory canal were seen in all the three patients.Con-clusion HRCT with post-processing technology,and MRI have great significance in the diagnosis of the congenital inner ear malfor-mation incomplete partition type Ⅱ deformity (Mondini deformity)combined with spontaneous CSF otorrhea.
