Abstract
Objective;To evaluate the diagnostic value of 320 - detector row 640 - slice dynamic volume CT for ear malformation. Methods: Forty -four ears in 31 patients with congenital ear lesions were examined with Toshiba Aquilion One 320 - detector row 640 - slice dynamic volume CT system (160 ×0. 5 volume scanning mode) from January 2011 to January 2012. The conventional 1.0— mm cross - section reconstruction was performed with high — resolution algorithm (sharp verysharp or bone) based on the collected data. Results:In 16 patients, external auditory canal atresia was found in 18 ears, tympanic cavity paramorphia in 4 ears, auditory ossicle paramorphia in 3 ears,both tympanic cavity and auditory ossicle paramorphia in 1 ear,and diploetic type mastoid in 2 patients. Five ears had external auditory canal stenosis in 4 patients. Ninteen ears had paramorphia or malformation of inner ear in 10 patients. Conclusion;The 320 -detector row 640 -slice dynamic volume CT scanner is an advanced and reliable diagnostic tool for ear malformation.关键词
