| Abstract: | Objective: To analyze CT finding of congenital stenosis of external meatus.Materials and Methods:Axial and coronal high resolution CT (HRCT) were performed in 30 cases including 40 ears with condution deafness diagnosed by pure tone hearing test.Results:In 40 ears, there were 34 ears with bony stenosis, 6 ears with membranous stenosis, 26 ears with stenosis of tympnum and 19 ears with anterior position of facial canal as well as 29 ears associated with malformations of ossicles. Conclusion: CT could definitely show stenosis of external meatus and provide information for surgery. |
