Objective:
To Study the clinical features of congenital microtia and atresia . To evaluate the methods and results of the same microtia surgery, ear canal and middle ear reconstruction.
Method:
Statistically analysis of the data of the hospitalization microtia 62 ears of 58 cases of patient in our department from January 2005 to October 2010 waw conducted. These patients with congenital ear malformations are associated with aural atresia, ossicular chain abnormalities, severe conduction Deafness. All patients received preoperative temporal bone CT examination and reconstruction, hearing examination. Operation was given in two phases, first operation aim to form a line of ear, ear canal reconstruction, ear reconstruction, the second one aim to line of ear skin graft, cranial angle of the ear reconstruction.

Result:
The auricle plus external auditory canal, middle ear reconstruction came out with a good shape of the ear and the ear canal in close proximity to the normal population. Most patients' hearing were improved after surgery.
Conclusion:
Surgeries of patients with congenital ear malformations and aural atresia should be carefully designed according to the three-dimensional reconstruction of multislice spiral CT reconstruction, which can provide information about surgery approach and middle ear abnormality. The whole ear shape and hearing ear after reconstruction are improved after the surgery.
