Methods:Taking 156 sufferers of auriclar keloid at the orthopaedics department of the Southwest Hospital under the Third Military Medical University from June, 2008 to June, 2011 as the research subject, this research carried out retrospective analysis and summary of different surgical methods with the clinical data of subseque nt treatments, including medicament, radiotheropy, pressure, etc. Results:There was no auricular cartilage necrosis and deformation in the total of 156 cases. It was found that 134 cases were cured in a year of postoperative follow-up, getting the care rate to 85.9%. The treatment was effective on 20 cases, with the effective rate of 12.8%, while it was ineffective on 2 cases, with the ineffective rate being 1.3%. However, two cases showed tendency towards recurrence, which were treated effectively by non-surgical methods like local hormone injection. There was neither recurrence nor apparent hyperplasia of hypertrophic scars on the rest cases, with the auricle and the earlobe in good shape. Conclusion:By auricular keloid excision and stripping surgery, surgical suture tension was reduced. Glucocorticoid and radiotherapy were instantly applied to inhibit pyperplasia of cicatrical tissue. Subsequently, pressure, anti-scarring drugs and silicone membrane were adopted to ensure fine postoperative apperance and reduce recurrence. These methods were proved to be effectiveand they provided systematic and effective treatment for auricular keloid.展开更多
