Surgery and follow-up care for auricular keloid: a report of 156 cases

Abstract Objective To treat and prevent auricular keloid so as to imporve the cure rate and lower the rate of recurrence. 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 subsequent 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 effective and they provided systematic and effective treatment for auricular keloid.

Hyperbaric oxygen therapy for skin flap blood flow disorder: a case report

Abstract A female patient at the age of 17 received dilator implant on the right part of her face to prepare skin flap for her facial scar. The skin flap was in good conditions before scar cutting, but showed poor blood circulation after being transferred. Hyperbaric oxygen therapy was given at 0.2 MPa (2ATA) in double pure oxygen cabins for 90 min every day for 10 d. The skin flap showed in sound viability and sound blood circulation after the treatment. Hyperbaric oxygen therapy can be used to treat blood circulation disorder in transferred skin flap.
