FCT 1-4 : Factors predicting recurrence after surgical treatment of ear keloid

Background: Auricles are common sites of keloid formation. Auricular keloid can occur not only to localize in auricles but also be one among keloids presented in several anatomic sites. However, there was no formal study that describe clinical comparison of auricular keloids between with and without lesions of another anatomical sites. Objectives: To compare clinical features of auricular keloid between with and without lesions of another anatomic sites Methods: Total of 61 patients who were diagnosed as auricular keloid and treated by surgical procedures in our clinic, between 2009 and 2019 were retrospectively reviewed. They were divided into two patient groups; Auricle-localized group (n=30) and auricle-combined group (n=31, group combined to auricles and another anatomic sites). Results: The median onset age was 35.5 years old and Fifty-six patients (92.3%) were women. Auricle-localized group showed significantly younger onset age, lesser number of lesions, lesser familial association, and lower recurrence rate than auricle-combined group (p < 0.05). The overall recurrence rate was 7.8 percent. Their recurrence rates were significantly different (4.5 percent in auricle-localized group versus 14.4 percent in auricle-combined group; p < 0.05). Conclusion: This study revealed that auricle-localized keloid showed better prognosis than auricular keloid with lesions of another anatomic sites.
