The Study of Ear Keloids by Surgical Excision with Fillet Flap in a Single Institution

Background and Objectives Keloids are benign dermal fibrous growth and excessive collagen deposition that occur usually after trauma or surgery. In the treatment of keloids, the recurrence rate is relatively high after surgical excision. Fillet flap is known to be a good surgical method for keloid lesions. The purpose of this study is to find out manifestation and compare the results of ear keloids after the surgery by fillet flap.Subjects and Method We retrospectively evaluated 22 patients with ear keloids (n=31) who underwent core excision with fillet flap at the Department of Dermatology, Chosun University Hospital from May 2010 to June 2018.Results With the 22 of treated patients and 31 ear keloid lesions, the average size of keloid lesions was 0.75×1.05 cm2 . The frequencies of occurrence with respect to the location of keloids according to the anatomical structure of the ear were 12 lobule (38.7%), 17 helix (54.8%), 1 antihelical fold (3.2%), and 1 postauricle (3.2%), respectively. There were 14 lobular types (45.2%), 9 dumbbell types (29.0%), 5 button types (16.1%), and 3 wrap-around type (9.7%). Recurrence was found in 8 keloid lesions (25.8%) and 5 patients (22.7%) after the surgery. Earlobe lesions and dumbbell shaped recurred with the highest recurrence rate. Among the 5 patients who relapsed, 4 had family history of keloids.Conclusion The earlobe and dumbbell shaped types showed the highest recurrence rate and family history was also an important risk factor for recurrence. Also, surgical excision with fillet flap can be very effective and is a good way to treat ear keloids.

Minimally Invasive Auricoloplasty With an Anterior Approach: A 15-Year Experience

Background The otoplasty technique, independently conceived by Kaye and Lewis, is a simple and effective method for correcting prominent ears with an underdeveloped antihelical fold, but it is inappropriate for correcting ears with conchal hypertrophy. Objectives To describe an anterior approach to otoplasty that can correct prominent ears, even for those with conchal hypertrophy. Methods The 100 most recent otoplasty interventions to correct prominent ears were analyzed retrospectively. Indications, aesthetic results, complications and corrections were evaluated. Results The 100 patients who underwent otoplasty included 40 males and 60 females with a mean age of 18 years (range, 8–62 years). Sixty-five patients underwent correction of an underdeveloped antihelical fold, 30 underwent correction of conchal hypertrophy and 5 required resection of a conchal cartilage crescent. Intervention was bilateral in 96 patients and monolateral in 4 patients. Two patients required secondary corrections, including 1 requiring monolateral correction for a trauma after 10 days. No patient experienced hematomas or infections, despite the absence of antibiotic coverage. Conclusions This minimally invasive otoplasty technique is a simple, quick, and effective method, even in patients with conchal hypertrophy. Level of Evidence: 4
