AB  - BACKGROUND: Protruding ears are the most common congenital ear deformity, with a 
      frequency of 13.5%. Since 1845 and the first works of Dieffenbach, over 170 
      classical surgical methods have been proposed to correct it. We introduced 
      laser-assisted cartilage reshaping (LACR) in 2004 as an alternative to invasive 
      surgical otoplasty. METHODS: Between January 2008 and June 2008, 24 patients 
      underwent LACR for treatment of bilateral ear protrusion. Fourteen adults and ten 
      children were treated (mean age = 16.0 years, range = 6-45 years). No anesthesia 
      was used. Both sides of the entire helix and the concha were irradiated using a 
      1540-nm laser connected to a 4-mm spot handpiece with integrated cooling. 
      Fluences varying from 70 up to 84 J/cm(2) were applied. Immediately after the 
      irradiation, silicone elastomer was inserted inside the helix to give it the 
      desired shape. After 3 minutes a solid mold was obtained. Patients were asked to 
      keep this mold in place at all times with a bandage wrapped around the head for 
      the first 3 weeks and then for an additional 3 weeks only during the night. A 
      non-steroidal anti-inflammatory drug (NSAID) was prescribed to the patients for 3 
      days. At 1, 30, 60, and 90 days after the procedure, ears were checked and 
      photographs were taken. Clinical follow-up at 1 year was obtained via direct 
      patient contact or over the telephone. RESULTS: The treatment was well tolerated. 
      No hematomas or skin necrosis occurred. Contact dermatitis was observed in four 
      children and two adults as a result of inappropriate mold design. These patients 
      stopped wearing the mold and the shape of their ear did not improve. For the 
      remaining 18 patients (6 children and 9 adults), the expected ear reshaping was 
      obtained (fluence was 84 J/cm(2)). For three other adults, incomplete reshaping 
      of the ears was observed and can be correlated to a lower fluence (70 J/cm(2)). 
      CONCLUSION: LACR, performed without any anesthesia, is a safe and less morbid 
      approach to surgical otoplasty.
