ABSTRACT
BACKGROUND: Ablative fractional carbon dioxide laser is widely used for the treatment of various scars including burn injuries. We applied ablative fractional CO2 laser on the skin graft scar of faces. METHODS: Fourteen patients between 2010 and 2013 who underwent facial skin graft were included in this study. The ablative fractional CO2 laser was applied to 7 patients in the laser therapy group. It was initiated at 5th week after the skin graft. Clinical photographs were taken, and Patient Scar Assessment Score (PAS) was obtained during every visit from a patient at the outpatient clinic and 4 weeks after the last laser treatment. In the untreated control group, clinical photographs and PAS were taken at 5th and 21st weeks after the skin graft. Vancouver Scar Scale (VSS) and Observer Scar Assessment score (OAS) was rated by single independent plastic surgeon with the clinical photographs. RESULTS: In the laser therapy group, VSS, PAS, and OAS improved after fractional laser treatment. In the untreated group, VSS was also improved by the natural process of scar maturation. However, the laser treated group showed significant improvement compared with the untreated group. CONCLUSIONS: The ablative fractional CO2 laser can be a viable option for the treatment of skin graft scar. Further study with sufficient patients and long term follow-up is necessary for definite conclusions.

BACKGROUND: The zygoma is the most prominent portion of the face. Almost all simple zygomatic arch fractures are treated in a closed fashion with a Dingman elevator. However, the open approach should be considered for unstable zygomatic arch fractures. The coronal approach for a zygomatic arch fracture has complications. In this study, we introduce our method to reduce a special type of unstable zygomatic fracture. METHODS: We retrospectively reviewed zygomatic arch view and facial bone computed tomography scans of 424 patients who visited the Wonju Severance Christian Hospital from 2007 to 2010 with zygomaticomaxillary fractures, among whom 15 patients met the inclusion criteria. RESULTS: We used a Dingman elevator and K-wire simultaneously to manage this type of zygomatic arch fracture. Simple medial rotation force usually collapses the posterior fractured segment, and the fracture becomes unstable. Thus, the posterior fracture segment must be concurrently elevated with a Dingman elevator through Keen's approach with rotation force applied through the K-wire. All fractures were reduced without any instability using this method. CONCLUSION: We were able to reduce unstable and difficult zygomatic arch fractures without an open incision or any external fixation device.
