Eyelid Tightening and Improved Eyelid Aperture through Nonablative Fractional Resurfacing

DERMATOLOGIC SURGERY, Issue 11 2008
SEAN A. SUKAL MD
BACKGROUND AND OBJECTIVE The effects of fractional resurfacing on eyelid tightening and aperture are unknown. Our purpose was to retrospectively examine the potential for eyelid tightening and eye-aperture opening in patients treated with nonablative fractional resurfacing for facial photorejuvenation. STUDY DESIGN/MATERIALS AND METHODS Fractional laser treatments using a 1,550-nm erbium-doped fiber laser system on the upper and lower eyelids were given at a pulse energy of 17 to 20 mJ at 125 micro-thermal zones (MTZ)/cm2 to a final density of 500 to 750 MTZ/cm2. Each patient had 3 to 7 treatments. Standard pre- and post-treatment photographs were taken at each visit. Physicians who graded 31 preselected patient photographs using a 4-point scale evaluated eyelid tightening. Increase in eyelid aperture was also evaluated. RESULTS All patients had some degree of eyelid tightening; 19% achieved 1% to 25% tightening, 26% achieved 25% to 50%, 26% achieved 50% to 75%, and 29% achieved 75% to 100%. Increase in eyelid aperture was seen in 55.9% of patients. Postoperative wounding, hypopigmentation, hyperpigmentation, persistent erythema, and scarring were not observed. All patients experienced mild or no edema for a few days after treatment. CONCLUSION Fractional resurfacing tightens and increases eyelid aperture without wounding, downtime, or long-term complications. [source]


3D virtual simulator for breast plastic surgery

Abstract We have proposed novel 3D virtual simulation software for breast plastic surgery. Our software comprises two processes: a 3D torso modeling and a virtual simulation of the surgery result. First, image-based modeling is performed in order to obtain a female subject's 3D torso data. Our image-based modeling method utilizes a template model, and this is deformed according to the patient's photographs. For the deformation, we applied procrustes analysis and radial basis functions (RBF). In order to enhance reality, the subject's photographs are mapped onto a mesh. Second, from the modeled subject data, we simulate the subject's virtual appearance after the plastic surgery by morphing the shape of the breasts. We solve the simulation problem by an example-based approach. The subject's virtual shape is obtained from the relations between the pair sets of feature points from previous patients' photographs obtained before and after the surgery.

Evaluation of the newly established acne severity classification among Japanese and Korean dermatologists

THE JOURNAL OF DERMATOLOGY, Issue 5 2008

ABSTRACT Recently, we established an acne severity classification that is based on scientific evidence. Our classification allows three different methods for grading, which include general impression of consulted dermatologist, photograph-based estimation by independent experts, and grading by lesion counting. In our classification, we proposed standard photographs for the estimation of general severity to adjust the basis of judgments. In this study, we evaluated the validity of our classification. We made questionnaires of acne severity using acne patients' photographs, which were selected from the collection of representative photographs of our classification. Participants answered these questionnaires before and after our presentations about our classification of acne severity. We identified the conformity rate with our consensus decision. The results revealed that average conformity rates were raised from 67.0% to 88.9% among Japanese dermatologists and from 68.0% to 79.8% among Korean ones. These data show the adequacy of both our grading system itself and its presentation. We believe our classification will be one of the most effective and reasonable grading systems to classify acne severity. [source]
