High-Resolution Ultrasound Imaging to Demonstrate and Predict Efficacy of Carbon Dioxide Fractional Resurfacing Laser Treatment

BACKGROUND
Fractional resurfacing is a new laser treatment used mainly for treating photoaging and acne scars.


OBJECTIVE
To demonstrate the efficacy of carbon dioxide (CO2) fractional resurfacing laser treatment using high-resolution ultrasound imaging and to evaluate factors predictive of response to the treatment.


MATERIALS AND METHODS
A prospective observational study was undertaken from January 2007 to August 2009. Laser treatment was performed using a CO2 fractional resurfacing device. Patients were offered high-resolution ultrasound imaging to follow up their treatment. Dermal and subepidermal nonechogenic band (SENEB) thicknesses were measured.


RESULTS
Twenty-four consecutive patients were ...
