The efficacy and safety of low-energy carbon dioxide fractional laser use in the treatment of early-stage pediatric hypertrophic scars: A prospective, randomized, split-scar study.

Background: Various laser therapies have been introduced in scar management. However, pain during treatment has limited the application of laser therapy in pediatrics.

Objectives: To evaluate whether the use of the low-energy mode of a carbon dioxide (CO ) laser improves hypertrophic scars in a pediatric population.

Evaluation of effectiveness of three-dimensional printed ear splint therapy following ear elevation surgery in microtia patients: A randomized controlled trial.

Aim: This study aimed to compare the effectiveness of a 3D-printed ear splint with that of a conventional thermoplastic ear splint after microtia reconstruction.

Methods: Patients who underwent ear elevation surgery with postauricular fascia coverage between October 2017 and October 2018 were included. They were randomly divided into the experimental group (3D-printed ear splint) and the control group (thermoplastic ear splint) and underwent routine postoperative rehabilitation and antiscar therapy.
