Patient experienced scar quality using the Patient Scar Assessment Scale (PSAS) total score of the POSAS.
Achtergrond van het onderzoek
Rationale: Microneedling shows promising results on improving scar characteristics and overall scar opinion in acne and burn scarring. Because of this it is interesting to study the effect of microneedling on surgical scarring. The impact of donor site scarring after DIEP flap breast reconstruction and the growing demand for minimally invasive scar treatments urge the need for a study for this specific indication.
Objective: To investigate the effect of microneedling on the patient overall opinion of the abdominal scar quality after a DIEP flap procedure comparing the treated part and the untreated part of the scar.
Study design: a controlled split scar trial.
Study population: 30 women who have undergone a DIEP flap breast reconstruction in Radboudumc, after prophylactic or curative breast surgery in the past 18 months, but at least 6 months ago. Women have self-reported scar symptoms such as pain, itching, color, stiffness, thickness and irregularity or wish overall improvement of the scar quality.
Intervention: The procedure consists of 3 microneedling sessions using an electric-powered pen, performed on one abdominal scar half. The interval of the sessions is 4 weeks. Settings will be adjusted to participants comfort and the clinical visible uniform pin-point bleeding.
Control: The other half of the scar remains untreated.
Main study parameters: Patient experienced scar quality using the Patient Scar Assessment Scale (PSAS) total score of the POSAS. Secondary parameters are: patient experienced scar quality, patient satisfaction, subjective assessment of scar quality, objective scar quality and experienced side effects.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The microneedling device is applied with a CE class I marked device and will be used within the intended use. The risk of the study design, intervention, study population and social impact are negligible. The benefits of microneedling may have a positive effect on the whole abdominal scar, since we offer to treat also the untreated part of the scar after the study. We do not expect that the microneedling procedure pose a risk or burden to patients.
