Study summary

This is a prospective, randomized pilot study of patients who will undergo either early or late incisional laser therapy after breast reduction surgery to alleviate scar burden at NYU Langone Medical Center. The purpose of this study is to see how well carbon dioxide (CO2) laser therapy works at preventing scar formation after surgery.CO2 laser therapy is currently being used by dermatologists and plastic surgeons to help with scarring after acne and to rejuvenate the face; its benefits are now being explored by medical professionals in dermatology and cosmetic surgery to prevent scarring after surgery.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients of all ethnic origins will be considered, although certain ethnic groups will be preferentially excluded more than others such as black and South Asian patients due to our exclusion criteria related to darker skin individuals (see below).
  • Patients undergoing bilateral breast reduction surgery

Exclusion criteria

Exclusion Criteria:

  • Males will be excluded from this study as male patients rarely undergo breast reduction surgery. When males do undergo breast reduction surgery for gynecomastia, it is often unilateral, and is performed with several techniques and incision types that are not typical employed during female breast reduction. Thus, for this study, only female patients will be considered (see below).
  • Any patient enrolled in this study who shows evidence of delayed wound healing, dehiscence, or post operative infection at the first post operative visit will be excluded
  • Patients with darker skin (Fitzpatrick IV and above), which is a well-known to laser therapy
  • Pregnant patients
  • Patients who have had prior breast surgery
  • Patients who have had prior chest/breast irradiation
  • Patients with the following diseases which interferes with wound healing: prior hypertrophic scarring/keloids, type I or type II Diabetes Mellitus, diseases/collagen vascular diseases
  • Patients who are active smokers
  • Patients using blood thinners that cannot be stopped
  • Patients who have used aspirin within a week of the procedure date
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Study arms

  • Experimental
    Early Laser Therapy

    a group which will receive laser therapy to one breast incision at the first post-operative visit

    Other: CO2 Laser Administration

  • Experimental
    Late Laser Therapy

    a group which will receive laser therapy to one breast incision 6 weeks after surgery

    Other: CO2 Laser Administration

Interventions

  • OtherCO2 Laser Administration

    The CO2 fractional laser system will be applied at a pulse energy setting of 50 millijoules and a density of 100 spots/cm2 on one of the breast incisions (either one week after surgery or six weeks after surgery, depending on the randomization group).

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 6, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
