Background
Negative pressure wound therapy (NPWT) for postsurgical incision treatment has demonstrated benefits. A prospective randomized study was developed including 32 patients who underwent bilateral breast reduction mammoplasty. Patients served as their own control and received NPWT to one breast and fixation strips to the other breast.
Methods
The primary outcome was the number of wound healing complications within 21 days when comparing NPWT treatment with fixation strips. The secondary outcome was aesthetic appearance and quality of scarring using questionnaires [visual analogue scale (VAS) and Patient and Observer Scar Assessment Scale (POSAS)] scored at day 42-, 90-, 180- and 365-day follow-up using additional scar measurement modalities, such as viscoelasticity.
Results
For the 32 included patients, the number of wound complications was significantly lower (p < 0.004) for the NPWT treated sites compared to fixation strips. POSAS and VAS scores at 42 and 90 days revealed a significantly better quality of scarring in the NPWT treatment breasts than in fixation strips. At 180-day follow-up, there was a significant improvement in VAS scores, as well as a comparable improvement in POSAS scores. No consistent significant improvement in scar quality was demonstrated with the assays that were used.
Conclusions
Our study showed less complications and a significant improvement in quality of scarring in favor of the NPWT-treated sites. The results indicate NPWT to be an attractive option for these patients.
