Correction to: Randomized Controlled Study Comparing Disposable Negative-Pressure Wound Therapy with Standard Care in Bilateral Breast Reduction Mammoplasty Evaluating Surgical Site Complications and Scar Quality.

The second to last sentence in the Results section of the Abstract should be corrected to, "At 180-days follow-up, there was a significant improvement in total VAS scores."

Randomized Controlled Study Comparing Disposable Negative-Pressure Wound Therapy with Standard Care in Bilateral Breast Reduction Mammoplasty Evaluating Surgical Site Complications and Scar Quality.

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 total 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. LEVEL OF EVIDENCE II: This journal requires that authors assign a level of evidence to each article.

Efficacy of custom-made pressure clips for ear keloid treatment after surgical excision.

BACKGROUND: Mechanical pressure is increasingly applied as a means to prevent or treat keloid scars. AIM: The aim of this study is to analyze the long-term efficacy of our custom-molded pressure-adjustable earclips to prevent keloid recurrence after surgical excision. METHODS: Using our custom-molded earclip, 88 patients who had undergone ear surgery for keloid scars were treated for 12 h a day for 6-18 months. The mean follow-up was 6.5 years. The primary outcome was the recurrence of keloids with patient satisfaction being the secondary outcome as assessed by Patient and Observer Scale (POSAS). RESULTS: Keloid scars did not recur in 70.5% of treated patients. The Fitzpatrick scale, which classifies human skin by type, was significantly different between the recurrence and nonrecurrence group. Differences in other patient characteristics were not found between both groups. All parameters mentioned in the POSAS patient scale drastically improved after therapy. There were no severe side effects observed after the therapy. CONCLUSION: Our pressure-adjustable earclip model is an effective tool in the prevention of ear keloid recurrence and is associated with high patient satisfaction. Its benefits should prompt further studies on its value as an adjuvant therapy to surgery in keloid treatment. LEVEL OF EVIDENCE: Level III on the Evidence Rating Scale for Therapeutic Studies.
