Major pretibial degloving injuries are complex wounds, which can be challenging to treat. Despite recent advances in reconstructive options, most of these injuries still require a prolonged healing period and may result in amputation. Few reports have been published on the management of these complex traumatic injuries. In this article, we present a case of an octogenarian, frail patient with a major pretibial degloving injury. Treatment included serial surgical debridements in combination with negative pressure wound therapy aimed at salvaging the avulsed tissue. Subsequently, a fenestrated-type artificial dermis and negative pressure wound therapy were used as combined therapy so as to obtain adequate soft tissue coverage. The patient made an unremarkable recovery and was discharged on day 22 after injury. The wound healed by secondary intention without need for skin grafting.

Objective: The aim of this systematic review is to analyze the 30-day postoperative mortality in patients undergoing free flap reconstruction for head and neck cancer published in literature and to identify associated factors. Methods: The authors performed a literature search between January 1950 and February 2020 in PubMed, EMBASE, and Scopus, using a combination of Medical Subject Headings headings and text keywords related to head and neck cancer; microsurgery or free flap reconstruction; and 30-day mortality. Inclusion criteria were: original studies in English reporting on 30-day mortality after head and neck free flap reconstruction in adult population. Results: Thirty-one publications reported on a total of 13,447 patients who underwent head and neck free flap reconstruction. The published 30-day postoperative mortality ranged from 0% to 6.3%, with an average of 1.21%. A number of studies examined the association between mortality and body mass index, American Society of Anesthesiologists, and comorbidity score and age. One study found that underweight patients had significantly higher mortality. Two studies found no association between the American Society of Anesthesiologists score and 30-day postoperative mortality; however, 1 study reported significantly higher mortality with increased comorbidity score. Regarding association with age, 3 studies found significant higher mortality in older patients, while 5 studies found no difference. Conclusions: The average 30-day postoperative mortality in patients undergoing head and neck free flap reconstruction is 1.21% and is; therefore, not negligible. Careful patient selection and preoperative optimization are essential in order to reduce mortality in head neck free flap reconstruction.

Background Complications from prosthetic breast reconstruction are distressing for patients, and their management is challenging. For decades, negative-pressure wound therapy (NPWT) has been successfully used for the closure of complex wounds. This study analyzes the outcomes of NPWT use in the prevention and management of complications from prosthetic breast reconstruction. Method A systematic search of studies published until August 2020 was conducted using the PubMed/MEDLINE, EMBASE, and Ebscohost/CINAHL databases and using the following key words: “negative-pressure wound therapy,” “breast reconstruction,” and “prosthesis” (including breast implants and tissue expanders). Analyzed endpoints were outcomes of NPWT use in prosthetic breast reconstruction compared with conventional dressings. The methodological quality of included studies was assessed independently. Comparative studies were further meta-analyzed to obtain pooled odds ratios (ORs) describing the effectiveness of NPWT in prosthetic breast reconstruction. Results/Discussion Ten studies were included with a total of 787 patients (1230 breasts) undergoing prosthetic breast reconstruction with breast implants or tissue expanders. Three case-control studies focused on preventing breast wound complications. The meta-analysis of the 3 studies included 502 breasts receiving NPWT and 698 breasts receiving conventional wound care. The meta-analysis favored NPWT for less mastectomy flap necrosis (5.6% vs 14.3%; OR, 0.46; 95% confidence interval, 0.27 –0.77; P = 0.004; I 2 = 0%) and less overall wound complications (10.6% vs 21.1%; OR, 0.49; 95% confidence interval, 0.35–0.70; P < 0.00001; I 2 = 0%). In the management of nipple-areolar complex venous congestion, 1 case report demonstrated 85% rescue of nipple-areolar complex after using NPWT (−75 mm Hg) for a total of 12 days. In the management of periprosthetic infections, 2 case series used NPWT with instillation. It accelerated the treatment of infection and maintained the breast cavity for future reconstruction. Conventional NPWT also showed good salvage outcome in four studies. Conclusions Current evidence suggests that prophylactic use of NPWT in prosthetic breast reconstruction reduces the rate of overall wound complications and mastectomy flap necrosis. In the management of complications from prosthetic breast reconstructions, NPWT may be a promising option showing beneficial results. Additional high-quality trials are warranted to corroborate the findings of this systematic review.
