Utility of a Continuous External Tissue Expander in Complex Pediatric Wound Reconstruction

BACKGROUND

Soft tissue reconstruction following traumatic injury can be devastating. Reconstructive treatment modalities can prove to be complex. DermaClose (Synovis Micro Companies Alliance, Inc) is a relatively novel wound closure device that has gained popularity for continuous external tissue expansion (CETE).

METHODS

A single-institution case series of 3 traumatic pediatric soft tissue injuries in which DermaClose was used for soft tissue reconstruction as an alternative to free tissue transfer was presented. A review of the literature to identify similar reported cases was also conducted.

RESULTS

The authors report their success with the use of this continuous external tissue expander in the management of pediatric soft tissue injuries. Open tibial fractures were sustained by 2 patients, and 1 patient suffered an avulsion injury to the scalp; sequential DermaClose application was successfully utilized to achieve wound closure in all cases.

CONCLUSIONS

The minimal amount of data currently available in the literature that document the use of this continuous external tissue expander in pediatric patients suggest that its safety and efficacy are inadequately investigated in this population. The cases included in this report suggest DermaClose may be an alternative to traditional methods for complex soft tissue closure in pediatric patients. For larger wounds, repeat applications with sequential closure should be expected and is described in an algorithm within this report.

Tissue expanders with a focus on extremity reconstruction

INTRODUCTION

Acute traumatic or surgical wounds that cannot be primarily closed often cause substantial morbidity and mortality. This often leads to increased costs from higher material expenses, more involved nursing care, and longer hospital stays. Advancements in soft tissue expansion has made it a popular alternative to facilitate early closure without the need for more complicated plastic surgical procedures.

AREAS COVERED

In this review, we briefly elaborate on the history and biomechanics of tissue expansion and provide comprehensive descriptions of traditional internal tissue expanders and a variety of contemporary external tissue expanders. We describe their uses, advantages, disadvantages, and clinical outcomes. The majority of articles reviewed include case series with level IV evidence. Outcome data was collected for studies after 1990 using PubMed database.

EXPERT COMMENTARY

An overall reduction in cost, time-to-wound closure, hospital length-of-stay, and infection rate may be expected with most tissue expanders. However, further studies comparing outcomes and cost-effectiveness of various expanders may be beneficial. Surgeons should be aware of the wide array of tissue expanders that are commercially available to individualize treatment based on thorough understanding of their advantages and disadvantages to optimize outcomes. We predict the use of external expanders to increase in the future and the need for more invasive procedures such as flaps to decrease.
