Free Latissimus Dorsi Myocutaneous Flap in a 6-Month-Old Child for Reconstruction of a Temporal Fossa Defect After Teratoma Resection.

Although free flap reconstruction has already gained widespread acceptance in pediatric patients, little is known about the outcome of free tissue transfer in head and neck reconstruction in pediatric patients. We present a case of a 6-month-old boy with a large volume deficit in the right temporal fossa after resection of a teratoma. This led to a large volume deficit with widely undermined skin margins. Therefore, we provided volume augmentation by microsurgical free latissimus dorsi myocutaneous flap transplantation. Intraoperative use of laser-assisted indocyanine green angiography indicated excellent flap perfusion. Postoperative magnetic resonance imaging showed adequate flap perfusion with no signs of flap necrosis. To our best knowledge, this case presents the youngest patient who underwent free flap transplantation in the head and neck region. Our case demonstrates that microvascular surgery can play an important role in particular cases in pediatric oncology, even in very young patients.

Negative pressure wound treatment with computer-controlled irrigation/instillation decreases bacterial load in contaminated wounds and facilitates wound closure.

Microbial wound contamination is known to be a hindrance to wound healing. Negative pressure wound therapy (NPWT) with or without irrigation is known to optimise conditions in problem wounds. The aim of this study was to investigate the influence of computer-controlled wound irrigation with NPWT on the bacterial load in contaminated wounds. A total of 267 patients were treated with NPWT with automated instillation because of problematic wounds using an antiseptic instillation solution. In 111 patients, a minimum of 4 operative procedures were necessary, and swabs were taken at least at the first and at the fourth operation in a standardised procedure. The number of different bacteria and the amount of bacteria were analysed during the course. In a subgroup of 51 patients, swabs were taken at all 4 operative procedures and analysed separately. In an overall analysis, the number of different bacteria and the amount of bacteria significantly decreased independent of wound localisation and diagnosis. NPWT with automated instillation demonstrates a positive influence in the reduction of bacterial load in problem wounds. Thus, it may help to optimise wound conditions before definite wound closure.
