Dermal skin template for the management of multiple cutaneous leiomyomas

Dermal Matrices: Game Changers in Leg and Foot Soft Tissue Reconstruction? A Case Series

The present article aims to present the use of dermal matrices in severe degloving, avulsion, and necrotizing injuries of the leg and foot in 3 patients. Conventional reconstruction would require the use of free flaps, since exposure of vessels, nerves, joints, and tendons rendered the mere resurfacing with skin grafts insufficient, and extensive cutaneous detachment precluded the use of local fasciocutaneous flaps. All injuries underwent thorough and repeated surgical debridements and wash outs, followed by negative pressure wound therapy (NPWT). Once negative tissue cultures were obtained, the extremities were resurfaced with dermal matrix and immediately covered by split thickness skin grafts. NPWT on the grafted area for a week effectively secured the grafts on the recipient area. Complete healing was achieved in all grafted areas within 7 to 12 days. The function of joints and tendons as well as the quality of resurfacing at the weight bearing areas were tested and found satisfactory within a follow-up period of 5 to 15 months. The use of combined NPWT and dermal matrices in carefully selected patients provides a reliable and durable reconstructive option for leg and foot injuries with satisfactory functional outcomes.

Skin cancers and dermal substitutes: Is it safe? Review of the literature and presentation of a 2-stage surgical protocol for the treatment of non-melanoma skin cancers of the head in fragile patients

Non-melanoma skin cancers (NMSC) represent the most common skin tumours of the head region. We describe the use of dermal substitute in a 2-stage surgery protocol for selected fragile patients to remove NMSC of the head region. A review of the literature focusing on dermal substitutes' safety after skin tumours excision is provided. A total of 45 fragile patients with NMSC in the head region were selected and scheduled for the 2-stage surgical protocol. The first stage consisted of traditional surgical excision and immediate coverage with Hyalomatrix (Fidia Advanced Biopolymers, Abano Terme, Italy). After histology confirmed diagnosis and clearance of the margins, full-thickness skin autografts were performed. All of the patients reached complete tumour excision and wound healing. No local recurrences were registered during 24 months follow up. The 2-stage surgical therapeutic-diagnostic-reconstructive approach represents a less stressful and oncologically safe surgical protocol in selected fragile patients. When patients cannot tolerate invasive and long surgical procedures, general anaesthesia, and long hospitalisation, skin grafting following temporary skin substitute coverage can achieve oncological clearance and provide good functional and aesthetic results. The use of dermal substitutes represents a valid alternative surgical option in cases of ASA III, fragile patients non-eligible for complex reconstructive surgery. To our knowledge, this is the first paper reviewing literature focusing on dermal substitutes' applications and safety after skin tumour excision.

Dermal Matrix for Intraoral Lining Following Composite Mandibular Defect Reconstruction With Chimeric Fibular Osseocutaneous Flap

BACKGROUND

This report aims to first present Integra as an adjunct to complex mandibular reconstruction for intraoral lining resurfacing, and to review the literature on the use of dermal matrices for mucosal resurfacing of the floor of the mouth.

CLINICAL REPORT

A 62-year-old female patient with previous ablation surgery for squamous cell carcinoma of the floor of the mouth, presented with extrusion of the mandibular plate through the chin skin and serious tongue tethering. The patient was managed with a chimeric osseocutaneous free fibula flap to restore the mandibular bone and chin skin defect, followed by a second-stage reconstruction of the intraoral defect with bilayer Integra. Complete release of tongue tethering was achieved enabling normal speech and deglutition and allowing for dental rehabilitation.

CONCLUSIONS

Integra was safely used as an alternative for intraoral lining, in composite mandibular reconstruction, downgrading reconstructive demands and offering optimal functional results.

Natural expansion of artificial dermal template by successful full-term pregnancy

Extensive postburn scars of the trunk may cause breathing difficulty and, in female patients of reproductive age, render future pregnancy a serious reconstructive goal. Scar excision and skin grafting with or without artificial dermal templates is the current preferred management. A patient who underwent staged extensive grafting of the abdominal wall by dermal regeneration template and completed a full-term successful pregnancy is presented here. Although tissue expanders have been used to expand artificial dermal templates, natural expansion by pregnancy has not been previously documented. A 30-year-old woman with extensive chest and abdominal wall, bilateral gluteal and breast scars after burns sustained at childhood presented with difficulty in deep breathing. Abdominal scar tissue was excised and the abdominal wall was reconstructed by dermal regeneration template and autologous thin split-thickness skin graft in two stages. Six months postoperatively, spirometric values were improved by 15%, while 1 year later the patient completed successfully a full-term pregnancy. Reconstruction of extensive abdominal postburn scars by dermal regeneration template improves breathing by increasing elasticity and compliance of the reconstructed area. In female patients, the template can be extensively and naturally expanded by the gradually growing uterus, allowing for full-term pregnancy.
