Reconstruction for Defects of Total Nail Bed and Germinal Matrix Loss with Acellular Dermal Matrix Coverage and Subsequently Skin Graft

Malignant melanoma in the hand: current evidence and recommendations

Malignant melanoma is the leading cause of death from skin cancer. In spite of significant advances in the management of melanoma with the advent of sentinel lymph node biopsy (SLNB) and adjuvant oncological therapies, the death rate continues to increase worldwide. Melanoma in the hand poses additional diagnostic and management challenges. Consequently, these tend to present at a later stage and are associated with a poorer prognosis. It is imperative that hand surgeons treat any pigmented hand lesion with suspicion to ensure rapid diagnosis and treatment. This article outlines the presentation of melanoma, and how to investigate suspicious pigmented lesions of the hand and digits. It guides hand surgeons in their approach to melanoma of the hand, outlining the multidisciplinary team approach as well as current standard surgical and reconstructive options to optimize outcomes.

Application of Artificial Dermis Combined With a Medial Flap From the Second Toe to Repair Degloving Injury of the Fingertip

There is no standard technique for repairing degloving injuries of the fingertip. Nail bed flap transplantation is a common surgical technique to address this injury, but this procedure inevitably damages the donor site in the toe. This article describes a surgical technique that can restore the appearance of the injured fingernail and preserve the length and function of the injured finger without damaging the toenail.

Comparative efficacy of different reconstruction methods after wide local excision of the nail unit: A retrospective study

BACKGROUND

Wide local excision (WLE) of the nail unit is widely used in treating in situ and minimally invasive malignant subungual tumours. After WLE, diverse reconstruction methods have been reported. However, the best repair method has yet to be determined.

OBJECTIVE

To compare the repair effects and postoperative morbidity of secondary intention healing (SIH), artificial dermis grafting combined with secondary intention healing (ADGSIH) and full-thickness skin grafting (FSG) after WLE of the nail unit.

METHODS

We retrospectively reviewed 21 patients who underwent WLE of the nail unit. The re-epithelializing time, functional and cosmetic outcomes, postoperative complications and patients' satisfaction were assessed from the follow-up records.

RESULTS

The FSG group showed more rapid healing and better functional and cosmetic outcomes than the SIH and ADGSIH groups. The ADGSIH and FSG groups showed significant pain relief compared to the SIH group. No serious early and late postoperative complications were reported. The median follow-up period was 26 months, and no recurrence was observed. All patients were satisfied with the treatment.

CONCLUSIONS

FSG after the WLE of the nail unit is a therapeutic option with convenient application, significant pain relief, rapid recovery and satisfying functional and cosmetic outcomes.

Acellular dermal matrix in reconstructive surgery: Applications, benefits, and cost

Modern tissue engineering has made substantial advancements that have revolutionized plastic surgery. Acellular dermal matrix (ADM) is an example that has gained considerable attention recently. ADM can be made from humans, bovines, or porcine tissues. ADM acts as a scaffold that incorporates into the recipient tissue. It is gradually infiltrated by fibroblasts and vascularized. Fortunately, many techniques have been used to remove cellular and antigenic components from ADM to minimize immune system rejection. ADM is made of collagen, fibronectin, elastin, laminin, glycosaminoglycans, and hyaluronic acid. It is used in critical wounds (e.g., diabetic wounds) to protect soft tissue and accelerate wound healing. It is also used in implant-based breast reconstruction surgery to improve aesthetic outcomes and reduce capsule contracture risk. ADM has also gained attention in abdominal and chest wall defects. Some studies have shown that ADM is associated with less erosion and infection in abdominal hernias than synthetic meshes. However, its higher cost prevents it from being commonly used in hernia repair. Also, using ADM in tendon repair (e.g., Achilles tendon) has been associated with increased stability and reduced rejection rate. Despite its advantages, ADM might result in complications such as hematoma, seroma, necrosis, and infection. Moreover, ADM is expensive, making it an unsuitable option for many patients. Finally, the literature on ADM is insufficient, and more research on the results of ADM usage in surgeries is needed. This article aims to review the literature regarding the application, Benefits, and costs of ADM in reconstructive surgery.

Fingertip reconstruction with a subcutaneous flap and composite graft composed of nail bed and volar pulp skin

Background

Fingertip injuries are very common; however, the reconstruction of volar pulp defects with nail bed defects is challenging in the absence of the amputated segment. We reconstructed fingertip amputations with nail bed defects using a new surgical approach: a subcutaneous flap and composite graft.

Methods

We treated 10 fingertip amputation patients without an amputated segment, with exposed distal phalangeal bone and full-thickness nail bed defects between February 2018 and December 2020. All patients underwent two-stage surgery: in the first stage, a subcutaneous flap was performed to cover the exposed distal phalanx, and in the second stage, a composite graft, consisting of nail bed, hyponychium, and volar pulp skin, was applied over the subcutaneous flap.

Results

All flaps survived and all composite grafts were successful. The wounds healed without any significant complications, including the donor site. The average follow-up duration was 11.2 months (range, 3–27 months). The new nail and the shape of the volar pulp were evaluated during follow-up. All patients were satisfied with their natural fingertip shapes and the new nails did not have any serious deformities.

Conclusions

A subcutaneous flap in combination with a composite graft fitting the shape of the defect could be another option for fingertip injuries without amputated segments.

Mimical reconstruction and aesthetic repair of the nail after resection of subungual melanocytic nevus

Background

This study aimed to report the outcomes of mimical reconstruction and aesthetic repair of the nail.

Methods

When the pigmented bands were more than 1/2 the width of the whole nail, mimical reconstruction of the nail was performed, with a lateral toe pulp island flap covering the wound via the subcutaneous channel. If the pigmented bands were 1/4 to 2/5 the width of the entire nail, aesthetic repair of the nail was carried out by split-thickness excision under a microscope.

Results

The average age of patients at the time of surgery was 14.5 years. Five patients had lesions on their toes, while three had lesions on their fingers. There were no post-operative complications. All toenails of the five patients who had undergone mimical reconstruction exhibited a well-settled flap. The nails of the three patients who underwent aesthetic repair displayed no nail malnutrition or deformity, and all nails had an aesthetic appearance.

Conclusions

Both mimical reconstruction and aesthetic repair of the nail following resection of subungual melanocytic nevus are reliable and feasible. The “like tissue” repairs of complex nail defects appear to be satisfactory. All patients had excellent aesthetic outcomes.
