Prepectoral implant-based breast reconstruction provides an alternative to submuscular reconstruction, but the increased acellular dermal matrix (ADM) required has the potential to lead to increased costs and decreased supply of this limited-resource material. We present a method for prepectoral reconstruction utilizing skin-graft meshing techniques to increase the surface area of usable ADM.

Forty-four patients underwent this technique from February 2019 to February 2020. Patient characteristics, operative details, and outcomes, including complications and patient satisfaction utilizing the BREAST-Q, were analyzed. Cost analysis relative to projected cost of nonmeshed techniques was performed.

There were 20 unilateral and 24 bilateral procedures, for a total of 68 breast reconstructions. Mean age was 45.9 years (32-71). Mean implant volume was 485 cm

(265-800), and one sheet of ADM was used for each breast with an average surface area of 161 cm

. Median follow-up was 350 days (212-576). Minor compliing the approach has potential to provide the benefits of prepectoral reconstruction while responsibly preserving product availability and tempering healthcare costs.Venous (cavernous) malformations are commonly seen in the upper limb. There is no consensus in the literature regarding the classification of venous malformations. Patients may be viewed as 2 clinical entities patients with single or multiple lesions. Single venous malformations are sporadic and nonsyndromic, whereas the presence of multiple malformations indicates the presence of either an inherited or an overgrowth (noninherited) disorder. In this article, the author reviews multiple venous malformations of the upper limb, offers a novel classification, and describes their clinical entities along with their genetics and pathogenesis. These clinical entities will also be described by categorizing the cases as per the clinical presentation. Furthermore, the number of cases seen by the author (during an experience of 28 years of practice in Saudi Arabia) in each category will be reviewed to give the reader an overall view of the frequency of presentation of each category to the hand/plastic surgery clinic. Clinically, patients may present in 4 different presentations depending on the distribution of the lesions the late-onset malformations confined to the upper limb; malformations involving the limbs/face/trunk with no mucosal lesions; widespread malformations of the skin, oral mucosa, and the intestine; and venous malformations presenting as a well-known syndrome. The author has seen a total of 84 patients, and the most 2 common presentations were late-onset type (n = 26) and malformations involving the limbs/face/trunk with no mucosal lesions (n = 36). This is the most comprehensive review of multiple venous malformations of the upper limb.Traumatic ear avulsion represents a difficult challenge for all reconstructive surgeons; hence, replantation and reattachment will provide the best aesthetic outcome. However, when microsurgery is not possible, the surgeon must choose the most appropriate alternative method to address the concern. We are reporting a case of a near-total right ear external auricle amputation attached only by small skin bridge. The patient was admitted to our institute 22 hours after sustaining an injury during a motor vehicle collision. He was successfully managed by reattaching the external auricle into the anatomical place, with the repair of cartilage. This was followed by applying a daily protocol for venous congestion with the use of subcutaneous and intradermal injection of low-molecular-weight heparin daily for 10 days with gradual tapering of the dose. The external auricle survived with no complications or morbidity. Subcutaneous and intradermal low-molecular-weight heparin can be used effectively in cases of severe venous congestion of avulsed ear with adequate arterial inflow without causing any morbidity.TriNetX (TriNetX Inc., Cambridge, Mass.) is a federated electronic medical record network. The TriNetX system conducts customized search queries of over 36 million electronic medical records, and returns results in just minutes. To our group's knowledge, TriNetX has not been previously used in plastic surgery research. This study aimed to utilize a continuously updated federated network of 36,000,000 electronic medical records (TriNetX) for comparing 90-day postoperative outcomes between prosthetic breast reconstruction techniques.

Using TriNetX, we analyzed the records of approximately 36 million patients in 31 health care organizations. The de-identified records of 18,744,519 women (age 18-9) were retrospectively screened. OTS514 in vitro A cohort of 4747 patients with a diagnosis of malignant neoplasm of the breast, any stage, having undergone mastectomy, and breast reconstruction with tissue expander was compared with a second cohort of 870 patients diagnosed with malignant neoplasm of the breast, any stage, mastectomy,r all outcomes studied; although this comparison was not statistically significant, we believe it demonstrates a clinically significant finding that single-stage direct-to-implant is at least as safe as the more complicated 2-stage approach.

Cultured epidermal transplantation (JACE) is performed for giant congenital melanocytic nevus (GCMN), but there are few reports on its postoperative course and surgical content or indications. We aimed to investigate the postoperative course of GCMN patients undergoing cultured epidermal autograft transplantation and compare the outcomes between 2 nevus tissue resection methods.

Twelve GCMN patients aged 0 months to 8 years and 9 months were included in this single-center case series study. Cultured epidermal autograft transplantation was performed at 19 sites of the patients' extremities and trunks, after excision of the nevus either by using an electric dermatome, which we initially used in 2017, or by curettage with a sharp spoon and use of a hydrosurgery system (Versajet), which we started performing in 2018. Univariate and multivariate analyses were performed for factors associated with postoperative hypertrophic scar formation.

In all cases, >90% of the grafts survived, and the dark brown color of the nevus was reduced.
