INTRODUCTION: There is significant variability in the location and management of drains in breast reconstruction, with most surgeons attempting to shorten the duration of drains while preventing complications possibly related to early removal. The aim of this work was to compare our experiences with placement of 1 versus 2 drains in tissue expander breast reconstruction. METHODS: This is a retrospective cohort study comparing 2 groups of patients after breast tissue expander placement in a complete submuscular pocket and without the use of acellular dermal matrix...

BACKGROUND: Recent data suggest an increased risk for infection when acellular dermal matrix is used in breast reconstruction. This may be because some acellular dermal matrices are actually not terminally sterilized but are instead "aseptically processed." This study evaluates aseptic and sterile matrices for evidence of bacterial contamination and whether or not terminal sterilization affects matrix collagen architecture and stem cell ingrowth. METHODS: Five separate samples of 14 different matrices were analyzed by fluorescent in situ hybridization using a bacterial DNA probe to detect bacterial DNA on the matrices...

Although ankle arthrodesis is the reference standard for end-stage ankle arthritis, loss of mobility and adjacent joint arthritis are consequences that alternatives to arthrodesis attempt to avoid. The purpose of the present study was to report the clinical results of interpositional arthroplasty using acellular dermal matrix in 4 patients (age 32 to 42 years) for the treatment of advanced ankle osteoarthritis. The primary findings included relief of pain, with improvement in tibiotalar joint range of motion from a mean of 16...

INTRODUCTION: Acellular dermal matrix (ADM) assisted implant-based breast reconstruction (IBBR) has grown in popularity over traditional submuscular techniques. Numerous human, bovine or porcine derived ADMs are available with the type used varying considerably worldwide. Yet, comparative evidence for the efficacy of different ADMs particularly xenogenic is limited. This study directly compares early outcomes of porcine (Strattice™) and bovine (Surgimend™) ADMs in IBBR. METHOD: Retrospective study of sequential experience of immediate IBBR using Strattice or Surgimend ADM...

Acellular dermal matrix allografts (ADMs) have been hypothesized to create a zone of immobile connective tissue (ICT) extending apical to the mucogingival junction (MGJ). This 12-month prospective randomized trial investigated the presence of ICT after the use of two commercially available ADMs with coronally advanced flaps in the treatment of Miller Class I and II recession defects. This study demonstrated that the use of either type of ADM resulted in predictable root coverage and a zone of ICT extending apical to the MGJ by 1...

BACKGROUND: Placement of a closed suction drain is a common cause of patient complaints, such as postoperative pain or discomfort following immediate expander-implant breast reconstruction. This study aims to identify factors that affect drainage volume, time to drain removal, and seroma formation. METHODS: A retrospective chart review of prospectively collected data was conducted on patients who underwent immediate expander-implant breast reconstructions following nipple-sparing or skin-sparing mastectomy without skin excision (nipple areolar complex excision only) between February 2010 and April 2015...

BACKGROUND/AIMS: Bone marrow Mesenchymal stem cells (MSCs) are promising for promoting cutaneous wound healing through reinforcing cellular processes. We evaluated the effect of GFP-tagged MSCs transplantation on skin regeneration in excisional wounds in mice. METHODS: MSCs from GFP-labeled transgenic mice were co-cultured with acellular dermal matrix (ADM) scaffolds, and MSC-ADM scaffolds were transplanted into surgical skin wounds of BALB/c mice. After implantation, the survival and behavior of MSCs were examined by second harmonic generation and two-photon excitation fluorescence imaging, western blotting and DNA amplification and sequencing...

BACKGROUND: Nipple sparing mastectomy (NSM) with immediate prosthetic reconstruction is routinely performed due to excellent aesthetic results, and safe oncologic outcomes. Typically, subpectoral expanders are placed, but in select patients, this can lead to significant postoperative pain and animation deformity, due to pectoralis major muscle disinsertion and stretch. Prepectoral reconstruction is a technique that eliminates dissection of the pectoralis major, by placing the prosthesis completely above the muscle with complete acellular dermal matrix (ADM) coverage...

Paraffinoma is a destructive complication of paraffin oil injection, usually associated with massive tissue destruction, thus requiring radical surgery and subsequent complex reconstruction. Although breast and penile paraffinomas have been widely described and their management is quite standardized, paraffinomas of the knee are still rare and only few case reports or small case series are available in the current literature. We describe the case of a 77-year-old man with a large paraffinoma of the right knee that occurred after self-injection of paraffin oil, 58 years before...
