Background: The authors hypothesized that optimization of nipple-areolar reconstruction using full-thickness skin graft and cartilage graft can be completed safely in a single-stage procedure.

Methods: A retrospective analysis of abdominal-based flap breast reconstruction patients who underwent nipple-areolar reconstruction (NAR) using the modified double-opposing tab (mDOT) flap technique was conducted. Complication rates were compared between patients who underwent NAR in a traditional staged procedure versus a single stage.

Background: Molecular profiling using breast cancer subtype has an increasing role in the multidisciplinary care of the breast cancer patient. The authors sought to determine the role of breast cancer subtyping in breast reconstruction and specifically whether breast cancer subtyping can determine the need for postmastectomy radiation therapy and predict recurrence-free survival to plan for the timing and technique of breast reconstruction.

Methods: The authors reviewed prospectively collected data from 1931 reconstructed breasts in breast cancer patients who underwent mastectomy between November of 1999 and December of 2012.

Unlabelled: The most commonly chosen flaps for delayed breast reconstruction after postmastectomy radiation therapy (PMRT) are abdominal-based free flaps (ABFFs) and pedicled latissimus dorsi (LD) musculocutaneous flaps. The short-and long-term advantages and disadvantages of delayed ABFFs versus LD flaps after PMRT remain unclear. We hypothesized that after PMRT, ABFFs would result in fewer postoperative complications and a lower incidence of revision surgery than LD flaps.

Background: Infections of breast tissue expander (TE) are complex, often requiring TE removal and hospitalization, which can delay further adjuvant therapy and add to the overall costs of breast reconstruction. Therefore, to reduce the rate of TE removal, hospitalization, and costs, we created a standardized same-day multidisciplinary outpatient quality improvement protocol for diagnosing and treating patients with early signs of TE infection.

Methods: We prospectively evaluated 26 consecutive patients who developed a surgical site infection between February 2013 and April 2014.

Background: The authors hypothesized that obese patients would experience fewer complications after oncoplastic breast reconstruction following partial mastectomy than after immediate breast reconstruction following total mastectomy.

Methods: Complication rates were compared for oncoplastic breast reconstruction versus immediate breast reconstruction (with either implants or autologous tissue) in consecutive obese patients (body mass index ≥ 30 kg/m(2)) treated at a single center between January of 2005 and April of 2013. Logistic regression was used to analyze the associations between patient and surgical characteristics and postoperative outcomes.

Background: Although many plastic surgeons perform autologous fat grafting (lipofilling) for breast reconstruction after oncologic surgery, it has not been established whether postoncologic lipofilling increases the risk of breast cancer recurrence. The authors assessed the risk of locoregional and systemic recurrence in patients who underwent lipofilling for breast reconstruction.

Methods: The authors identified all patients who underwent segmental or total mastectomy for breast cancer (719 breasts) (i.

Purpose: Concerns exist regarding breast cancer patients' access to breast reconstruction, which provides important psychosocial benefits.

Patients And Methods: Using the MarketScan database, a claims-based data set of US patients with employment-based insurance, we identified 20,560 women undergoing mastectomy for breast cancer from 1998 to 2007. We evaluated time trends using the Cochran-Armitage test and correlated reconstruction use with plastic-surgery workforce density and other treatments using multivariable regression.

Background: Irradiation to free flaps following immediate breast reconstruction has been shown to compromise outcomes. The authors hypothesized that irradiated muscle-sparing free transverse rectus abdominis musculocutaneous (TRAM) flaps experience less fat necrosis than irradiated deep inferior epigastric perforator (DIEP) flaps.

Methods: The authors performed a retrospective study of all consecutive patients undergoing immediate, autologous, abdomen-based free flap breast reconstruction with muscle-sparing free TRAM or DIEP flaps over a 10-year period at their institution.

Background: The authors examined the safety of a protocol for planned skin-preserving delayed breast reconstruction after postmastectomy radiotherapy with placement of a tissue expander for patients with locally advanced breast cancer (stages IIB and III).

Methods: The authors compared 47 patients treated according to the protocol between December 2003 and May 2008 with 47 disease-stage-matched control patients who underwent standard delayed reconstruction after postmastectomy radiotherapy (no skin preservation or tissue expander) during the same period.

Results: Protocol-group complication rates were 21 percent for skin-preserving mastectomy and placement of the expander (stage 1), 5 percent for postmastectomy radiotherapy, 25 percent for expander reinflation after radiotherapy, and 24 percent for skin-preserving delayed reconstruction.
