Background: The requirement for postmastectomy radiation therapy (PMRT) at the time of mastectomy is often unknown. Autologous reconstruction is preferred in the setting of radiotherapy by providing healthy vascularized tissue to the chest. To maximize mastectomy skin preservation, tissue expander (TE) placement maintains the breast pocket until definitive reconstruction. This study aims to compare outcomes of skin-preserving delayed versus standard delayed autologous breast reconstruction in the setting of PMRT. Methods: A retrospective review of a prospective database was performed of two patient cohorts at a single center between 2006 and 2016. Inclusion criteria were locally advanced breast cancer patients who completed PMRT and free autologous reconstruction. Primary outcomes were major intraoperative and postoperative TE and flap complications. Results: Over 10 years, 241 patients underwent mastectomy and PMRT. Standard delayed autologous breast reconstruction was performed in 131 breasts (non-TE group). Skin-preserving delayed autologous reconstruction was performed in 113 breasts (TE group). The TE group was associated with a higher incidence of intraoperative complications during flap reconstruction ( P = 0.002) and had a higher venous thrombosis incidence than the non-TE cohort ( P = 0.007). Other major postoperative complications were not significantly different between the two groups. TE patients had 7.5 times higher risk of intraoperative complications and an 18.6% TE loss rate. Conclusions: We identified higher intraoperative flap complications and a high rate of TE loss in patients who underwent skin-preserving delayed autologous breast reconstruction. The benefit of mastectomy skin preservation needs to be weighed against the increased risk of TE loss and higher rates of flap thrombosis.

Summary:Craniomaxillofacial reconstruction using virtual surgical planning, computer-aided manufacturing, and new microsurgical techniques optimizes patient-specific and defect-directed reconstruction. A 3D customized free deep circumflex iliac artery (DCIA) flap with intraoral anastomoses was performed on a 23-year-old man with a posttraumatic right zygomatico-maxillary defect with failure of alloplastic implant reconstruction. An osseous iliac crest flap was sculpted based on a customized 3D model of the mirror image of the patient’s unaffected side to allow for perfect fit to the zygomatico-maxillary defect. An intraoral dissection of the facial artery and vein was performed within the right cheek mucosa and allowed for end-to-end microvascular anastomoses. 3D preoperative planning and customized free DCIA osseous flap combined with an intraoral microsurgical technique provided restoration of facial esthetics and function without visible scars. In cases where zygomatico-malar reconstruction by alloplastic material fails, a customized free DCIA osseous flap can be designed by virtual surgical planning to restore facial appearance and function.

The authors report the case of a 30-year-old male with 52% TBSA high-voltage electrical injury of the upper half of the body. Injuries included a cervical burn with associated alteration of the left brachial plexus as well as extensive soft tissue burn of the right hand. Three months later, he developed osteomyelitis of the right thumb metacarpal bone requiring amputation proximal to the metacarpophalangeal joint. Following initial management, the patient had a permanent distal left upper extremity paralysis with nonfunctional but relatively undamaged ipsilateral hand digits. The right hand remained functional with four intact digits and a thumb stump. Usually, late reconstruction of proximal thumb amputation is performed by pollicization or free toe transfer procedures. In this particular case, right thumb reconstruction was done by free transfer of the left little finger. Four months postoperatively, the patient demonstrated a functional pinch between the reconstructed thumb and the ipsilateral digits along with improving sensation. This uncommon surgical procedure restored a functional thumb with minimal donor site morbidity. The decision-making process and operative technique are presented in detail along with a review of the thumb reconstruction literature.
