In the treatment of sarcoma, the reconstructive surgeon must consider not only limb salvage but also functional reconstruction. The aim of this study was to evaluate a functional reconstruction of a dorsal forearm defect after sarcoma resection using immediate tendon transfer. Patients who underwent reconstruction of a dorsal forearm defect after sarcoma resection with an immediate tendon transfer between 1997 and 2019 at our hospital were included in this retrospective study.

Reconstruction of a defect in the labial area has to be performed by taking account of the shape of the labial area and urogenital function. The gracilis myocutaneous flap and the gluteal fold flap are commonly used reconstructive procedures, but sometimes these flaps are too bulky and cause a deviation of the urination stream and/or deformity of the reconstructed site. In this report, we present our unique method of reconstruction using a contralateral labia majora sharing perforator flap.

Background: In the setting of the reconstruction for a large defect, we must make the maximum use of the limited human tissue with the minimum damage. In this article, we report on reconstruction using a combination of three-skin paddle latissimus dorsi and a scapular flap for a large defect after soft tissue sarcoma resection to minimize donor site morbidity.

Methods: From 2000 to 2012, six patients underwent primary reconstruction using free or pedicled triple-lobe combined latissimus dorsi and scapular flap after wide resection of soft tissue sarcoma.

A 2-stage breast reconstruction using a breast tissue expander and prosthesis is a simple method of breast reconstruction with little donor-site morbidity and short surgery time. In this report, we present a rare case of chest wall deformity, which appeared during breast skin expansion with tissue expander. We present a case of a 31-year-old woman who underwent a 2-stage breast reconstruction with a tissue expander and breast prosthesis.

Fingertip replantation is a technical challenge for microsurgeons. For successful fingertip replantation, it is important to monitor the replanted fingertip vascularity for the early detection and revision of vascular compromise. Laser speckle contrast imaging (LSCI) is a camera-based technique that measures the perfusion by illuminating the tissue with a 785-nm-wavelength divergent laser beam.

We encountered a very rare condition where the patient had a lymphocele under the skin envelope of the breast following mastectomy during the course of breast reconstruction with a tissue expander. The incidence rate of axillary lymphoceles is reported as 2.2-50% in breast cancer patients, but there have been no reports mentioning lymphoceles under the breast skin during the course of breast reconstruction with a prosthesis.

Background: Patients with facial fracture or head and neck surgery sometimes suffer from infraorbital nerve injury. This injury results in severe hemilateral numbness in the midfacial area. The infraorbital nerve ends with two major branches; the infra nasal branch (INB) and superior labial branch (SLB).

Objective: The aim of this study was to identify the risks and benefits of the stepladder V-Y advancement medial thigh flap for vulvovaginal reconstruction in comparison to direct skin closure.

Methods: Fifty-four patients with vulvar cancer treated in our hospital between 1992 and 2013 were enrolled in this study. The cohort group (group A) consisted of 25 patients who underwent surgery from August 2006 until April 2013.

We present the current perspective on reconstructive surgery for soft tissue tumors, especially in the extremities, based on our large series. A total of 1,813 patients with bone and soft tissue sarcomas underwent surgery at our hospital between 1978 and 2011. Reconstructive operations were performed by plastic surgeons.

In free tissue transfers, preventing microvascular thrombosis is the first priority to achieve a successful result. Numerous protocols exist for preventing thrombosis postoperatively. We performed continuous local intraarterial infusion of anticoagulants in 11 patients undergoing wide resection of malignant soft tissue tumors, followed by primary microvascular reconstruction in the lower limb.

The defects following soft-tissue or bone malignancies resection tend to be wide and composite at the region of ankle, and reconstruction of the defects is a difficult task. Between 1982 and 2007, we performed reconstruction for the defects of the ankle region in seven patients. All of the patients underwent free tissue transfer, and the selected methods are different for each case.

Many surgical procedures have been reported for vulvoperineal reconstruction following cancer resection. These include the use of skin grafts, local skin flaps, muscle flaps and fasciocutaneous flaps. Among them, V-Y advancement flap from the medial thigh region has been widely used.
