BACKGROUND AND AIMS Reduction mammaplasty is a popular procedure in plastic surgery. Occasionally, occult invasive breast carcinoma or findings demonstrating increased risk of breast cancer occur in reduction mammaplasty specimens. The incidences have been studied elsewhere, but in Finland, the data on this subject are lacking. Our aim was to analyze the(More)
BACKGROUND Autologous fat grafting has become a frequent, simple, reproducible and low-risk technique for revisional or partial breast reconstruction. The presented European multicenter study describes an optimized treatment and follow-up protocol for the de novo breast reconstruction after total mastectomy by lipotransfer alone. METHODS A retrospective(More)
BACKGROUND It is controversial whether surgical denervation of the thoracodorsal nerve should be performed in breast reconstruction with a myocutaneous latissimus dorsi flap. Denervation may prevent discomforting symptoms caused by muscle contraction, but the flap may also lose significant volume. The authors prospectively evaluated the influence of(More)
Skeletal muscle is prone to injury upon trauma or nerve damage. In reconstructive surgery, it is an interesting spare part. Fortunately, skeletal muscle is capable of extensive regeneration. Satellite cells, quiescent myogenic precursor cells, become activated following muscle injury: they divide and form myoblasts, fuse into myotubes, and finally mature to(More)
BACKGROUND : We report microvascular free tissue transfers in pediatric patients in a retrospective series. METHODS : Forty-six children were treated in collaboration between the departments of Pediatric Surgery and Plastic Surgery, Helsinki University Hospital between 1986 and 2004 for microvascular free flap surgery. Trauma, tumor resection, congenital(More)
BACKGROUND Satellite cell proliferation, reinnervation, and revascularization were studied in human nonreinnervated free microvascular muscle flaps to characterize mechanisms of muscle regeneration after flap surgery. MATERIALS AND METHODS Patient biopsies (n = 19) were taken at operation and five timepoints up to 9 months after operation, and(More)
The purpose of this study was to characterize microneurovascular (MNV) muscle transplants immunohistochemically up to 10 years after transfer. Histological data was related to long-term functional outcome. The study comprised 17 patients with a mean age of 41 years suffering from complete unilateral long-lasting facial paralysis. A two-stage procedure was(More)
BACKGROUND AND AIM It has been shown that the myocutaneous latissimus dorsi flap volume and consistency remain mainly the same regardless the nerve is cut or not in breast reconstruction. It is controversial how big an impact the flap innervation has on the muscle activity of the flap. The aim of the study was to prospectively evaluate the influence of(More)
Vascularization and angiogenicity of human nonvascularized nerve grafts in the second stage of facial reanimation were studied. Immunohistochemistry for endothelial markers (CD-31) and vascular endothelial growth factor (VEGF) and its receptors Flt-1 and Flk-1 was performed on distal end biopsies from 35 cross-facial nerve grafts. In grafted nonvascularized(More)
BACKGROUND AND AIMS Reduction mammaplasty is an increasingly common plastic surgical procedure. In the United States, majority of breast reductions are performed as outpatient surgery. In European public health care, outpatient breast reductions have still been rare. Our aim was to retrospectively determine clinical outcome and the success rate of(More)
