Tumescent anesthesia makes it feasible to perform liposuction in an office setting. There are often patients who desire extensive liposuction on approximately 30% of total body surface area, which means the potential of fluid overload. In this study, the charts of 83 patients undergoing extensive liposuction were retrospectively reviewed.

Introduction: Redundant collagen deposition at sites of healing dermal wounds results in hypertrophic scars. Adipose-derived stem cells (ADSCs) exhibit promise in a variety of anti-fibrosis applications by attenuating collagen deposition. The objective of this study was to explore the influence of an intralesional injection of ADSCs on hypertrophic scar formation by using an established rabbit ear model.

Tumescent anesthesia makes it feasible to perform liposuction in an office setting. There are often patients who desire extensive liposuction on approximately 30% of total body surface area, which means the lidocaine total dose might be over the dosing recommendation. So the segmental infiltration is applied, although the concentration of lidocaine in tumescent fluid is gradually reduced to 0.

Restoration of lymphatic drainage using lymph vessels or tissue grafting is becoming an efficient method for alleviating obstructive lymphedema. However, the lack of ideal lymphatic grafts is the key problem that limits the application of lymphatic transplantation, but now that may be resolved with tissue-engineered lymph vessels. In this study, the feasibility of reconstructing lymph vessels was explored using lymphatic endothelial cells (LECs) combined with polyglycolic acid (PGA) scaffolds.

Objective: To assess the feasibility of interstitial magnetic resonance lymphangiography (IMRL) with intracutaneous injection of gadobenate dimeglumine--a commercially available, non-ionic, extracellular paramagnetic contrast agent.

Methods: We studied 10 patients with lower extremity lymphedema. A mixture of 7.

Objective: To study the efficacy of gene therapy with human vascular endothelial growth factor-c (VEGF-C) on obstructive lymphedema.

Methods: Two animal models of lymphedema were created: one in the right hind limb of adult New Zealand white rabbits and the other in SD mouse tail. Each model was randomly divided into two groups to receive intradermal injection of either VEGF-C gene (experimental group), or saline(control group).

Objective: To observe treatment effects of primary lower limb lymphedema using ultrasonic assisted liposuction.

Methods: Internal ultrasonic liposculpture system combined postoperative continual elastic stockings or bandages were used for reducing lymphatic burdens of the affected limbs by partly removal of lymphedematous tissues.

Results: Edema regression in the affected limbs were obvious at 2 weeks postoperative and kept to stable without recurrence during 1 year follow-up.

Objective: This article reports the design and application of a free reverse preauricular flap for one-stage reconstruction of nasal defects.

Methods: A preauricular flap was designed according to the nasal defect, which was harvested with the reverse superficial temporal vessels as its vascular pedicle. The flap size ranged from 3.

Objective: A reversed superficial temporal artery auricular flap was presented to explore a new method for reconstructing the defects of the distal nose by microsurgical techniques.

Methods: A reversed superficial temporal artery auricular flap had been used on fifteen patients with nasal defects, including thirteen patients with alar defects and two patients with nasal tip defects. The reversed superficial temporal vessels of the flap were anastomosed with the recipient facial vessels.

Objective: To investigate the possible influence of the impairment of lymph fluid on the metabolism of hyaluronic acid (HA) in the lymphedematous skin tissue.

Methods: Tissue fluid was collected in lymphedematous limbs and the contralateral healthy limbs of 39 patients and HA content was measured with radioimmunoassay. The protein contents were also measured.

Objective: To explore the applications of ipsilateral reverse fascial pedicled posterolateral lower leg flap in foot defect repair.

Methods: A fasciocutaneous flap was designed over the gastrocnemius muscle to repair the defects in the foot or the lower third of the leg. The flap was based on a perforator branch between the lateral malleolus and the Achilles tendon, coming from the vessel network of the ankle as well as the deep fascia.
