Methods: The low was used only for cases with moderately sized breasts and reliable perforators way umbilicus. flap's lower border on pubic rim upper usually...
Abstract Extracellular matrix (ECM) remodeling dynamically occurs to accommodate adipose tissue expansion during obesity. One non-fibrillar component of ECM, biglycan, is released from the in response stress; soluble form biglycan binds toll-like receptor 2/4 on macrophages, causing proinflammatory cytokine secretion. To investigate pattern and regulatory properties expression human tissues context obesity its related diseases, we recruited 21 non-diabetic obese women, 11 type 2 diabetic 59...
In Brief Fat necrosis in transverse rectus abdominis musculocutaneous (TRAM) flap is considered to be mainly affected by blood supply. This prospective study compares the incidence of fat between zones II and III 400 consecutive patients who had undergone unipedicled TRAM breast reconstruction. Fifty-eight (14.5%) suffered from necrosis, 7 2 separate nodules. Fifty-four occurred zone II, 10 III, 1 I. The was significantly higher than (P < 0.001). weight mastectomy specimen relative amount...
Although free flap has largely replaced pedicled transverse rectus abdominis musculocutaneous (TRAM) flap, the latter also evolved by increased understanding of anatomy and physiology. We report outcomes in 500 consecutive TRAM Asian patients performed a single surgeon, providing incidences complications ideas prevention. Fascia was minimally harvested with full width muscle. The eighth intercostals nerve severed back-cut made at lateral belly. Anterior sheath directly repaired. Breast...
Nipple-sparing mastectomy (NSM) is gaining popularity due to its superior aesthetic results. When reconstructing the breast with free abdominal tissue transfer, we must readdress recipient vessel, because NSM can cause difficulty in access chest vessel.Between June 2006 and March 2011, a total of 92 women underwent transfer. A lateral oblique incision was used for nipple-sparing mastectomy. For vessels, internal mammary vessels were chosen if flap did not block vessels. If it did,...
Background No consensus has been reached regarding the outcome of management local recurrence after transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction. This study demonstrated presentation, management, and outcomes immediate TRAM Methods A comparison was conducted among 1,000 consecutive patients who underwent reconstruction with a pedicled (TRAM group) 3,183 only modified radical mastectomy without (MRM from January 2001 to December 2009. The treatment, including...
Background Numerous procedures are available for nipple reconstruction without a single gold standard. This study presents method reducing donor-site morbidity in using composite graft after transverse rectus abdominis musculocutaneous flap breast reconstruction. Methods Thirty-five patients who underwent technique between July of 2001 and December 2009 were enrolled this study. To reduce the donor site morbidity, superior or superior-medial half dome harvesting was applied preserving...
Arteriovenous malformations are high flow lesions that remain a challenge in the field of plastic surgery, interventional radiology, and neurosurgery. This is especially true for large requiring comprehensive team approach. From March 2001 to August 2004, six patients with arteriovenous malformation having extensive involvement skin underwent selective embolization followed by resection reconstruction anterolateral thigh perforator flap. The age ranged from 22 43 years (average, 29 years);...
Objective The traditional unilateral or bilateral buccogingival bicoronal approach often seems to impose limitations on achieving complete resection and reconstruction of the extensive midfacial fibrous dysplasia. Therefore, we hypothesized that degloving could be used for correction maxillary dysplasia, which has been primarily paranasal sinus lesions nasopharyngeal tumor. Methods study involved 5 maxillofacial dysplasia patients who underwent a surgical procedure. There were 4 male 1...
Topical anesthetics, such as eutectic mixture of local anesthetics (EMLA) cream, can be applied to reduce pain before minor procedure.

Bromidrosis is a condition of abnormal offensive body odor caused mostly by apocrine gland secretion from the axilla. Although no morbid sequelae are known, can be disturbing enough to cause social impairment and psychological distress. Medical care available but temporary yields limited clinical benefit. Surgical treatment may provide more definite remedy through reduction gland. However, there risks for complication following surgical such as subdermal excision, subcutaneous shaving, en...
Abdominal wall free flaps are used most frequently in autologous breast reconstruction, and these require intact robust deep inferior epigastric perforator (DIEP) vessels. Pfannenstiel incisions often present during preoperative visits for reconstruction could potentially signal compromised blood supply to the lower abdominal wall. In this study, we compared number of DIEP vessels between patients with without undergoing reconstruction.A retrospective review medical records was performed...
