The extended brow lift: the toucan technique   总被引:1,自引:0,他引:1  
Brow ptosis is the main consequence of aging in the upper third of the face. Many methods have been described to correct it: skin excisions of the brow hairline, skin excisions of the forehead natural creases, skin trimmings of the temporal, coronal, or forehead hairline flaps, and endoscopic methods [1,15,17,18,24,26,27]. The authors created a procedure which is based on a forehead-temporal subcutaneous flap and a muscular relocation. It treats the brow ptosis and its surrounding area—temporal ptosis, upper and lower lateral eyelid ptosis, crow's feet—and at the same time improves the sclera show or ectropion. The method preserves the sideburn and the temporal hairline and can reduce the width between the temporal hairline and the lateral end of the eyebrow. The method produces maximum improvement, with high-quality scars and minimal evidence of surgery. The procedure is called "The Toucan Technique," due to the shape of the skin resection which looks like a toucan bird [11,13,14].  相似文献

Preoperative biliary drainage may improve the cytokine and acute-phase response derangements observed in patients with obstructive jaundice. We conducted a prospective longitudinal, before-after trial in our 600-bed teaching hospital. Twenty-four patients with obstructive jaundice were investigated, 11 with benign obstruction and 13 with malignant disease. Endoscopic internal biliary drainage was performed in all patients (7 by papillotomy and 17 by endoprostheses). Endotoxin, tumor necrosis factor alpha (TNF-a), interleukin-6 (IL-6), nitric oxide production, and C-reactive protein (CRP) were determined at admission and on days 2 and 7 after internal biliary drainage was accomplished. Bile cultures were obtained before and at the time of drainage. Endotoxin, IL-6, TNF-a, and CRP were significantly higher in patients with cancer. After internal drainage, endotoxin (11.4 vs. 2 EU/L; p <0.05), TNF-a (87.5 vs. 48 pg/ml; p = 0.03), and IL-6 (324 vs. 232 pg/ml; p <0.05) plasma levels decreased significantly in the early postdrainage period in patients with cancer. Endotoxin, cytokines, as well as the CRP plasma values, however, increased again on day 7 after drainage. This trend was less marked in patients with benign obstruction. Patients with positive bile cultures after drainage displayed higher levels of CRP (115 vs. 62 mg/L; p = 0.03), IL-6 (598 vs. 330 pg/ml; p = 0.04), and endotoxin (10.6 vs. 4.8 EU/L; p = 0.02) than those with negative bile cultures. Biliary tract obstruction is associated with an increase in endotoxin levels, a positive acute-phase response, and plasma cytokine elevation. After biliary drainage a transitory improvement of these alterations was observed, although values remained high 1 week postdrainage. These findings were associated with positive bile cultures.  相似文献

Drilling of the femoral tunnel with the transtibial (TT) technique is widely used in bone-patellar tendon-bone (BPTB) anterior cruciate ligament (ACL) reconstruction. Recent studies suggest higher knee stability with the use of the anteromedial portal (AMP). The purpose of this study was to compare functional and clinical outcomes of BPTB ACL reconstruction using the TT or the AMP technique for drilling the femoral tunnel. All ACL reconstructions between January 2003 and April 2006 were approached for eligibility. Forty-seven patients met inclusion criteria (21 TT group and 26 AMP group). Blinded assessments of IKDC score, knee stability and range of motion, one-leg hop test, mid-quadriceps circumference, VAS for satisfaction with surgery, Lysholm and Tegner scores, and SF-12 questionnaire were obtained for both groups. Data on preoperative and postoperative surgical timing were retrospectively reviewed through the charts. The AMP group demonstrated a significantly lower recovery time from surgery to walking without crutches (p < 0.01), to return to normal life (p < 0.03), to return jogging (p < 0.03), to return training (p < 0.03), and to return to play (p < 0.03). Knee stability values measured with KT-1000, Lachman test, pivot-shift sign, and objective IKDC score assessments were significantly better for the AMP compared to TT group (p < 0.002, p < 0.03, p < 0.02, p < 0.015, respectively). No differences were found for VAS for satisfaction with surgery, Lysholm, Tegner, and SF-12 between both groups. The use of the AMP technique significantly improved the anterior-posterior and rotational knee stability, IKDC scores, and recovery time from surgery compared to the TT technique.  相似文献

Background:

The characteristics of the ideal type of mesh are still being debated. Mesh shrinkage and fixation have been associated with complications. Avoiding shrinkage and fixation would improve hernia recurrence rates and complications. To our knowledge, this is the first study of a device with a self-expanding frame for laparoscopic hernia repair.

Methods:

Six Rebound Hernia Repair Devices were placed laparoscopically in pigs. This device is a condensed polypropylene, super-thin, lightweight, macro-porous mesh with a self-expanding Nitinol frame. The devices were assessed for adhesions, shrinkage, and histological examination. Laboratory and radiologic evaluations were also performed.

Results:

The handling properties of the devices facilitated their laparoscopic placement. They were easily identified with simple x-rays. The mesh was firmly integrated within the surrounding tissue. One device was associated with 3 small adhesions. The other 5 HRDs had no adhesions. We noted no shrinkage or folding. All devices preserved their original size and shape.

Conclusions:

At this evaluation stage, we found that the Rebound Hernia Repair Device may serve for laparoscopic hernia repair and has favorable handling properties. It prevents folding and shrinkage of the mesh. It may eliminate the need for fixation, thus preventing chronic pain. The Nitinol frame also allowed radiologic evaluation for gross movement. Further studies will be needed to evaluate its clinical application.  相似文献

BACKGROUND: Recent studies have shown that adrenomedullin (AM) and AM-binding protein-1 (AMBP-1) possess anti-inflammatory properties in sepsis. We hypothesized that administration of AM/AMBP-1 after gut ischemia-reperfusion (I/R) downregulates inflammatory cytokines and attenuates tissue injury. METHODS: Male Sprague-Dawley rats (275-325 g) were used. Gut ischemia was induced by placing a microvascular clip across the superior mesenteric artery (SMA) for 90 minutes. Upon release of the SMA clamp, the animals were treated by AM (12 microg per kilogram of body weight) and AMBP-1 (40 microg per kilogram of body weight) in combination, or vehicle (1 mL 0.9% NaCl) over 30 minutes via a femoral vein catheter. The animals undergoing sham operation or ischemia for 90 minutes only, did not receive AM/AMBP-1 treatment. At 60 minutes after the completion of the treatment (ie, 90 minutes after reperfusion), blood samples were collected. Plasma AM and AMBP-1 were measured by radioimmunoassay and Western blot analysis, respectively. Serum levels of TNF-alpha, interleukin (IL)-1beta, IL-6, IL-10, transaminases (ie, alanine aminotransaminase, aspartate aminotransaminase), lactate, and creatinine were determined with the use of enzyme-linked immunosorbent assay and other standard methods. In additional groups of animals, the 10-day survival rate was recorded after gut I/R. RESULTS: Ischemia alone was sufficient to downregulate both AM and AMBP-1. Unlike AMBP-1 that remained decreased, AM levels increased significantly after reperfusion. I/R but not ischemia alone significantly increased serum levels of inflammatory cytokines. Moreover, I/R-induced tissue injury was evidenced by increased levels of transaminases, lactate, and creatinine. Administration of AM/AMBP-1 after ischemia, however, markedly reduced cytokine levels, attenuated tissue injury, and improved survival. CONCLUSIONS: AM/AMBP-1 may be a novel treatment to attenuate the reperfusion injury after gut ischemia.  相似文献

For the last decades, the latissimus dorsi skin-muscle flap has contributed to the efficient reconstruction of the loss of skin cover (especially in breast surgery) and in long-distance tissue defects. Unfortunately, the nonuse of such an important muscle as the latissimus dorsi for the patient, as well as the resulting thickness of the flap after reconstruction, has turned it into a second choice flap. However, this flap is still indicated in the reconstruction of areas which need a great amount of cutaneous and muscular tissue. The appearance of the perforator flaps and, specifically, thoracodorsal artery perforator (TDAP) flap, has meant a radical change in relation to lower morbidity of the donor site, thus highly ranking the use of these flaps in the reconstruction for similar defects. The aim of this publication is to present our experience with the pedicled TDAP flap in a series of 17 different cases. Of those, there were 14 cases of mammary reconstruction after sparing surgery, 2 cases of axillary reconstruction following severe recurrent hidradenitis, and a case of extensive substance loss in a patient's upper limb following a severe crush injury.  相似文献

Aim The aim of the study was to analyze the short‐term and long‐term outcomes of nonagenarians treated for colorectal cancer. Method A retrospective analysis was performed of 74 patients, ≥ 90 years of age, diagnosed with colorectal cancer during the period 1986–2009. Comorbidity, American Society of Anesthesiology (ASA) grade, symptoms, diagnosis, treatment, mortality, morbidity and survival were analyzed. Results Of the 74 patients, 48 (65%) were women. Twenty‐two patients were classified as ASA grade I–II, 26 as ASA grade III and 26 as ASA grade IV–V. Thirty‐one (42%) had intestinal obstruction at the time of diagnosis. Twenty‐two (30%) patients were diagnosed during the period 1986–2000 and 52 (70%) were diagnosed between 2001 and 2009. Forty‐four (59%) patients underwent surgery, of whom 19 (49%) were treated as an emergency. Eleven (25%) patients died postoperatively, with mortality rates of 12% (3/25) for elective surgery and 42% (8/19) for emergency surgery. Surgical mortality for ASA grade I and grade II patients was 5% (1/20) and their 5‐year survival rate (postoperative mortality excluded) was 44%, whereas 5‐year survival for ASA grade III patients who underwent surgery was 12.5% and surgical mortality was 25% (4/16). There were no survivors beyond 36 months among patients who did not receive surgery. Conclusion Our results indicate that elective and emergency colorectal surgery can be performed with acceptable rates of mortality and morbidity on nonagenarian patients in good general condition with low perioperative risk. The 5‐year survival rate was related to ASA grade and to the use of surgery.  相似文献

Epidermoid cysts of the testis are rare in children (3% of all the testicular tumors). Bilateral appearance has only been described in the pediatric age in 2 cases and none associated to Klinefelter's syndrome. We present, for our knowledge, the first case of bilateral epidermoid testicular cyst associated to klinefelter's syndrome in a boy, highlighting its management and therapeutic approach. We analyze the different kinds of treatment.  相似文献

Bilateral symptomatic knee arthritis is a common clinical problem. There are conflicting opinions as to the advisability of simultaneous sequential bilateral total knee replacement. Complication rates of primary unilateral knee replacement are well documented and there are several small series that compare the two techniques. The objective of this study was to identify the complication rate of simultaneous sequential bilateral total knee replacement in a large patient population. Over a 13-year period, 604 primary bilateral sequential simultaneous total knee replacements (1208 knees) were performed. Office notes and hospital charts were retrospectively reviewed to obtain age, sex, diagnosis, knee alignment, associated comorbidities, operative protocol, transfusions, and complications. The study results showed 5.1% local and 15.3% systemic complications and 0.7% mortality rate (none in the past 9 years). With appropriate patient selection and operative technique, patients who present with bilateral symptomatic knee arthritis can enjoy the benefits of simultaneous sequential bilateral total knee replacement without increasing their risks of complications.  相似文献
