ObjectivesMeshes/matrices are commonly used in immediate breast reconstruction. There are few studies comparing biological and synthetic meshes and it is unknown what type of mesh gives the best long-term results. The aim of this study was to compare long-term health-related quality of life (HrQoL) and patient satisfaction in implant-based immediate breast reconstruction with a biological mesh (Surgisis®) with that of patients reconstructed with a synthetic mesh (TIGR ® Matrix Surgical Mesh).Material and methodsBoth cohorts were prospectively included and consecutively operated. Clinical data was collected. HrQoL was evaluated with EuroQoL-5 dimension – 3 levels questionnaire (EQ-5D-3L) and the Hospital Anxiety and Depression Scale (HADS) and the Breast-Q.Results and conclusionSeventy-one patients were operated on in the biological group and 49 in the synthetic group. The response rates were 75 and 84 per cent, respectively. Mean follow-up time was 74 months and 23 months, respectively. There were no statistical differences in satisfaction and quality of life between the two groups. Complications and radiation seem to lead to a lower satisfaction. Our findings could indicate that biological and synthetic meshes give an equal long-term result as regards patients’ perceived quality of life. 相似文献

The syndactyly repairs of 11 hands in seven patients (average age 20.4) who had simple complete syndactyly between the third and fourth fingers were done by the use of tissue expanders in order to obtain adequate skin closure. At the first stage, a wedge type, 7 cc tissue expander was placed beneath the dorsal skin of the syndactylous digits via a vertical dorsal hand incision under local anesthesia. Inflation was begun on the 15th postoperative day. After the inflation period (average 32 days), syndactyly repair similar to the Littler technique was performed using axillary block anesthesia. During the expansion period one tissue expander became exposed and this hand was repaired by the classical skin grafting technique. In the remaining ten hands the expanded dorsal skin ensured skin closure of the digits and web reconstruction without any need for skin grafting. No complications were encountered during the postoperative period. Active and passive abduction angles, tip-to-tip length, active range of motion of the digits, and two point discrimination tests were done at follow-up (average six months). The web appearances were normal in all patients. Active abduction angles and active range of motion of the digits was always normal at the third postoperative month. Two point discrimination was 8.7 mm on the interdigital sides of the digits and there was no tip-to-tip length differences of the digits. No contractures were seen.Presented at the International Congress of Surgery of the Hand and Upper Extremity, Izmir, Turkey, September 25, 1994. 相似文献

目的研究软组织扩张术患者扩张囊内、外的细菌数量及种类,为临床上防治扩张术感染提供依据。方法连续采集33例扩张术患者的51枚扩张囊内、外的液体标本,进行常规细菌培养和药敏试验,并将其结果进行统计学处理,采用Y0检验和Kappa检验。结果扩张囊内、外的细菌检出率分别为3.92%(2枚)、17.65%(9枚),囊外阳性率显著高于囊内(P〈0.05),囊内、外细菌的检出结果一致性较差(Kappa〈0.4)。细菌种类为金黄色葡萄球菌和凝固酶阴性葡萄球菌,对庆大霉素、去甲万古霉素、环丙沙星均敏感。33例患者(51枚)中,有10例患者(10枚)检出细菌,仅有1例患者(1枚)出现临床感染症状,致病菌为金黄色葡萄球菌。结论严格消毒后进行穿刺注水导致感染的几率很低,而感染后的细菌培养和药敏试验是治疗的关键。 相似文献

Summary Traumatic defects of the auricle are quite common. The eventual success of the repair is considerably influenced by the initial treatment. The different parts of the auricle require different approaches. This paper presents our methods for repairing damage to the cartilaginous frame using autologous ear cartilage grafts, and local flaps from the mastoid region to cover soft tissue defects. 相似文献

目的探讨组织扩张器(TE)延长神经后神经长度、功能和组织学变化。方法TE以不同程度(8d共注水分别为2、4及8ml)及不同速度(分别于8、12及16d注水8ml)延长坐骨神经,对延长后神经进行电生理学、组织学检测,并进行组内比较。结果(1)神经延长后,其传导速度(NCV)、复合肌肉动作电位(CMAP)有一定程度降低,组织学有改变;(2)重度延长组(8ml组)改变比轻度延长组(2ml组)、中度延长组(4ml组)更为明显,快速延长组(8d组)比中速延长组(12d组)、慢速延长组(16d组)改变更为明显。结论(1)TE可有效地延长神经长度,同时神经伴有功能和组织学改变;(2)神经延长长度越长、速度越快,这些改变越明显。 相似文献

Perioperative infection is the most common and dreaded complication associated with tissue expander (TE) breast reconstruction. Historically, the expansion period was thought to be the time of greatest hazard to the implant. However, recent institutional observations suggest infectious complications occur prior to expansion. This investigation, therefore, was conducted to determine the timing of infectious complications associated with two‐stage TE breast reconstructions. Following IRB approval, a retrospective review of all consecutive two‐stage immediate TE breast reconstructions at a single institution from November 2007 to November 2011 was conducted. Reconstructions were then divided into two cohorts: those suffering infectious complications and those that did not. Infectious complications including minor cellulitis, major cellulitis, abscess drainage, and explantation were identified. Various operative and patient variables were evaluated in comparison. Eight hundred ninety immediate two‐stage TE breast reconstructions met inclusion criteria. Patients suffering infection were older (55.4 years versus 49.3 years; p < 0.001), and more likely to have therapeutic mastectomy (94% versus 61%; p < 0.0001), the use of acellular dermal matrix (ADM; 72.5% versus 54.9%; p = 0.001), and greater initial TE fill (448.6 mL versus 404.7 mL; p = 0.0078). The average time to developing of infectious symptoms was 29.6 days (range 9–142 days), with 94.6% (n = 87) of infections prior to the start of expansion. Perioperative infections in immediate two‐stage TE to implant breast reconstructions are significant and occur mostly prior to the start of expansion. Thus, challenging the conventional wisdom that instrumentation during expander filling as the primary cause of implant infections. Possible etiologic factors include greater age, therapeutic mastectomy versus prophylactic mastectomy, larger initial TE fill, and the use of ADM. 相似文献

目的探讨使用铸造式扩弓器非拔牙矫治安氏Ⅰ类错(?)伴轻中度牙列拥挤病例的临床疗效,为临床应用提供依据。方法选取32例安氏Ⅰ类错(?)畸形伴轻中度牙列拥挤病例。其中17例采用铸造式上颌扩弓配合固定矫治技术进行非拔牙正畸治疗(实验组);15例仅采取非拔牙的固定矫治(对照组)。分别在T1(正畸治疗前)、T2(正畸治疗结束)拍摄头颅侧位定位片并测量分析。结果头影测量分析显示两组间下颌平面角及前面高的增加无统计学差异(P>0.05)。对照组上前牙明显较扩弓组唇倾(P<0.05),下前牙唇倾量均有增加(扩弓组=4.05°,对照组=7.16°,P>0.05)。扩弓组上、下前牙突距(U1-NA和L1-NB)变化量更小(P<0.05)。两组间上颌磨牙垂直高度的变化无显著性差异。结论铸造式扩弓器在扩宽牙弓解除拥挤的同时,能有效地控制磨牙高度及面下1/3高度的变化。 相似文献
