Radial free flap

  • 文章类型: Journal Article
    背景:radial前臂皮瓣(RFF)是重建手术中最常用的皮瓣之一。传统上,厚皮移植(STSG)用于前臂的闭合。然而,全层植皮术(FTSG)已得到普及,取得了更满意的效果。该研究的目的是通过比较STSG和FTSG的功能和美学结果来确定最佳的RFF供体部位闭合技术。
    方法:查询PubMed和EMBASE数据库。只有比较并发症发生率的研究,包括STSG和FTSG之间的功能和美学结果。主要结果是移植物失败率。次要结果包括前臂/手腕的美学结果和功能。
    结果:本综述共纳入13项研究,共712例患者,平均年龄为60.7岁。总的来说,348例患者接受FTSG,377例接受STSG。平均随访14.7个月。FTSG的移植物失败率明显高于STSG(OR:2.79,95%CI1.38-5.65,p=0.004)。肌腱外露率(OR:0.83,p=0.65)和感染率(OR:1.37,p=0.42)差异无统计学意义。关于美学结果,根据观察者(SMD=-0.37,p=0.17)和患者(SMD=-0.016,p=0.93)评估,FTSG和STSG之间没有显着差异,分别。术后总体功能评估显示,两组的手和手臂功能均未严重受损。两组对疼痛的主观评价相似。
    结论:在RFF供体部位闭合中,与STSG相比,FTSG与更高的移植物衰竭风险相关,在美学效果上没有显著改善。
    BACKGROUND: The radial forearm flap (RFF) is one of the most commonly used flaps in reconstructive surgery. Split-thickness skin grafting (STSG) has traditionally been used for closure of the forearm. However, full-thickness skin grafting (FTSG) has gained in popularity to achieve more satisfactory results. The aim of the study is to identify the best RFF donor site closure technique by comparing the functional and aesthetic outcomes of STSG and FTSG.
    METHODS: PubMed and EMBASE databases were queried. Only studies comparing complications rate, functional and aesthetic outcomes between STSG and FTSG were included. The primary outcome was graft failure rate. Secondary outcomes included the aesthetic result and functionality of the forearm/wrist.
    RESULTS: A total of 13 studies were included in this review, accounting for a total of 712 patients with mean age of 60.7 years. Overall, 348 patients underwent FTSG and 377 underwent STSG. The mean follow-up was 14.7 months. The rate of graft failure in FTSG was significantly higher compared to STSG (OR: 2.79, 95 % CI 1.38-5.65, p = 0.004). There was no significant difference in rate of tendon exposure (OR: 0.83, p = 0.65) and infection (OR: 1.37, p = 0.42). Regarding the aesthetic outcome, no significant difference between FTSG and STSG based on observer (SMD = -0.37, p = 0.17) and patient (SMD = -0.016, p = 0.93) assessment, respectively. Overall postoperative functional assessment showed a not severely impaired hand and arm function in both groups. Subjective evaluation of pain was similar between groups.
    CONCLUSIONS: FTSG is associated with higher risk of graft failure than STSG in RFF donor site closure, without significant improvement in aesthetic results.

    背景:radial前臂游离皮瓣(RFFF)是重建一系列缺陷的不可或缺的工具,包括颅底.已经描述了RFFF椎弓根的几种选择,并且已经提出了咽旁通道(PC)作为一种选择并用于鼻咽缺损。然而,没有关于其用于重建前颅底缺损的报道。
    目的:描述使用RFFF和通过PC对椎弓根进行布线的前颅底缺损的游离组织重建技术。
    方法:使用说明性的临床病例和尸体解剖报告了使用RFFF重建前颅底缺损的相关神经血管标志和关键手术步骤。
    结果:我们介绍了一例70岁的男性患者,他接受了cT4N0鼻窦鳞状细胞癌的内镜转录型切除术,并留下了一个巨大的前颅底缺损,尽管有多次修复尝试,但仍然存在。利用RFFF来修复缺陷。该报告是对PC用于前颅底缺损的免费组织修复的临床用途的首次描述。
    结论:PC是重建前颅底缺损期间椎弓根的一种选择。当走廊按照这种情况进行准备时,从前颅底到颈血管的直接途径,同时最大限度地扩大椎弓根的范围和最大限度地减少扭结的风险。
    The radial forearm free flap (RFFF) is an indispensable tool for the reconstruction of a range of defects, including those of the skull base. Several options for routing of the RFFF pedicle have been described, and the parapharyngeal corridor (PC) has been proposed as an option and employed for a nasopharyngeal defect. However, there are no reports of its use for the reconstruction of anterior skull base defects. The objective of this study is to describe the technique for free tissue reconstruction of anterior skull base defects using the RFFF and routing of the pedicle via the PC.
    Relevant neurovascular landmarks and critical surgical steps for reconstruction of anterior skull base defects with an RFFF and routing of the pedicle via the PC are reported using an illustrative clinical case and cadaveric dissections.
    We present a case of a 70-year-old man who underwent endoscopic transcribriform resection of cT4N0 sinonasal squamous cell carcinoma and was left with a large anterior skull base defect that persisted despite several repair attempts. An RFFF was utilized to repair the defect. This report is the first description of the clinical use of the PC for free tissue repair of an anterior skull base defect.
    The PC is an option for routing the pedicle during the reconstruction of anterior skull base defects. When the corridor is prepared as described in this case, a direct route exists from the anterior skull base to cervical vessels, simultaneously maximizing the reach of the pedicle and minimizing the risk of kinking.

    背景:眼球鳞状细胞癌的患病率较低,这是一种罕见的情况。有多种治疗策略的治疗,并取决于肿瘤的局部受累和扩展的程度,反过来,会对患者的预后产生影响。
    方法:我们介绍了一例患者,其左眼球白色视觉损害有大量进行性生长。活检显示结膜鳞状细胞癌,影像学检查显示眼眶侵犯cT4bN0cM0,因此需要手术治疗。手术以5毫米的宏观边缘进行。切除后,进行了径向游离皮瓣重建。放疗辅助治疗无并发症。六个月后,病人的生活质量有所改善,而且没有复发的证据.
    结论:结膜鳞状细胞癌的患病率较低。最重要的风险因素是暴露于紫外线。大多数源自结膜上皮内肿瘤。有化疗药物和眼或眼眶侵犯患者的局部治疗方案,摘除和摘除是选择的治疗方法。
    结论:结膜鳞状细胞癌是罕见的。局部晚期肿瘤的治疗是手术。使用径向游离皮瓣重建是考虑的重建策略之一,以及控制疾病所需的其他策略的知识对于确保最佳治疗非常重要。
    BACKGROUND: The prevalence of squamous cell carcinoma of the eyeball is low, and this is a rare condition. There are multiple therapeutic strategies for the treatment and depend on the degree of local involvement and extension of the tumor which, in turn, will have an impact on the patient\'s prognosis.
    METHODS: We present a case of a patient with a mass of progressive growth on the left eyeball whit vision damage. The biopsy showed a squamous cell carcinoma of the conjunctiva, and imaging studies showed orbital invasion cT4bN0cM0, so surgery was indicated. The surgery was done with macroscopic margins of 5 mm. After resection, a radial free flap reconstruction was performed. Adjuvant treatment with radiotherapy was performed without complications. After six months, the patient manifested an improvement in his quality of life, and there is no evidence of relapse.
    CONCLUSIONS: The prevalence of squamous cell carcinoma of the conjunctiva is low. The most important risk factor is exposure to UV rays. Most are derived from conjunctival intraepithelial neoplasms. There are topical management protocols with chemotherapeutic agents and in patients with ocular or orbital invasion, enucleation and exanteration are the treatments of choice.
    CONCLUSIONS: The squamous cell carcinoma of the conjunctive is rare. The management in the locally advanced tumors is surgical. The use of a radial free flap reconstruction is one of the reconstructive strategies to take into account, and the knowledge of additional strategies required to control the disease is important to ensure an optimal treatment.

    The radial forearm free flap (RFFF) and ulnar forearm free flap (UFFF) are used in head and neck reconstruction because they provide a thin and pliable skin paddle as well as a long vascular pedicle. However, in spite of several studies showing the safety of the UFFF, the RFFF is more popular among reconstructive surgeons based on concerns about hand ischaemia. A prospective study was designed in which 10 UFFF and 11 RFFF surgeries were performed in 20 patients undergoing oral cavity reconstruction between January 2017 and July 2018. Hand vascular parameters were evaluated preoperatively and postoperatively using Doppler ultrasound and plethysmography. The preoperative and postoperative diameters of the radial and ulnar arteries, and the flow velocities through the remainder of the forearm artery were measured preoperatively and at 3 months postoperative. Additionally, a comparison was performed between the preoperative and postoperative fingertip perfusion values according to impedance plethysmography. The preoperative mean diameter of the radial artery (2.89±0.47mm) was significantly greater than that of the ulnar artery (2.35±0.48mm) at the level of the wrist; however, 3 months after the surgery, the mean diameters of the two arteries did not differ significantly. There were no differences in digital perfusion when a UFFF was used compared with an RFFF.

    Abstarct Background: Due to the high rate of donor site complications the Radial Forearm Flap (RFF) has lost ground in favor of the Antero-lateral tight flap (ALT) and other flaps. We have designed a reconstruction algorithm for reconstruction of its donor site. The goal of this study was to retrospectively evaluate the impact of this algorithm on RFF donor site complication rates.
    METHODS: The authors analyzed retrospectively 31 patients who underwent free radial forearm flap reconstruction between November 2009 and May 2013. Donor site complications were compared with data from patients treated before introdutction of the algorithm. Within the group were compared patients in which the flap was harvested suprafascial with those in which the flap was harvested as subfascial.
    RESULTS: Before application of the algorithm, there was a 23.3% complication rate at the RFF donor site, in our experience. After introduction of the algorithm, complication rate has dropped to 3.2%, consisting in a partial skin graft necrosis treated by local wound-care and healed without further intervention.
    CONCLUSIONS: Application of the algorithm described has led to a significant reduction in RFF donor site complication rates. This demonstrates that if flap donor sites are analyzed and tailor treated in the same way as primary defects are, instead of being given secondary importance and just grafted, outcomes improve.
