    目的:由于全身毒性和血脑屏障(BBB)通透性的限制,全身治疗胶质母细胞瘤(GBM)的疗效仍然有限。颞顶筋膜瓣(TPFFs)和血管化的颅周皮瓣(PCF)不受血脑屏障(BBB)的限制,因为它们的血管供应来自颈外动脉的分支。血管化TPFF或PCF沿着GBM切除腔的转位可将不受BBB限制的自体组织带到肿瘤床微环境附近。允许由外部循环供给的血管通道向内生长,并提供一种绕过血脑屏障的机制。此外,血管化皮瓣中的循环免疫细胞可以更好地接触肿瘤微环境中的肿瘤相关抗原(TAA)。我们进行了一项首次人体I期试验,评估了新诊断的GBM患者的自体TPFF/PCF内衬切除腔的安全性。
    方法:12名患者接受了安全,新诊断GBM的最大手术切除,然后是带蒂的切除腔内衬,自体TPFF或PCF。通过监测不良事件评估安全性。疗效的次要分析被检查为经历无进展疾病(PFS)的患者比例,如神经肿瘤学(RANO)标准和总生存期(OS)中的反应评估所指示的。该研究能够根据这些早期结果确定是否需要进行II期研究。对于这个分析,在最后一次随访时仍存活且未进展的受试者被视为审查,在最后一次随访时仍存活的所有存活患者被视为总生存期审查.为简单起见,我们假设6个月时70%的PFS率被认为是一个令人鼓舞的反应,并为进一步调查该手术提供了依据.
    结果:纳入患者的中位年龄为57岁(范围46-69岁)。所有患者均为异柠檬酸脱氢酶(IDH)野生型。平均肿瘤体积为56.6cm3(范围14-145cm3)。在所有患者中,所有增强疾病的切除均被视为总切除(GTR)。3例患者出现III级或以上不良事件。术后即刻未发生IV级或V级严重不良事件,包括癫痫发作。感染,中风,或者肿瘤沿着皮瓣生长。仅在4例(33%)患者中发现了原始肿瘤部位的疾病进展(中位数为23个月,范围8-25个月),其中3人接受了再次手术。在重复手术中对那些植入的皮瓣和肿瘤床活检的组织病理学分析显示,移植的皮瓣内有强大的免疫浸润。重要的是,没有患者表现出肿瘤浸润到植入的皮瓣中的证据。在这份手稿准备的时候,只有4/12(33%)的患者死亡。基于上述统计学考虑,并且包括所有12名患者10/12(83.3%)具有6个月PFS。中位PFS为9.10个月,OS为17.6个月。4/12(33%)的患者存活超过两年,我们目前存活时间最长的患者存活时间为60个月。
    结论:这项初步研究表明,沿着GBM切除腔插入带蒂自体TPFF/PCF是安全可行的。基于6个月PFS和OS的令人鼓舞的响应率,有必要进行更大的第二阶段研究来评估和重现安全性,可行性,和功效。前瞻性注册试验的试验注册编号和注册日期:ClinicalTrials.govIDNCT03630289,日期:08/02/2018。
    OBJECTIVE: The efficacy of systemic therapies for glioblastoma (GBM) remains limited due to the constraints of systemic toxicity and blood-brain barrier (BBB) permeability. Temporoparietal fascial flaps (TPFFs) and vascularized peri cranial flaps (PCF) are not restricted by the blood-brain barrier (BBB), as they derive their vascular supply from branches of the external carotid artery. Transposition of a vascularized TPFF or PCF along a GBM resection cavity may bring autologous tissue not restricted by the BBB in close vicinity to the tumor bed microenvironment, permit ingrowth of vascular channels fed by the external circulation, and offer a mechanism of bypassing the BBB. In addition, circulating immune cells in the vascularized flap may have better access to tumor-associated antigens (TAA) within the tumor microenvironment. We conducted a first-in-human Phase I trial assessing the safety of lining the resection cavity with autologous TPFF/PCF of newly diagnosed patients with GBM.
    METHODS: 12 patients underwent safe, maximal surgical resection of newly diagnosed GBMs, followed by lining of the resection cavity with a pedicled, autologous TPFF or PCF. Safety was assessed by monitoring adverse events. Secondary analysis of efficacy was examined as the proportion of patients experiencing progression-free disease (PFS) as indicated by response assessment in neuro-oncology (RANO) criteria and overall survival (OS). The study was powered to determine whether a Phase II study was warranted based on these early results. For this analysis, subjects who were alive and had not progressed as of the date of the last follow-up were considered censored and all living patients who were alive as of the date of last follow-up were considered censored for overall survival. For simplicity, we assumed that a 70% PFS rate at 6 months would be considered an encouraging response and would make an argument for further investigation of the procedure.
    RESULTS: Median age of included patients was 57 years (range 46-69 years). All patients were Isocitrate dehydrogenase (IDH) wildtype. Average tumor volume was 56.6 cm3 (range 14-145 cm3). Resection was qualified as gross total resection (GTR) of all of the enhancing diseases in all patients. Grade III or above adverse events were encountered in 3 patients. No Grade IV or V serious adverse events occurred in the immediate post-operative period including seizure, infection, stroke, or tumor growing along the flap. Disease progression at the site of the original tumor was identified in only 4 (33%) patients (median 23 months, range 8-25 months), 3 of whom underwent re-operation. Histopathological analyses of those implanted flaps and tumor bed biopsy at repeat surgery demonstrated robust immune infiltrates within the transplanted flap. Importantly, no patient demonstrated evidence of tumor infiltration into the implanted flap. At the time of this manuscript preparation, only 4/12 (33%) of patients have died. Based on the statistical considerations above and including all 12 patients 10/12 (83.3%) had 6-month PFS. The median PFS was 9.10 months, and the OS was 17.6 months. 4/12 (33%) of patients have been alive for more than two years and our longest surviving patient currently is alive at 60 months.
    CONCLUSIONS: This pilot study suggests that insertion of pedicled autologous TPFF/PCF along a GBM resection cavity is safe and feasible. Based on the encouraging response rate in 6-month PFS and OS, larger phase II studies are warranted to assess and reproduce safety, feasibility, and efficacy. TRIAL REGISTRATION NUMBER AND DATE OF REGISTRATION FOR PROSPECTIVELY REGISTERED TRIALS: ClinicalTrials.gov ID NCT03630289, dated: 08/02/2018.

    人工耳蜗植入手术在印度变得越来越普遍,导致耳蜗植入物暴露等并发症的增加。为了解决这个问题,我们提出了一种新技术,该技术包括使用颞顶筋膜瓣(TPFF)和皮瓣进行单切口双覆盖,以持久覆盖暴露的人工耳蜗植入物。材料与方法2019年12月至2022年12月,对接受双皮瓣手术的患者进行了回顾性研究。结果平均缺损尺寸为2×2cm,平均住院时间为10天。14个皮瓣主要闭合,而两个需要移植皮肤以关闭供体部位。在出院时,所有伤口均显示成功愈合,耳蜗植入装置部位的皮肤覆盖完整。平均随访12个月,在此期间,两名患者有供体部位瘢痕脱发,而其他人有足够的头发生长掩盖疤痕。所有患者始终使用人工耳蜗。结论单切口,双盖TPFF+皮瓣技术为管理暴露的人工耳蜗植入物提供了可靠和创新的解决方案。随着成功的植入物抢救和良好的术后结果,这种方法证明了TPFF的多功能性和可靠性,是修复外科医师处理人工耳蜗并发症的绝佳选择.
    Cochlear implant surgeries have become increasingly common in India, leading to a rise in complications such as cochlear implant exposure. To address this issue, we present a novel technique involving a single incision dual cover using the temporoparietal fascial flap (TPFF) and skin flap to give durable cover for exposed cochlear implants. Materials and Methods  A retrospective study was conducted between December 2019 and December 2022 on patients who underwent the dual flap procedure for exposed cochlear implants. Results  The average defect size was 2 × 2 cm, and the average length of hospital stay was 10 days. Fourteen skin flaps were closed primarily, while two required skin grafting for donor site closure. At the time of discharge, all wounds showed successful healing with intact skin coverage over the cochlear implant device site. The average follow-up period was 12 months, during which two patients had donor site scar alopecia, while others had adequate hair growth masking the scar. All patients consistently used their cochlear implants. Conclusion  Our single-incision, dual cover TPFF + skin flap technique offers a reliable and innovative solution for managing exposed cochlear implants. With successful implant salvage and favorable postoperative outcomes, this approach demonstrates the versatility and reliability of the TPFF as an excellent option for reconstructive surgeons dealing with cochlear implant complications.

    多形性胶质母细胞瘤(GBM)患者继续遭受不良预后。血脑屏障(BBB)是治疗的障碍之一,形成一个屏障,降低中枢神经系统中化疗剂的生物利用度。以前,在我们机构进行的一项试验中,引入了位于切除腔内的血管化颞顶筋膜头皮皮瓣(TPFF),在初次切除后试图绕过BBB的新诊断的GBM患者中。在本文中,我们报道了一项新技术,该技术可在再次切除后绕过血脑屏障,并有可能通过免疫系统监测肿瘤抗原.该研究旨在评估GBM再切除后进行颅骨移位和自体网膜血运重建的可行性。由神经外科医生组成的团队将腹腔镜下收获的网膜游离皮瓣转移到切除腔中,耳鼻喉科医师,和普通外科医生。这是作为一个单一中心的一部分,单臂,开放标签,第一阶段研究。2例患者在其血管化椎弓根腹腔镜下采集自体腹部大网膜组织,换作自由皮瓣,使用颈外动脉进行血运重建,小心地放在肿瘤切除腔内.患者术后恢复到基线活动表现良好。移植物活力通过脑血管造影证实。腹腔镜手术切除的网膜颅移位,血管化皮瓣,入再次切除的GBM患者的腔内在短期内是可行且安全的。需要进一步的研究来确定这种技术是否可以改善这些患者的无进展生存期和总生存期。
    Glioblastoma multiforme (GBM) patients continue to suffer a poor prognosis. The blood brain barrier (BBB) comprises one of the obstacles for therapy, creating a barrier that decreases the bioavailability of chemotherapeutic agents in the central nervous system. Previously, a vascularized temporoparietal fascial scalp flap (TPFF) lining the resection cavity was introduced in a trial conducted in our institution, in newly-diagnosed GBM patients in an attempt to bypass the BBB after initial resection. In this paper, we report on a new technique to bypass the BBB after re-resection and potentially to allow tumor antigens to be surveilled by the immune system. The study aims to assess the feasibility of performing a cranial transposition and revascularization of autologous omentum after re-resection of GBM. Laparoscopically harvested omental free flap was transposed to the resection cavity by a team consisting of neurosurgeons, otolaryngologists, and general surgeons. This was done as part of a single center, single arm, open-label, phase I study. Autologous abdominal omental tissue was harvested laparoscopically on its vascularized pedicle in 2 patients, transposed as a free flap, revascularized using external carotid artery, and carefully laid into the tumor resection cavity. Patients did well postoperatively returning to baseline activities. Graft viability was confirmed by cerebral angiogram. Omental cranial transposition of a laparoscopically harvested, vascularized flap, into the cavity of re-resected GBM patients is feasible and safe in the short term. Further studies are needed to ascertain whether such technique can improve progression free survival and overall survival in these patients.

    目的:并发症,包括框架暴露,感染,重建耳廓变形,可能发生在耳廓重建后。然而,关于使用自体肋软骨进行耳廓重建术后效果不理想的病例的手术方法的报道不足.在这里,我们总结了在我们部门接受了5年耳廓重建术的患者耳部形态不良的再治疗病例,并讨论了其他技术。
    方法:2014年9月至2019年9月,24例形态差患者的24耳,不令人满意的宏观特征和解剖结构,耳廓重建手术后局部修复效果不理想。患者分为以下三组:1型(9耳),在重建的耳朵后面的乳突区域具有完整且足够的无毛皮肤;2型(7耳),完好无损,但不够,在重建的耳朵后面的乳突区域的无毛皮肤;和类型3(8耳),重建耳朵后面的乳突区域无毛皮肤,皮肤完整性受损。
    结果:22例(91.6%)患者成功完成手术治疗,恢复良好;1例伤口延迟愈合,1例术后3个月切口处出现肥厚性瘢痕。所有患者均随访0.5-4(平均,2.8)年。翻修后重建耳的宏观结构稳定,在形态和结构方面均有明显改善。
    结论:耳廓重建术后预后不理想的患者,适当的翻修手术技术应考虑重建耳的局部软组织条件,以获得满意的效果。
    OBJECTIVE: Complications, including framework exposure, infections, and reconstructed auricle deformation, may occur after auricular reconstruction. However, reports on surgical methods for cases with unsatisfactory outcomes after auricular reconstruction using an autologous costal cartilage are insufficient. Herein, we summarized retreatment casesfor poor ear morphology in patients who had undergone auricular reconstruction in our department for 5 years and discussed other techniques.
    METHODS: Between September 2014 and September 2019, 24 ears of 24 patients with poor morphology, unsatisfactory macroscopic characteristics and anatomical structures, and unsatisfactory outcomes of local repair after auricular reconstructive surgery were treated. Patients were divided into the following three groups: type 1 (9 ears), with intact and sufficient hairless skin in the mastoid region behind the reconstructed ear; type 2 (7 ears), with intact, but insufficient, hairless skin in the mastoid region behind the reconstructed ear; and type 3 (8 ears), with hairless skin in the mastoid region behind the reconstructed ear with impaired skin integrity.
    RESULTS: Twenty-two (91.6%) patients successfully completed the surgical treatment and recovered well; one experienced delayed wound healing and another developed hypertrophic scarring at the incision site at 3 months postoperatively. All patients were followed for 0.5-4 (mean, 2.8) years. The macrostructure of the reconstructed ear post-revision was stable and significantly improved in terms of morphology and structure.
    CONCLUSIONS: In patients with unsatisfactory outcomes after auricular reconstruction, the appropriate technique for the revision surgery should consider the local soft tissue conditions of the reconstructed ear to obtain satisfactory results.

    BACKGROUND: Soft tissue reconstruction of the hand and distal upper extremity is challenging to preserve the function of the hand as good as possible. Therefore, a thin flap has been shown to be useful. In this retrospective study, we aimed to show the use of the free temporoparietal fascial flap in soft tissue reconstruction of the hand and distal upper extremity.
    METHODS: We analysed the outcome of free temporoparietal fascial flaps that were used between the years 2007and 2016 at our institution. Major and minor complications, defect location and donor site morbidity were the main fields of interest.
    RESULTS: 14 patients received a free temporoparietal fascial flap for soft tissue reconstruction of the distal upper extremity. Minor complications were noted in three patients and major complications in two patients. Total flap necrosis occurred in one patient.
    CONCLUSIONS: The free temporoparietal fascial flap is a useful tool in reconstructive surgery of the hand and the distal upper extremity with a low donor site morbidity and moderate rates of major and minor complications.

    With an increase in the number of cochlear implant surgeries there is bound to be an increase in the number of complications. A dreaded problem in any implant procedure is the implant exposure and infection. Explantation of the implant leads to an unpleasant situation to the patient and the surgeon owing to the high cost of the device. There are reports in the literature favouring the mandatory relocation or removal of the infected implants. On the other hand, there are convincing reports of implant salvage using skin, muscle or fascial flaps. In this paper we have analysed a series of cases referred to us from the departments of E.N.T for the management of implant exposure/infection. We have also reviewed similar case series reported in the literature. From 2014 to 2017 we operated six cases of exposed cochlear implant. We salvaged the implant in five cases, where we could do two layer coverage consisting of the inner temporoparietal fascial flap and outer scalp skin flap. In one case where the temporoparietal fascial flap could not be done as superficial temporal vessels were found to be injured in the previous surgery, the implant was removed due to persistent infection. All these cases were administered appropriate antibiotics for a minimum period of 3 weeks. Early double layer closure with inner temporoparietal fascial flap and outer scalp rotation flap coupled with appropriate antibiotics can salvage an infected, exposed implant.

    Reconstruction of combined skin and tendon loss in an injury of the dorsum of the hand is a challenging problem because it is required to achieve adequate excursion of the tendon. We herein report our case of extensor tendon repair for a dorsal hand injury using a rolled deep temporal fascial (DTF) graft and a free temporoparietal fascial flap. The patient regained satisfactory hand function with minimal donor site morbidity. DTF utilization as tendon grafts spares another incision for tendon grafting. Furthermore, one can integrate all the donor sites into the temporal region by choosing the scalp as a donor site for skin grafting. Patients can benefit from this procedure, which provides a functional reconstruction of the hand and leaves only inconspicuous donor site scars.

    The success of expanded endoscopic endonasal approaches (EEAs) to the anterior skull base, sellar, and parasellar regions has been greatly aided by the advancement in reconstructive techniques. In particular, the pedicled vascularized flaps have been developed and effectively cover skull base defects of varying sizes with a significant reduction in postoperative CSF leaks. There are two aims to this review: (1) We will provide our current, simplified reconstruction algorithm. (2) We will describe, in detail, the relevant anatomy, indications/contraindications, and surgical technique, with a particular emphasis on the nasoseptal flap (NSF). The inferior turbinate flap (ITF), middle turbinate flap (MTF), pericranial flap (PCF), and temporoparietal fascial flap (TPFF) will also be described. The NSF should be the primary option for reconstruction of majority of skull base defects following endonasal endoscopic surgery. In general, for the planum, cribriform, and upper two-thirds of the clivus, the NSF is ideal. For the lower-third of the clivus, the NSF may not be adequate and may require additional reconstructive options. Although limited in reach or more technically challenging, these reconstructive flaps should still be considered and kept in the surgical algorithm.

    BACKGROUND: PCF is the most common major complication after salvage total laryngectomy (TL), especially for previously irradiated patients with laryngeal or hypopharyngeal cancer.
    RESULTS: A 65-year-old woman presented with recurrent bilateral supraglottic SCC requiring salvage TL 5.5years after initial T1N0M0 epiglottic SCC resection. Her post-operative course was complicated by PCF development one month post-operatively and surgical fistula closure was delayed for adjuvant chemoradiotherapy. The fistula persisted despite local wound therapy, several primary closures, pectoralis flap reconstruction with multiple revisions, and extensive hyperbaric oxygen treatments. Given her prior history, she underwent a staged right temporoparietal fascial flap reconstruction for persistent complex fistula, with second-stage flap takedown and complete inset of the TPFF skin island into the PCF.
    CONCLUSIONS: This case demonstrates the utility of staged TPFF in complex PCF repair, with minimal morbidity, especially in a patient with prior irradiation and flap use that complicates tissue availability.

    OBJECTIVE: This article introduces a classification scheme for extensive traumatic anterior skull base fracture to help stratify surgical treatment options. The authors describe their multilayer repair technique for cerebrospinal fluid (CSF) leak resulting from extensive anterior skull base fracture using a combination of laterally pediculated temporalis fascial-pericranial, nasoseptal-pericranial, and anterior pericranial flaps.
    METHODS: Retrospective chart review identified patients treated surgically between January 2004 and May 2014 for anterior skull base fractures with CSF fistulas. All patients were treated with bifrontal craniotomy and received pedicled tissue flaps. Cases were classified according to the extent of fracture: Class I (frontal bone/sinus involvement only); Class II (extent of involvement to ethmoid cribriform plate); and Class III (extent of involvement to sphenoid bone/sinus). Surgical repair techniques were tailored to the types of fractures. Patients were assessed for CSF leak at follow-up. The Fisher exact test was applied to investigate whether the repair techniques were associated with persistent postoperative CSF leak.
    RESULTS: Forty-three patients were identified in this series. Thirty-seven (86%) were male. The patients\' mean age was 33 years (range 11-79 years). The mean overall length of follow-up was 14 months (range 5-45 months). Six fractures were classified as Class I, 8 as Class II, and 29 as Class III. The anterior pericranial flap alone was used in 33 patients (77%). Multiple flaps were used in 10 patients (3 salvage) (28%)--1 with Class II and 9 with Class III fractures. Five (17%) of the 30 patients with Class II or III fractures who received only a single anterior pericranial flap had persistent CSF leak (p < 0.31). No CSF leak was found in patients who received multiple flaps. Although postoperative CSF leak occurred only in high-grade fractures with single anterior flap repair, this finding was not significant.
    CONCLUSIONS: Extensive anterior skull base fractures often require aggressive treatment to provide the greatest long-term functional and cosmetic benefits. Several vascularized tissue flaps can be used, either alone or in combination. Vascularized flaps are an ideal substrate for cranial base repair. Dual and triple flap techniques that combine the use of various anterior, lateral, and nasoseptal flaps allow for a comprehensive arsenal in multilayered skull base repair and salvage therapy for extensive and severe fractures.
