Near-Infrared Fluorescence with Indocyanine Green to Assess Bone Perfusion: A Systematic Review.

Adequate perfusion of a bone flap is essential for successful reconstruction of osseous defects. Unfortunately, complications related to inadequate bone perfusion are common. Near-infrared fluorescence (NIRF) imaging enables intraoperative visualization of perfusion.

Long-term outcomes of implant-based dental rehabilitation in head and neck cancer patients after reconstruction with the free vascularized fibula flap.

The study aimed at evaluating, comprehensively, implant-based dental rehabilitation in head and neck cancer patients after maxillofacial reconstruction with a vascularized free fibula flap (FFF). Data were obtained by retrospectively reviewing the medical records of patients treated in Amsterdam UMC-VU Medical Center. Dental implant survival and implant success according to the Albrektsson criteria were analyzed.

Accuracy of Computer-Assisted Surgery in Maxillary Reconstruction: A Systematic Review.

Computer-assisted surgery (CAS) in maxillary reconstruction has proven its value regarding more predictable postoperative results. However, the accuracy evaluation methods differ between studies, and no meta-analysis has been performed yet. A systematic review was performed in the PubMed, Embase, and Cochrane Library databases, using a Patient, Intervention, Comparison and Outcome (PICO) method: (P) patients in need of maxillary reconstruction using free osteocutaneous tissue transfer, (I) reconstructed according to a virtual plan in CAS software, (C) compared to the actual postoperative result, and (O) postoperatively measured by a quantitative accuracy assessment) search strategy, and was reported according to the PRISMA statement.

The Baker Classification for Capsular Contracture in Breast Implant Surgery Is Unreliable as a Diagnostic Tool.

Background: Breast implants are frequently used in cosmetic and reconstructive breast surgery. Capsular contracture, the most common long-term complication, is usually graded using the Baker classification. Despite its widespread use, the reliability of the Baker classification has never been established.

Collaboration Around Rare Bone Diseases Leads to the Unique Organizational Incentive of the Amsterdam Bone Center.

In the field of rare bone diseases in particular, a broad care team of specialists embedded in multidisciplinary clinical and research environment is essential to generate new therapeutic solutions and approaches to care. Collaboration among clinical and research departments within a University Medical Center is often difficult to establish, and may be hindered by competition and non-equivalent cooperation inherent in a hierarchical structure. Here we describe the "collaborative organizational model" of the Amsterdam Bone Center (ABC), which emerged from and benefited the rare bone disease team.

The Effectiveness of Burn Scar Contracture Release Surgery in Low- and Middle-income Countries.

Unlabelled: Worldwide, many scar contracture release surgeries are performed to improve range of motion (ROM) after a burn injury. There is a particular need in low- and middle-income countries (LMICs) for such procedures. However, well-designed longitudinal studies on this topic are lacking globally.

A Postoperative Evaluation Guideline for Computer-Assisted Reconstruction of the Mandible.

Valid comparisons of postoperative accuracy results in computer-assisted reconstruction of the mandible are difficult due to heterogeneity in imaging modalities, mandibular defect classification, and evaluation methodologies between studies. This guideline uses a step-by-step approach guiding the process of imaging, classification of mandibular defects and volume assessment of three-dimensional (3D) models, after which a legitimized quantitative accuracy evaluation method can be performed between the postoperative clinical situation and the preoperative virtual plan. The condyles and the vertical and horizontal corners of the mandible are used as bony landmarks to define virtual lines in the computer-assisted surgery (CAS) software.

Combined Massive Allograft and Intramedullary Vascularized Fibula as the Primary Reconstruction Method for Segmental Bone Loss in the Lower Extremity: A Systematic Review and Meta-Analysis.

Background: Reconstruction of segmental bone loss due to malignancy, infection, or trauma is a challenge for the reconstructive surgeon. The combination of a vascularized fibular flap with a cortical allograft provides a reliable reconstructive option in the lower extremity. In this systematic review, we describe the outcome of this technique for the treatment of segmental bone loss.

Impact of short-term reconstructive surgical missions: a systematic review.

Introduction: Short-term missions providing patients in low-income countries with reconstructive surgery are often criticised because evidence of their value is lacking. This study aims to assess the effectiveness of short-term reconstructive surgical missions in low-income and middle-income countries.

Methods: A systematic review was conducted according to PRISMA guidelines.

Accuracy of computer-assisted surgery in mandibular reconstruction: A postoperative evaluation guideline.

Comparing accuracy results for mandibular reconstructions using computer-assisted surgery (CAS) is limited due to heterogeneity in image acquisition, extent of mandibular resection, and evaluation methodologies between studies. We propose a practical, feasible and reproducible guideline for standardizing evaluation methods to allow valid comparisons of postoperative results and facilitate meta-analyses in the future. It offers a guide to imaging, data comparison, volume assessment of 3-dimensional models, classification of defects, and it also contains a quantitative accuracy evaluation method.

Accuracy of computer-assisted surgery in mandibular reconstruction: A systematic review.

Computer-assisted surgery (CAS) for mandibular reconstruction was developed to improve conventional treatment methods. In the past years, many different software programs have entered the market, offering numerous approaches for preoperative planning and postoperative evaluation of the CAS process of mandibular reconstruction. In this systematic review, we reviewed planning and evaluation methods in studies that quantitatively assessed accuracy of mandibular reconstruction performed with CAS.

Quality of life and patient satisfaction after one-stage implant-based breast reconstruction with an acellular dermal matrix versus two-stage breast reconstruction (BRIOS): primary outcome of a randomised, controlled trial.

Background: There is increasing interest in the use of acellular dermal matrices (ADMs) in implant-based breast reconstruction (IBBR). Suggested advantages are that ADMs facilitate one-stage IBBR and improve aesthetic outcomes. We compared immediate one-stage ADM-assisted IBBR with two-stage IBBR (current standard of care).

Double flap phalloplasty in transgender men: Surgical technique and outcome of pedicled anterolateral thigh flap phalloplasty combined with radial forearm free flap urethral reconstruction.

Introduction: Radial forearm free flap (RFFF) tube-in-tube phalloplasty is the most performed phalloplasty technique worldwide. The conspicuous donor-site scar is a drawback for some transgender men. In search for techniques with less conspicuous donor-sites, we performed a series of one-stage pedicled anterolateral thigh flap (ALT) phalloplasties combined with RFFF urethral reconstruction.

Cosmetic Outcome Assessment following Breast-Conserving Therapy: A Comparison between BCCT.core Software and Panel Evaluation.

Purpose. Over recent decades, no consensus has yet been reached on the optimal approach to cosmetic evaluation following breast-conserving therapy (BCT). The present study compared the strengths and weaknesses of the BCCT.

The effect of flexor hallucis longus harvest on hallux function: a retrospective cross-sectional cohort study.

Background And Aim: Our aim was to evaluate the long-term morbidity of the hallux function after harvesting a free fibula flap. Special attention was given to the differences between patients who underwent the dissection of an osteo-cutaneous flap (without inclusion of the flexor hallucis longus (FHL) muscle) and patients who were treated with an osteo-myo-cutaneous (with inclusion of the FHL muscle).

Methods: During the period 1995-2009, 167 patients underwent an autologous mandible reconstruction using a free fibula flap.

A systematic review of oncoplastic breast-conserving surgery: current weaknesses and future prospects.

Objective: The primary objectives of this systematic review on oncoplastic breast surgery (OPBS) were to evaluate the oncological and cosmetic outcomes of OPBS. The secondary objectives were to assess morbidity, quality of life, and applied algorithms.

Background: Breast-conserving therapy (BCT) has become the standard of care, and survival is now excellent.

Ultrasound-guided breast-sparing surgery to improve cosmetic outcomes and quality of life. A prospective multicentre randomised controlled clinical trial comparing ultrasound-guided surgery to traditional palpation-guided surgery (COBALT trial).

Background: Breast-conserving surgery for breast cancer was developed as a method to preserve healthy breast tissue, thereby improving cosmetic outcomes. Thus far, the primary aim of breast-conserving surgery has been the achievement of tumour-free resection margins and prevention of local recurrence, whereas the cosmetic outcome has been considered less important. Large studies have reported poor cosmetic outcomes in 20-40% of patients after breast-conserving surgery, with the volume of the resected breast tissue being the major determinant.

Management of recurrent ameloblastoma of the jaws; a 40-year single institution experience.

Ameloblastoma is a histologically almost always benign odontogenic tumor with a high rate of recurrence if not removed completely. Therefore, radical surgery is the treatment of choice of a primary ameloblastoma. Of 18 patients with a recurrent ameloblastoma, previously treated by enucleation, radical surgery was deemed impossible in three because of the extent of the tumor or because of a poor general condition of the patient.

Internal thoracic vessels used as pedicle graft for anastomosis with vascularized bone graft to reconstruct C7-T3 spinal defects: a new technique.

Study Design: A report of 4 cases of primary bone tumors (3 cases) or infection (1 case) at the cervicothoracic junction treated with resection-reconstruction.

Objectives: To document a new technique using the internal thoracic vessels as recipient vessels for reconstruction of the cervicothoracic spine with free vascularized fibula grafts.

Summary Of Background Data: The cervicothoracic junction is a difficult region in reconstructive spinal surgery.

Low prevalence of (pre) malignant lesions in the breast and high prevalence in the ovary and Fallopian tube in women at hereditary high risk of breast and ovarian cancer.

To analyse the prevalence of (pre) malignant lesions occurring in breast and adnexal tissue at prophylactic surgery in women at hereditary high risk of breast and/or ovarian cancers. Tissue was obtained from 85 women who underwent prophylactic bilateral salpingo-oophorectomy (pBSO) and from 59 women who underwent prophylactic mastectomy (pM). Control tissue samples were obtained from women undergoing breast reduction surgery (N = 99) or adnexal surgery for benign reasons (N = 72).
