Preoperative virtual surgical planning and the use of 3D-printed patient-specific models and cutting guides are increasingly being used in the reconstruction of mandibular defects with a free bone flap. This technology offers several advantages over conventional surgery, such as reduced operating time, reduced bone flap ischaemia time, and the ability to perform more complex and precise reconstructions. This review presents the evidence supporting 3D-assisted surgery for mandibular defect reconstruction and discusses the utilisation of commercial vendors versus in-house 3D-printing solutions.

Chronic fistulas are a dreaded complication to surgery. They are often persistent to treatment and involve several negative side effects and a significant reduction in quality of life. We present a case report of a 36-year-old male with a deep chronic fistula in the pelvis after pouch surgery.

Improving Visualization of Intramuscular Perforator Course: Augmented Reality Headsets for DIEP Flap Breast Reconstruction.

Background: Augmented reality (AR) technology, exemplified by devices such as the Microsoft HoloLens 2, has gained interest for its potential applications in preoperative guidance. This study explores the use of AR technology for perforator identification during deep inferior epigastric artery perforator (DIEP) flap breast reconstruction.

Methods: A case series of five patients where an AR device was used to identify perforators during DIEP flap breast reconstruction is presented.

Severe midface necrosis after liver failure induced fungal infection: A case report on the outcome after reconstruction.

Introduction: Reconstruction of the complex anatomy of the midface is challenging and requires meticulous preparation. Immunosuppression therapy increases patient susceptibility to infection and can compromise wound healing.

Presentation Of Case: A 22-year-old male presented with acute hepatic failure and underwent liver transplantation.

Knee-saving Amputation by Use of a Bipedicled Four-zone Deep Inferior Epigastric Artery Perforator Flap.

Degloving traumatic lower extremity injuries can lead to an above-knee amputation with decreased functional capacity compared with below-knee amputation. The unique properties of the deep inferior epigastric artery perforator flap providing a substantial amount of skin and subcutaneous tissue combined with reliability and low donor-site morbidity makes the flap ideal for coverage of below-knee amputation stumps when soft tissue is required. A bipedicled four-zone deep inferior epigastric artery perforator flap with a skin area of 13 × 33 cm was used as coverage of a degloved lower leg amputation stump, in a 27-year-old woman with a left-sided Gustillo type 3B comminute diaphyseal tibial fractur and major degloving injury.

Oncological results and morbidity following intended curative resection and free jejunal graft reconstruction of cervical esophageal cancer: a retrospective Danish consecutive cohort study.

Background: The role of surgery in treatment of locally advanced cervical esophageal cancer (CEC) remains debated. In the European and American treatment guidelines, definitive chemoradiotherapy (dCRT) is preferred over surgery, while in the Danish guidelines, the two treatment modalities are equally recommended. Surgical treatment of CEC is centralized at our center in Denmark.

Bone mineral density changes in a free vascularised fibular graft in the distal femoral bone after osteosarcoma in a 10-year-old boy: a 7-year follow-up.

A 10-year-old boy presented with continuous reports of pain located to the left knee. Imaging revealed a sclerotic process in the left distal femur, and biopsies were consistent with chondroblastic osteosarcoma. As part of standard treatment the patient underwent neoadjuvant chemotherapy followed by limb sparring surgery and adjuvant chemotherapy.

Remote ischemic preconditioning does not influence lectin pathway protein levels in head and neck cancer patients undergoing surgery.

Background: Cancer patients who undergo tumor removal, and reconstructive surgery by transfer of a free tissue flap, are at high risk of surgical site infection and ischemia-reperfusion injury. Complement activation through the lectin pathway (LP) may contribute to ischemia-reperfusion injury. Remote ischemic preconditioning (RIPC) is a recent experimental treatment targeting ischemia-reperfusion injury.

[Orthopaedic treatment of malignant bone tumours in children].

The treatment of malignant bone tumours in children has improved significantly over the past 50 years. Previously, the only curative treatment was amputation, but today the surgical treatment has changed towards limb salvage surgery. However, there is not consensus regarding choice of surgical procedure, and it is mainly based upon the surgeon's previous experience.

The generation of enlarged eroded pores upon existing intracortical canals is a major contributor to endocortical trabecularization.

The gradual conversion of cortical bone into trabecular bone on the endocortical surface contributes substantially to thinning of the cortical bone. The purpose of the present study was to characterize the intracortical canals (3D) and pores (2D) in human fibular bone, to identify the intracortical remodeling events leading to this endocortical trabecularization. The analysis was conducted in fibular diaphyseal bone specimens obtained from 20 patients (6 women and 14 men, age range 41-75 years).

Effect of remote ischemic preconditioning on hemostasis and fibrinolysis in head and neck cancer surgery: A randomized controlled trial.

Introduction: The aim of this randomized controlled trial was to investigate if remote ischemic preconditioning (RIPC) reduced platelet aggregation and increased fibrinolysis in cancer patients undergoing surgery and thereby reduced the risk of thrombosis.

Materials And Methods: Head and neck cancer patients undergoing tumor resection and microsurgical reconstruction were randomized 1:1 to RIPC or sham intervention. RIPC was administered intraoperatively with an inflatable tourniquet by four cycles of 5-min upper extremity occlusion and 5-min reperfusion.

Intracortical Bone Mechanics Are Related to Pore Morphology and Remodeling in Human Bone.

During aging and in osteoporosis, cortical bone becomes more porous, making it more fragile and susceptible to fractures. The aim of this study was to investigate the intracortical compression- induced strain energy distribution, and determine whether intracortical pores associated with high strain energy density (SED) in the surrounding bone matrix have a different morphology and distribution, as well as different remodeling characteristics than matrix with normal SED. Fibular diaphyseal specimens from 20 patients undergoing a jaw reconstruction (age range 41 to 75 years; 14 men and 6 women) were studied.

Local and systemic coagulation marker response to musculocutaneous flap ischemia-reperfusion injury and remote ischemic conditioning: An experimental study in a porcine model.

Background: Remote ischemic conditioning (RIC) administered by non-lethal periods of extremity ischemia and reperfusion attenuates ischemia-reperfusion injury. We aimed to investigate the local and systemic coagulation marker response to flap ischemia-reperfusion injury, and the effects of RIC on coagulation markers following flap ischemia-reperfusion injury.

Methods: A musculocutaneous latissimus dorsi flap was subjected to 4 h of ischemia followed by 7 h of reperfusion in 16 female Danish Landrace pigs (39 kg).

[Microsurgery in reanimation, lymphoedema and hand surgery].

Microsurgery is defined as surgery performed with the aid of ocular magnification. In Denmark, this is undertaken by four units. This review describes the history of microsurgery which evolved during the 1960s.

[Microsurgery in plastic surgery].

The most common indication for free flap surgery is breast reconstruction. Deep inferior epigastric perforator flaps are safe, quick and provide excellent cosmetic results. The reconstruction in head and neck cancer patients is more complex.

Direct comparison of postoperative monitoring of free flaps with microdialysis, implantable cook-swartz Doppler probe, and clinical monitoring in 20 consecutive patients.

Background: There is an increasing demand for successful free tissue transfer, with postoperative monitoring of flaps a key to early salvage. Monitoring methods have ranged from clinical techniques to invasive options, of which two are particularly applicable to buried flaps (Cook-Swartz Doppler probe and microdialysis). The evidence for these options has been represented largely in separate cohort studies, with no single study comparing these three techniques.
