  • Benign and malignant bone tumors occur most commonly around the knee. The proximal tibia is the most technically demanding site for limb salvage surgery. The most difficult problem using an endoprothesis for proximal tibial resection has been reconstruction of the extensor mechanism. After excision of proximal tibia, we resected distal femur and made a composite with resected distal femur, low heat treated autogenous proximal tibia and endoprothesis. Patella was fixed into the resected down-loaded distal femur. This article shows the new technique and the results of reconstruction of extensor mechanism after prosthetic replacement of the proximal tibia.

  • We report here on a case of performing a redo-operation for a 65-years-old male patient who had prosthetic endocarditis after reconstruction of the fibrous skeleton due to infective endocarditis 8 years earlier. An aortic annular abscess with a 1cm sized subvalvular abscess and mobile mitral valve vegetation with destruction of the fibrous skeleton was shown on the preoperative echocardiography. An emergency operation was performed due to heart failure. Reconstruction of both the aortic and mitral annuli and the fibrous skeleton was done by using two separate bovine pericardial patches and then mechanical valves were implanted. The postoperative echocardiography shows no paravalvular leakage. The patient has been followed up with no symptoms.

  • Functional and esthetic recovery through reconstruction of the oral and maxillofacial system is important for patients who underwent mandibulectomy due to lesions such as oral cancer. The fibula free flap, which is frequently used in the reconstruction of the mandible, is easy to prosthetic restoration with implant placement. However, patients with growing periods have difficulty in treatment with implants when the size of the fibula is small and residual growth remains. This case is an 11-year-old female patient who underwent mandibulectomy due to osteosarcoma and reconstruction of the mandible using a fibular free flap. Functional and esthetic recovery were obtained through prosthetic restoration using implant-supported fixed prostheses. Implantation site, number of implants, and type of prostheses were considered. Implant-supported fixed prostheses were delivered at 13 years old, and after an additional 1 year observation, stable results were obtained. However, observing changes in the maxillofacial system through further examinations is necessary.

  • Individuals with cognitive disabilities face many barriers to oral care, often suffering from partial or complete edentulism. While the use of implant reconstruction is becoming more common in general population, such care is still being used infrequently in individuals with intellectual impairment. Because of the patients'oral hygiene practice is poor, special need is required for prosthetic design. These two cases were restored by prostheses using implants. Prosthetic modalities were different but the implants were fully osseointegrated, presenting satisfactory functional and esthetic conditions without clinical or radiographic signs of alterations or pathologies. We report that it is good for cognitive disabilities to give prosthetic treatment using implants.

  • This case study is aimed at introducing a full-mouth rehabilitation of a patient with severe tooth wear using fixed prosthesis. This is a case report of a patient with severe wear dentition with changing vertical dimension. In line with using prosthetic treatment, patient adaptation was verified with provisional restorations followed by diagnostic wax-up. Function, esthetics, and occlusal stability were verified during a 4-week follow up period. Prosthodontic reconstruction based on systemic analysis, diagnosis, and treatment plan led to satisfactory results after delivery of definitive prosthesis. Prosthetic treatment of severe wear dentition was functionally and esthetically successful. Dentists and dental technicians would be able to develop better treatment approaches using fixed dental prosthesis.

  • Background Breast reconstruction refers to the rebuilding of a woman's breast using autologous tissue or prosthetic material to form a natural-looking breast. It is increasingly offered to women undergoing mastectomy for breast cancer. However, there is no systematic analysis available for the expanding area of research on breast reconstruction. Methods A bibliometric method was used to obtain a view of the scientific production about breast reconstruction by data extracted from the Institute for Scientific Information (ISI). Specific parameters were retrieved from the ISI. Articles about breast reconstruction were analyzed to obtain a view of the topic's structure, history, and document relationships using HistCite software. Trends in the most influential publications and authors were analyzed. Results The number of articles was constantly increasing. Most highly cited articles described the methods of flap construction in the surgery. Other highly cited articles discussed the psychological or emotional aspects of breast reconstruction, skin sparing mastectomy, and breast reconstruction in the irradiated breast. Conclusions This was the first breast reconstruction scientometric analysis, representing the characteristics of papers and the trends of scientific production. A constant increase in the number of breast reconstruction papers and also the increasing number of citations shows that there is an increasing interest in this area of medical science. It seems that most of the research in this field is focused on the technical aspects of surgery.

  • Background: The free vascularized fibula flap presents many advantages such as sufficient length of the bony segment, good vascularization, better quality of the bone, and a long vascular pedicle, but it is also associated with some disadvantages with regard to prosthetic rehabilitation because of its limited height. Improvement in bone height is necessary for ideal dental implant treatment of reconstructed mandibles. Case presentation: For two squamous cell carcinoma patients, mandibular bone reconstruction was performed secondarily with the peroneal flap after tumor resection. Since the bone height was insufficient at the time of implant treatment, occlusion reconstruction by dental implant was performed after vertical distraction osteogenesis. Conclusions: Vertical distraction osteogenesis is a suitable treatment option for alveolar ridge deficiency resulting from fibula transplantation for mandibular reconstruction following tumor surgery.

  • Loss of continuity of the mandible destroys the balance and symmetry of mandibular function, leading to altered mandibular movements and deviation of the residual fragment towards the resected side. Apart from deviation, other dysfunctions include difficulty in swallowing, speech, mandibular movements, mastication, and respiration are accompanied. In general, surgical reconstruction is considered first then proceeds to the prosthetic restorations. However, patients with systemic disease such as BRONJ (Bisphosphonate related osteonecrosis of the Jaw), surgical reconstruction may be limited. Thus, the prosthetic restoration remains as the only resort. Numerous prosthetic methods are employed to minimize deviation and to improve masticatory efficiency, function and esthetics. If a removable partial denture is the selected treatment modality, maximum stability of the partial denture base may be accomplished with a functional impression procedure by means of eliminating lateral and horizontal forces caused by the functional movements of the lips, cheeks and tongue. Also, Twin occlusion is used to obtain a favorable occlusal relationship and check support for esthetics. The purpose of this case report is to demonstrate how neutral zone impression technique and twin occlusion scheme were applied to restore a hemi-mandiblectomy patient with BRONJ syndrome to achieve satisfactory results in functional and esthetic aspects.

  • Knee revision arthroplasty following peri-prosthetic joint infections is a formidable challenge. Patients are at a high risk of recurrent infection, and the soft tissue over the revised implant is often of questionable quality. Flap reconstruction has improved the salvage rates of infected arthroplasties, and should be considered in all cases of revision arthroplasty. We present a challenging case requiring staged reconstruction with two free latissimus dorsi flaps after the initial use of a medial gastrocnemius flap.

  • Background In breast reconstruction using implants after unilateral mastectomy, it is challenging to create a natural, ptotic contour, and asymmetry is a potential drawback. To achieve breast symmetry and an ideal shape for both breasts, we performed contralateral augmentation in patients undergoing breast reconstruction with implants. Methods Patients underwent unilateral mastectomy and 2-stage reconstruction. During the second stage of the procedure, contralateral augmentation mammoplasty was performed. Preoperatively, we obtained the patients' demographic information, and we then assessed breast volume, the volume and dimensions of the inserted implants, and complications. Breast symmetry was observed by the surgeon and was assessed by measuring the disparity between the final volume of each breast. Results Contralateral augmentation was performed in 52 cases. When compared to patients who did not undergo a contralateral balancing procedure, patients who received contralateral augmentation were younger, thinner, and had smaller breasts. During implant selection for contralateral augmentation, we chose implants that were approximately 1 cm shorter in width, 1 level lower in height, and 1 or 2 levels lower in projection than the implants used for reconstruction. The postoperative breast contours were symmetric and the final volume discrepancy between each breast, which was measured by 3-dimensional scanning, was acceptable. Conclusions We demonstrate that contralateral augmentation can be recommended for patients who perceive their breasts to be small and not beautiful in order to achieve an ideal and beautiful shape for both breasts. Furthermore, this study offers guidelines for selecting the implant that will lead to the optimal aesthetic outcome.
