A non-standard surgicall approach in malignant retroperitoneal tumor treatment was used, which includes simultaneous resection and reconstruction of the infrarenal segment of aorta and inferior vena cava. The total vascular recunstrustion time was 40 minutes and 15 minutes out of total time was arterial ischemia. The postoperative period was complicated by the right urethral fistula and the limited fluid concentration in the surgical area. On day 25th of the post-operative period patient discharged from the hospital. We believe that such a tactic can be safe and effective in case of meticulous patients selection and the multidisciplinary and multi-team approaches application.

The term “proprioception” is defined as the conduction of sensory information deriving from proprioceptors that have an impact on conscious sensations, posture and trans-segmental sense. An ACL injury may lead to functional knee joint instability. According to research, this may result in impaired movement sensation and joint position. The purpose of this study was to evaluate the joint position sense (JPS) in patients before arthroscopic ACL reconstruction and 5 months after the surgery. The examinations were conducted in a group of twelve specifically selected male patients. The examination procedure consisted of JPS measurement in both lower limbs (the operated and the healthy one) during active extension in a range of angles: 30, 45, 60°. The level of significance was: p < 0.05. The analysis of variance performed for repeated measurements (ANOVA) did not indicate any statistically significant differences of JPS in comparisons made between the operated and the healthy limb. Statistical values for the absolute, relative, and variable errors were p = 0.7684, p = 0.1546, p = 0.5694 respectively. The obtained results do not indicate any limitation of proprioception in patients with ACL injury before the intervention or half a year later.

Introduction: The aim of the study was to prove that a combination of visual surgical planning (VSP) and cone beam computed tomography (CBCT) is an optimal technique in fibular free flap reconstructions after complex tumor resections in the head and neck region and that it leads to better functional and aesthetic outcomes. Material and method: Six patients (3 females, 3 males) with head and neck tumors were included in the study. The region concerned midface in 2 cases and mandible in 4 patients. On the basis of computed tomography of the head, fibular free flap (FFF) reconstruction was planned with the VSP technique. The 3D-printed models were prepared. At the beginning of the operation and a few minutes after the reconstruction, an xCAT CBCT by XORAN was performed. Minor corrections of the angles of the reconstructed bony parts were made where needed. The time of the operation was assessed for each case. Functional and cosmetic results were evaluated in a 1-year follow-up. Results: The mean time of operation was 6 hours and 48 minutes, which was approximately 1hour and 40 minutes less than standard reconstructive surgery. Functional recovery was achieved in all patients. Aesthetic result was unsatisfactory for 2 patients due to insufficient soft tissue masses of FFF. Conclusions: The authors claim that intraoperative CBCT imaging, regardless of the cost, improves the accuracy of aesthetic outcome of reconstructive surgeries based on VSP, especially in the region of the midface and the mandible. Further studies on a higher number of subjects are required.

CBCT is a relatively new diagnostic imaging method. It was first used in 1982 at the Mayo Clinic Biodynamics Research Laboratory [1], and has been commercially used in dentistry since 2001. It differs from multidetector computed tomography in terms of implementation technique and some parameters. A low dose of radiation is its greatest advantage, thanks to which many specialists, including ENT doctors and reconstructive surgeons, are more willing to use it. In otorhinolaryngology, CBCT is applied in pre- and perioperative diagnostics in both rhinology and otology. In reconstructive surgery, CBCT facilitates precise planning of the flap and intraoperatively allows a perfect match of the reconstructed tissue elements. In the article, the authors present current information on CBCT in ENT obtained on the basis of a review of Polish and foreign literature and share their own experience in its application in reconstructive surgery within the craniofacial region.

Introduction: Central giant cell granuloma (CGCG) is a benign tumor-like lesion of a bone, mainly localized in the mandible. It usually occurs in children and young adults under 30 y/o., predominantly in females. The etiology of the disease remains unknown. Clinically, two types of CGCG have been distinguished – a non-aggressive one, in which the granuloma grows slowly, often asymptomatically, and aggressive type for which the following features are characteristic: increased bone destruction, severe pain, large size, rapid growth, high recurrence rate and complications such as root resorption, tooth displacement or cortical bone perforation. The treatment of CGCG depends on its type. In cases of granulomas of the aggressive type, the following therapeutic procedures have been proposed: intralesional corticosteroid injections, interferon and calcitonin therapy as well as immunotherapy with anti-bone resorptive human monoclonal antibody like denosumab. However, in most cases nonsurgical treatment is insufficient. Local curettage of the lesion also entails a high risk of relapse. Therefore, radical surgical resection, often combined with bone reconstruction, is the recommended way of treatment for aggressive CGCG. Case report: The authors present a case of a 31-year-old female patient treated for central giant cell granuloma of the mandible at the Department of Oncological and Reconstructive Surgery, Maria Sklodowska Curie Memorial Cancer Centre and Institute of Oncology in Gliwice. The resection of CGCG localized in the mandible on the right side together with fibular free flap reconstruction has been performed, with satisfactory aesthetic effect. The immunohistochemical examination indicated a positive stain reaction for CD68 and CD31 and expression of Ki67 marker was 13%. No complications were reported in the postoperative period. The six-month follow up revealed no relapse. Conclusions: The authors claim that radical surgical management should be performed in all patients with CGCG of the aggressive type. Fibular free flap is recommended for reconstruction in large bone defects. This allows tumor-free margins at the resection and satisfactory cosmetic outcome. Quality of life and facial appearance can be improved with dental implantation after a certain period of remission. A regular follow-up is essential as an element of holistic oncological process.

Wstęp. Wtórna deformacja płytki paznokciowej typu „hook nail” jest częstym skutkiem amputacji palca na poziomie paliczka dystalnego. Ubytek paliczka dystalnego, będącego podparciem kostnym, jak i ubytek tkanek miękkich w obrębie opuszki powoduje zagięcie płytki paznokciowej w kierunku dłoniowej, co skutkuje bólem, upośledzeniem funkcji oraz defektem kosmetycznym palca. Istnieje wiele technik chirurgicznych mających na celu odtworzenie prawidłowego wzrostu paznokcia, takie jak: wykorzystanie płatów skórnych, przeszczepy skóry i kości, jak również transfer mikrochirurgiczny. Najczęściej jednak żadna z wyżej wymienionych metod nie pozwala na odtworzenie pełnej, utrzymującej się korekcji deformacji paznokcia. Opis przypadku. U ośmioletniego chłopca doszło do amputacji całkowitej części paliczka dystalnego palca środkowego, rana została zaopatrzona pierwotnie szwami skórnymi. Około 4 lata później pacjent został przyjęty do kliniki z powodu wtórnej deformacji płytki paznokciowej typu „hook nail”, z zagięciem w kierunku dłoniowym i skośnym, która powodowała dolegliwości bólowe oraz defekt kosmetyczny. Badanie radiologiczne wykazało brak większości paliczka dystalnego. Leczenie. Wykonano chirurgiczną rekonstrukcję ubytku paliczka dystalnego z wykorzystaniem przeszczepu kości z talerza biodrowego, ustabilizowanego dwoma drutami „K”. Ubytek skóry w obrębie opuszki palca został pokryty uszypułowanym płatem z okolicy kłębu kciuka. Płat został odcięty po około 4 tygodniach. Druty „K” zostały usunięte po 4 miesiącach. Wyniki. Leczenie było dobrze tolerowane przez pacjenta, w trakcie leczenia nie wystąpiły powikłania. Przeszczep kości stanowił podparcie dla macierzy paznokcia podczas okresu gojenia. Uzyskano prawidłowy wzrost paznokcia oraz zadowalający efekt kosmetyczny. W trakcie około 2-letniej obserwacji pacjenta, doszło do niewielkiego odchylenia rotacyjnego płytki paznokciowej, co mogło być skutkiem częściowej resorpcji przeszczepu kostnego oraz wzrostu pacjenta. Dla pacjenta wynik końcowy leczenia jest satysfakcjonujący. Wnioski. Całkowite oraz trwałe odtworzenie prawidłowej płytki paznokciowej i obrysu opuszki jest praktycznie nieosiągalne. W opisywanym przypadku klinicznym zastosowane leczenie pozwoliło na odtworzenie zadowalającego efektu zarówno funkcjonalnego jak i kosmetycznego.

Introduction. Hook nail deformity is a common complication following fingertip amputations. Loss of distal bone support and palmar pulp tissue, results in the volar curving of the nailbed, which may cause pain, and aesthetic and functional problems. A few procedures have been described to address nail deformity, including flaps, skin and bone grafts, and microsurgical transfer. Unfortunately, none of the techniques provides reliably good and persistent correction. Case report. An 8-year-old boy sustained amputation of the distal phalanx of the middle finger and underwent surgical closure of the wound. After 4 years, the patient was admitted to our Department due to a deformed hook nail, which was aesthetically distressing. The hook nail was curved volarly and obliquely. The radiographs showed the lack of a significant part of the distal phalanx. Treatment. Surgical reconstruction of deficient distal phalanx was performed. The iliac bone graft, inserted into the distal phalanx, was stabilized with two K wires. A Pedicled flap of full-thickness from the thenar was used to cover skin loss over the fingertip. Pedicle division was performed at around 4 weeks. “K” wires were removed after 4 months. Results. The procedure was well-tolerated by the patient, and no complications occurred. Bone graft provided solid support for the nail bed during healing. Adequate growth and aesthetics of the hook nail were achieved. At 2 years follow-up, slight rotation of the nail was observed, which could have resulted from partial graft resorption and growth of the patient. The patient was satisfied with the treatment. Conclusions. Although perfect restoration of the nail bed length and pulp contour remains unobtainable, our result showed stable correction of the hook nail deformity.
