Opis:
Soft tissue defects of the lower extremity pose an important surgical challenge, often because of inviability of primary covering. Therapeutic modalities of choice comprise of local perforator flaps, as well as of free flaps created with the use of microsurgical skills. However, these methods cannot be applied in patients with important comorbidities, and it is in such cases where the reverse sural flap proves to be the best solution. The aim of the study was to present the results of treating lower extremity defects with various modifications of the reverse sural flap. Material and methods. Sixteen patients, males aged 17-56 years, were operated on from 2007 to 2013. Diabetes with multiple complications, disseminated atheromatosis, and extensive soft tissue trauma involving the arteries crucial for microsurgica anastomoses were the most common reason disqualifying from the free and perforator-based flap techniques. Results. All of the patients achieved very good results; in two cases distal and marginal flap necrosis was observed which, once exiced, covered with granulation, and was successfully covered with a partialthickness skin graft. Conclusions. The reverse sural flap, technically easy, offers a viable, low-risk alternative to free and perforator-based flaps.

Opis:
Reconstructive techniques for extended posttraumatic or post-resectional nose defects are well described. Small defects can usually be closed using local flaps with a good esthetic result. Extended resections in the mentioned area require more complex reconstruction methods, including microvascular techniques. The Authors' presented a case of whole nose and partial cheek simultaneous reconstruction using three free flaps. Two auricular free flaps and one radial forearm free flap were used to cover the defect. Meticulous preoperative planning and harvesting of flaps enabled to achieve good esthetic and functional results.

Opis:
Postoperative reconstruction of tissue loss within the head and neck after extensive resections due to malignant neoplasms or traumas has always been a challenge for maxillo-facial surgeons or ENT physicians. Due to the complex anatomical structure of the head and neck region, every patient requires an individual approach and there is no standard method of management appropriate for all patients. The number of patients treated for malignancy is increasing year by year. The possibility of performing extensive resections in the head and neck region are conditioned by appropriate reconstruction. Aim. The aim of the paper is to present the reconstructive methods used in the Clinical Department of Maxillofacial Surgery, F. Chopin Hospital No. 1 in Rzeszow. A short review of the most commonly used flaps is presented, taking into account their advantages, disadvantages and surgical technique in terms of their usefulness in daily clinical practice.

Opis:
Introduction: The nose is the central and probably the most important organ of the face. In view of the three-dimensional shape and variety of tissues, reconstructive surgery after tumor resection in this anatomical region requires the surgeon’s knowledge of anatomy. Materials and Method: In the years 2010–2019, 48 patients were treated in the Oncological and Reconstructive Surgery Clinic for extended nasal tumors, which required the use of free microvascular flaps after resection for functional and aesthetic supply of anatomical structures of the nose. Results: In 48 patients, a total of 92 free microvascular flaps were used for nasal reconstruction including: radial forearm free flap in 24 patients, radial forearm free flap with radial bone in 14 patients, auricular free flap in 16 patients, radial forearm free flap in combination with auricle free flap in 7 patients, double auricular free flap in 6 patients, radial forearm free flap in combination with double auricular free flap in 4 patients. Total necrosis of the free flap was noted in 4 cases, partial in 6 patients. Conclusions: The presented surgical techniques using microvascular free flaps constitute a recognized method of treatment and should be used in everyday surgeon practice. The results demonstrated in this article allow to obtain optimal functional and aesthetic effects.

Opis:
This paper demonstrates the feasibility of using-a water tunnel for the visualisation of flow in airfoils with flight control systems in the form of slots and flaps. Furthermore, the issue of using water tunnels for scientific and training purposes was explained. The technology of 3D printed models for practical tests in a water tunnel was also presented. The experiment included conducting flow visualisation tests for three airfoil models: with the Clark Y 11.7% as the base airfoil and the same airfoil with a slot and a flap. Moreover, a modification to dye injection system was introduced. The presented results of flow visualisation around models with the use of dye, confirmed the effectiveness of the applied methodology. The results and conclusions may be utilized to verify most flow-related issues in hydrodynamic tunnels and can also be used as a training element.
W pracy przedstawiono uzasadnienie możliwości zastosowania tunelu wodnego do wizualizacji przepływu modeli profili lotniczych z mechanizacją w postaci slotów i klap. Ponadto przybliżono tematykę zastosowania tuneli wodnych w celach naukowych jak i szkoleniowych. Przedstawiono również technologię wydruku 3D modeli do testów praktycznych w tunelu wodnym. Eksperyment obejmował przeprowadzenie badań wizualizacyjnych dla trzech modeli profilu lotniczego: jako bazowy profil Clark Y 11.7% oraz ten sam profil ze slotem i z klapą. Ponadto autorzy pracy wprowadzili modyfikację wprowadzania barwnika przed badany model geometryczny umiejscowiony na trzymaku w przestrzeni pomiarowej. Przedstawione wyniki zobrazowania przepływał w:okół modeli za pomocą barwnika potwierdziły skuteczność zastosowanej metodyki prowadzenia eksperymentu na charakterystycznych kątach natarcia. Wyniki i wnioski można wykorzystać do zweryfikowania większości zagadnień przepływowych w tunelach hydrodynamicznych jak również mogą posłużyć jako element szkoleniowy.

Opis:
The main purpose of this article was to study flaps application influence on airfoil, which flies in the wing in ground effect with lift, and drag coefficients changes. Wing in ground effect occurs in the direct proximity of ground, it makes lift coefficient higher than in free stream flight, also decreases drag coefficient. WIG effect craft can be an alternative for traditional aircraft, but also for marine transportation. The article presents wing in ground effect creation mechanism description with height coefficient explanation, also presents experimental analysis of lift coefficient with reference to height coefficient. Airfoil with flaps simulation and for free stream flight. Application of flaps makes the wing in ground effect more efficient by lift coefficient rise, what provides also to drag coefficient rise. Flaps provide to absolute pressure rise under the airfoil. It allows to fly slower without lift force change or to make aircraft start shorter without risk of stall. The article shows also conditions and results of Ansys Fluent software simulation for NACA M8 airfoil for angles of attack equal to: 0°, 6°, 10° for three different cases: free stream flight, wing in ground flight with the clear wing, wing in ground flight with flaps, and conditions of analysis convergence.
