Biomechanical analysis of the rigid fixation of zygoma fractures: an experimental study.

In this experimental study, the goal was to test the sufficiency of actual fixation plates in zygomatic complex fractures and the efficiency of a modified plate at the zygomaticofrontal suture in a suitable model, which was designed for biomechanical study. To address this issue, a zygomatic fracture model produced by using a cadaveric cranium was simulated and the fractures were fixed by the actual and modified fixation materials. The force simulating masseter muscle pull was applied with the Lloyd material testing apparatus, and the rotation of the zygoma was determined using displacement transducers. In this study, there were three different experimental groups. Although miniplates at the zygomaticomaxillary buttress and microplates at the infraorbital rim were used in all three groups, three different plates (miniplate, microplate, and modified plate) were used at the frontozygomatic suture in these groups. Rotational displacement of the zygoma with the effects of simulated masseter muscle force was determined. According to the results obtained, microplates are not effective in stabilizing the frontozygomatic suture when the masseter muscle forces are within physiological range. Although miniplates stabilize zygomatic complex fractures, it was shown that modified microplates, which have no ondulation along the plate border, have a higher resistance to rotation than that of the conventional plates. The rotation angle at the instant of fracture with microplates was 4.59°, and that with miniplates was 1.26°. The maximum rotation angle with modified microplates was 0.32°. Modified microplates designed for the fixation of fractures in the zygomatico-orbital region have been shown to be suitable in a well-designed experimental model and might be appropriate for clinical use.

Nutritional Therapy in Burns

Yanık, ısı, elektrik, kimyasal maddeler veya radyoaktif ışınlar ile meydana gelen doku harabiyetidir. Son yıllarda yanık yaraları insidansı azalmıştır. Ancak tüm dünya genelinde oldukça önemli bir problem olduğu ve her yıl birkaç milyon insanın yanıktan etkilendiği bilinmektedir. Yanık, tüm organizmayı etkileyen ve oluşturduğu fizyopatoloji ile prognozu belirleyen çok kapsamlı bir travmadır. Yanık hastasında cilt bariyeri bozulduğu için ciddi sıvı, elektrolit, protein, mineral kayıpları olmakta; yoğun katabolik durum, enfeksiyonlar ve yara iyileşmesi için artan gereksinimler nedeni ile protein, enerji ve mikrobesin ögesi eksiklikleri gelişebilmektedir. Bu sebeple tıbbi beslenme tedavisi yanık yaralanmasının ilk anından tedavinin sonuna kadar en temel basamaklardan birini oluşturmaktadır. Bu çalışmada yanık yarasının tedavisinde tıbbi beslenme tedavisi ve önemi güncel bilgiler ışığında anlatılacaktır.

Linear Cutaneous Atrophy Development Due to Intralesional Corticosteroid Therapy: Case Report and Review of the Literature

Intralesional corticosteroid administration is a procedure involving the injection of a steroid solution into abnormal skin, especially with scars and/or keloids. After the application of topical corticosteroids, atrophy may rarely develop in the skin and subcutaneous tissue. When the developed atrophy of the skin becomes permanent, aesthetic problems that lead to psychological problems negatively affect the daily life of the patients. In this study, pathogenesis of rarely developing linear skin atrophy induced by intralesional corticosteroid administration during scar treatment, clinical and treatment outcomes were presented in the light of the literature.
