  • Due to the fact that it reliably results in positive outcomes, lymph node flap transfer is becoming an increasingly popular surgical procedure for the prevention and treatment of lymphedema. This technique has been shown to stimulate lymphoangiogenesis and restore lymphatic function, as well as decreasing infection rates, minimizing pain, and preventing the recurrence of lymphedema. In this article, we investigate possible additional benefits of lymph node flap transfer, primarily the possibility that sentinel lymph nodes may be used to detect micrometastasis or in-transit metastasis and may function as an additional lymphatic station after the excision of advanced skin cancer.

  • Purpose: The purpose of this study is to determine the effect of platelet-rich plasma (PRP) on rat sciatic nerve regeneration in a 10 mm silicone chamber. Methods: A total of 6 inbred Lewis rats were used in this study. Bilateral sciatic neurectomy was performed on each rat. On one side, silicone chambers containing PRP solutions were implanted; on the contralateral side, the chambers without PRP were implanted as a control. In 12 weeks post-implantation, chambers were retrieved and both gastrocnemius muscles were excised. Nerves biopsy samples were examined under a light microscope after Masson trichrome staining. Results: Cross sections of the midpoints of PRP treated nerves were significantly larger and appeared more mature than those of controls. Conclusion: Based on morphological evidence, PRP has a positive effect on neural regeneration, and it may therefore be useful for treating peripheral nerve injuries.

  • Patients with advanced malignant tumors, including both jaws, is a challenging task for a head and neck surgeon. Current treatment landscape demonstrates good functional, anatomical, and aesthetic results in patients who could previously receive only palliative care. The extensive tissue defects resulting from oncological resections in the head and neck region require immediate reconstruction due to the exposure of vital structures and their contact with the external environment. A patient was operated using a three-team multidisciplinary approach involving simultaneous work of three specialized teams of maxillofacial and reconstructive microsurgeons, as well as an implantologist and a prosthodontist. This approach allowed simultaneous tumor resection with subsequent reconstruction of the intraoperative defect involving bilateral harvesting of two revascularized free fibular osteomusculocutaneous flaps with dental implantation and simultaneous rehabilitation of dentition with crowns.

  • In plastic and reconstructive craniomaxillofacial surgery, careful preoperative planning is essential to get a successful outcome. Many craniomaxillofacial surgeons have used imaging modalities like conventional radiographs, computed tomography(CT) and magnetic resonance imaging(MRI) for supporting the planning process. But, there are a lot of limitations in the comprehension of the surgical anatomy with these modalities. Medical models made with rapid prototyping (RP) technique represent a new approach for preoperative planning and simulation surgery. With rapid prototyping models, surgical procedures can be simulated and performed interactively so that surgeon can get a realistic impression of complex structures before surgical intervention. The great advantage of rapid prototyping technique is the precise reproduction of objects from a 3-dimensional reconstruction image as a physical model. Craniomaxillofacial surgeon can establish treatment strategy through preoperative simulation surgery and predict the postoperative result.
