    Abstract Traumatic dislocation of the eye is usually encountered in high-energy injuries. These include traffic accidents, accidents at work, sporting accidents, falling from a height, impact of the hooves or horns of animals, gunshot injuries, and physical assault. Such incidents are accompanied by facial soft tissue damage and injuries to the facial skeleton, especially the orbit, and can be associated with varying degrees of dislocation of the eye. We describe a rare case of non-fatal traumatic eye dislocation into the maxillary sinus, coupled with an orbital fracture resulting from a physical assault on a 63-year-old woman. The cause of death was asphyxiation due to manual strangulation and mechanical asphyxia. Even though dislocations of the eye are relatively rare, forensic pathologists should be aware of such injuries to correct assessment of injury mechanism. The available literature regarding eye dislocation is summarized, and the forensic issues applicable to the assessment of such cases are reviewed.

    Abstract Background: Different methods of temporomandibular joint imaging are presented and discussed. Research reports published from 1979 to 2002 have been evaluated.
    Method and results: The aim of this paper is to summarize the main findings from research. Basic X-ray examination is the most readily available method of imaging which usually does not have any contraindication. The use of computer tomography offers all advantages of tomographic scanning in different layers and projections, imaging soft tissues close to the joint and the possibility of "3D" reconstruction of bone structures. In case of joint dysfunctions and internal joint derangement, it is more preferable to use nuclear magnetic resonance for the depiction of the joint structures. To make a diagnosis more efficient, miniinvasive diagnostic methods are becoming necessary. Arthroscopy allows direct visual control of the joint space with the possibility of therapeutic help in cases when conservative treatment has failed. Ultrasonography, as a completely non-invasive procedure, is applied even in diagnosing functional temporomandibular defects. In these cases the diagnostic value of ultrasonography is almost comparable with this of nuclear magnetic resonance.
    Conclusions: So it is possible that, together with the improvement of the equipment, development of the diagnostic methods used during the treatment of temporomandibular joint defects could continue in this direction.

    Title translation Pedicled Flaps for Reconstruction of Head and Neck Region.
    Abstract Background: There has been a consistent increase in the number of publications on pedicled flaps for the reconstruction of post ablation defects in the oropharyngeal area. In principle, tissue is lifted from a donor site and moved to a recipient site without disruption of blood supply. The donor site is an exact anatomically defined region of tissue that is capable of sustaining its own blood supply. The benefits of pedicled flaps include lower technical demands that obviate the need for microsurgical anastomosis and shorter operating times. For this reason, they are mostly indicated in elderly and at risk patients. The aim of this paper is to describe our experience with the regional (pedicled) (submental, supraclavicular) flaps with a focus on reliability, function, cosmesis, donor site morbidity, and oncological safety.
    Material and methods: Reconstructive techniques using distal flaps are described in 12 patients. A submental flap for reconstruction was used in 7 patients. In 5 patients, we used the supraclavicular flap. A total of 9 patients were treated primarily for squamous cell carcinoma of the orofacial region, and 3 for low-grade adenocarcinoma of the small salivary gland.
    Results: In 5 patients, there was successful engraftment of the submental flap. Ischemia and necrosis of the edges of the flap occurred in 1 case. In one patient, the 3rd day after surgery, the flap was almost totally necrotised. The supraclavicular flap in 4 patiets healed completely, 1 time during the postoperative period it was infected with partial loss of the outer part of the flap from the pre auricular region. In one case there was necrosis of the terminal part of the flap in the reconstructed part of the tongue, the defect was healed by granulation tissue. In all patients, after reconstruction using supraclavicular and submental flaps, the donor site closed primarily with minimal morbidity.
    Conclusion: Regional (pedicled) flaps are thin, and pliable with good cosmetic and functional results. Reconstruction using these flaps can be accomplished in one-stage with minimum morbidity of the donor site.Key words: pedicled flap - surgical flap - head and neck cancersSubmitted: 11. 5. 2017Accepted: 5. 11. 2017 The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study.

    Abstract Objective: Arthrocentesis of the temporomandibular joint is a minimally invasive method of treatment located at the boundary between conservative and surgical therapy. It is usually performed on an out-patient basis under local anaesthesia. These days, arthrocentesis of the temporomandibular joint is used not only in cases of acute closed lock but also in the treatment of various temporomandibular disorders. The most frequent indication is acute anterior displacement of the articular disc without reduction. Treatment using occlusal splint is one of the most frequently used methods of conservative treatment. It is used mainly in the case of discopathies and myofascial pain.
    Aim: The aim of the study was to confirm that simultaneous use of the occlusal splint and arthrocentesis makes the treatment more effective in the case of detected disc dislocation without reduction.
    Materials, methods and results: From 2008 to 2013, 144 patients underwent arthrocentesis simultaneously using occlusal splint in the treatment of chronic closed lock. The study group consisted of a 130 (90.3%) women and 14 (9.7%) men. After 3 months of therapy, a good treatment outcome was found in 98 (68.1%) patients, 12 (85.7%) men and 86 (66.2%) women. The treatment did not have any effect in 46 (31.9%) patients, 2 (14.3%) men and 44 (33.8%) women.
    Conclusion: The simultaneous use of the occlusal splint and arthrocentesis makes the treatment more effective in the case of detected joint disc dislocation without reduction.

    Abstract Background: Arthrocentesis is a very gentle method for lavage of the joint space. The principle consists in the introduction of a pair of needles into the upper joint space and subsequent lavage using physiological saline or Ringer's solution. Arthrocentesis of the temporomandibular joint is used in both cases of acute closed lock and treatment of various temporomandibular disorders.
    Methods: A literature search in Pubmed database, using key words: Temporomandibular joint (TMJ), Arthrocentesis, indications, technique, results.
    Conclusion: Arthrocentesis of the temporomandibular joint is a minimally invasive treatment method at the boundary between conservative and surgical therapy. It is usually performed on an out-patient basis under local anaesthesia. It is used both in cases of acute block caused by displacement of the articular disc and also to treat degenerative inflammatory diseases of the joints. The main objective of arthrocentesis is to wash out inflammatory mediators, release the disc, break adhesions, eliminate pain and improve joint mobility. It is a method with a minimum number of complications, it is simple and not demanding in terms of instruments, and it can be performed repeatedly. For this reason, it has become widespread and very popular in the treatment of internal disorders of the temporomandibular joint.

    Abstract Objective: Oropharyngeal cancers are a biologically heterogenous group of tumors with diverse risk factors including tobacco, alcohol, HPV, inherited disorders, the acquired immunodeficiency of Karposi's Sarcoma and non Hodgkin's lymphoma. In the Czech Republic, oropharyngeal cancers represent around 2% of all cancers. The treatment of these tumors is long and complex. Reconstructive procedures in maxillofacial oncosurgery demand good interdisciplinary collaboration and great professional preparedness of the surgical and nursing team. Patient age and stage of disease, including the presence of metastases are of key importance. A prerequisite for the success of surgical treatment is removal of the tumor with a sufficient safety margin. Reconstructive procedures then follow.
    Aim: To highlight the importance of radical tumor resection and describe reconstruction of the defect in a group of our patients.
    Methods and results: From 2008 to 2013, 23 patients with oropharyngeal carcinoma underwent radical surgical removal of tumor, followed by reconstruction of postoperative defects using distant and free flaps. The histopathology showed predominantly squamous cell carcinomas and one of Merkel cell carcinoma. 16 patients had malignant disease detected in III-IV. In only 7 cases was treatment initiated in the first and second stages of the disease. In these patients, the tumors were removed with a safety margin of healthy tissue and in none, did the basic cancer recur . The postoperative course in terms of flap engraftment and overall condition of the patient was uneventful. All of these patients still enjoy a good life quality with a current mean survival in range 5 - 76 months. Radical surgical removal of a malignant tumor in the early stages of the disease is associated with fewer postoperative complications and longer survival.
    Conclusion: To avoid the risk of local and/or systemic postoperative complications, appropriate patient selection is important. Overall, the traditional, classic reconstructive procedures with the use of prostheses, in many cases is still the best option in our experience.
