Objectives Many studies have investigated the surgical outcome and predictive factors of acoustic neuroma using different approaches. The present study focused on large tumors due to the greater likelihood of internal acoustic meatus involvement and the greater application of surgical intervention than radiosurgery. There have been no previous reports on outcomes of internal acoustic meatus tumor removal. We investigated the impact of the extent of internal acoustic meatus tumor removal using a translabyrinthine approach for large acoustic neuroma surgery and predictive factors of tumor control. Methods This retrospective study reviewed 104 patients with large cerebellopontine angle tumor >3 cm treated by translabyrinthine approach microsurgery. Predictive factors of postoperative facial palsy, tumor control, and extent of internal acoustic meatus tumor removal were assessed. Results The mean tumor size was 38.95 ± 6.83 mm. Postoperative facial function showed 76.9% acceptable function (House–Brackmann grade 1 or 2) six months after surgery. The extent of internal acoustic meatus tumor removal was a statistically significant predictor factor of poor postoperative facial function. Younger age, larger tumor size needing radiosurgery, and more extensive removal of tumor were associated with better tumor control. Conclusion More extensive internal acoustic meatus tumor removal was associated with poor postoperative facial function and better tumor control.

Object. The aim of this study was to determine if factors such as postoperative hearing, facial function, headaches, or other factors have an impact on self-assessed quality of life (QOL) after acoustic neuroma surgery. Methods. The SF-36 and seven additional questions on the impact of surgery on the QOL were sent to 135 consecutive patients who had undergone acoustic neuroma surgery. The Spearman rho correlations were calculated for each of the eight categories of the SF-36 (general health, physical functioning, physical role limitations, emotional role limitations, mental health, energy/vitality, pain, social functioning). The results were correlated with patients' sex, age, persistent headache, years since surgery, postoperative hearing level, and facial function. The response rate was 74.8%. The transformed scores of the eight categories of the SF-36 were lower than age-matched healthy controls in approximately half of the categories. The strongest trend toward lower scores with statistical significance in two categories was persistent headaches. Some categories demonstrated trends toward lower scores with females or age older than 55 years. Postoperative hearing and facial functioning, and time since surgery showed no statistically significant impact on QOL measured by the SF-36. Responses to the additional questions indicate that hearing, facial function, and headache influenced people's feelings about surgery and had an impact on their return to work. Conclusions. The QOL scores are not consistently lower than population normative values compared with different normative studies. The strongest correlation was between the presence of persistent headache and QOL. Other correlations were not consistent in all categories, and few were statistically significant. These trends in some categories do not explain the difference seen between patients after acoustic neuroma surgery in this study and normal populations in other studies.

AbstractContemporary global power competition has turned the world into a hybrid battlefield. In modern battlefield, authoritarian regimes have the strategic advantage of being irresponsible, reckless and aggressive. This advantage is combined with the ability of the authoritarian regimes to find cheap and effective - short of war - solutions for achieving geopolitical objectives. In past decades authoritarian regimes such as Russia and China have been actively applying hybrid strategies against the Western dominated rules based international system. Those strategies are being constructed based on identification and utilization of the vulnerabilities of the democratic political systems, institutions and societies. Pandemic crisis caused by unpredictable and unprecedented spread of the mutated new Corona virus, have underlined vulnerabilities and opened up new possibilities for the hybrid warfare. The pandemic influences every power on the global stage, but will COVID-19 be a turning point for the Euro-Atlantic Security environment?

AbstractObjective:This study aimed to evaluate retrospectively the results of experience with end-to-end anastomosis of cranial nerves VII and XII, performed due to transection of the facial nerve during acoustic neuroma removal.Methods:We assessed the facial reanimation results of 33 patients whose facial nerves had been transected during acoustic neuroma excision via a retrosigmoid approach, between 1985 and 2006, and who underwent end-to-end hypoglossofacial anastomosis. We compared the facial nerve functions of patients receiving short term (two to three years) and long term (more than three years) follow up, and we assessed any complications of the anastomosis.Results:A House–Brackmann grade III facial function was achieved in 46.2 and 86.4 per cent of the patients in the short and long term, respectively. House–Brackmann grade IV facial function was achieved in 53.8 and 13.6 per cent of the patients in the short and long term, respectively. There was a statistically significant difference between the facial recovery results, comparing the short and long term follow-up periods (p = 0.03). Disarticulation was the most common complication, seen in 19 (57.6 per cent) patients; numbness of the tongue was the next commonest (10 (30.3 per cent) patients). None of the patients developed dysphagia.Conclusion:Despite such morbidities as disarticulation and tongue numbness, end-to-end hypoglossofacial anastomosis is still an effective procedure for the surgical rehabilitation of static and dynamic facial nerve functions. Significant improvement in facial nerve function can occur more than three years post-operatively.

Introduction. The research work defines the current significance of international sanctions, examines the types of sanctions, the goals of their imposition and the consequences for the international system. As an example, anti-Russian sanctions and retaliatory measures are being analyzed, as well as their influence on relations between the states. In the study an assessment of the development of Russian-German cooperation in various fields before and after the imposition of sanctions is given.Methodology and sources. Such research methods as analysis, synthesis, comparison, statistical methods are used in the research work. Import-export relations between Russia and Germany are analyzed in the paper.Results and discussion. Russia incurs heavy losses from sanctions compared to the European Union. Anti-Russian sanctions do not contribute to the development of free international trade. The European Union is having difficulty maintaining transatlantic economic relations. The imposition of US extraterritorial sanctions is detrimental to German and other European companies. Both European countries and Russia have internal problems, which are aggravated by the sanctions confrontation.Conclusion. Despite all the existing problems and obstacles that stand in the way of bilateral relations, there are positive trends in them. Russia and Germany, in general, have adapted to the sanctions regime. Anti-Russian sanctions will probably not be lifted in the short term.
