The authors studied the age-related features of the vascular organization of the adenoid tissue. A total of 46 subjects (n=46) were examined; they were divided into two groups one of which included subjects at the age from 7 to 12 years (n=25) whereas the other group was comprised of 21 subjects at the age from 18 to 42 years (n=21). 29 participants of the study were men (63%) and 17 (37%) women. The histological examination of the adenoid tissue revealed the characteristic changes in the adenoid vasculature in the subjects of either age-group. The subjects above 18 years of age were shown to have developed sclerosis and hyalinosis of the vascular walls with the formation of cavernously dilated plethoric veins having the thickened rigid walls. The morphological changes in the connective tissue (basal) layer were documented responsible for the manifestation of the phenomenon of 'immersion' of the lymphoid tissue with the well developed microcirculatory bed. It is concluded that the results of the histological examination can serve as one of the indicators for the use of electrophysical methods to perform adenotomy in the patients older than 18 years.

Introduction: Allergic rhinitis (AR) is a critical disease related to otorhinolaryngology, allergology, and pediatrics worldwide due to its high prevalence and treatment costs. This article considers its prevalence based on regional characteristics of sensitization and the quality of patients with allergic rhinitis in North Vietnam. Methods: The study was conducted from June to September 2018 by the Department of Otorhinolaryngology, Thai Nguyen Central General Hospital, Vietnam. A total of 158 patients with symptoms of chronic rhinitis, aged 5-70 years, were examined. All patients with allergic rhinitis were subjected to standard, specific allergological tests, such as skin scarification tests, the determination of specific IgE in the blood, and statistics according to the NOSE scale. All the patients were also examined by otolaryngologists. Results: Among the 158 patients identified with chronic year-round rhinitis, 64 patients were diagnosed with allergic rhinitis. The sensitization to house dust mites and fungi was high. A reduction in quality of life was observed in 70 patients (31%). Conclusion: Allergic rhinitis can adversely affect every aspect of a patient's life, including sleep quality, mood, and daily activities. Sensitization of patients with allergic rhinitis in Northern Vietnam is similar to those in Asia, with allergy to house dust mites being common.

Материал и методы. проанализирован архивный материал, включающий 12 094 истории болезни пациентов, проходивших хирургическое лечение в пяти крупных Лор-клиниках москвы в течение 2014 г. Результаты. Установлено, что за год было проведено 659 хирургических вмешательств по удалению кисты верхнечелюстной пазухи, что составляет 34,1% от общего числа операций по поводу хронического верхнечелюстного синусита и 4,1% от общего числа хирургических вмешательств на Лор-органах. применялись следующие хирургические доступы: эндоназальный (через средний носовой ход)-в 188 (28,5%) наблюдениях, экстраназальный (через переднюю стенку пазухи)-у 454 (68,9%) пациентов, комбинированный-в 17 (2,6%) случаях. Вывод. отмечена целесообразность разработки рекомендаций по выбору оптимального хирургического доступа при кистах верхнечелюстной пазухи. Ключевые слова: киста верхнечелюстной пазухи, хронический гайморит, медицинский стандарт лечения.

The objective of the present work was to study syntopy of the large neck vessels in relation to the capsule of palatine tonsils with the use of the MRI technology. A total of 109 patients (218 palatine tonsils) presenting with chronic tonsillitis were available for the examination including 64 women and 45 men at the age varying from 15 to 54 years. All of them underwent MRI-guided vascular visualization in the paratonsillar region together with the measurements of the vessels extending to the capsule of the palatine tonsils at the level of the upper and lower poles, and also close to the mid-third of each palatine tonsil. The distance from the external carotid artery to the upper and lower poles of the palatine tonsils was found to be 17.1±1.01 mm and 10.3±0.18 mm respectively and in the mid-third the palatine tonsil 10.7±0.12 mm; the distance from the internal carotid artery to the upper and low poles of the palatine tonsil amounted to 14.5±0.84 mm and 16.8±0.77 mm respectively while that to the mid-third of the palatine tonsil was 15.3±0.07 mm. The branches of the external carotid artery feeding the palatine tonsils are the most frequent sources of bleedings; the following measurements were obtained: the maxillary artery 16.4±0.43 mm (17.4%) - the upper pole 9.6±0.02 mm (46.2%), the mid-third of the palatine tonsil 18.5±0.74 mm (29.5%) - the lower pole; the lingual artery 4.7±0.02 mm (6.8%) - the mid-third of the palatine tonsil, 6.2±0.82 mm (56.8%) - the lower pole; facial artery: 4.2±0.01 mm (0.76%) - the mid-third of the palatine tonsil; the occipital artery 25.6±0.12 mm (19%) - the upper pole; 14.8±0.11 mm (18.9%) - the mid-third of the palatine tonsil 9.56±0.12 mm (3.8%) - the lower pole; the tonsillar artery 1.88±0.01 mm (9.8%) - the upper pole; 2.51±0.01 mm (23%) - the mid-third of the palatine tonsil; 2.12±0.01 mm (11%) - the lower pole. The distance from the internal jugular vein to the capsule of the palatine tonsils in the region of the upper pole of the palatine tonsil was 28.3±1.01 mm, in the lower pole region 26.6±1.54 mm, and in the region of the mid-third of the palatine tonsil 22.7±1.24 mm. It is concluded that the results of the present study may be useful for the planning of the surgical strategy for the treatment of the patients presenting with chronic tonsillitis and for the prevention of hemorrhagic complications of tonsillectomy.
