Современный научно-технический прогресс повысил запросы эстетической медицины и дал бурное развитие дентальной имплантации, совершенствованию хирурги-ческих методов, расширяющих возможности внутрикост-ной имплантации больным с отсутствием зубов на верх-ней челюсти в силу врожденных анатомических особен-ностей или вторичной адентии [1].Согласно данным статистики, большую часть боль-ных с частичной или полной адентией верхней челюсти составляют больные с одонтогенным перфоративным верхнечелюстным синуситом (ОПВС) [1].ОПВС является сложным патологическим процес-сом, характеризующимся как хроническое воспаление верхнечелюстной пазухи, вызванное инфекцией из очагов острого или хронического воспаления в зубочелюстной системе (периодонтиты, периоститы, остеомиелиты, на-гноившиеся кисты верхней челюсти) с наличием стойкой сформированной ороантральной фистулы [2].В последние годы проблема лечения ОПВС все чаще поднимается в медицинском научном сообществе. Она требует междисциплинарного подхода для оказания ква-лифицированной медицинской помощи: тесного сотруд- Цель работы -анализ различных методов пластики ороантрального свища слизистым лоскутом и с использованием остеопластических материалов, оценка их преимуществ и недостатков по данным литературы и интернет-источников. Представлены характеристики идеального материала для пластики ороантрального свища и условия для ее проведения.
Ключевые слова: одонтогенный верхнечелюстной синусит, ороантральный свищ, пластика ороантрального свища, остео-пластические материалыThe objective of the present study was the comparative analysis of various methods for the plastic correction of the oroantral fistula with the use of the mucosal flap and the osteoplastic materials based on the data from the literature and on-line publications. The characteristics of an ideal material for the plastic correction of the oroantral fistula and the conditions for carrying out this surgery are discussed.
This study focuses on the clinical symptoms of inflammatory and destructive lesions of the facial skeletal bones as a long-term complication of coronavirus disease-2019 (COVID-19). The most common symptom of COVID-19 is thrombosis. Many scientists have noted that the main target of COVID-19 is the lungs with varying damage severity in the form of pneumonia. Acute cerebrovascular accidents and coronary pathology have become the most common causes of lethal outcomes in young people. Clinically, in patients with COVID-19, both obvious thrombotic complications were recorded with large thrombi detection (not only in the veins and pulmonary arteries, but also in the heart and vessels of the brain, kidneys, and liver), as well as signs of thrombosis at the microcirculatory level, which is quite difficult to establish in vivo. The diagnostics, treatment, and follow-up of a patient with COVID-19 history and complications that arose in the maxillofacial region were conducted in the Department of Maxillofacial Surgery of Clinical Hospital. Upon admission, the patient was diagnosed with chronic osteomyelitis of the upper jaw on the right, chronic right-sided maxilloethmoidal sinusitis, mucous membrane defect on the right hard palate, oroantral fistula on the right, and keratitis of the right eye. During the inpatient treatment, multicomponent therapy was performed. During the therapy, a general condition and local status improvement of the patient was noted.
CONCLUSIONS: The clinical cases indicate that the course of COVID-19 is characterized by late complications in the maxillofacial region in the form of damaged vessels that extend from the а. maxillaris trunk in the pterygopalatine fossa region.
The trophic disorder was slowly progressive and irreversible. The clinical and radiological presentation showed no clearly defined boundaries of bone necrosis of the facial middle zone. Low tissue regeneration was noteworthy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
