A report on the primary application of the modern technique of plastic removal of stricture of the Stenonic duct. A clinical case of surgical intervention in the localization of stricture and salivary stone is considered. The analysis of the patient\'s medical history, ultrasound diagnostics, multispiral computed tomography of the maxillofacial region was carried out. Based on the results of the examination, the choice of the surgical intervention technique was made.
Сообщение о первичном применении современной методики пластического устранения стриктуры стенонова протока. Рассмотрен клинический случай проведения оперативного вмешательства при локализации стриктуры и слюнного камня. Проведены анализ истории заболевания пациента, ультразвуковая диагностика, мультиспиральная компьютерная томография челюстно-лицевой области. На основании результатов обследования определена методика оперативного вмешательства.

To define SEM characteristics that may aid identification of sialoliths.
Two sialoliths from modern patients affected by sialadenitis.
Samples were coated with silver and subjected to scanning electron microscopy using an energy-dispersive X-ray spectroscopy detector. Samples were then sectioned to permit study of the internal structure.
Sialoliths show an external smooth surface with no distinctive features. Internal structures consist of a distinctive aggregate of coarse granules of different sizes surrounded by a lamellar coat. Elemental composition consists of carbon, phosphate, calcium and oxygen, with traces of magnesium. The proportion of these elements differs between the core and the surface.
Although elemental composition is not specific, SEM analyses of sialoliths greatly differ from those of sesamoid bones, gallstones and nephroliths. Therefore, SEM analysis constitutes a useful tool for the precise identification of small calcified structures recovered during archaeological excavations.
Precise identification of calcified structures may provide information about nutritional and/or pathological aspects of past individuals.
Sialoliths are less common than other types of calcifications, and only two cases were analyzed in this study.
SEM technology should be applied to identify the etiology of all minute calcified remains recovered during archaeological excavations of burial sites.
