Background. Removal of calculi in salivary stone disease is one of the urgent problems of maxillofacial surgery and surgical dentistry due to the complexity of the manipulation, the trauma of the technique and the frequent development of complications.
Aim. Improvement of the treatment results of patients with salivary stone disease by using our developed method of minimally invasive removal of calculi located in any part of the excretory duct of the submandibular and/or parotid salivary glands, under constant ultrasound visualization of the intervention.
Material and methods. The study included patients diagnosed with salivary stone disease (10 people: 9 male and 1 female aged 1850 years, mean age 44.21.25 years). The methodology was as follows. An ultrasonic sensor was brought in from the side of the skin, and the location of the calculus in the gland duct was determined. Next, a needle with a diameter of 0.3 cm with a mandrin was inserted percutaneously through a puncture into the duct of the salivary gland to the distal surface of the calculus, and it was advanced with the help of a needle as far as possible towards the mouth of the excretory duct. Then the needle was removed, leaving a mandrel in the duct, with which the calculus was fixed in a new position. After bougienage of the excretory duct, Dormias basket was introduced into it, and the calculus was captured and removed. The manipulations were performed under constant ultrasound imaging.
Results. The use of the technique developed by us for minimally invasive removal of a calculus with a diameter of up to 5 mm, located in any part of the excretory duct of the submandibular and/or parotid salivary glands, under constant ultrasound visualization of the intervention course, made it possible to achieve a positive result in all 10 patients included in clinical observations.
Conclusion. The minimally invasive technique for removing calculi from the excretory ducts of the salivary glands under constant ultrasound imaging developed by us makes it possible to facilitate manipulation, its visibility and accuracy, as well as atraumaticity and prevention of complications.
In the clinic of purulent maxillofacial surgery, one of the most acute problems is odontogenic phlegmons arising from the spread of pathogenic origin from the focus of chronic infection of the so-called "causal" tooth, which is associated with the severity of the purulent process itself, the rapidity of its spread to neighboring cellular spaces, a high risk of severe complications and frequent death]. The problem under consideration has not only medical, but also important socio-economic significance. The aim of the work was to study the prevalence of odontogenic phlegmon in the Republic of Uzbekistan to identify the main trends in the development and course of this pathology. Materials and methods. 845 case histories of patients with odontogenic phlegmon hospitalized in the hospital of maxillofacial surgery of the Department of adult maxillofacial surgery of the Tashkent State Dental Institute in the period from 2019 to 2021 were studied. Statistical processing of the research results was carried out using Microsoft Excel 10 application programs and the STATISTICA for Windows 6.0 statistical package (Statsoft, USA) by the method of variational statistics using the Student's parametric criterion. We also used a statistical research method – Pearson Chi-squared. Results of the study. There was an increase in the number of patients with odontogenic phlegmon, among whom residents of the districts of the Republic of Uzbekistan prevailed and were most often found among people of working age. The odontogenic "cause" in most cases were the molars of the lower jaw. The structure of morbidity was dominated by odontogenic phlegmons of one cellular space. Most of the hospitalized patients, bypassing the pre-hospital stage, went to the hospital on their own. Findings. Given the increase in the number of patients with odontogenic phlegmon, the issues of their prevention and effective treatment remain relevant.
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.
