Indications for the Use of Sialoendoscopy in Sialolithiasis.

The aim of the study is to determine indications for the use of sialoendoscopy in the diagnosis and treatment of sialolithiasis. MATERIALS AND METHODS: The study involved 115 patients with sialolithiasis, who underwent cone beam computed tomography, ultrasound diagnosis of the salivary glands, and sialoendoscopy, in addition to the standard general clinical examination. RESULTS: Sialoendoscopy makes it possible to detect a stone, determine its shape, relative size, mobility, and assess the condition of the salivary ducts. It is impossible to obtain this information by other methods, though it is very important for treatment decision making. The design of the sialoscope and its special instruments make it possible to proceed with sialolith extraction immediately after detecting it. CONCLUSION: The absolute indication for the use of sialoendoscopy is mobile calculi less than 5 mm in diameter (L1 according to F. Marchal's LSD classification). In case of immobile sialoliths less than 4-8 mm in size, located in the main duct (L2), endoscopy should be used as a method supplementary to ductotomy. When sialoliths are located in the distal parts behind the areas of bending or stricture (L3a and L3b), the use of endoscopy is not indicated.

The endosialoscopy method has opened the possibility of atraumatic removal the stones from large salivary glands. The advantage of endosialoscopic extraction of sialolithes over traditional methods of ductotomy and removal of the gland does not cause doubts, but the indications for its use are not yet clearly defined. This study analyzes the results of 75 surgical endoscopic interventions for salivary stones extraction.

[Effect of a gel based on recombinant human angiogenin on the healing of donor palate wounds]. / Vliianie gelia na osnove rekombinantnogo angiogenina cheloveka na zazhivlenie donorskikh ran tverdogo neba.

The aim of the study was to study the effect of the gel on the basis of recombinant human angiogenin on the rate of regeneration of donor palatal wounds. The study involved 20 patients (8 men and 12 women) aged 32 to 55 years. Patients were divided into two groups: the 1st group is a study group (n=10), whose patients in the postoperative period used a gel based on recombinant human angiogenin, the 2nd group is a control group (n=10) in which a gel based on recombinant human angiogenin was not used. Patients in both study groups underwent vestibuloplasty with simultaneous plasty of the attached keratinized gingiva with a free gingival graft from the area of the hard palate. The operations were carried out at the stage of disclosing dental implants, simultaneously with the installation of healing abatements or 4 weeks before dental implantation. For histological examination, tissue samples were obtained from the region of the edge of the donor's wounds of the palate at the 7th and 14th days after surgery. As a result of the study, significant differences were found in the comparison groups when assessing the processes of inflammation, angiogenesis and epithelization. The local application of the gel containing recombinant human angiogenin resulted in a rapid decrease in the intensity of inflammation in lamina propria mucosae and a significant decrease in the bulk density of cell infiltrates, accelerating regeneration. This is primarily due to the stimulation of the development of epidermal growth factor (EGF), vascular endothelial growth factor (VEGF) and increased blood supply to the affected area, as well as an increase in the proportion of fibroblasts. The most important observation was the increase in the rate of epithelialization of donor wounds of the hard palate.

[General anesthesia and intensive care for patients surgically treated for deep neck odontogenic infections]. / Osobennosti anesteziologicheskogo obespecheniia i intensivnoi terapii bol'nykh pri khirurgicheskom lechenii odontogennykh flegmon dna polosti rta.

The study objectives were to determine the significance of deep neck odontogenic infections severity to predict the postoperative morbidity. Observational study was conducted in 2014-2015. A continuous sample of 38 patients who were urgently hospitalized in the Novosibirsk Regional Clinical Hospital with deep neck odontogenic infections and operated on the day of hospitalization was analyzed. SAPS scale rates correlated positively with the duration of the artificial lungs ventilation (ALV). The positive balance of the introduced and withdrawn liquid in the first day of the postoperative period is associated with the ALV duration, which requires accurate dosing of the infusion volumes. The described protocol of perioperative care significantly decreases morbidity in patients with deep neck odontogenic infections.

[Endoscopic surgery in the treatment of patients with extensive odontogenic cysts]. / Éndoskopicheskaia khirurgiia pri lechenii bol'nykh s obshirnymi odontogennymi kistami cheliustei.

The aim of the study was the assessment of effectiveness of endoscopic techniques in the treatment of extensive odontogenic cysts. Endosurgery for diagnostic and therapeutic purposes was used in 67 patients with odontogenic cysts of the jaws: 23 follicular cysts, 19 radicular cysts, 6 residual cysts, and 19 keratokists. The results prove that the developed methods of endovideosurgery of odontogenic cysts have low invasiveness, provide an optimal healing of bone tissue and reduce postoperative complications.

[The experience of submental intubation for severe maxillofacial injuries]. / Opyt submental'noi intubatsii trakhei pri tyazhelykh chelyustno-litsevykh povrezhdeniyakh.

Oral and nasal routes for intubation are often not feasible in maxillofacial fractures. The paper presents our experience of midline and paramedial approaches for submental intubation in the airway management of facial trauma patients. The prospective study included 47 patients with maxillofacial trauma in whom submental orotracheal intubation was performed in 2005-2014. When using midline approach the tube does not always accurately fit into the mandibular lingual groove creating an inconvenience for the surgeon. By paramesial approach the working conditions for the surgeon were the most comfortable. The average duration of the procedure was 5-6 minutes. At the end of the surgery the tube was reversed, the submental wound was stitched, patients were extubated (10 of them were extubated through the submental approach). Eight patients required short-term post-operative mechanical ventilation. In all patients the submental intubation allowed simultaneous reduction and fixation of fractures and intraoperative control of the dental occlusion without interference from the tube during the operation. There were no significant operative or postoperative complications. Submental intubation is a simple, secure and effective procedure for operative airway control in maxillofacial traumas. It is an attractive alternative to tracheotomy in the surgical management of selected cases of maxillofacial trauma.
