RESUMO
The article presents an analysis of the plastic reconstructive surgery effectiveness for patients with an extended tracheal defect using an allograft based on the dura mater (DM) at the final stage of surgical treatment of laryngeal and tracheal cicatricial stenosis. The study included 20 patients with cicatricial stenosis of the larynx and trachea, who were previously performed plastic reconstructive treatment with scar tissue excision in the lumen of the respiratory tract and restoration of the supporting frame of the larynx and trachea using allografts based on costal allocartilage. The age of the patients ranged from 21 to 54 years, the duration of the disease was from 1 to 5 years. After a standard clinical and laboratory examination, with a mandatory video endoscopic examination of the larynx and trachea, multislice computed tomography of the larynx and trachea, patients underwent plastic closure of the tracheal defect using DM. Dynamic outpatient monitoring was carried out once a week for 1 month, once a month for 3 months, control examination was done 6 months after surgical treatment. The results of the study demonstrated a full-fledged social and labor rehabilitation of all 20 patients after the final stage of surgical treatment using DM, the absence of rejection reaction and migration of allo-implantation material, the preserved lumen of the larynx and trachea with a rigid supporting skeleton and the absence of anterior tracheal wall floatation. The use of DM as an additional strengthening of the anterior tracheal wall for patients with deficiency of muscular aponeurotic tissues and more than 2 cm size tracheal defect is highly effective at the final stage of surgical treatment for plastic closure of the tracheal defect.

For the purpose of decrease in intraoperative blood loss during a tonsillectomy the technique of a laser diaphanoscopy (DS) of the palatal tonsil (PT) and paratonsil space is developed. In the conditions of a transillumination of tissues of throat vessels paratonsil space which are preventively coagulated by the holmium laser are visualized. In carrying out DS of structures of a throat the 'pilot' red laser of the surgical laser LUMENIS Versa Pulse Power Suite 20W system was used. In a research there were 60 patients with chronic tonsillitis. Laser DS was carried out before tonsillectomy, at the same time 120 PT were subjected to raying. As result of the conducted research established that 60% of PT (n=72) anatomic were deeply shipped in a sidewall of a throat, 44,2% of PT (n=53) - had the expressed top pole, 0,8% of PT (n=1) - an additional segment. Also it was established that laser transillumination of paratonsil space is possible in the conditions of infiltration of fabrics isotonic physiological NaCl solution of 0,9%. Carrying out preventive coagulation of vessels of paratonsil space of Ho:YAG laser in the conditions of DS allows to reduce the volume of intraoperative blood loss to 4,17±0,37 ml that is 10,1 time less in comparison with the tonsillectomy which is carried out on traditional techniques.

The authors studied the reporting documentation of otorhinolaryngological hospitals of the city of Moscow on the surgical treatment of pharyngeal pathology in adults from 2002 to 2017. It was found that for 16 years surgical treatment of 290 362 patients with ENT-diseases was performed: 181.206 (62.4%) patients with diseases of the nose and paranasal sinuses, 24.981 (8.6%) patients with ear pathology, 60.346 (20.8%) patients with diseases of the pharynx and 23.829 (8.2%) - with diseases of the larynx. The assessment of the overall dynamics of the studied indicators was carried out on the 'trend lines'. For the considered period, the number of patients with surgical pathology of the pharynx increased by 33.2%. The proportion of tonsillectomies increased by 1.85 times to 56.5%, drainage of peritonsillar abscesses and abscesses-tonsillectomies decreased by 19%, uvulopalatoplastic increased 4.1 times, removal of neoplasms of the pharynx increased 2.2 times, adenotomies decreased by 2.4 times. Analysis of the data allowed to establish that, against the background of an ever-increasing number of surgical interventions for diseases of the pharynx in adults, a descending trend was noted only in the treatment of complicated forms of chronic tonsillitis and hypertrophy of the pharyngeal tonsil.

The objective of the present study was to optimize the treatment of patients with subglottic laryngeal stenosis. MATERIAL AND METHODS: We have examined a total of 14 patients presenting with subglottic laryngeal stenosis. The etiological factors and underlying conditions of laryngeal stenosis were the prolonged intubation in 4 patients, Wegener granulomatosis in 6 patients, and idiopathic stenosis of the larynx in 4 patients. All the patients underwent balloon dilatation with the application of the video endoscopic technique. RESULTS: The surgical treatment of all the patients made it possible to achieve the persistent expansion of the lumen of the subglottic part of the larynx, to shorten the periods of the in-patient treatment and rehabilitation of the patients. Restenosis of laryngeal lining stenting was observed in one patient presenting with Wegener's granulomatosis which was associated with the relapse of the underlying disease.

The objective of the present study was to consider the currently available methods for the diagnostics and treatment of the patients presenting with bilateral paralysis of the larynx of various etiologies. We undertook the analysis of the publications in the domestic and foreign scientific literature concerning diagnosis and treatment of bilateral paralysis of the larynx. It was found that despite the existing modern high-tech diagnostic technologies and the variety of surgical methods for the treatment of this condition, the problem of diagnostics, management, and rehabilitation of the patients suffering from bilateral paralysis of the larynx remains a serious challenge for the researchers and clinicians that requires further investigation of this pathology. For the correct and timely diagnosis of bilateral paralysis of the larynx, the comprehensive evaluation of the functional state of the neuromuscular apparatus of the larynx is necessary. The key prerequisites for the success of the surgical intervention are its timeliness and the choice of the optimal surgical modalities.

The objective of the present study was to analyze the complications of tracheostomy associated with bleeding from the brachiocephalic trunk. A total of 13 protocols of the autopsy study of the patients who had died in the intensive care unit were available for the analysis. These patients had experienced heavy external bleeding from the tracheostomy defect shortly before death. The study has demonstrated that all the victims had the tracheostomy hole localized below the level of the standard dissection of the tracheal rings. Nine patients presented with a damage to the brachiocephalic trunk while four others had a pressure injury to the blood vessels. The study included the elucidation of the possible relationship between the anthropometric characteristics of the patients and the variability of the passage of the brachiocephalic trunk in front of the trachea. The length of the neck was found to usually correlate with the length of the body and the brachiocephalic trunk to run in front of the trachea at the level of its 8th-11th rings. The results of the present study may be instrumental in reducing the risk of complications after tracheostomy.

AIM: the objective of the present study was to increase the functional effectiveness of the combined treatment of the patients presenting with bilateral laryngeal paralysis on the basis of the development of a medical diagnostic algorithm taking into consideration the peculiar etiological and pathogenic features of the clinical course of the disease. The study included 102 patients suffering from bilateral paralysis of the larynx. The duration of the disease varied from 2 months to 26 years. All the patients underwent the preoperative preparation followed by laryngoplasty surgery for unilateral myoaritenoidchordectomy. The patients who had no tracheostoma at admittance were treated by simultaneous tracheostomy and laryngoplasty. The study made it possible to identify the factors that exerted the adverse influence on the outcome of the operation, such as prolonged cannulation, a protracted course of the disease (for more than 1 year), longer periods of recovery of the external respiration function characteristics, increased duration of the hospitalization and rehabilitation periods that lasted over more than one year, and a rise in the number of the patients carrying the cannulas. Taken together, the proposed algorithm for the examination and treatment of the patients presenting with bilateral laryngeal paralysis, the early diagnostics of the disease, and the differential approach to its treatment made it possible to reduce the frequency of the immediate and long-term postoperative complication and decrease the duration of hospitalization and rehabilitation of the patients.

The problem of rehabilitation of the patients presenting with post-intubation stenosis of the larynx and trachea remains unresolved despite the development of new methods for the diagnostics and treatment of this condition. One of the indications for long-term artificial lung ventilation is the severe form of Guillaine-Barret syndrome associated with paralysis of breathing muscles, development of bulbar symptoms, and disturbances of trophic process in the skin and mucous membranes. However, prolonged (mean 26 days) artificial lung ventilation may result in the formation of many-layer stenosis of the larynx and trachea whereas disturbed trophic processes in the skin and mucous membranes coupled to inadequate innervation complicate the postoperative conditions of the patients and promote restenosis of the tracheal lumen.

Posttraumatic stenosis of the larynx, cervical and upper choracic parts of the trachea was treated surgically using biomaterial (cartilage) alloplant and hemostatic material sergisel with an antibacterial effect. Cartilage implantation into the lateral tracheal walls was made in 10 patients, creation of the lateral and anterial walls of the larynx and trachea was made in 4 patients. Short before the cartilage placing in the tissues it was packed with material sergisel. Further adequate dilatation prosthetic reconstruction of the trachea for 3-4 months with application of silicon T-tube allowed complete decanulation of 7 patients (50%) -- they have undergone plastic surgery of the anterior tracheal wall. The rest 7 patients are at the stage of dilatation of the tracheal passage with a good response to therapy. Thus, a positive treatment result of alloplant and sergisel (implant and hemostatic materials, respectively) allows us to recommend these materials for reconstructive surgery of hollow organs of the neck.
