[Antibacterial therapy for acute streptococcal tonsillopharyngitis: results of a randomized comparative clinical trial with amoxicillin + clavulanic acid EXPRESS].

Background: Acute tonsillopharyngitis is one of the most common types of respiratory tract infections. In case of bacterial etiologies of the disease, penicillin antibiotics are prescribed, in particular amoxicillin + clavulanic acid. Dispersible forms of antibiotics have a number of advantages over film-coated tablets and are characterized by better pharmacokinetic parameters that increase the effectiveness and safety of treatment, as well as patient compliance.

[Vocal fold polyps: modern possibilities of laser surgery in comparison with the use of cold microinstruments].

Objective: To perform a comparative analysis of phonosurgical interventions, which were made using a 445 nm semiconductor laser or cold microinstrumentation in patients with «vocal fold polyp» diagnosis.

Material And Methods: The number of surgical interventions equal 30 regarding vocal fold polyp was done in otorhinolaryngology clinic of Pavlov First State Medical University of St. Petersburg in the period from September 2021 yr.

Safety of high-power short pulse single spot diode laser stapedotomy: an experimental animal study.

Background: We present a new method of diode laser stapedoplasty - high-power short-pulse mode with preliminary carbonization of the waveguide and a single spot of laser ablation.

Aims/objective: The aim of our research is the safety evaluation of presented mode 0.98 µm diode laser cochleostomy in guinea pigs.

[Experimental research of the diode 970 nm laser thermal effect in order to develop a method for reduction of nasal swell body].

Objective: To evaluate the thermal effects of a 970 nm diode laser and select the modes necessary for the safe and effective use of this laser to reduce the nasal septum elevation (NSB) in volume in vitro.

Material And Methods: Laser exposure was carried out through a quartz fiber with a diameter of 400 μm in a continuous contact mode at a power from 2 W to 10 W with a step of 2 W. Three linear cuts 1 cm long were applied to the specimens.

Using thermal effect of 970 nm diode laser to reduce nasal swell body.

In recent decades, semiconductor lasers have been successfully used in rhinology. However, their usage in the reduction of the nasal swell body (NSB) is barely studied. Our research aimed to conduct an experimental selection of the laser exposure mode in the NSB zone using a 970 nm diode laser for safe and effective NSB reduction.

[The low-invasive treatment of laryngotrachealstenoses].

The objective of the present study was to evaluate the effectiveness and safety of balloonlaryngotracheoplasty for the treatment of laryngeal and tracheal stenosis We undertook the analysis of the case histories of the patients presenting withlaryngotracheal stenosis who had undergone balloonlaryngotracheoplasty during the period from October 2013 till February 2016. A total of 21 histories of the patients (6 men and 15 women) were available for the investigation. Most laryngotrachealstenoses that occurred in 18 (85.

[The choice of parameters for the laser application in ENT surgery].

The authors present the results and describe the methods of the experimental studies aimed at the evaluation of the biological effects of laser-assisted treatment of ENT pathologies at the wavelengths of 810 nm, 980 nm, and 1470 nm in comparison with the results obtained with the use of a radiofrequency scalpel in biological tissues having different optical and mechanical properties.Special emphasis is placed on the peculiarities of the action of laser irradiation and healing of radiation-induced wounds depending on the treatment regimens, viz. contact, remote, pulsed and continuous ones.

[The potential of photodynamic therapy for the treatment of recurrent respiratory papillomatosis].

The problem of recurrent respiratory papillomatosis (RRP) thus far remains unresolved despite a large number of surgical and conservative methods proposed to address it. Photodynamic therapy is an up-to-date tool for the treatment of various neoplasms based on the interaction between the light and a photosensitizing agent (PA) that gives rise to active oxygen species and causes the death of cells. The potential of photodynamic therapy for the treatment of recurrent respiratory papillomatosis remains to be elucidated.

Zeneker's diverticulum (pharyngeal diverticulum) is a pathological sac-like protrusion of the mucous membrane at the posterior nasopharyngeal wall. Surgical operation is the principal method for the treatment of this rather rare disease. In the present paper, two cases of its successful management by means of laser-assisted endoscopic diverticulotomy are described.
