The use of pulse transit time in diagnostics of sleep-disordered breathing in children.

Introduction: Sleep is the physiological state of the body where proper morphology and duration are indispensable for human functions throughout both, physical and mental spheres. Disordered breathing during sleep impairs its morphology and results in major disorders in any age group. Adverse effects of Obstructive Sleep Apnea Syndrome in children and poor availability of centers offering children's polysomnography call for a reliable and easily accessible screening method.

Erbium:Yttrium Aluminum Garnet (Er:YAG) Laser: A Minimally Invasive Treatment Method in Selected Patients with Impaired Breathing During Sleep-The Assessment of Treatment Effectiveness After 4 Years.

The aim of this study was to assess the long-term outcomes of nonablative Er:YAG laser treatment for snoring. Nonablative Er:YAG laser treatment has been shown to improve subjective quality of sleep without serious adverse effects, but long-term data are lacking. Twenty-four patients with snoring problems due to soft palate hypertrophy were treated with three treatment procedures with Er:YAG laser performed at 2-week intervals.

Analysis of the Effectiveness of Arytenoidectomy and Posterior Cordectomy with the Use of CFD Airflow Measurements in Patients with BVFP: A Retrospective Study.

Purpose: Bilateral vocal fold paralysis (BVFP) is a rare larynx disease manifested by dyspnea, which often requires surgical treatment. The aim of the study is to determine the effectiveness of unilateral arytenoidectomy with posterior cordectomy in the treatment of BVFP using the computational fluid dynamics (CFD) method.

Methods: This study included 33 patients with BVFP who underwent unilateral laser arytenoidectomy with posterior cordectomy.

Tracking of the biochemical changes upon pleomorphic adenoma progression using vibrational microspectroscopy.

Head and neck tumors can be very challenging to treat because of the risk of problems or complications after surgery. Therefore, prompt and accurate diagnosis is extremely important to drive appropriate treatment decisions, which may reduce the chance of recurrence. This paper presents the original research exploring the feasibility of Fourier transform infrared (FT-IR) and Raman spectroscopy (RS) methods to investigate biochemical alterations upon the development of the pleomorphic adenoma.

Minimally invasive erbium laser treatment for selected snorers.

The aim of this paper is to present our results and experience in the treatment of snoring using the non-ablative Erbium: Yttrium Aluminum Garnet (Er:YAG) laser. Twenty-four patients (18 male and 6 female) with snoring problems due to soft palate hypertrophy were treated with 3 treatment procedures with Er:YAG 2940-nm laser (long pulse mode, 10 Hz, fluence 1.8-2.

Computational fluid dynamics in the assessment of patients' postoperative status after glottis-widening surgery.

Background: Computational fluid dynamics (CFD), a rapidly developing instrument with a number of practical applications, allows calculation and visualization of the changing parameters of airflow in the upper respiratory tract.

Objectives: The aim of this study was to demonstrate the advantages of CFD as an instrument for noninvasive tests of the larynx in patients who had undergone surgical treatment due to bilateral vocal fold paralysis.

Material And Methods: Surface measurements of the glottic space were made during maximum adduction of the vocal folds.
