OBJECTIVE To investigate diagnostic test accuracy (DTA) of different tests for obstructive sleep apnea (OSA) compared to polysomnography (PSG) in children. METHODS We performed a systematic review according to DTA criteria published by the Cochrane Collaboration. Studies that compared any possible diagnostic test with PSG for diagnosing OSA were considered. Study quality assessment was conduc...

BACKGROUND Recently, it has been reported that nasal cytology in light microscopy can identify biofilms, which appear as cyan-stained "Infectious Spots". We assessed by the same method and in the same population, the presence of biofilms in different nasal disorders, and estimated if a correlation with the functional grade of obstruction existed. METHODS Subjects suffering from different nasa...

Correlations between breathing mode and craniofacial morphology were investigated in 47 children at the ages of 6-15 years (average, 9.9 years). Apart from history and clinical examination, nasal endoscopy, rhinomanometry and measurements of cephalometric radiographs were included in the analysis. After separating the patients into a "normal face" group and a "long face" group by measuring the ...

OBJECTIVE To study the relation between exposure and nasal function in woodwork teachers. METHODS 39 selected woodwork teachers employed full time and 32 control subjects (other school personnel) were examined at the beginning and at the end of a working week with symptom rating, nose and throat inspection, rhinomanometry, nasal mucociliary clearance test, and a smell identification test. Dur...

A reliable and comprehensive assessment of nasal breathing is problematic and still a common issue in rhinosurgery. Impairments of nasal breathing need an objective approach. In this regard, currently rhinomanometry is the only standard diagnostic tool available but has various limitations. However, in the last decade, computational fluid dynamics (CFD) has become a promising method in facing t...

OBJECTIVES The purpose is to investigate effect of septoplasty and widened nasal patency on voice quality. METHODS Fifty patients who undergone septoplasty were included in the study. Thirty-three people who had similar age and distribution were enrolled as control group. Before and 1 and 3 months after surgery, anterior rhinomanometry, voice analysis by Multi-Dimensional Voice Program, and s...

BACKGROUND Nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. This study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry. METHODS Fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. Objective...

Factors influencing nasal versus oral breathing in asthmatics are not well understood. The current authors hypothesised that asthmatic subjects have enhanced perception of nasal threshold loads, and switch from nasal to oral breathing at a lower load than healthy subjects. In total, 15 mild asthmatic and 20 healthy control subjects breathed nasally via an inspiratory threshold loading device. N...

OBJECTIVE To investigate effects of the nose dilating devices on nasal anatomy and breathing in healthy subjects. MATERIALS AND METHODS 27 healthy subjects were tested when using the Breathe Right nasal strip or the Nozovent dilator. Posterior rhinomanometry, acoustic rhinometry, and a subjective evaluation were used as methods. RESULTS Both devices significantly increased the minimum cross...
