introduction: chronic nasal obstruction due to adenoid hypertrophy is a very common disorder. although the clinical assessment of adenoid hypertrophy is essential, its real value in young children is difficult to evaluate. the purpose of this prospective study was to validate a simple clinical score to predict the severity of adenoid obstruction and to evaluate the relationship between this met...

INTRODUCTION Nocturnal enuresis (NE) and obstructive sleep apnoea-hypopnoea syndrome (OSAHS) are common problems during childhood, and population studies have reported a significant correlation between them. This study aimed to assess whether habitual snoring, mouth breathing and daytime sleepiness are associated with increased incidence of NE in children with OSAHS. MATERIAL AND METHODS Poly...

BACKGROUND Nasal highflow (NHF) provides a warmed and humidified air stream up to 60 L/min. Recent data demonstrated a positive effect in patients with acute hypoxemic respiratory failure, especially when caused by pneumonia. Preliminary data show a decrease in hypercapnia in patients with COPD. Therefore, NHF should be evaluated as a new ventilatory support device. This study was conducted to ...

BACKGROUND A high flow of air applied by large bore nasal cannulae has been suggested to improve symptoms of chronic respiratory insufficiency. In pediatric patients, nasal high-flow (nHF) ventilation was similarly effective compared to noninvasive ventilation with a face mask. OBJECTIVES The aim of this study was to describe changes in respiratory parameters. METHODS We measured pressure a...

BACKGROUND The human respiratory airway undergoes dramatic growth during infancy and childhood, which induces substantial variability in air flow pattern and particle deposition. However, deposition studies have typically focused on adult subjects, the results of which cannot be readily extrapolated to children. We developed models to quantify the growth of human nasal-laryngeal airways at earl...

BACKGROUND Respiratory rate is an important measurement in patient care, but accurate measurement is often difficult. We have developed a simple non-invasive device to measure respiratory movements in clinical circumstances, with minimal interference with the patient. We investigated respiratory patterns in patients receiving postoperative morphine analgesia to assess the capacity of the device...

Several studies showed that nasal airway is an active component of the respiratory system. Clinical data suggest that nasal obstruction causes episodes of obstructive apnea or hypopnea. In the present study, a possible influence of breathing through the nose on genioglossus muscle (GG, dilator of upper airway) reactivity to hypoxic activation was studied. Two groups of 20-30 years and 41-55 yea...

STUDY OBJECTIVES Nasal prongs (NPs), when used to assess nasal flow, can result in dramatic increases in nasal airflow resistance (NR). The aim of this study was to investigate whether the NP-induced increases in NR could be corrected by the simultaneous use of an internal nasal dilator (ND). DESIGN NR was estimated by posterior rhinomanometry, in the basal state (NRb), and while breathing wi...

Objectives: The aim of the present study was to analyze the recovery rate of symptoms in patients with adenoid hypertrophy and investigate the role of nasal pathologies, allergy and gastroesophageal reflux (GER) as the reason of failure in patients with persistent symptoms. Patients and Methods: Patients undergoing adenoidectomy were enrolled in this study. There were 58 males and 42 females, a...

Nasal breathing is a requirement for proper growth and development of the craniofacial complex. Inadequacy of the nasal airway from obstruction such as from nasal septal deviation (NSD) can affect craniofacial development. Further investigation of the possibility of rapid maxillary expansion (RME) correcting NSD would be valuable, considering the undesirable sequelae of NSD on nasal breathing, ...
