BACKGROUND Nasal airway obstruction is a common complaint of patients presenting to otolaryngology clinics and can be caused by a variety of anatomic factors. A number of advances in the surgical management of nasal airway obstruction have been made over the last century. The objective of this article is to provide descriptions of the surgical procedures used to augment specific anatomic devia...

Nasal exposure to the mixture of microbial extracts (MME) after ablactation enhanced airway resistance of newborn mice to Streptococcus pneumoniae (J Physiol Lung Cell Mol Physiol 298: L67, 2010). The present study was addressed to elucidate effective factors responsible for the enhanced innate resistance in the airway of MME-exposed newborn mice. MME exposure significantly increased the amount...

Methods Total nasal symptom score (TNSS), NW and turbinate biopsy specimens were obtained from 36 AR and 20 NAR patients. Atopic patients had positive skin prick test to D.pteronyssinus (35/97%) and L.perenne (18/50%) extracts from Hollister-Stier. Total and differential cell counts were evaluated by a quantitative method of nasal cytology; albumin and IL-8 concentrations were determined in the...

Cleft lip and palate (CLP) affects the dentoalveolar and nasolabial facial regions. Internal and external nasal dysmorphology may persist in individuals born with CLP despite surgical interventions. 7-18 year old individuals born with unilateral and bilateral CLP (n = 50) were retrospectively assessed using cone beam computed tomography. Anterior, middle, and posterior nasal airway volumes were...

An association between mouth breathing during sleep and increased propensity for upper airway collapse is well documented, but the effect of treatment for nasal obstruction on mouth breathing during sleep and simultaneous obstructive sleep apnoea (OSA) severity has not been described previously. A randomised single blind placebo- and sham-controlled crossover study of treatment (topical deconge...

treacher collin’s syndrome (tcs) is a rare inherited condition characterized by bilateral and symmetric abnormalities of structures within the first and second bronchial arches. patients with tcs present a serious problem to anesthetists maintaining their airway as upper airway obstruction and difficult tracheal intubation due to severe facial deformity. because of retrognathia, airway manageme...

background: indian tea industry workers are exposed to various exposures at their workplace. objective: to investigate the respiratory health of indian tea industry workers. methods: we administered a respiratory questionnaire to and measured lung function in workers of 34 tea gardens and 46 tea factories. we used correlation matrices to test the association between their respiratory symptoms a...

BACKGROUND Nasal continuous positive airway pressure is frequently used to support preterm infants with respiratory distress syndrome. Little is known about the hemodynamic changes that occur, particularly during the weaning phase when lung compliance has improved and most of the airway pressure can be transmitted to the heart and major blood vessels. METHODS We conducted a prospective study ...

1. Covering facemasks or nasal cannulae with surgical facemasks generally improved percentage of inspired oxygen (FiO2) but at a risk of increased CO2 rebreathing when a low oxygen flow rate was used. 2. We recommend that at least 5 L/min of oxygen be used for nasal cannula and at least 6 L/min of oxygen be used for facemask when these devices are covered with a surgical facemask. 3. Using a co...

In a selected group of rhinitis patients with an IgE-mediated allergy to house dust mites the nasal response to insufflation of histamine chloride, methacholine and phentolamine was demonstrated to be higher than in a control group. With the methods used histamine chloride was better at discriminating between healthy subjects and patients than methacholine or phentolamine. This discrimination w...
