conclusions in this case, after failure of awake fiberoptic intubation, awake direct laryngoscopy and blind nasal intubation, finally awake nasal intubation in sitting position, using fiberoptic led to success. case presentation the present case discusses a patient with severe deformity of mandible that was admitted for correction with free-flap. the following intubation techniques were used fo...

Subjective nasal obstruction is common among users of continuous positive airway pressure (CPAP). The aim of this study was to measure the acute effect of CPAP on nasal resistance and nasal symptoms in awake normal subjects. Twenty-four healthy CPAP-naive adults [8 men, 16 women; mean age 30 yr (SD 14)] underwent a randomized controlled crossover study comparing nasal CPAP (8 cmH(2)O) for 6 h o...

Computerized rhinomanometry with the practical software programmes is used widely as a research tool to evaluate objectively nasal air flow and resistance parameters, while the increase of its clinical application may be facilitated by further standardization of the method. The aim of the study was to determine the total nasal resistance normal values in healthy adult population using a method ...

The relationship between nasal obstruction and craniofacial growth is unclear. The literature indicates that upper-airway compromise produces chronic mouth breathing, especially in the dolichocephalic (narrow-faced) child. It has been shown that a greater tendency exists toward the skeletal pattern associated with long face syndrome in dolichocephalic head types. Therefore, it becomes difficult...

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 a...

PURPOSE Nasal polyposis is a chronic inflammatory disease of the upper airways often associated with asthma and characterized by markedly increased numbers of eosinophils, Th2 type lymphocytes, fibroblasts, goblet cells and mast cells. Previous studies have shown elevated levels of thymic stromal lymphopoietin (TSLP) in atopic diseases like asthma, atopic dermatitis and mainly in animal models ...

RATIONALE Nitric oxide (NO) is present at higher concentrations in the nasal cavity than in the lower airway, and at even higher concentrations within the paranasal sinuses proper. When the paranasal sinus ostia are patent, acoustic activity produced by vocalization with closed lips (humming) promotes mixing of sinus with nasal gases, producing a further increase in nasal NO. We wished to evalu...

BACKGROUND Few population-based studies have assessed the prevalence and the risk factors of non-allergic rhinitis (NAR) in comparison to allergic rhinitis (AR). Moreover, epidemiologic data on rhinitis in the elderly subjects and in southern Europe are scarce. OBJECTIVE This study aimed at estimating the prevalence and at comparing the risk factor distribution of AR and NAR in a general popu...

Three main types of inflammatory Non-Allergic Rhinitis (NAR) have been defined: NAR infiltrated by eosinophils (NARES), by mast cells (NARMA), and by neutrophils (NARNE). A new particular type has been characterized with current infiltration by eosinophils and mast cells (NARESMA). The aim of this study is to evaluate the clinical and functional characteristics in patients with NARES, NARMA, NA...

BACKGROUND Unrestrained plethysmography has been used to monitor bronchoconstriction because of its ease of use and ability to measure airway responsiveness in conscious animals. However, its reliability remains controversial. OBJECTIVE To investigate if unrestrained plethysmography could provide a valid interpretation of airway responsiveness in allergic BALB/c mice. METHODS Ovalbumin sens...
