UNLABELLED Nasal septum deviation (SD) and turbinate hypertrophy (TH) increase the resistance to respiratory airflow and may impair nasal patency. OBJECTIVE To characterize the nasal geometry of individuals with nasal obstruction secondary to SD and/or TH by means of acoustic rhinometry. METHOD This prospective study included 30 adults with complaints of nasal obstruction (NO) and SD + TH (...

Recent studies of several animal models have shown beneficial effects of probiotics against allergic responses. However, few reports have examined the effects of probiotics on allergic nasal symptoms such as sneezing and nasal obstruction in animal models of allergic rhinitis. This study evaluated the efficacy of Bifidobacterium bifidum G9-1 (BBG9-1) on antigen-induced nasal symptoms using guin...

Nasal obstruction can occur at different life stages. In early stages of life the respiratory system is still under development, maturing during the growth period. Previous studies have shown that nasal obstruction in neonatal rats alters craniofacial function. However, little is known about the effects of nasal obstruction that develops during later growth periods. The aim of this study was to...

OBJECTIVES A cross sectional study of 54 furniture factories and three control factories was conducted to investigate the relation between subjective and objective nasal obstruction and exposure to wood dust. METHODS Acoustic rhinometry was performed on 161 woodworkers and 19 controls. For each person, four measuring rounds were performed: before work, after 4 hours of work, and after 7 hours...

nasal obstruction) were recorded before challenge and every 15 minutes after challenge initiation. For the evaluation of nasal obstruction, we used visual analog scales (VASs); subjects marked a site on a 10-cm line corresponding to the symptom severity on which absence of symptoms was designated as 0 and worst imaginable symptom as 10. PIFR was measured using an In-check flow meter and nasal r...

IMPORTANCE Nasal obstruction is common in children and difficult to quantify objectively. Symptom quantification is paramount for surgical and medical decision making. Acoustic rhinometry is a relatively new technique aimed at the objective assessment of nasal obstruction. There is no standardized method for the objective assessment of the pediatric nasal airway. OBJECTIVE To explore the corr...

OBJECTIVE To evaluate the impact of nasal surgery alone on quality of life (QOL) in patients with obstructive sleep apnea and nasal obstruction using generic and disease-specific QOL questionnaires. DESIGN Prospective, longitudinal cohort study. PATIENTS Fifty-one consecutive patients with obstructive sleep apnea (50 men and 1 woman; mean age, 39 years; mean [SD] apnea-hypopnea index, 37.4 ...

Subjective nasal obstruction is a common chronic complaint caused by mucosal disease, skeletal abnormality or a combination of both. The challenge is to determine the main cause and to decide whether the intervention should be medical or surgical. Diagnosis is done by a combination of rhinoscopy, subjective and objective assessments of nasal obstruction. Rhinomanometry measures the nasal airway...

H1 antihistamines constitute one of the main references for the treatment of allergic rhinitis. Classically, these drugs have been considered effective in controlling sneezing, rhinorrhea and itching, though they have not been regarded as particularly effective in application to nasal obstruction. The most recent studies, involving second-generation H1 antihistamines (desloratadine, fexofenadin...
