INTRODUCTION: Nasal obstruction is a frequent complaint in otorhinolaryngology outpatient clinics, and nasal valve incompetence is the cause in most cases. Scientific publications describing surgical techniques on the upper and lower lateral cartilages to improve the nasal valve are also quite frequent. Relatively few authors currently describe surgical procedures in the piriform aperture for nasal valve augmentation. We describe the surgical technique called pyriform plasty and evaluate its effectiveness subjectively through the NOSE questionnaire and objectively through the rhinomanometry evaluation...

The planning of experimental studies for evaluation of nasal airflow is particularly challenging given the difficulty in obtaining objective measurements in vivo. Although standard rhinomanometry and acoustic rhinometry are the most widely used diagnostic tools for evaluation of nasal airflow, they provide only a global measurement of nasal dynamics, without temporal or spatial details. Furthermore, the numerical simulation of nasal airflow as computational fluid dynamics technology is not validated. Unfortunately, to date, there are no available diagnostic tools to objectively evaluate the geometry of the nasal cavities and to measure nasal resistance and the degree of nasal obstruction, which is of utmost importance for surgical planning...

BACKGROUND: This study evaluated the efficacy of rhinophototherapy in patients with chronic rhinosinusitis (CRS) without nasal polyps. METHOD: In this randomized double-blind, placebo-controlled trial, CRS patients (n=50) received either mixed visible and ultraviolet (UVA and UVB) light source application (mUV/VIS) or visible light alone that served as placebo. Both groups were treated for 3 weeks. RESULTS: Results in the rhinophototherapy and placebo group were not significantly different and failed to reduce patient-reported outcomes measures (Rhinosinusits Disability Index, Visual Analogic Scale of symptom severity) and objective scores (rhinomanometry, olfactory thresholds, nasal Nitic Oxide concentrations), immediately and one month after treatment...

BACKGROUND: Several correlations between morphological and/or positional alterations of the jaws and respiratory functional impairments have been reported. Nasal airway obstruction represents a critical issue with no clearly defined gold standard as for its measurement. Rhinomanometry was adopted by multiple Authors to evaluate whether patients with malocclusion developed respiratory functional changes after an orthodontic-surgical treatment. However, there are contrasting findings in the literature regarding the possibility of improving the respiratory function by means of surgically-assisted rapid palatal expansion (SARPE) or bimaxillary repositioning of the bony bases...

Allergic inflammation in the upper airways represents a wide-spread health issue: Little is known about whether it increases sensitivity to airborne chemicals thereby challenging established exposure limits that neglect such differences in susceptibility. To investigate the role of pre-existing allergic inflammation, 19 subjects with seasonal allergic rhinitis (SAR) and 18 control subjects with low risk of sensitization were exposed for 4h to ammonia in two concentrations (cross-over design): 2.5ppm (odor threshold) and 0-40ppm (occupational exposure limit: 20ppm TWA)...

Mite allergy causes significant socioeconomic burden. Environmental allergen exposure can be difficult to assess, and topical challenge offers limited value. In our investigation we evaluated a challenge chamber system in terms of correlation between mite allergen concentration and rhinitis symptoms, retest reproducibility as well as inter chamber variability. Data was obtained from adult mite allergic subjects from 4 different studies. Total nasal symptom score (TNSS) data was analysed for dose finding. TNSS and active anterior rhinomanometry (RMM) data was analyzed for retest reproducibility and inter chamber variability...

Human data about the potency of ethyl acrylate to evoke sensory irritation is currently not available. Therefore, we conducted an experimental exposure study and the magnitude of chemosensory effects in healthy human volunteers was mathematically modeled by combining the factors current concentration (c) and duration/time (t). In a repeated-measures design, 19 subjects were exposed for 4 h to constant and varying concentrations (including peaks of 5 and 10 ppm) of ethyl acrylate with either a 2.5 or 5 ppm time-weighted average (TWA) concentration...
