Abstract
Allergic rhinitis (AR) is a chronic, non-infectious condition affecting the nasal mucosa, primarily mediated mainly by IgE. Recent studies reveal that AR is intricately associated not only with type 2 immunity but also with neuroimmunity. Nociceptive neurons, a subset of primary sensory neurons, are pivotal in detecting external nociceptive stimuli and modulating immune responses. This review examines nociceptive neuron receptors and elucidates how neuropeptides released by these neurons impact the immune system. Additionally, we summarize the role of immune cells and inflammatory mediators on nociceptive neurons. A comprehensive understanding of the dynamic interplay between nociceptive neurons and the immune system augments our understanding of the neuroimmune mechanisms underlying AR, thereby opening novel avenues for AR treatment modalities.

Abstract
Nasal obstruction is the subjective perception and objective state of insufficient airflow through the nose. Nasal congestion, conversely, describes a state of not just inadequate airflow or obstructive phenomena but also pressure- and mucus-related states to the patient. Nasal receptors belonging to the transient receptor potential (TRP) protein family mediate the sense of nasal patency via the trigeminal nerve. The transient receptor potential melastatin-8 (TRPM8) responds to temperatures around 8°C to 22°C, and is stimulated by menthol and other cooling agents. The radiant effects of airflow create heat loss to activate these receptors and humans perceive this as nasal patency rather than the direct detection of airflow. The thermovascular state of the mucosa, in conditions such as rhinitis, influence TRPM8 activation. Nasal endoscopy can show signs of rhinitis and should be considered an essential part of the workup of nasal congestion. Efforts to relieve nasal congestion need to manage the mucosal state and surgery needs to ensures that the nasal cavity mucosa is exposed to the cooling effects of airflow rather than simply creating a passage to the nasopharynx.

Abstract
OBJECTIVES Chronic rhinosinusitis (CRS) with severe asthma are associated with breathing pattern disorder (BPD). Mouth breathing is a sign of breathing pattern disorder, and nose breathing a fundamental part of breathing pattern retraining for BPD. The prevalence of BPD in relation to CRS subtypes and the relationship of nasal obstruction to BPD in CRS and associated severe asthma is unknown. The breathing pattern assessment tool (BPAT) can identify BPD. Our objective was to thus investigate the prevalence of BPD, nasal airflow obstruction and measures of airway disease severity in CRS with (CRSwNP) and without nasal polyps (CRSsNP) in severe asthma. METHODS We determined whether CRS status, peak nasal inspiratory flow (PNIF) or polyp disease increased BPD prevalence. Demographic factors, measures of airway function and breathlessness in relation to BPD status and CRS subtypes were also evaluated. RESULTS 130 Patients were evaluated (n = 69 had BPD). The prevalence of BPD in CRS with severe asthma was 53.1%. There was no difference between BPD occurrence between CRSwNP and CRSsNP. The mean polyp grade and PNIF were not statistically different between the BPD and non-BPD group. The presence of nasal polyps did not increase breathlessness. CONCLUSIONS BPD and CRS are commonly co-associated. CRS status and nasal obstruction per se does not increase BPD prevalence.

Abstract
OBJECTIVE To investigate novel methods of measuring intranasal trigeminal function and correlate to validated measures of trigeminal function. STUDY DESIGN Prospective cohort study. SETTING Tertiary medical center. METHODS Forty-one subjects without nasal congestion were assessed. The trigeminal temperature function of the cool/warmth detection threshold and cold/heat pain threshold was measured with the Thermal Sensory Analyzer (TSA) device, as previously validated at buccal mucosa and infraorbital skin. Identical temperature sensory function was assessed at the anterior septum and inferior turbinate. Lateralization of trigeminal odorants eucalyptol, isothiocyanate, and acetic acid was conducted. Visual analog scales (VAS) of trigeminal function were collected. RESULTS Extraoral cheek site and oral site thermal measures were moderately correlated, suggesting consistent assessment of trigeminal function. Nearly all intranasal thermal measures correlated between the septum and turbinate (significant correlations [ρ] ranged from .3 to .8). Oral and extraoral cheek sites had modest correlations to intranasal cold and heat pain (ρ = .4-.5). The oral site had modest correlations of cold and heat detection to intranasal sites, with turbinate appearing to have the most correlations. Isothiocyanate lateralization was the most closely correlated to intranasal thermal scores for cold and heat pain. Turbinate thermal measures had weak correlations with trigeminal VAS scores (ρ = .3-.4). CONCLUSION Intranasal trigeminal measures of thermal function correlate to validated extraoral and intraoral thermal measures. The turbinate appears to have stronger correlations to the septum than found in the mouth and face. TSA testing might provide a rapid, novel method of intranasal trigeminal function assessment.

Abstract
This study aimed to assess efficacy of submucosal thulium laser turbinoplasty in children and to compare thulium laser turbinoplasty with partial inferior turbinectomy. This is a retrospective study over 10 years from 1 January 2009, conducted in a Pediatric Otorhinolaryngology Department in a university tertiary care center, including all the children who underwent thulium laser inferior turbinoplasty and partial inferior turbinectomy. The main outcome measures were the improvement in airflow using rhinomanometric cumulative flow at 150 Pa and then functional improvement using "OPERAS" score (nasal Obstruction, facial Pain, Epistaxis, Rhinorrhea, Anosmia, Sneezing). Eighty-six children underwent 47 submucosal thulium laser turbinoplasties and 48 partial turbinectomies. After submucosal thulium laser turbinoplasty, the cumulative flow at 150 Pa improved from 308.2 to 454.4 cm3 s-1 (p < 0.01) and the OPERAS score decrease was 1.5 point (p < 0.01). Daily use of intra nasal corticosteroid and antihistamine both decreased significantly. No local complications of this technique have been reported. Partial turbinectomies show a higher reduction of the OPERAS score and a better improvement of rhinomanometric parameters, but also a significantly higher complication rate. Submucosal thulium laser turbinoplasty is a good compromise between safety and efficacy, with substantial functional and rhinomanometric postoperative improvement.

Abstract
BACKGROUND Nasal obstruction is a common patient complaint and has a variety of etiologies, and a specific anatomical abnormality can often be found within the nasal cavity on physical examination. In practice, this observed pathology does not always correlate with the laterality, severity, and exact intranasal site of the patients' perceived obstruction. OBJECTIVES We seek to answer the following questions: 1) Does a physician's evaluation of nasal obstruction correlate with subjective patient complaints? 2) Is there reasonable correlation between physicians of similar training in the routine evaluation of nasal obstruction? METHODS First, we asked patients presenting to the otolaryngology clinic with a primary complaint of nasal obstruction to fill out a modified NOSE survey. Nasal endoscopy was performed on all subjects to assess all potential sites of obstruction. We then determined whether there is an association between patient complaints and findings on physical examination. Second, we determined if there is correlation between similarly trained physicians in their interpretation of a basic nasal examination. Otolaryngologists were shown a series of standardized videos of an endoscopic nasal examination that were recorded with a primary complaint of nasal obstruction. Findings were reported in an anonymous online survey focusing on laterality, severity, and specific site of perceived obstruction. RESULTS A total of 38 patients were included in the first part of the study. The Cohen's kappa coefficient was used to determine the interrater agreement between the patient and physician in the degree of nasal obstruction. The kappa coefficient was 0.03 (p value 0.372) for the comparison of the left-sided scores (fair agreement), and 0.16 (p value 0.014) for the right-sided scores (slight agreement). A comparison was also done between the side of the nose the patient felt was most obstructed to the most obstructed side found on physical exam by the otolaryngologist. Thirteen of the 38 patients (34%) had perceived nasal obstruction on the opposite side of that noted to be most obstructed on physical exam. Despite this, the kappa coefficient in this comparison was 0.43 (p value <0.001) revealing moderate agreement between the two groups. Seventeen otolaryngologists participated in the second part of the study. Data extrapolated revealed very little agreement among the physicians in reporting which side of the nose was most obstructed, what anatomical structure contributed to the obstruction the most, and what percentage obstruction was present. DISCUSSION Based on our findings, patients can reasonably determine based on their symptoms which side is most obstructed, but symptoms do not correlate with severity of obstruction when compared to physical exam. There is also very little consistency between otolaryngologists in their assessment of the degree of nasal obstruction on exam. The results of this study may have far-reaching implications for patient management, surgical intervention, and medicolegal documentation as it relates to the current surgical treatment of nasal obstruction.

Abstract
BACKGROUND The mechanism of nasal airflow sensation is poorly understood. This study aimed to examine the role of nasal mucosal temperature change in the subjective perception of nasal patency and the methods by which it can be quantified. METHOD Medline and PubMed database searches were performed to retrieve literature relevant to the topic. RESULTS The primary mechanism producing the sensation of nasal patency is thought to be the activation of transient receptor potential melastatin family member 8 ('TRPM8'), a thermoreceptor that is activated by nasal mucosal cooling. Computational fluid dynamics studies have demonstrated that increased airflow and heat flux are correlated with better patient-reported outcome measure scores. Similarly, physical measurements of the nasal cavity using temperature probes have shown a correlation between lower nasal mucosal temperatures and better patient-reported outcome measure scores. CONCLUSION Nasal mucosal temperature change may be correlated with the perception of improved nasal patency. Future research should quantify the impact of mucosal cooling on the perception of nasal airway obstruction.

Abstract
Medical devices provide people with some health benefits in terms of diagnosis, prevention, treatment, and monitoring of disease processes. Different medical specialties use varieties of medical devices more or less specific for them. Allergology is an interdisciplinary field of medical science and teaches that allergic reactions are of systemic nature but can express themselves at the level of different organs across the life cycle of an individual. Subsequently, medical devices used in allergology could be regarded as: 1) general, servicing the integral diagnostic and management principles and features of allergology, and 2) organ specific, which are shared by organ specific disciplines like pulmonology, otorhinolaryngology, dermatology, and others. The present position paper of the World Allergy Organization (WAO) is meant to be the first integral document providing structured information on medical devices in allergology used in daily routine but also needed for sophisticated diagnostic purposes and modern disease management. It is supposed to contribute to the transformation of the health care system into integrated care pathways for interrelated comorbidities.

Abstract
INTRODUCTION Among allergic rhinitis (AR) symptoms, nasal obstruction particularly affects the quality of life. Antihistamines and intranasal corticosteroids are the most frequently prescribed symptomatic drugs, but their efficacy is often incomplete. Essential oils (EO) have shown an anti-inflammatory effect and potential in treating patients with AR. The aim of this study was to evaluate the effectiveness of a hypertonic EO-based nasal spray on perennial AR (PAR) symptoms. METHODS This prospective, open-label, non-randomized, multicentric trial included 43 patients with PAR sensitized to mites, not controlled for more than a year. All were treated with Puressentiel® Respiratory-Decongestant Nasal Spray for 30 days. Their usual treatment remained unchanged during the study period. Before and after treatment, each participant filled out a rhinitis questionnaire, the Allergic Rhinitis Control Test (ARCT). A nasal inspiratory peak flow (NIPF) was performed. RESULTS The mean ARCT was 16.4 and 20.5 at D0 and D30, respectively (p < 0.001); the mean increase between D0 and D30 was 4.1 (p < 0.001). The proportion of patients with controlled rhinitis after 30 days of treatment was 69.8 versus 14% before treatment (p < 0.001). The mean NIPF was 86.5 L/min and 105.1 L/min at D0 and D30, respectively (p < 0.001); the mean increase between D0 and D30 was 18.5 L/min. CONCLUSION A hypertonic EO-based nasal spray could be a new and natural option in the management of PAR. It could also be used as an add-on therapy when nasal symptoms are not fully controlled.

Abstract
PURPOSE OF REVIEW To discuss the proposed pathophysiology of empty nose syndrome (ENS), summarize and evaluate the role of validated diagnostic tools in the diagnosis of ENS, and review the medical and surgical treatment strategies for patients with ENS. RECENT FINDINGS Historically, ENS has been associated with a reduction in nasal turbinate size; new data suggest that impaired trigeminal nerve function may also play a role in the pathophysiology of the disease. The newly validated empty nose syndrome 6 item questionnaires and Cotton test are steps forward to standardize the diagnosis of ENS. Finally, there has been a marked increase in surgical treatment strategies to reconstitute turbinate volume with various implant materials. SUMMARY The diagnosis of ENS remains controversial but the last several years have seen a rejuvenation of interest in this disease entity. The validated empty nose syndrome 6 item questionnaires and Cotton test provide a standardized and objective means by which to characterize ENS. Prevention of iatrogenic ENS through avoidance of excessive turbinate reduction remains critical in preventing paradoxical nasal obstruction. Nasal humidification, patient education, and treatment of possible concomitant medical conditions (e.g., depression) constitute first lines of treatment. We support the cautious use of these screening tools as adjuncts to clinical decision-making. Although injectable implants to augment turbinate volume show promise as a therapeutic surgical technique, there is insufficient data to fully support their use at this time.

Abstract
BackgroundThe last 5 years have seen a surge of both clinical and scientific interest in empty nose syndrome (ENS). Although ENS is still considered a controversial diagnosis plagued by a lack of standardized diagnostic criteria, ENS is increasingly becoming recognized as a legitimate, physiologic disease entity. As such, it is important for clinicians to understand the most up-to-date diagnostic tools to assess ENS, confirm the diagnosis, and create a more standardized means to counsel these complex patients.ObjectiveContemporary literature review to discuss diagnostic modalities in the evaluation of ENS, in order to introduce evidence-based diagnostic criteria.MethodsA systematic review was conducted in PubMed and Embase (2013–2019) using the search term “empty nose syndrome” to identify peer-reviewed articles on the topic of ENS. Articles advancing contemporary methods of ENS diagnosis and testing were included. A quality assessment was conducted using The Rational Clinical Examination Levels of Evidence.ResultsThe novel development of the Empty Nose Syndrome 6 Questionnaire (ENS6Q) offers the clinician a validated patient-reported outcome measure to supplement history and physical examination. The in-office cotton test, performed by placing an endoscopically directed cotton plug in the site of tissue loss, may help to identify patients who may benefit from turbinate augmentation. Tools such as the sinus computed tomography scan, computational fluid dynamics, and intranasal trigeminal nerve function testing currently have insufficient evidence to support routine use in the workup of ENS. Up to 66% of ENS patients present with comorbid anxiety or depression.ConclusionThe ENS6Q and cotton test assist in creating a standardized approach to the evaluation of patients suspected of ENS. These instruments should be used as an adjunct, rather than the sole criteria, on which to ascertain the presumptive diagnosis. Patients suspected of ENS should be screened for comorbid psychological dysfunction.

Abstract
The purpose of this case-control study is to report on the clinical application of nasometry as a diagnostic tool in patients with the symptom of nasal obstruction compared with subjects with no history of nasal obstruction. Thirty-eight adult patients (mean age: 28.1 years) complaining of nasal obstruction were enrolled in the study, and another group of 38 adults (mean age: 25.9 years) with no history of nasal obstruction served as controls. Demographic data, including age and sex, were collected. Patients were asked to read three passages; the Zoo passage, the Rainbow passage, and nasal sentences. Nasalance scores were reported on all subjects using a Nasometer II instrument. The control and patient groups each included 22 men and 16 women. No statistically significant difference in nasalance score was found between the study group and the control group in any of the Zoo passage, Rainbow passage and nasal sentences. We conclude that nasometry has limited value in the objective assessment of nasal obstruction as a symptom, which we attribute to nasal obstruction's not always reflecting the volume and pressure in the nasal cavity.

Abstract
During the 2017 IFOS international congress in Paris, a roundtable discussion on the topic of functional and aesthetic rhinoplasty was organised. Five experts, from the five continents and renown in the field of rhinoplasty, were brought together to discuss the issue from an international perspective and to put forward a consensus or on the contrary practical differences. Five questions were put to the experts beforehand to guarantee independent answers, which were then discussed during the roundtable. The questions were the following: - What are the age limits for achieving a rhinoplasty? - Do you use objective measurements before, during and after surgery? (facial landmarks, airflow, peroperative measurements) - How do you manage the preoperative general information and computer imaging of the patient? - What are the indications in your practice to perform a CT-scan or endoscopic examination before doing a rhinoplasty? - What kind of graft or prosthesis do you use for an augmentation rhinoplasty? This paper offers a synthesis of the roundtable based on the experts' answers to the different questions.

Abstract
Objectives To assess breathing behaviors and perception of added respiratory loads in young compared to old individuals, and to determine whether aging affects the perception and response to changes in nasal airway resistance. Study design In a clinical study, 40 young (11-20 years) and 40 older (59-82 years) subjects were evaluated during rest breathing and during the application of added airway resistance loads. Methods The pressure-flow technique was used to measure airflow rate (mL/s) and oral-nasal pressures (cmH2O) to calculate nasal resistance (cmH2O/L/s). To create calibrated resistance loads for the test conditions, we used a device modified from a precision iris diaphragm. Results During rest breathing airflow rate was significantly lower for the younger group compared to older group. Using the loading device, 11-20-year-olds detected increased resistance at the level of 2.26 cmH2O/L/s compared to 4.55 cmH2O/L/s in 59-82-year-olds. In contrast to the younger group, mean airflow rate was higher during expiration than during inspiration among 59-82-year-olds except at rest breathing. Conclusions The data revealed that the perception and respiratory response to increased airway resistance changed with aging. Younger subjects were more sensitive to changes within the airway. In both groups, subjects responded to increased airway resistance by decreasing airflow rate. However, expiratory phase became more active than inspiratory phase only in the older group.

Abstract
CONCLUSION Patient self-administration of the Kinetic Oscillatory Stimulation (KOS)-catheter was a fully acceptable alternative to insertion of the catheter by physician with helmet fixation, in patients with non-allergic rhinitis (NAR). The approaches were equivalent regarding pain. The treatment effect in the patient self-administration group was not inferior. OBJECTIVES To evaluate whether self-administration of a KOS-catheter was different compared to insertion by a physician, assessed with patient reported pain on a visual analogue scale (VAS). Also, to evaluate the difference in nasal stuffiness with the Sino-Nasal Outcome Test (SNOT-22) and Peak Nasal Inspiratory Flow (PNIF). METHODS Patients with NAR were randomized to group 1, patient insertion of catheter and manual fixation, and group 2, catheter insertion by physician and fixation with a helmet. Patients were treated once, 10 min in each nasal cavity, and followed up 14 days later. RESULTS Twenty-nine patients were included (group 1, n = 14; group 2, n = 15). There was no statistical significant difference in patient reported pain between groups. There was a decrease in nasal stuffiness after treatment in the total study population (n = 26, p = 0.001). In group 1 nasal stuffiness was decreased and in group 2 there was no change (group 1, p = 0.004; group 2, p = 0.071). No statistical significant change in PNIF was observed.

Abstract
Although variations in nasal index (NI) have been reported to represent adaptation to climatic conditions, assessments of NI with airflow variables have not been rigorously investigated. This study uses computational fluid dynamics modeling to investigate the relationship between NI and airflow variables in 16 subjects with normal nasal anatomy. Airflow simulations were conducted under constant inspiratory pressure. Nasal resistance (NR) against NI showed weak association from nostrils to anterior inferior turbinate (R(2)=0.26) and nostril to choanae (R(2)=0.12). NI accounted for 38% and 41% of the respective variation in wall shear stress (WSS) and heat flux (HF) at the nasal vestibule, and 52% and 49% of variability in WSS and HF across the entire nose. HF and WSS had strong correlation with NI<80, and weakly correlated with NI>80; these differences in HF and WSS for NI<80 and NI>80 were not statistically significant. Results suggest strong relationship between NI and both WSS and HF but not NR, particularly in subjects with NI<80.

Abstract
BACKGROUND Clinical evidence suggests that acupuncture improves symptoms in persistent allergic rhinitis, but the physiologic basis of these improvements is not well understood. OBJECTIVE A randomized, sham-controlled trial of acupuncture for persistent allergic rhinitis in adults investigated possible modulation of mucosal immune responses. METHODS A total of 151 individuals were randomized into real and sham acupuncture groups (who received twice-weekly treatments for 8 weeks) and a no acupuncture group. Various cytokines, neurotrophins, proinflammatory neuropeptides, and immunoglobulins were measured in saliva or plasma from baseline to 4-week follow-up. RESULTS Statistically significant reduction in allergen specific IgE for house dust mite was seen only in the real acupuncture group, from 18.87 kU/L (95% CI, 10.16-27.58 kU/L) to 17.82 kU/L (95% CI, 9.81-25.83 kU/L) (P = .04). A mean (SE) statistically significant down-regulation was also seen in proinflammatory neuropeptide substance P (SP) 18 to 24 hours after the first treatment from 408.74 (299.12) pg/mL to 90.77 (22.54) pg/mL (P = .04). No significant changes were seen in the other neuropeptides, neurotrophins, or cytokines tested. Nasal obstruction, nasal itch, sneezing, runny nose, eye itch, and unrefreshed sleep improved significantly in the real acupuncture group (postnasal drip and sinus pain did not) and continued to improve up to 4-week follow-up. CONCLUSION Acupuncture modulated mucosal immune response in the upper airway in adults with persistent allergic rhinitis. This modulation appears to be associated with down-regulation of allergen specific IgE for house dust mite, which this study is the first to report. Improvements in nasal itch, eye itch, and sneezing after acupuncture are suggestive of down-regulation of transient receptor potential vanilloid 1.

Abstract
Introduction Allergic rhinitis is considered the most prevalent respiratory disease in Brazil and worldwide, with great impact on quality of life, affecting social life, sleep, and also performance at school and at work. Objective To compare the efficacy and safety of two formulations containing mometasone furoate in the treatment of mild, moderate, or severe persistent allergic rhinitis after four weeks of treatment. Methods Phase III, randomized, non-inferiority, national, open study comparing mometasone furoate in two presentations (control drug and investigational drug). The primary endpoint was the percentage of patients with reduction of at least 0.55 in nasal index score (NIS) after four weeks of treatment. Secondary outcomes included total nasal index score score after four and 12 weeks of treatment; individual scores for symptoms of nasal obstruction, rhinorrhea, sneezing, and nasal pruritus; as well as score for pruritus, lacrimation, and ocular redness after four and 12 weeks of treatment. The study was registered at clinicaltrials.gov with the reference number NCT01372865. Results The efficacy primary analysis demonstrated non-inferiority of the investigational drug in relation to the control drug, since the upper limit of the confidence interval (CI) of 95% for the difference between the success rates after four weeks of treatment (12.6%) was below the non-inferiority margin provided during the determination of the sample size (13.7%). Adverse events were infrequent and with mild intensity in most cases. Conclusion The efficacy and safety of investigational drug in the treatment of persistent allergic rhinitis were similar to the reference product, demonstrating its non-inferiority.

Abstract
BACKGROUND Different nasal challenges induce neural and immune response leading to nasal and ocular symptoms in patients with seasonal allergic rhinitis (SAR). The release of neural mediators from nasal mucosa and conjunctiva after no-specific challenges in patients with SAR remains unknown. OBJECTIVES To compare the release of mediators from the nose and conjunctiva with symptoms after different nasal challenges in patients with SAR. METHODS Three types of consecutive nasal challenges were performed outside the pollen season in 25 patients with SAR. Challenges consisted of 500 biological units (BU) of allergen, 80 μg of histamine, and 1 mL of 2% hypertonic saline per nostril, within 24-hour and 72-hour intervals, respectively. Before and 15 minutes after challenges, evaluation of symptoms was performed with a visual analog scale. Concentrations of tryptase, eosinophil cationic protein in nasal lavages after 15 minutes, and substance P in tears after 5 minutes were measured with enzyme immunoassays. RESULTS Concentrations of substance P in tears were significantly higher after nonspecific challenges. Substance P concentration in tears significantly correlated with eye itchiness after histamine and hypertonic saline and with tearing after allergen. Ocular symptoms correlated significantly with tryptase concentration in nasal lavage collected 15 minutes after allergen challenge. There is a significant correlation in tear volume comparing different nasal challenges. CONCLUSIONS Nasal challenges with allergen, histamine, or irritants outside the pollen season induce a significant increase in nasal and ocular symptoms in patients with SAR. Interaction of the early-phase response and neurogenic inflammation define the pattern and severity of eye symptoms.

Abstract
Computational fluid dynamics (CFD) was used to simulate air flow changes in reconstructed nasal passages based on magnetic resonance imaging (MRI) data from a previous clinical study of 0.05% Oxymetazoline (Vicks Sinex Micromist®). Total-pressure boundary conditions were uniquely applied to accommodate low patency subjects. Net nasal resistance, the primary simulation outcome, was determined using a parallel-circuit analogy and compared across treatments. Relative risk (RR) calculations show that for a 50% reduction in nasal resistance, subjects treated with Sinex® are 9.1 times more likely to achieve this after 8 hr, and 3.2 times more likely after 12 hr compared to Sham.

Abstract
INTRODUCTION When there is a change in the physiological pattern of nasal breathing, mouth breathing may already be present. The diagnosis of mouth breathing is related to nasal patency. One way to access nasal patency is by acoustic rhinometry. OBJECTIVE To systematically review the effectiveness of acoustic rhinometry for the diagnosis of patients with mouth breathing. METHODS Electronic databases LILACS, MEDLINE via PubMed and Bireme, SciELO, Web of Science, Scopus, PsycInfo, CINAHL, and Science Direct, from August to December 2013, were consulted. 11,439 articles were found: 30 from LILACS, 54 from MEDLINE via Bireme, 5558 from MEDLINE via PubMed, 11 from SciELO, 2056 from Web of Science, 1734 from Scopus, 13 from PsycInfo, 1108 from CINAHL, and 875 from Science Direct. Of these, two articles were selected. RESULTS The heterogeneity in the use of equipment and materials for the assessment of respiratory mode in these studies reveals that there is not yet consensus in the assessment and diagnosis of patients with mouth breathing. CONCLUSION According to the articles, acoustic rhinometry has been used for almost twenty years, but controlled studies attesting to the efficacy of measuring the geometry of nasal cavities for complementary diagnosis of respiratory mode are warranted.

Abstract
Persistent rhinitis (PR) is a chronic disease that affects millions of people. However, it lacks of a useful method, which can indicate the actual severity of the inflammation in PR patients. This study was designed to seek an examination which could reflect the actual severity of PR disease. The serum Phadiatop test, ECP level, four-phase rhinomanometry, and acoustic rhinometry were assessed in 91 adult patients with PR and 10 healthy controls. The serum total IgE was determined in some of the patients and all of the controls. The patients were divided into four groups: ARWO, ARWTO, NARWO and NARWTO. 40% (22/55) of AR and 33.3% (13/36) of NAR patients never complained of persistent nasal obstruction. Serum ECP levels were increased in the ARWO group. Serum total IgE was significantly elevated in the AR groups. MCA(1-Min) and MCA(1-T) were significantly reduced in the ARWO, ARWTO, and NARWO groups. NV(6-Min) and NV(6-T) were decreased in all PR groups, but only some of these differences were significant. In the ARWO group, MCA(2-Min) (r = -0.252), MCA(2-T) (r = -0.377), NV(6-Min) (r = -0.32), and NV(6-T) (r = -0.311) had significant relationships with serum ECP. We recommend acoustic rhinometry as a useful routine tool for the diagnosis of PR, even among patients without persistent subjective nasal obstruction. This technique might reveal the actual status of nasal congestion. An elevated serum ECP level might indicate severe AR and is negatively correlated with the results of acoustic rhinometry.

Abstract
BACKGROUND Nasal obstruction is a common otolaryngologic complaint, yet the mechanism of sensing airflow is not commonly understood. The objective of this work was to review current knowledge on the physiological mechanism for sensing nasal airflow. METHODS Current literature pertaining to nasal sensation to airflow was retrieved using PubMed and Google Scholar searches. RESULTS The primary physiological mechanism that produces the sensation of ample nasal airflow is activation of trigeminal cool thermoreceptors, specifically transient receptor potential melastatin family member 8 (TRPM8), by nasal mucosal cooling. The dynamic change in temperature is ultimately sensed. Nasal mucosal cooling is a result of conductive heat loss, driven by temperature gradient, and evaporative heat loss, driven by humidity gradient. The perception of ample nasal airflow is dependent on the overall nasal surface area stimulated by mucosal cooling, which is mainly governed by air flow patterns. Cool thermoreceptors in the nasal mucosa are connected to the respiratory centers and consequently can alter respiration patterns. Mechanoreceptors do not seem to play a role in sensing nasal airflow. Computational fluid dynamics (CFD) modeling could be a valuable objective tool in evaluating patients with nasal congestion. CONCLUSION Understanding the physiological mechanism of how the nose senses airflow can aid in diagnosing the cause behind patient symptoms, which allows physicians to provide better treatment options for patients.

Abstract
CONCLUSION Kinetic oscillation stimulation (KOS) of nasal mucosa at low frequency seems to be a possibly effective and safe short-term treatment of non-allergic nasal stuffiness. OBJECTIVE To assess the relief of rhinitis symptoms, especially stuffiness, by comparing active treatment, i.e. KOS at low frequency of the nasal mucosa, with placebo. METHODS Patients were randomized to active or placebo treatment in this double-blinded parallel design study. Treatment with an inflatable oscillating catheter was administered on day 0, and symptom scores (stuffiness, secretion, and itching) were graded daily until day 14. An overall grading of symptoms from 1 week before treatment and during 14 days thereafter was made at day 14. Eighty-six patients (52 with non-allergic perennial rhinitis, NAR; 34 with rhinitis medicamentosa, RM) were randomized, and 71 were evaluated (active treatment, n = 35; placebo, n = 36). RESULTS Patients with either NAR or RM who received active treatment reported reduced symptom scores by some measures, e.g. median RQSS stuffiness measure fell from 2 to 1 on a scale from 0 to 3 during the week following treatment. No significant effect was observed for patients treated with placebo. Mild side effects were reported.

Abstract
OBJECTIVE Nasal congestion is a common symptom in allergic and nonallergic rhinitis, rhinosinusitis and nasal polyposis. The present study evaluated the clinical effectiveness of Narivent(®), an osmotically-acting medical device with anti oedematous and anti-inflammatory effects, in nasal congestion. METHODS A single-centre, prospective study with a pre- post design and consecutive patient enrolment was conducted in an Italian otolaryngology department. Patients with persistent nasal congestion were allocated to treatment groups as follows: group 1 (n = 36) treated for 7 days; group 2 (n = 56) treated for 30 days. In each group, patients received two puffs of Narivent(®) into each nostril twice daily. Symptom severity was assessed subjectively on a 0-10 visual analogue scale, and objectively by the presence/absence of signs and symptoms. Differences in subjective and objective severity measures before and after treatment were compared using Wilcoxon's signed rank test. RESULTS All symptoms and objective scores improved after treatment with Narivent(®) for 7 or 30 days and no adverse effects were reported by the patients in either group. CONCLUSION Narivent(®) appears to be efficacious in treating nasal congestion over a 7- or a 30-day period.

Computational fluid dynamics: a suitable assessment tool for demonstrating the antiobstructive effect of drugs in the therapy of allergic rhinitis. ACTA OTORHINOLARYNGOLOGICA ITALICA : ORGANO UFFICIALE DELLA SOCIETA ITALIANA DI OTORINOLARINGOLOGIA E CHIRURGIA CERVICO-FACCIALE 2013; 33:36-42.

Abstract
This systematic review aims first to summarize the previous areas of application of computational fluid dynamics (CFD) and then to demonstrate that CFD is also a suitable instrument for generating three-dimensional images that depict drug effects on nasal mucosa. Special emphasis is placed on the three-dimensional visualization of the antiobstructive effect of nasal steroids and antihistamines in the treatment of allergic rhinitis. In the beginning, CFD technology was only used to demonstrate physiological and pathophysiological airflow conditions in the nose and to aid in preoperative planning and postoperative monitoring of surgical outcome in the field of rhinosurgery. The first studies using CFD examined nasal respiratory physiology, important functions of the nose, such as conditioning and warming of inspired air, and the influence of pathophysiological changes on nasal breathing. Also, postoperative outcome of surgical procedures could be "predicted" using the nasal airflow model. Later studies focused on the three-dimensional visualization of the effect of nasal sprays in healthy subjects and postoperative patients. A completely new approach, however, was the use of CFD in the area of allergic rhinitis and the treatment of its cardinal symptom of nasal obstruction. In two clinical trials, a suitable patient with a positive history of allergic rhinitis was enrolled during a symptom-free period after the pollen season. The patient developed typical allergic rhinitis symptoms after provocation with birch pollen. The 3-D visualization showed that the antiallergic treatment successfully counteracted the effects of nasal allergen provocation on nasal airflow. These observations were attributed to the antiobstructive effect of a nasal steroid (mometasone furoate) and a systemic antihistamine (levocetirizine), respectively. CFD therefore constitutes a non-invasive, precise, reliable and objective examination procedure for generating three-dimensional images that depict the effects of drugs used in the treatment of allergic rhinitis.
