A new procedure, pyriform turbinoplasty, is described and nasal airflow is measured before and after this procedure in a virtual model.

Berberine (Ber), used widely as an antibacterial, antifungal, and anti-inflammatory drug, has long been used as a gastrointestinal remedy in Chinese traditional medicine. Recent reports have suggested that Ber suppresses Th17 responses that was mediated by direct actions on T cells and thymic stromal lymphopoietin production in primary mast cells. It has been suggested that Ber may be useful in treating allergic response. The purpose of this study was to assess the effects of Ber treatment on allergic inflammation in an allergic rhinitis mouse model and to examine the underlying mechanism(s).

Intranasal corticosteroids (INCS) are prescribed for the long-term prophylactic treatment of inflammatory upper airway conditions. Although some systemic absorption can occur via topical routes, the clinical relevance is controversial. The effects of orally administered corticosteroids on intraocular pressure (IOP) and lens opacity (LO) are well established, but the impact of the INCS is less well defined. This study aims to systematically review the literature for evidence of adverse occular events with INCS use.

The incidence of acute upper respiratory tract viral infections (URTI) is directly correlated to air temperature with most URTI occurring seasonally in cold weather. This review looks at four types of cold exposure and examines the evidence and possible mechanisms for any relationship to URTI. The effects of cold are discussed as: 1) Chilling of the nose and upper respiratory tract by breathing cold air, 2) Chilling of the mouth and upper digestive tract by ingestion of cold drinks and food, 3) Acute chilling of the body surface, and, 4) Chilling of the body as a whole with a fall in body temperature, hypothermia. Some studies were found to support a relationship between breathing cold air and chilling the body surface with the development of URTI, although this area is controversial. No evidence was found in the literature to support any relationship between ingestion of cold drinks and food and URTI, and similarly no evidence was found to link hypothermia and URTI.

Calcium plays an integral role in olfactory signal transduction, including feedback inhibition. Sodium citrate acts as a calcium sequestrant and when applied intranasally, reduces free calcium available for feedback inhibition, which should theoretically improve olfaction. We aimed to investigate the utility of intranasal sodium citrate in improving the olfactory function of hyposmic patients, by performing this prospective placebo controlled, single-blind trial.

Septoplasty is a frequently performed operation by otolaryngologists to relieve nasal obstruction complaints. When objective measurements tools are not available, preoperative decision-making is based on careful clinical examination. Our aim was to evaluate the relationship between type and severity of septal deviation and patient-reported nasal obstruction.

Common cold is the most common infectious disease of mankind and the term is widely used in the clinical literature as though it were a defined clinical syndrome. Clinical studies on this syndrome often use elaborate symptom scoring systems to diagnose a common cold. The symptom scores are based on a study conducted over 50 years ago to retrospectively diagnose experimental cold and this method cannot be applied to diagnosis of common cold in the community. Diagnosis of the common cold by virology is not feasible because of the number of viruses and the variability in the disease states caused by the viruses. Because of the familiarity of subjects with common cold and the variability in symptomatology it seems a more reasonable approach to use self-diagnosis of common cold for clinical research studies and accept that the common cold is a cultural concept and not a clinical entity.

The titanium butterfly implant seems to be a powerful technique to repair nasal valve insufficiency. However, the effect of these implants on nasal patency and quality of life has been controversial due to a lack of evidence. The purpose of this study is to evaluate the objective and subjective effect of the titanium butterfly implant on nasal patency and corresponding quality of life.

Eosinophilic chronic rhinosinusitis with nasal polyps (eCRSwNP) is characterized by Th2-skewed inflammation with eosinophilic infiltration. Thymic stromal lymphopoietin (TSLP) promotes the development of allergic inflammation. Although increased TSLP is found in eCRSwNP, little is known about whether TSLP regulates eotaxin-1 production, a potent eosinophil chemoattractant that recruits and activates eosinophils.

Chronic rhinosinusitis (CRS) is a common yet under-recognised chronic inflammatory disease of the nose and paranasal sinuses that is classified according to the presence (CRSwNP) or absence (CRSsNP) of nasal polyps.
