The 5-dimensional EuroQol questionnaire (EQ-5D) is validated to measure general health-related quality of life (QOL). Our objective was to determine the responsiveness and minimal clinically important difference (MCID) of the EQ-5D health utility value (EQ-5D HUV) and visual analog scale (EQ-5D VAS) in chronic rhinosinusitis (CRS).

The June 2018 issue of Rhinology paves the way for real-life implementation of Precision Medicine in Rhinology, with Predictive Medicine in the center of attention. Physicians treating patients with rhinologic disorders might find it extremely interesting to find reports on predictors of success of medical or surgical interventions. Prediction of success of treatment is crucial to allow the patient become an active partner in the decision-making process of medical or surgical treatment. Defining the clinical phenotype of patients with chronic rhinosinusitis responding well to either revision surgery or long-term oral macrolide treatment represents a true challenge.

Chronic rhinosinusitis (CRS) can be divided to CRS without nasal polyps (CRSsNP) and eosinophilic and non-eosinophilic CRS with nasal polyps (CRSwNP). There is little evidence on the efficacy of glucocorticoids and macrolides in different phenotypic patients. The aim of this study was to compare the benefit of glucocorticoids and macrolides following endoscopic sinus surgery (ESS) in different phenotypic CRS.

The treatment strategy of squamous cell carcinoma of the nasal vestibule (SCCNV) is controversial. The objective of this study is to investigate the role of surgery, which is the preferred treatment option at our institution.

The aim of the present study was to provide an insight into medical treatment practices among patients with chronic rhinosinusitis (CRS) in Germany. An investigation of ICD codes and ATC classes of CRS patients in general and otolaryngology offices in Germany should reveal the prevalent treatment behaviors of German physicians.

Olfactory training (OT) has been shown to increase olfactory performance in healthy subjects and patients with post-traumatic or post-infectious olfactory loss. Morphological correlates such as olfactory bulb volume increase and gray matter changes suggest central changes in olfactory brain areas following olfactory exposure. Some evidence from animal studies indicates peripheral changes upon OT whereas no such data exist in humans. This study explores the question whether changes in olfaction following OT are associated with alterations of the electro-olfactogram (EOG) derived from the olfactory epithelium.

Olfactory dysfunction significantly impairs the life quality of patients. Therefore, a model needs to be developed for anosmia. Chitosan is a biodegradable natural polysaccharide that has been widely studied for regenerative purposes in the nervous system. However, whether chitosan promotes differentiation of olfactory receptor neurons or regulates formation of neurospheres in the olfactory system remains unexplored.

Nose reconstruction following resection of nasal carcinomas is controversial. The objective of this study is to investigate the effect of surgical reconstruction versus prosthetic rehabilitation on patient quality of life (QOL).

Prevention of chronicity of disease and minimising its impact with individualized treatment is a fundamental tenet of precision medicine. A review of the literature has been undertaken to explore how this may apply to chronic rhinosinusitis (CRS). Prevention may be thought of across 3 main domains. Primary prevention of CRS focuses on the avoidance of exposure to environmental factors associated with increased incidence of disease. This includes avoidance of tobacco smoke and occupational toxins. Although allergic rhinitis, respiratory infections and gastro-oesophageal reflux have been shown to be risk factors, there is no evidence as yet that treatment of these conditions is associated with reduced incidence of CRS. Secondary prevention of CRS is concerned with detecting a disease in its earliest stages, intervening to achieve disease and symptom control and preventing future exacerbations. Evidence based guidelines facilitate early diagnosis and appropriate use of medical and surgical interventions. In the future the use of endotypes to direct optimal is like to allow more clinically and cost-effective use of current and emerging treatments, such as monoclonal antibodies. Tertiary prevention aims to minimise the impact of an ongoing illness or injury that has lasting effects. Anxiety and depression have been shown to be associated with symptom amplification and may require treatment. The role of disease-related factors such as the role of the microbiome and osteo-neogenesis in the development of chronicity, and the development of severe combined upper airway disease needs further research.

The nose is a dynamic organ and is the first point of contact between inhaled air and mucosal surfaces. Within the nasal cavity, there are changes of air flow and pressure occurring during the respiratory cycle, as well as exchanges of heat and humidity, and important immune responses to inhaled antigens and allergens.
