Ophthalmic adverse effects of nasal decongestants on an experimental rat model.

To investigate the potential effects of chronic exposure to a nasal decongestant and its excipients on ocular tissues using an experimental rat model.


Effects of decongestant addition to intranasal corticosteroid for chronic rhinitis: a systematic review and meta-analysis.

Intranasal corticosteroid (INCS) is the most efficacious medicine for treating chronic rhinitis. A decongestant and INCS combination (INCS-D) is considered for nasal congestion that is not improved by INCS. This study aimed to investigate the effects of INCS-D on chronic rhinitis.

Pediatric Nasal Traumas: Contribution of Epidemiological Features to Detect the Distinction Between Nasal Fractures and Nasal Soft Tissue Injuries.

Nasal bone is prone to injury due of its prominent position on the face. Epidemiologic surveys are necessary to investigate nasal traumas. The aim of the present study is to examine the distribution of trauma etiologies according to age, sex, and seasonality in pediatric patients who present with nasal trauma, and to classify the pathologies according to their etiology as nasal fractures or nasal soft tissue injuries.


Pediatric Nasal Obstruction.

Nasal obstruction is one of the most common problems seen by pediatric otolaryngologists. Prompt treatment of nasal obstruction can be critical in newborns and infants because of their obligatory nasal breathing. Older children will typically have more inflammatory, infectious, or traumatic causes of nasal obstruction. Nasal obstruction can lead to a significant decrease in the quality of life in children along with an increase health care expenditures.

Nasal ventilation is an important factor in evaluating the diagnostic value of nasal nitric oxide in allergic rhinitis.

The role of nasal nitric oxide (NO) in the diagnosis of allergic rhinitis (AR) is controversial. The aim of this study was to identify factors that may affect levels of nasal NO in AR patients and evaluate the role of nasal NO in the diagnosis of AR.

Integration of the nasal complex: Implications for developmental and evolutionary change in modern humans.

Assessing the strength of integration among different regions of the modern human nasal complex is important for developing a more thorough understanding of the determinants of nasal morphology. Given the morphogenetic influence of cartilage on adjacent intramembranous growth sites, the interaction between chondrocranial- versus intramembranous-derived nasal structures may have a significant influence on patterns of nasal variation. The purpose of this study is to examine integration between the chondrocran...

Safety and Efficacy of Cosmetic Augmentation of the Nasal Tip and Nasal Dorsum With Expanded Polytetrafluoroethylene: A Randomized Clinical Trial.

Expanded polytetrafluoroethylene (ePTFE) is a widely used alloplast, but studies of augmentation of the nasal tip and nasal dorsum with ePTFE are lacking.

Numerical simulation of two consecutive nasal respiratory cycles: toward a better understanding of nasal physiology.

Computational fluid dynamic (CFD) simulations have greatly improved the understanding of nasal physiology. We postulate that simulating the entire and repeated respiratory nasal cycles, within the whole sinonasal cavities, is mandatory to gather more accurate observations and better understand airflow patterns.

Allergic conversion of protective mucosal immunity against nasal bacteria in chronic rhinosinusitis with nasal polyposis.

Chronic rhinosinusitis with nasal polyposis (CRSwNP) is characterized by eosinophilic inflammation and polyposis at the nose and paranasal sinus and a high concentration of IgE in nasal polyps (NPs). The causative antigen and pathogenesis of CRSwNP remain unknown.

The Nasal Ligaments and Tip Support in Rhinoplasty: An Anatomical Study.

In 1971, Janeke and Wright1 published a now classic study on the support of the nasal tip in which they found four areas of anatomic support. These findings led to the "tripod concept" of tip support. Recently, surgeons have begun repairing and/or preserving the nasal ligaments as a method to control tip projection and rotation. Therefore, a reassessment of the nasal ligaments and tip support is warranted.

NAVIGATE II: randomized, double-blind trial of the exhalation delivery system with fluticasone (EDS-FLU) for nasal polyposis.

Chronic rhinosinusitis (CRS) is common and sometimes complicated by nasal polyps (NP). Corticosteroid nasal sprays are often unsatisfactory because they are ineffective at delivering medication to high/deep sites of inflammation.

Schwannoma of the Membranous Nasal Septum: a Clinical Report With Aesthetic Approach.

Schwannoma is an uncommon tumor of nerve sheath that arises from any peripheral, cranial, or autonomic nerve. Only 4% of head and neck schwannomas originate from the sinonasal tract, and a finding of a schwannoma in the nasal septum is exceedingly rare. The authors experienced nasal septal schwannoma with the functional and aesthetic consideration of nasal contour. The authors present an open rhinoplasty approach for nasal septal schwannoma which has not been reported in the previous literature yet.

Improving Postoperative Nasal Airway Patency in Le Fort-Based, Maxillofacial Trauma Patients Via a Modified Nasal Packing Technique.

Combined mid-face and nasal apparatus trauma injuries pose a significant challenge to airway patency (AW), in the immediate postoperative setting following fracture reduction. As such, the authors describe a modified technique with the goal of maintaining a patent nasal AW, while at the same time, minimizing nasopharyngeal bleeding and nasal AW edema-which can complicate patients requiring intermaxillary fixation (IMF) in the setting of pan-facial trauma.

Effect of early correction of nasal septal deformity in unilateral cleft lip and palate on inferior turbinate hypertrophy and nasal patency.

A relatively neglected aspect of cleft lip nasal deformity is the effect of septal deviation and inferior turbinate hypertrophy (ITH) on the functional airway. In particular, ITH in the noncleft side can be especially problematic, because it reduces the healthy nasal area, creating bilateral nasal obstruction that might affect the growth of the maxillofacial skeleton. Although these anatomic and functional changes are documented, few recommendations have been developed regarding the proper approach to ITH. ...

Influence of the location of nasal polyps on olfactory airflow and olfaction.

Chronic rhinosinusitis with nasal polyps (CRSwNP) often results in decreased olfaction. In this study, we examined the relationship between nasal polyp location and olfactory airflow and odorant transport changes using virtual nasal polyp models at different locations and computational fluid dynamics (CFD) analysis. We also compared olfactory airflow and olfaction between patients with nasal polyps at different locations using CFD analysis and an olfactory test.

Expanded Paramedian Forehead Flaps for Nasal Defects: Beyond Aesthetic Subunits.

Reconstruction of nasal tip defects presents a significant challenge for plastic surgeons. The form, function, and aesthetic appeal of all nasal subunits must be addressed. The expanded paramedian forehead flap is a good choice for nasal reconstruction, providing similar texture, structure, and skin color, and high reliability. This article discusses the authors' modification of the expanded paramedian forehead flap in reconstructing defects on or around the nasal tip.

A Simplified Geometric Model to Predict Nasal Spray Deposition in Children and Adults.

A mathematical approach was developed to estimate spray deposition patterns in the nasal cavity based on the geometric relationships between the emitted spray plume and the anatomical dimensions of the nasal valve region of the nasal cavity. Spray plumes were assumed to be spherical cones and the nasal valve region was approximated as an ellipse. The effect of spray plume angle (15-85°) on the fraction of the spray able to pass through the nasal valve (deposition fraction) was tested for a variety of nasal...

Staphylococcus aureus enhances the tight junction barrier integrity in healthy nasal tissue, but not in nasal polyps.

Staphylococcus aureus infection increases the expression of the tight junctions (TJs) in healthy nasal tissue; while nasal polyps show decreased TJ expression at baseline and are unable to upregulate TJs to strengthen the epithelial barrier.

Assessment of Pliability and Elasticity of the External Nasal Skin in Patients With Unilateral Nasal Valve Collapse: A Static Biomechanical Evaluation.

Understanding the skin biomechanics, specifically pliability and elasticity, in patients with nasal valve collapse may allow for new methods to assess which patients require more advanced nasal valve surgery.

The lack of nasal tip support resulting in poor protection and projection of the nose is a common cause of nasal obstruction and cosmetic impairment. Although septal cartilage is preferred for restoration of nasal tip support, there is often not enough septal cartilage available. We describe an intercrural columellar strut graft in a circumferential soft tissue pocket: the I-Beam technique.

Nasal Structural and Aerodynamic Features that may Benefit Normal Olfactory Sensitivity.

Nasal airflow that effectively transports ambient odors to the olfactory receptors is important for human olfaction. Yet, the impact of nasal anatomical variations on airflow pattern and olfactory function are not fully understood. In this study, 22 healthy volunteers were recruited and underwent CT scans for computational simulations of nasal airflow patterns. Unilateral odor detection thresholds (ODT) to l-Carvone, phenylethyl alcohol (PEA) and d-Limonene were also obtained for all participants. Significa...

Study on the relationship between nasal and eye symptoms and psychological status in patients with allergic rhinitis.

The aim of this study is to analysis the correlation between nasal and eye symptom and psychological status in patients with allergic rhinitis, in order to provide a basis for improving the mental health of patients. The nasal symptom score scale, eye symptom score scale and Kessler 10 were used in the study, and the survey data was analyzed. At least one of 147 patients had a nasal symptom at a rate of 100% (147/147); at least one ocular symptom was 86.4% (127/147). Of the 147 patients, 29 had K10 scores m...

Expression profiles of CD11b, galectin-1, beclin-1, and caspase-3 in nasal polyposis

Background/aim: Nasal polyposis is a chronic inflammatory disease affecting the paranasal sinuses and nasal mucosae. It is thought that genetic and molecular mechanisms in inflammatory and apoptotic pathways are the main factors in the etiopathogenesis of nasal polyposis. The aim of this study was to investigate the expression patterns of CD11b, galectin-1, beclin-1, and caspase-3 in nasal polyps.Materials and methods: The mRNA expression levels of CD11b, galectin-1, beclin-1, and caspase-3 protein and west...

Nasal-type extranodal T-cell/NK lymphoma in association with hemophagocytic syndrome.

Extranodal NK/T-cell lymphoma nasal type is a rare disease that mainly affects the nasal cavity and paranasal sinuses of males in the fifth decade of life. It has aggressive and locally destructive behaviour, and can be complicated by the hemophagocytic syndrome, conferring high lethality to the disease. This article describes a case of NK/T-cell lymphoma nasal type in a previously healthy patient, exemplifying its rapid and fulminant course.
