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.
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.
The nasal tip is the most prominent part of the nose. The aim of this paper is to review nasal tip grafts with detailed explanation and figures.
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.
Creation of a pleasing dorsal nasal profile in the anterior and lateral views requires proper analysis and planning to determine the required series of steps to accomplish the desired outcome. The widened nasal dorsum is a common esthetic complaint of the patient seeking rhinoplasty. Often patients seek an unrealistic result that, if accomplished, would leave them with a restricted nasal vault and nasal airway compromise. Nasal function must be balanced with the patient and surgeon's desire to narrow the na...
Many studies have indicated associations between impaired nasal breathing and sleep disorders. However, the precise nature of the relationship between nasal patency and sleep remains unclear.
Postoperative packing in nasal surgery often results in nasal obstruction and discomfort. Commercially available silicone intranasal airways (IAs) serve as dual-nasal airway tubes aimed at alleviating this process, but the safety and efficacy of these devices are unknown.
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.
Nasal obstruction is one of the most frequent and bothersome symptoms in rhinosinal disease. Although we are able to measure nasal airflow, the correlation between the feeling of nasal obstruction and objective measurements has been shown to be average at most. A significant proportion of the European population has a more or less deviated nasal septum and deviated septa have received a lot of attention from otorhinolaryngologists. In sharp contrast is the amount of hard evidence concerning septoplasty with...
Nasal and blowout fractures are the most common injuries from craniomaxillofacial trauma. Nasal fractures are easily diagnosed by clinical signs, such as pain and crepitus. However, blowout fractures are frequently asymptomatic and are easy to miss without computed tomographic (CT) scanning. This study analyzed the relation between the 2 fracture types to determine whether nasal fracture could be used as a predictor of blowout fracture.
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...
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.
Nasal obstruction is a highly subjective and commonly reported symptom. The internal nasal valve (INV) is the rate limiting step to nasal airflow. A static INV grading score was devised with regard to visibility of the middle turbinate.
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...
Nasal drug delivery has attracted significant attention as an alternative route to deliver drugs having poor bioavailability. Large-molecule drugs such as peptides, and central nervous system drugs, would benefit from intranasal delivery. Drug absorption after intranasal application depends on the nasal retention of the drug, which is determined by the nasal mucociliary clearance. Mucociliary clearance (MC) is an important determinant of the rate and extent of nasal drug absorption. The aim of the present s...
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.
Wegener granulomatosis (WG) is a necrotizing vasculitis that involves the upper respiratory tract, the lungs, and the kidneys. It also causes deformities of the nose in practically all patients, altering the cartilaginous and bony structure as well as the inner lining of the nose.The surgical repair of these nasal distortions is a challenge mainly due to the impairment of wound healing and graft take that is caused both by the disease itself and by the prolonged immunosuppressant treatment.Many different re...
This study aims to explore the roles, and related mechanisms of miR-375 in nasal mucosa cells apoptosis and allergic rhinitis. Here, miR-375 was found to be decreased in the epithelia of nasal mucosa of allergic rhinitis mice and TNF-α-stimulated nasal mucosa cells, while JAK2 expression exhibited an opposite effect. Mechanistically, miR-375/JAK2 regulatory axis was identified in nasal mucosa cells via luciferase reporter, qRT-PCR, western blot and RNA immune co-precipitation (RIP) assays. Pre- or post-inj...
A novel PCR assay detected IgE M1 prime transcripts in nasal polyps of patients with CRSwNP and asthma, confirming that IgE switching occurred and membrane IgE-expressing B cells were resident at mucosal sites.
Effects of mometasone furoate-impregnated biodegradable nasal dressing on endoscopic appearance in healing process following endoscopic sinus surgery: a randomized, double-blind, placebo-controlled study.
Postoperative care is an important factor affecting the outcome of endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS). The aim of this study was to test the effect of mometasone furoate (MF)-soaked biodegradable nasal dressings (BNDs) on endoscopic appearance in CRS patients with nasal polyps (CRSwNP) after ESS.
A male Mongolian child with a complete congenital absence of both nose and nasal passage had a poor survival prognosis due to respiratory distress. To enable his survival, a new nose capable of conferring respiratory function was constructed. Following reconstructive surgery, an absence of mucoepithelium in the nasal passage can lead to rhinostenosis. To avoid this complication, a custom-made nasal silicone stent was created using three-dimensional (3D) printing technology in conjunction with the patient's ...
Nurses frequently administer nasal oxygen therapy for patients in intensive care units (ICUs). However, little is known about the current status, nurses' management and perception on the nasal oxygen therapy in China. Therefore, we aimed to investigate the nasal oxygen practice of ICUs in China to provide insights into future direction.
Rhinitis and rhinosinusitis are olfactory disorders caused by inflammation of the nasal passage and paranasal sinuses. Although chronic rhinosinusitis patients have smaller olfactory bulbs (OBs), there is limited knowledge regarding the influence of chronic nasal inflammation on OB neurons.
5-Oxo-6,8,11,14-eicosatetraenoic acid (5-oxo-ETE) is a potent eosinophil chemoattractant and activator that is synthesized not only in inflammatory cells but also in bronchial epithelial cells. The purpose of this study is to clarify whether 5-oxo-ETE can promote the production of eosinophil cation protein (ECP) by eosinophils in nasal polyps (NP) in vitro, and whether normal nasal epithelial cells can produce this lipid mediator in response to oxidative stress.
