Pilot study of bioabsorbable implant and delivery device for correction of septal deviation.
Nasal patency is an important component of performing exercises because it helps in humidifying, heating and filtering the inhaled air. However, many athletes and exercisers experience difficulty breathing through their nose, which can affect their breathing and performance. Namely, during sports activities and greater physical effort, there is increased air flow, which causes significant dehydration and cooling of the mucous membrane of the upper respiratory system. This dehydration is associated with the release of inflammatory mediators, which can ultimately lead to narrowing of the airways (eg in athletes with asthma). However, in all athletes, regardless of whether they have asthma or not, damage to the airways can occur because during exercise, hyperpnea exposes the respiratory epithelium to increased physical forces and pressure, which leads to the risk of exfoliation of the previously dehydrated epithelial cells of the nose and even their complete separation. Repeated stretching and compression can negatively affect the functionality of the epithelium and, with repeated exposure and damage, lead to structural and functional changes. Rinsing the nose with a hypertonic or isotonic solution of seawater is a potential solution for nasal obstruction because after rinsing, the airflow through the nose improves and symptoms of obstruction are reduced. However, the effects of using nasal lavage solutions along with exercise in elite athletes are not yet known. The potential synergy of exercise and isotonic seawater solution as a nasal spray on airflow and the subjective impression of nasal patency in healthy individuals has not been sufficiently investigated5. Research question What is the effect of an isotonic seawater solution applied as a nasal spray on nasal airflow and the subjective impression of nasal obstruction in healthy athletes? Hypothesis An isotonic seawater solution applied as a nasal spray will improve nasal airflow and the subjective impression of nasal obstruction in healthy athletes.
The aim of the project is to determine whether nasal inspiratory peak flow is sufficient for preoperative and postoperative measurement of nasal patency compared to rhinomanometry.
About 13% of US adults, some 30 million people, suffer from nasal sinus disease. Although nasal obstruction and smell loss are two of the major symptoms of the disease that are crucial to disease management, currently there is a lack of clinical tools to effectively evaluate the mechanisms contributing to these symptoms. The proposed study aims to develop novel clinical tools to better evaluate and relieve patients' nasal obstructive symptoms and to enable patients and clinicians to make more informed, personalized decisions regarding treatment strategy.
The Novapak study is a prospective, observational, multi-site, non-controlled, non-randomized, case-series, with a 2 week and 1-month follow-up in adults undergoing nasal/sinus surgery with Novapak Nasal Sinus Packing and Stent device used as indicated post-operatively and is being conducted to obtain clinical data on the safety and effectiveness of the Novapak device under use as intended in the device indications.
Septoplasty is one of the most common procedures in rhinology. In many centers and private institutions, an infundibulotomy is performed in addition to septoplasty without evidence of significant improvement for the patient. Often the reason given for this is the improvement of the functional outcome in terms of better nasal breathing, although there is no evidence for this. If a significantly better outcome can be shown, one would have a first evidence for the extended procedure.
The aim of the study is to evaluate the effect of nasal desobstruction surgery (septoplasty, septorhinoplasty or total ethmoidectomy) on sleep quality, assessed by the variation of the Wake after sleep onset (WASO), in patients presenting with sleep disorders and severe nasal obstruction.
This is a prospective, single-center study. This study seeks to determine the objective improvement in nasal airflow in patients after undergoing the VivAer procedure, which involves the use of a stylus to deliver controlled and targeted low energy radiofrequency heating (heating by applying high-frequency radio waves) to the nasal sidewall to gently reshape the tissues. Patients who experience refractory, or medically unexplained, nasal obstruction often have symptoms that are not alleviated or resolved by standard non-surgical treatment options. VivAer, a recently developed, FDA-approved procedure, is one of the standard surgical treatments for nasal obstruction. Unlike most of the other established surgical treatments for nasal obstruction, however, VivAer is a minimally-invasive procedure, and it is an outpatient intervention that can be performed under local anesthetic. Eligible patients who are enrolled in the study will undergo the VivAer procedure, and will return to the clinic for three in-office follow-up visits at 4, 12, and 24 weeks after the procedure.
The researchers are investigating if the Self-Supporting Nasopharyngeal Airway (ssNPA) device can be used in the treatment of obstructive sleep apnea in children with Hypotonic Upper Airway Obstruction (HUAO).
