Filter by:A Prospective, Multicenter, Non-Randomized Study of the Aerin Medical Vivaer ARC Stylus for Nasal Airway Obstruction
We know that there is a link between disorders in the upper and lower airways, both epidemiologically, patho-physiologically, and therapeutically. What we know less about is the role for the nose and nasal breathing for physical capacity. That goes both for the ability of the average, healthy persons well as for patients with ie. asthma and COPD to perform daily life activities as well as exercise and for top athletes to perform their maximum oxygen demanding activities. Without this knowledge, we cannot make evidence based decisions about to what extent measures to open the nose medically and/or surgically should be considered to improve physical capacity at any level. The aim of the present project is to expand our knowledge in the field for the best of the ordinary man, patients with airway disorders, and athletes.
The purpose of this study is to compare the Vivaer procedure with radiofrequency (RF) energy to sham procedure for treatment of nasal airway obstruction (NAO).
Nasal obstruction is one of the majors concerns in reduction rhinoseptoplasty, because it affects quality of life and surgical outcomes. Is the association of middle third grafts with reduction rhinoseptoplasty responsible for an increase in quality of life related to nasal obstruction when compared to reduction rhinoseptoplasty without the placement of these grafts?
The purpose of this observation study is to evaluate long term safety and efficacy at 2~3 years after surgery on patients who have completed nasal septal deformity surgery using TnR Nasal Mesh.
Post-market study to continue to evaluate the effectiveness of the Vivaer® ARC Stylus for nasal airway obstruction
This study aims to demonstrate a decrease with normalization of nasal resistance in the forward decubital position and with an intra-nasal stent in patients with nasal obstruction.
Pathological-anatomical changes in the nasal cavity (nasal septum/perforation, mucosal hypertrophy) negatively affect nasal airflow, increase resistance - cause nasal obstruction and are often an indication for surgery. The aim of the study is to examine nasal airflow parameters after septoplasty and turbinoplasty .
This study compares the efficacy of a single intra-operative (intravenous) dose of "cephalexin" (first generation cephalosporin) or "clindamycin" (lincosamides), alone versus both intra-operative (intravenous) dose of "cephalexin" (first generation cephalosporin) or "clindamycin" (lincosamides) and postoperative oral dose of "cephalexin" or "clindamycin" use in nasal surgery.
Breathing is a crucial function for everyone. Breathing impairment in children could lead to behavioral and cognitive problems at least. But what if orthodontic treatment could help those patients to breathe better, with less effort? This research proposal aims to find out if the increase in the upper airway volume seen in some research results can be related to a decrease in respiratory effort and an improvement in the breathing capacity of those patients. In other words, if a tube shape is changed or if a tube is enlarged, would the airflow passing inside the tube change in velocity? Or would there be more air? Therefore, investigating the pressure/airflow, volume/lumen relation and its possible changes after mandibular repositioning and maxillary expansion in children will lead to a better understanding of how orthodontics could potentially affect the upper airway. Previous studies have reported a link between mandibular advancement appliances and maxillary appliances to an increase in the upper airway volume. However, more studies are needed to evaluate the relationship between the changes in the upper airway volume and actual airflow and respiratory capability. The airway volume measurement is important to, preliminary, state if there is an increase in the upper airway after orthodontic treatment. However a change in shape, even with the same volume, can affect the pressure and airflow. In this sense, the pressure drop analysis will allow an answer to those questions
