Nasal Obstruction and Olfactory Losses

Nasal Obstruction

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.

Effect on Sleep of Surgical Treatment of Severe Nasal Obstruction

Sleep ApneaObstructive Sleep Apnea1 more

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.

Upper Airway's Pressure Drop Analyses After Mandibular Advancement and Maxillary Expansion

ApneaAirway Obstruction3 more

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

Novapak Prospective Observational Clinical Trial

Nasal Airway Obstruction

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.

Outcome Analysis in Septorhinoplasty

RhinoplastyNasal Obstruction1 more

A prospective observational cohort study that measures pre- and postoperative outcome of septorhinoplasty by means of patient-related outcome measures (PROMS: NOSE, FACE-Q, Utrecht Questionnaire, SCHNOS and BDDQ-AS) as well as with functional tests (NAR, AR, PNIF).

Computational Modeling of Cleft Lip Nasal Deformity and Assessment of Nasal Function and Treatment...

Cleft Lip and NoseNasal Obstruction

The purpose of this study is to use computers to simulate airflow in 3D construction of your nasal cavity generated from cone beam CT images. The results from computer simulations will help researchers identify the severity of cleft-induced nasal dysfunction and assess the impact of current treatment in restoring breathing function. The ultimate goal is to improve post-surgery outcomes to restore nasal breathing function to normal levels.
