Active clinical trials for "Nasal Obstruction"

Nasal obstruction is a very subjective sensation but it's also a frequent reason of consultation. Two specific questionnaire NOSE and RhinoQOL were validated; but rhinomanometry value is still a question to debate. As well as the difference between acoustic rhinometry and rhinomanometry. Usually nasal obstruction due to a septal deviation is treated by septoplasty. If the anatomic result can be proved true, the patient's felt would be unsuccessful. The aim of this study is to assess the impact of septoplasty on the nasal obstruction, objectively by rhinometry and subjectively by questionnaire.

Currently effective antivials for influenza treatment are two influenza viral neuraminidase inhibitors, oseltamivir (Tamiflu) and zanamivir (Relenza). Resistance to these drugs is reflected by reduced susceptibility of viral neuraminidase to these drugs. The hypothesis is that the signal ratio of two reagents (with or without a single concentration of the drug) correlates the IC50 value, an accurate measurement of drug resistance but impractical for clinical use.

The term adenoids describes lymphoid tissue on the superior and posterior walls of the nasopharynx, and their hypertrophy is a common condition of childhood. When enlarged, adenoids can obstruct the nasopharyngeal airway and cause mouth-breathing, hyponasal voice, and snoring. In more severe cases, obstructive sleep apnea (OSA) may result, which carries potential risk of neurocognitive disturbance, growth failure, and heart-lungs disease. Adenoid hypertrophy can also be associated with otitis media with effusion, possibly through Eustachian tube dysfunction or chronic adenoidal infection. Methods for identification of adenoid hypertrophy include the clinical history, examination, imaging (eg, plain lateral x-ray), or by nasal endoscopy witch enable direct visualization of the nasal cavity with dynamic evaluation of any nasal airway obstruction. Objectives : The aim of this study is to prospectively examine invasive and non-invasive office procedures to assess adenoids hypertrophy, including clinical history, x-ray imaging, and nasal endoscopy. Methods : Prospective, observational study in pediatric patients aged 2-18 that will be referred to the otolaryngology pediatric 'Clalit' clinic in Haifa after x-ray imaging and an informed consent. Nasal Obstruction Index (NOI) The NOI questionnaire for history and physical exam will be evaluated at the clinic, as described by Paradise grading system. Plain lateral x-rays Plain lateral X-rays of the patients will be evaluated only if the patients had them at the time of referral. Adenoidal obstruction will be assessed by Fujioka's Adenoid-Nasopharynx ratio. Fiberoptic nasal endoscopy (FNE) Fiberoptic analysis will be done as an office procedure using a 2.4mm Storz nasal flexible endoscope following an application of Lidocaine gel locally into the nostril and on the endoscope distal end. Adenoidal obstruction will be assessed by Parikh grading system.

We intend to study, in depth, the quantitative and qualitative properties of nasal respiration in sleep-disordered breathing and sleep apnea and its relation to (CPAP) treatment with the final goal of improving patient outcome. To do this we will temporarily alter patients' nasal airflow during monitored sleep to lower CPAP air pressure, making CPAP treatment more acceptable to the patient. Additionally we plan to implement highly advanced computerized modelling in collaboration with the OSASMOD research consortium at St. Olavs Hospital/NTNU and SINTEF to predict the results of our alterations and ultimately, to use these predictions to improve both the planning and the outcomes of nasal surgery.

Nasal continuous positive airway pressure can cause nasal side effects which can compromise compliance to therapy. Humidifiers can attenuate this effect. However, the mechanism by which humidified CPAP alleviates nasal symptoms has never been assessed objectively in OSA patients. Therefore, the purpose of this study is to examine the effect of humidified CPAP on nasal airway physiology with combined measurements of nasal resistance and level of inflammatory markers. The investigators' hypothesis is that the addition of heated humidification in CPAP decreases nasal airway resistance and nasal mucosal inflammation markers and thus, ameliorates nasal symptoms of OSAS patients.

Evaluation of long-term (5-year) quality of life after nasal airway obstruction treatment with the Aerin Vivaer Stylus

This is Prospective Basic Science Study whose aims are as follows: To determine the effect of Filtering Facepiece (FFP3M) respirators on eustachian tube function and hearing To evaluate the extent to which FFP3M respirators attenuate speech in decibels The outcome measures are as follows: Changes in baseline pure tone audiometry and tympanometry post intervention. SNOT-22 Questionnaires before and after use of respirator ETDQ7 questionnaire Measurement of speech attenuation in decibels.

Demonstrate the therapeutic clinical equivalence of two mometasone nasal sprays in the relief of the signs and symptoms of perennial allergic rhinitis, in term of changes at week 8 from baseline of Total Nasal Symptom Scores (TNSS).

Commercially-available internal nasal stents placed inside the nostril should produce decreased nasal obstruction detectable subjectively (volunteers will fill out a survey) and objectively (degree of obstruction will be measured with a rhinomanometer which measure resistant of airflow while breathing through nose).

Recent clinical findings of research at Trondheim University Hospital suggest that surgical correction of the nose septum in addition to volume reduction of the nose cavity may be beneficial in patients who suffer from both nose obstruction and obstructive sleep apnea syndrome(data not yet published). This study aims to compare nose obstruction prevalence in sleep apnea patients and the general population
