Nasal Obstruction Compared by Rhinomanometry & Nasal Inspiratory Peak Flow

Status Recruiting

Clinical Trial Summary

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.

Clinical Trial Description

The nasal cavity is used to heat, humidify and purify the air before entering other parts of the respiratory system. Other functions of the nose include in particular olfactory, immune, reflex, or sexual functions. Proper airflow through the nasal cavity is essential for all nasal functions; anatomical or flow changes can significantly affect nasal functions. Endoscopic transnasal surgical approaches are modern, mini-invasive methods, enabling the solution of pathologies in the area of the cranial base, through the nasal cavity. The advantage of this technique is the absence of external incisions and scars and significantly better cosmetic effect, these methods also offer very good clarity and illumination of the operating field. The main disadvantage is the risk of affecting the functions of the nose. To create a transnasal approach to the skull base, it is necessary to perform lateralization of middle turbinates, resection of the anterior wall of the sphenoidal sinus, and resection of the posterior part of the nasal septum. These interventions are necessary for a good overview and manipulation in the operated area, however, they can lead to postoperative changes in the physiological functions of the nasal cavity, especially loss of smell, and taste, altered airflow through the nasal cavity, mucociliary transport disorders, nasal obstruction, crusting or drying mucous membrane. All these adverse changes significantly affect the patient's quality of life. As a standard, rhinomanometry is used to measure nasal patency before and after surgery. A modern new method is measuring the patency of the nasal cavity using an NPIF (nasal peak inspiratory flow) device, which has significantly lower acquisition costs, is easy to use, and, above all, fast. The disadvantage is that the examination is less detailed, the result is the amount of air flowing in l/min through the nasal cavity. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
