What this Trial Is About
Nasal obstruction (NO) affects about 30% of people and commonly leads to visits in ear, nose, and throat care. Most cases stem from inflammation like allergic rhinitis or chronic rhinosinusitis, while some are due to structural issues such as septal deviation or enlarged turbinates. NO can significantly reduce quality of life and sense of smell, and it may worsen conditions like asthma and sleep apnea. Various questionnaires and objective tests like anterior active rhinomanometry (AAR) help assess the severity and impact of NO. This observational study evaluates the reliability of preoperative anterior active rhinomanometry as an independent tool to confirm the need for endonasal surgery in patients with nasal obstruction. AAR measures nasal airway resistance using pressure sensors while the patient is seated or lying down. The study focuses on patients scheduled for surgery such as septoplasty, turbinoplasty, or rhinoplasty and who have had preoperative AAR without nasal decongestants. Participants will undergo AAR before surgery, and researchers will compare AAR results with symptoms and quality of life scores from questionnaires like the NOSE and SNOT-22. Postoperative improvements in these scores, AAR measurements, and sleep apnea indices will be evaluated at three months after surgery. The study aims to better understand how well AAR alone can guide surgical decisions and assess patient outcomes over time.
