Clinical studies and randomized controlled trials consistently demonstrate that septoplasty effectively relieves nasal obstruction symptoms and improves quality of life compared to baseline and non-surgical management.
The claim is that deviated septum surgery effectively relieves nasal obstruction symptoms. Multiple retrieved studies (such as 1, 2, and 4) provide direct prospective and randomized trial evidence showing significant postoperative improvement in validated nasal obstruction and quality of life scores (like NOSE and SNOT-22) following septoplasty. There are no refuting studies in the provided set.
