Objective: Nasal septal deviation is a common disorder of the nose and patients commonly visit
clinics with complaints of nasal obstruction. As a result of nasal obstruction, patients are exposed to
snoring, which causes hypoxia. Hypoxia leads to chronic inflammation, oxidative stress and endothelial
dysfunction. Platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) are new markers
for inflammation. In this study we have aimed to study the relationship between hypoxia, PLR, NLR and
other platelet markers in patients with septum and external deviations.
