Impact of Septoplasty on Mean Platelet Volume Levels in Patients With Marked Nasal Septal Deviation

Nasal septal deviation (NSD) is a very common cause of recurrent and chronic nasal obstruction. Chronic nasal obstruction leads to increased upper respiratory tract resistance, and also upper respiratory tract resistance leads to chronic hypoxia and hypercarbic because of alveolar hypoventilation. Chronic hypoxia and hypercarbia show tendency for hypercoagulopathy. Mean platelet volume (MPV), the most commonly used measure of platelet size, is a potential marker of platelet reactivity. Large platelets that contain more dense granules are enzymatically and metabolically more active and have greater prothrombotic potential. In previous studies, increased MPV was demonstrated in hypertension, unstable angina pectoris, myocardial infarction, stroke, and obstructive sleep apnea. We aimed to determine whether MPV levels are elevated in patients with marked NSD (MNSD) compared with healthy controls. In addition, we tried to find out the effect of nasal septoplasty on MPV levels. We found that the MPV levels were significantly higher in the MNSD group than in the control healthy group, and also we found that MPV levels were significantly decreased in the MNSD group after septoplasty operation. In conclusion, in our knowledge, this is the first study investigating MPV levels in patients with MNSD. Increased platelet activation may be related to increase the cardiovascular risk in patients with MNSD. Our results suggest that MPV, a determinant of platelet activation, is elevated in patients with MNSD, and the increase in MPV levels of the cases with MNSD could be treated by septoplasty.
