Effect of Deviated Nasal Septum on Mean Platelet Volume: A Prospective Study

In E.N.T clinical practice, patients with nasal obstruction due to deviated nasal septum is a common presentation. Nasal airway obstruction is a common cause of upper airway obstruction further leading to obstructive and hypoxic manifestations. Mean platelet volume (MPV) levels increase in hypoxic conditions. MPV is one of the platelet activation index which reflects the platelet production rate. Present prospective study conducted in the department of Otorhinolaryngology and Head and Neck surgery, Gandhi Medical College and Hamidia Hospital, Bhopal, on 63 patients with the clinical evidence of DNS and 63 healthy age matched subjects as control group, aimed to evaluate the relationship between MPV levels and nasal obstruction due to deviated nasal septum (DNS). The diagnosis of patients with DNS was based on anterior rhinoscopy and endoscopic nasal examination. Blood samples were collected before surgical correction. In present study, the authors found that there is preponderance of DNS in the age group of 25-45 years being the most active age group, males having the higher incidence. Majority of cases of DNS being left sided and of obstructed type. MPV were significantly higher in patients with DNS than the control group. Among the cases MPV being higher in females and in the impacted type of DNS. Present study reemphasized the concept that MPV is increased in chronic nasal obstruction due to DNS and this increase is in accordance with the severity of DNS.
