Objective: The aim of this study was to investigate the possible effects of routine hematological parameters on the development and prognosis of idiopathic sudden sensorineural hearing loss in patients applying to our clinic.
Study design: A retrospective clinical study. Setting One academic health center from 2008 to 2014.
Patients and intervention: One hundred forty patients with sudden hearing loss and 132 healthy controls were included in the present study.
Results: Patients having idiopathic sudden sensorineural hearing loss were divided into 2 subgroups based on whether they recovered (complete, partial, and slight recovery) (Group 1; n = 83, 59.3%) or not (Group 2; n = 57, 40.7%) during the follow-up term. Group 1, Group 2, and the controls differed statistically significantly in terms of neutrophil-to-lymphocyte ratio (P = 0.001), platelet-to-lymphocyte ratio (P = 0.001), lymphocytes%(P = 0.001), mean corpuscular hemoglobin (P = 0.019), mean corpuscular hemoglobin concentration (P = 0.015), platelet (P = 0.001), mean platelet volume (P = 0.001), platelet distribution width (P = 0.009), and glucose (P = 0.001). The study groups and the controls did not have any significant difference in terms of other laboratory parameters affecting the prognosis of Idiopathic sudden sensorineural hearing loss.
Conclusions: The results the authors obtained showed that laboratory parameters such as lymphocyte, lymphocyte%, platelet, mean platelet volume, platelet distribution width, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration may be indicative for prognosis and treatment success in groups of patients suffering idiopathic sudden sensorineural hearing loss in whose etiology many factors play a role.
