Does Septoplasty Affect Hemoglobin and Erythropoietin Levels in Patients With Nasal Septal Deviation?
1Department of Otorhinolaryngology.
Aim:
To investigate the effect of septoplasty in patients with nasal septum deviation (NSD) on erythropoietin (EPO) and hemoglobin (Hgb) levels.
Methods:
Between 2017 December and 2018 May, 47 patients with NSD who underwent septoplasty in Adiyaman University Medical Faculty Department of Otorhinolaryngology included in this prospective study. The changes in EPO and Hgb levels were studied before and 3 months after the surgery.
Results:
The mean age of the patients studied was 30.7 ± 9.9. 31 of the patients were male and 16 were female. Pre- and post-operative 3rd month mean EPO levels of the patients were 11.45 ± 4.9 Mu/mL and 11.39 ± 6.02 Mu/mL, respectively. When these values were analyzed, no statistically significant difference was found (P = .93). Pre- and post-operative 3rd month mean Hgb levels were 14.6 g/dL, and 14.6 g/dL, in turn. When these values were analyzed, no statistically significant difference was found (P = .68).
Conclusion:
According to these results, the author can say there is no statistically significant relationship between NSD and EPO or Hgb. Therefore, this issue will be enlightened with future studies including more patients and objective tests evaluating nasal patency.

Let us consider a dataset containing the number of unsold cupcakes in five shops: 10, 15, 8, 7, and 10. Initially, calculate the sample mean. Then calculate the deviation, or the difference, between each data value and the mean. Next, the absolute values of these deviations are added and divided by the sample size to...
