The efficacy of tonsillectomy in chronic tonsillitis patients as demonstrated by the neutrophil-to-lymphocyte ratio

Abstract

AbstractObjectives:Adenoidectomy and tonsillectomy are the oldest surgical procedures. The neutrophil-to-lymphocyte ratio is an inflammatory marker. This study aimed to investigate neutrophil-to-lymphocyte ratios in chronic tonsillitis patients and to determine whether this ratio reflects the pre- and post-operative inflammatory status in these patients.Methods:Patients and healthy individuals were assigned to four groups: the adenoid hypertrophy, adenotonsillar hypertrophy, chronic tonsillitis and control groups. The neutrophil-to-lymphocyte ratio was calculated for each patient before surgery and one month post-surgery. Pre- and post-operative white blood cell, neutrophil and lymphocyte counts and neutrophil-to-lymphocyte ratios were compared both within and between groups.Results:Pre- and post-operative neutrophil-to-lymphocyte ratios were significantly higher in the chronic tonsillitis group than in the adenoid hypertrophy and adenotonsillar hypertrophy groups (p< 0.01 andp< 0.05, respectively). In the chronic tonsillitis group, post-operative neutrophil-to-lymphocyte ratios were significantly lower than pre-operative ratios (p= 0.045). The pre-operative neutrophil-to-lymphocyte ratio was significantly higher in the chronic tonsillitis group than in the adenoid hypertrophy, adenotonsillar hypertrophy and control groups (p= 0.000). In contrast, there was no significant difference in post-operative neutrophil-to-lymphocyte ratios among all groups (p= 0.584).Conclusion:The neutrophil-to-lymphocyte ratio measurement can be used in chronic tonsillitis patients as an effective auxiliary method for determining the necessity and timing of tonsillectomy and post-operative follow up, thereby helping prevent complications due to delayed or inadequate treatment.
