Quantitative assessment of T. and B lymphocytes population pre and post tonsillectomy

T and B lymphocytes were quantitatively estimated in the peripheral blood of 50 patients pre tonsillectomy and three months postoperatively by E-rosette and E-A rosette tests, respectively. There was a statistically significant decrease in E-rosette and E-A rosette percentage postoperatively. Age and sex of patients had no statistical significant effects on the results. The results may give an idea about the importance of the tonsils as a tissue sharing in the immunological mechanism of the body and this may direct the attention of the ENT surgeon to put the immunological factor in consideration during taking the decision of tonsillectomy
