ABSTRACT
This study investigated the effect of tonsillectomy on the immunity of patients and the level of immunoglobulins after tonsillectomy in 157 patients. It was found that there was significant fall on the base line serum level of IgG, postoperatively, while the IgM and IgA were not affected much. The fall in IgG was transient and did not affect the immunity of the individuals. It was also found that the group of patients having massively enlarged tonsils did not show marked rise in the level of immunoglobulins, on the contrary, the levels were found lower than in the other 2 groups having mild enlargement of tonsils. During the follow up after tonsillectomy, the patients did not have any significant episode of sore throat or upper respiratory tract infection
