[Cost-benefit analysis of the anatomo-pathological study of tonsillectomy specimens in the pediatric population]

To study the cost-benefit of the histological examination of tonsilar samples, we evaluated 567 cases (547 routine and 20 nonroutine cases) of patients under 14 years of age, operated between 1st January 1996 and 30th November 2000. There were 2 routine cases (0.3%), and 6 nonroutine cases (30%) with a diagnosis different to follicular hyperplasia. In this way, our clinical preoperative sensitivity was 75% and specificity 97%. The average cost per case at our Centro to study the tonsilar samples was 30$. We conclude that the histological examination of tonsilar specimens is economically worth only in nonroutine cases, although additional factors (e.g. training of residents of Pathology and the quality control of the institution must be taken into consideration.
