Data on age, indications for surgery, preoperative and intraoperative clinical findings, and final pathology results were collected.

After study inclusion and exclusion criteria were met, a review of the literature yielded 3, 724 pooled tonsillectomy cases, with no case of unsuspected occult malignancy reported in the literature. The number needed to screen combining our series with the reported literature was 3, 904. The financial impact of routine histopathological analysis at our institution was determined to be CAD $3308 per year.</p> </sec> <sec id="lary25152-sec-0005" sec-type="section"> <title>Conclusion</title> <p>Routine pathological analysis of tonsil specimens recovered from surgery performed for benign indications, in the absence of any suspicion preoperatively for malignancy, is not supported by current evidence and is not financially sound.
