No paediatric cases and five adult cases of malignancy were detected. All malignant cases presented with other symptoms. Using binary logistic regression, a history of rapid unilateral tonsil enlargement was the only factor found to be significantly associated with malignant outcome. Thirty-three per cent of subjectively larger tonsils were smaller on post-operative histological measurement. Of the cases, 12.1 per cent re-presented with post-tonsillectomy bleeding.<\/jats:p><\/jats:sec><jats:sec id=\"S002221512200216X_sec_a4\" sec-type=\"conclusions\"><jats:title>Conclusion<\/jats:title><jats:p>The authors recommend avoiding histology tonsillectomy for unilateral tonsil enlargement unless \u2018red flag\u2019 signs of malignancy are present, with particular attention to rapid unilateral tonsil enlargement. This study demonstrated discrepancy between clinical examination findings and true tonsil asymmetry; there may be a role for cross-sectional imaging prior to histology tonsillectomy in high-risk patients.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s002221512200216x","type":"journal-article","created":{"date-parts":[[2022,9,28]],"date-time":"2022-09-28T02:49:16Z","timestamp":1664333356000},"page":"1022-1026","source":"Crossref","is-referenced-by-count":8,"title":["Unilateral tonsil enlargement in children and adults: is routine histology tonsillectomy warranted?
