The infection follows the thermal damage with the use of electrosurgical techniques by the enzyme and bacteria containing saliva, leading to PTH.17 The use of electrosurgery was associated with a higher incidence of PTH as reported by different studies.1,12,18 Coblation technique for tonsillectomy is currently used by a more experienced surgeon and more often in paediatric tonsillectomy, which may be the reason for lack of PTH in this group. This evidence concerns the gene PTH and infection.
