ObjectivesThere is no consensus on the optimal technique to decrease post-tonsillectomy morbidity. Histopathological analysis can estimate collateral tissue damage. This study compared histological findings for tonsils removed by cold or electrocautery dissection and their relationship with post-operative complications.MethodsTwo adult out-patient groups were included in the study: 37 who underwent cold dissection and 37 who underwent electrocautery dissection. Histological analysis was used to assess tissue damage.ResultsTissue damage was significantly higher in the electrocautery dissection group (p = 0.002), as were the number of emergency department visits (p = 0.01) and the need for supplemental analgesia (p = 0.013). Patients in the cold dissection group experienced less pain (p = 0.001) and fewer secondary haemorrhage episodes.ConclusionCold dissection produces less tissue damage, which is associated with lower incidence of complications. This study suggests that cold dissection is the technique of choice for tonsillectomy.
