  • Title: Histological analysis of tonsillectomies: relationship with surgical technique, post-operative pain and haemorrhage.
    Author: Magdalena ML, Solé A, Blanco V, Rodrigo JP.
    Journal: J Laryngol Otol; 2016 Dec; 130(12):1142-1146. PubMed ID: 27830635.
    Abstract:
    OBJECTIVES: There 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. METHODS: Two 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. RESULTS: Tissue 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. CONCLUSION: Cold 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.
