Coblation tonsillectomy versus cold steel dissection tonsillectomy: a morphological study

Abstract: ObjectiveTo compare the extent of tissue damage produced by conventional cold steel and coblation tonsillectomy.MethodsTwenty patients underwent conventional and 18 underwent coblation tonsillectomy. The removed tonsils were histopathologically evaluated.ResultsAnalgesic use was lower in the coblation group during the early post-operative period. Histological investigation of tonsils removed by the conventional method showed intensive haemorrhage and hyperaemia in the tonsillar capsules, which was not seen in … Show more

“…The burning effect may damage the deep tissue, resulting in local edema and release of inflammatory mediators, thus causing pain (23). Although CT can work at a low temperature (40-70 ℃), with less thermal damage and less local edema, it can also cause muscle and mucosal tears (24). Therefore, there was no significant difference in postoperative pain between the 2 procedures.…”

“…Different from traditional surgical techniques, such as cold steel or electrocautery, a coblation wand can cut tissue and simultaneously stop bleeding by exciting electrolytes within saline to form a focused gas “plasma” at low temperatures (40–60°C) 17 . Thus, coblation tonsillectomy exhibits its advantages, including a short operation time, less postoperative pain, and less damage to surrounding tissues 18,19 …”

“…RFC is a low‐temperature (40–70°C) bipolar radiofrequency electrosurgery technique. Using coblation, the medium is dissociated into free sodium ions, which are responsible for the destruction of intercellular bonds, resulting in tissue dissociation 9 . This technology was firstly introduced in otolaryngology for tonsillectomy.…”
