Postoperative Pain in Adult Tonsillectomy: Is There Any Difference Between the Technique?

Tonsillectomy is one of the most common surgical procedures performed worldwide. Several techniques have been developed to reduce morbidity and enhance recovery after tonsillectomy. Our study was designed to compare post-operative pain with three different techniques: cold dissection (CD), monopolar-bipolar dissection (MBD) and coblation dissection (CBD). 103 adults were scheduled for elective tonsillectomy from September 2014 to December 2015, and were randomized to CD, MBD and CBD. Post-operative pain was assessed using visual analogue scale (VAS) and Lattinen Test (LT). We did not find significant differences between the groups in the VAS pain scores ( p  > 0.05), except for the first day, when CBD tonsillectomy showed a higher pain score ( p  < 0.05). The differences in LT scores between the three techniques were not statistically significant ( p  > 0.05). Comparison of analgesic consumption between CD, MBD and CBD did not found any significant differences irrespective of the technique used. When first and second week after surgery were compared, differences in analgesics requirements were statistically significant ( p  < 0.05). Seventeen cases (16.5%) of secondary haemorrhage were reported, but there were no statistical differences in the rate of postoperative bleeding between the three groups ( p  > 0.05). We conclude that in our study comparison of the three techniques, CD, MBD and CBD, did not show significant differences in the post-tonsillectomy pain scores and bleeding rate.
