Cold Dissection Tonsillectomy and Radiofrequency Tonsil Ablation: A Prospective Comparative Study
Dubai Medical Journal
Over the last few years, various techniques have been proposed for performing tonsillectomy in an attempt to lower the morbidity of this surgery. However, controversy still exists regarding the optimal technique involving the least postoperative morbidity. More recently, temperature-controlled radiofrequency has been introduced as a much more effective and safe device for tonsil reduction. Objective: To compare the effectiveness of conventional tonsillectomy versus radiofrequency tonsil
... ency tonsil ablation with respect to duration of surgery, amount of intraoperative bleeding, recovery time, and postsurgical pain. Materials and Methods: 60 patients were randomly divided into two groups. One group underwent conventional cold ablation tonsillectomy while radiofrequency tonsillectomy was performed in the second group. Duration of surgery, amount of intraoperative bleeding, recovery time, and postsurgical pain (using the Wong-Baker FACES Pain Rating Scale ® ) were measured. All patients were followed for 24 months. Results: Comparing the radiofrequency tonsillectomy group to the cold dissection tonsillectomy group, the mean duration of surgery was 6.92 versus 18 min, the amount of intraoperative bleeding was 2.75 versus 39.88 mL, and the difference on the postoperative pain scale between the two groups was statistically significant (p < 0.005). There was no recurrence of tonsillitis episodes in either of the 2 groups during the 2-year follow-up period. Conclusion: After adequate training, the radiofrequency technique is beneficial to both the surgeon and the patient, including the possibility to excise tissue and coagulate bleeding vessels with the same device. Postoperative morbidity and complications are lower as compared to the conventional cold dissection technique.
