Abstract: (278 Views)
Background and purpose: Tonsillectomy is one of the most commonly performed surgical procedures in children and is associated with several complications, including pain and bleeding. The aim of this study was to compare two tonsillectomy techniques - LigaSure and cold dissection - in terms of intraoperative outcomes (operation time and intraoperative bleeding) and postoperative complications, including nausea, vomiting, sore throat, ear pain, and bleeding.
Materials and methods: A single-blind randomised clinical trial was conducted on patients scheduled for tonsillectomy at Buali Hospital in Sari. A total of 60 adult and paediatric patients were randomly allocated into two groups using block randomisation and underwent tonsillectomy using either the LigaSure or cold dissection technique. Surgical time was recorded from gag insertion (mouth opening with retractor placement) to completion of the procedure. Intraoperative bleeding was measured using a graded suction system, and all data were recorded individually for each participant. Patients were followed up at 24 hours, 7 days, and 14 days postoperatively, during which tonsillar bleeding, earache, sore throat, and vomiting were assessed.
Results: There were no significant differences between the two groups in terms of age, weight, or gender. The mean operation time was 13.5 ± 2.7 minutes in the cold dissection group and 7.4 ± 1.6 minutes in the LigaSure group, showing a statistically significant difference (P< 0.001). Intraoperative bleeding was 93.2 ± 76.6 mL in the cold dissection group compared with 0.4 ± 0.9 mL in the LigaSure group, which was also statistically significant. Postoperatively, earache was more frequently reported in the cold dissection group at 24 hours, whereas sore throat was more common in the LigaSure group at 7 and 14 days after surgery.
Conclusion: Considering the shorter operative time, reduced intraoperative bleeding, and lower complication rates associated with the LigaSure technique compared with cold dissection, it is recommended that the LigaSure method be preferred for tonsillectomy in children.
