Surgical technique and post-tonsillectomy hemorrhage: a single institution's retrospective study

Area of Science:

• Otolaryngology
• Surgical Complications
• Hemorrhage Management

Background:

• Post-tonsillectomy hemorrhage is a frequent complication.
• Surgical techniques may influence hemorrhage rates.

Purpose of the Study:

• To compare the incidence and timing of post-tonsillectomy hemorrhage between cold dissection and microscopically assisted bipolar tonsillectomy.
• To evaluate the need for surgical hemostasis in each group.

Main Methods:

• Retrospective analysis of 1007 patients undergoing tonsillectomy.
• Comparison of cold dissection versus microscopically assisted bipolar tonsillectomy.
• Data collection on hemorrhage occurrence, timing, and need for hemostasis.

Main Results:

• Overall hemorrhage rate was 11.5%.
• Cold dissection: 10.9% hemorrhage, 5.9% required hemostasis.
• Microscopic bipolar: 13.9% hemorrhage, 7.9% required hemostasis.
• No statistically significant difference in hemorrhage prevalence or timing between methods.
• First bleeding episodes occurred around postoperative day 5-6 for both techniques.

Conclusions:

• Neither cold dissection nor microscopically assisted bipolar tonsillectomy showed a significant difference in post-tonsillectomy hemorrhage rates.
• Individualized institutional statistics and standardized documentation protocols for hemorrhage are recommended.
• Findings may inform recommendations for in-hospital stay duration.
