Summary

Tonsillectomy using bipolar diathermy resulted in a significantly higher rate of secondary post-tonsillectomy hemorrhage compared to cold dissection. This finding is crucial for surgical technique selection in tonsillectomy procedures.

Area of Science:

  • Otolaryngology
  • Surgical Techniques
  • Patient Safety

Background:

  • Post-tonsillectomy hemorrhage is a significant complication.
  • Comparing surgical methods is essential for optimizing patient outcomes.
  • Cold dissection and bipolar diathermy are common tonsillectomy techniques.

Purpose of the Study:

  • To compare the rates of reactionary and secondary post-tonsillectomy hemorrhage.
  • To determine if cold dissection or bipolar diathermy leads to different hemorrhage rates.
  • To inform surgical practice regarding tonsillectomy complications.

Main Methods:

  • Prospective study of 349 patients undergoing tonsillectomy.
  • Data collected on patient demographics, surgical method, and hemorrhage.

  • Comparison of hemorrhage rates between cold dissection and bipolar diathermy using Chi2 test.

    • Main Results:

    • Overall reactionary hemorrhage rate was 0.3%; secondary hemorrhage rate was 9.2%.
    • Secondary hemorrhage occurred in 12.5% of patients after bipolar diathermy versus 5.5% after cold dissection.
    • The difference in secondary hemorrhage rates was statistically significant (P < 0.05).

    Conclusions:

    • Bipolar diathermy is associated with a significantly higher rate of secondary post-tonsillectomy hemorrhage.
    • Cold dissection may be a safer method regarding secondary hemorrhage risk.
    • Surgical technique choice can impact post-tonsillectomy complication rates.
