Factors affecting secondary post-tonsillectomy hemorrhage: a case—control study

Abstract

Background: Tonsillectomy is one of the commonest otolaryngological procedures performed. Multiple reports have demonstrated the safety of ambulatory (outpatient) pediatric Tonsillectomy, however Post-tonsillectomy hemorrhage remains the most serious complication of tonsillectomy. Patients and methods: In this work, we analyzed different parameters including patient’s age, gender, type of surgery “Tonsillectomy or Adenotonsillectomy”, technique “Cold dissection or Bipolar”, evidence of tonsillar bed infection and pre-operative hemoglobin level in two groups of patients indicated for tonsillectomy. One group of 80 patients didn’t suffer from posttonsillectomy bleeding as a control group; the other of 20 patients having secondary post-tonsillectomy bleeding. Results: According to our statistical analysis and data, no significant difference between the two groups regarding the occurrence of secondary post-tonsillectomy in the following parameters: patient’s age, gender, type of surgery “Tonsillectomy or Adenotonsillectomy” and preoperative hemoglobin level. Conclusion: However there was higher incidence of secondary post tonsillectomy bleeding in patients operated by bipolar scissors. Also evidence of tonsillar bed infection raises the possibility of secondary post-tonsillectomy bleeding occurrenc.
