Background: Tonsillectomy is a commonly performed surgery in the world. The common indicators of tonsillectomy include recurrent tonsillitis, recurrent peritonsillar abscess, and obstructive sleep apnea. Tonsillectomy may be followed by many complications like dehydration, vomiting, nausea, bleeding, pain, and infections, among which bleeding is the most serious complication.
Objective: The study aimed to evaluate the incidence and possible risk factors post-tonsillectomy hemorrhage.
Methods: This prospective descriptive study included 100 patients (54 females and 46 males) aged between 5-30 years from the otolaryngology unit in Ad-Diwaniah hospital, Ad-Diwania governorate, Iraq, between May 2017 and October 2019. T Inclusion criteria: recurrent tonsillitis, tonsillar enlargement affecting sleep pattern, obstructive sleep apnea syndrome, and immunoglobulin-A nephropathy. Post-tonsillectomy, the hemorrhage was classified based on the bleeding time postsurgery. If bleeding occurred on the first day (24 hours) after operation, it was called primary post- tonsillectomy bleeding, and post that, it was termed
secondary post-tonsillectomy bleeding.
Results: Of 100 patients, only 11 developed post-tonsillectomy hemorrhage (11%). Primary post-tonsillectomy bleeding occurred in eight patients, whereas secondary post- tonsillectomy bleeding occurred in three patients. Nine male and two female patients developed post-tonsillectomy hemorrhage. Primary post-tonsillectomy hemorrhage occurred in those with obstructive sleep apnea, recurrent tonsillitis, and history of non-steroidal
anti-inflammatory drug use, smoking, and obesity and secondary posttonsillectomy hemorrhage occurred in those with smoking history, obesity, obstructive sleep apnea, and recurrent tonsillitis.
Conclusion: Older age group, male sex, recurrent tonsillitis, and smoking history are pivotal factors of post tonsillectomy hemorrhage.
