Post-tonsillectomy bleeding from unknown coagulation disorders is rare. However, even with normal tests, persistent bleeding warrants a detailed coagulation factor analysis to rule out underlying disorders.

Area of Science:

  • Otorhinolaryngology
  • Hematology

Background:

  • Postoperative hemorrhage is a known complication of tonsillectomy and adenotonsillectomy.
  • Identifying the underlying causes of hemorrhage is crucial for patient management.

Purpose of the Study:

  • To evaluate the incidence and clinical features of previously unidentified coagulation disorders in patients experiencing post-tonsillectomy or adenotonsillectomy hemorrhage.
  • To determine the diagnostic value of routine coagulation tests and patient history in identifying these disorders.

Main Methods:

  • Retrospective study of 6,966 patients undergoing tonsillectomy or adenotonsillectomy.
  • Analysis of 201 patients who experienced postoperative hemorrhage.
  • Review of clinical features and coagulation status.

Main Results:

  • Hemorrhage secondary to unidentified coagulation disorders is extremely rare following tonsillectomy/adenotonsillectomy.
  • Normal coagulation values and insignificant patient history do not exclude the possibility of a coagulation disorder.
  • Diffuse, persistent, and bilateral bleeding, when not attributable to other causes, necessitates further investigation.

Conclusions:

  • While rare, unidentified coagulation disorders can cause post-tonsillectomy hemorrhage.
  • A high index of suspicion is required for diagnosis, even with normal initial assessments.
  • Rapid and detailed analysis of coagulation factors is recommended for persistent, unexplained bleeding.
