Incidence of Pseudoaneurysms After Third Molar Extractions: A Systematic Review With a Proposed Algorithm of Treatment

Purpose: The objective of this study is to systematically evaluate the existing evidence on the prevalence and incidence of pseudoaneurysms following third molar extractions. Methods: The study protocol was developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols, and it was registered with the International Prospective Register of Systematic Reviews under registration number CRD42024578219. Results: Our search strategy yielded 388 articles and all were independently reviewed by two authors for eligibility. Of these, 366 were excluded based on the title and abstract. Twenty-two articles were assessed for eligibility, and 13 studies were excluded as they did not meet the inclusion criteria. Finally, a total of 9 studies met the criteria for inclusion, and they were critically reviewed. Conclusion: Pseudoaneurysms following third molar extractions are rarely encountered; however, oral surgeons should remain vigilant for their potential occurrence. Particular attention should be given if a patient presents with severe intraoral haemorrhage, facial oedema and nasal epistaxis. It is essential for oral surgeons to be familiar with the management protocol as outlined in the proposed algorithm to ensure prompt and effective intervention.
