Aim and background: Third molar extractions are performed quite frequently in a clinical setup. However, complications associated with surgery of impacted mandibular third molars reporting pseudoaneurysm formation are extremely rare. In the present case report, we discuss a case of an aneurysm associated with a wisdom tooth in the lower left region of the jaw in a middle-aged patient. Case description: A 30-year-old male reported a chief complaint of pain in the lower left region of the jaw. On oral examination, a partially erupted third molar was seen associated with bleeding on probing. A computed tomography angiography (CTA) of the neck was done, which revealed left facial artery saccular aneurysmal dilatation. An emergency embolization was planned. Under general anesthesia, in the first half, the department of vascular intervention (DVI) radiology team performed the carotid angioplasty with embolization which was followed by the maxillofacial team, who performed a surgical extraction of the partially erupted third molar in the left quadrant. He was then shifted to the general ward and discharged the next day in an overall stable condition. Conclusion: Even though traumatic aneurysms are uncommon in the facial region; it is essential to include this lesion in the differential diagnosis of soft tissue lesions in order to prevent severe bleeding complications. Clinical significance: Oral surgeons must promote the spread of awareness regarding routine dental visits for early diagnosis.
