Case Report

A 25-year-old patient was admitted to the emergency room presenting frontal headaches, without improvement, despite the use of pain killers. The patient had suffered a traumatic brain injury (TBI) 30 days before, when he collided frontally with another driver. After a skull radiography, the presence of a foreign body was observed in the frontal sinus. A cranial computed tomography (CT) scan found that it was a tooth ([Fig. 1]). The patient underwent surgical treatment ([Fig. 2]) for the removal of the tooth. His evolution was satisfactory, and the patient was asymptomatic upon discharge.

Fig. 1 Pre-operative images. (A, B): radiograph (AP and lateral view respectively) showing the presence of the tooth in the frontal sinus; (C): sinking present in the left frontal sinus; (D-F): axial CT scans (bone window) showing the presence of the tooth within the left frontal sinus.

Fig. 2 Operative findings. (A-C): approach by eyebrow (step by step) to remove the tooth; (D): tooth after withdrawal.

Traumatic brain injury caused by non-missile penetrating objects is unusual, and has been described in case reports in the literature,[1] and in some literature reviews that corroborate our management.[2] The most likely justification for this trauma would be the fact that the patient was not wearing a helmet during the frontal collision, and unfortunately the other driver's tooth pierced his frontal sinus. To the best of our knowledge, no similar reports can be found in the literature.
