Mandibular alveolar neurovascular bundle injury associated with impacted third molar surgery.
Inferior alveolar neurovascular bundle (IANB) injury is one of the most common complications of third molar removal and involves important medicolegal issues. An accurate preoperative radiographic assessment of surgical difficulty is necessary to correctly plan the removal of impacted third molars and to estimate the risk of IANB injury. Therefore, the preoperative knowledge of the exact location of the third molar roots in relation to the mandibular canal is mandatory. A direct contact between the tooth and neurovascular bundle is suggested by a radiotransparent band across the roots of the impacted third molar on panoramic radiograph. We present the management of a patient with IANB damage associated with third molar surgery.
