Exposure of the distal internal carotid artery at the level of the second cervical vertebra required manoeuvers such as division of digastric muscle or mandibular subluxation. These increase the exposure but may not provide adequate access and are associated with significant cranial nerves or temporal mandibular joint complications. Vertical Ramus Osteotomy (VRO) provided access of the internal carotid artery (ICA) up to the base of the skull, with low incidence of cranial nerve injury temporo-mandibular joint (TMJ) pain and no preincision preparation. We report two cases in which vertical division of the mandibular ramus provided access of the ICA up to the base of the skull. Preoperative Duplex Scan examination and in the second case the arteriography revealed ICA preocclusive stenosis within 1.5 cm of the skull base. VRO was performed trouhgh a standard neck incision and miniature titanium plates were used to reapproximate the mandible after vascular procedure. There were no death, cranial nerve injury, mandibular nonunion, malocclusion or TMJ pain. We found that VRO is useful when carotid artery pathology extends beyond the usual field of exposure, avoiding nerve injury or TMJ lesion and requires no additional pre-incision preparation.
