Title: Microsurgical anatomy of the suboccipital transcervicojugular approach to the jugular foramen region
Abstract: Objective To describe a minimally invasive approach to resection of extensive jugular foramen tumors at one-stage. Methods With the aid of surgical microscope, the microsurgical anatomy and the exposure of the suboccipital-transcervicojugular approaches were investigated in 10 cadaveric head-neck specimens of adults embalmed with formalin. Results The posterior fossa can be reached through suboccipital approach, the structures in infratmporal fossa can be exposed directely through the corridor between the atlas and mandibular ramus. The jugular foramen can be exposed after removal of the mastoid process and the petrous bone under the labyrinth superiorly and by resection of jugular process posteriorly. The rectus capitis lateteralis is the most important landermark, posterior to it, the vertebral artery and its accompanying venous complex within the suboccipital triangle can be identified, anterior to it are carotid artery, internal jugular vein, lower cranial nerves and sympathetic trunk. Conclusion The suboccipital-transcervicojugular approach can expose the jugular foramen region sufficiently, and offer advantages in preventing labyrinth,cochlea, facial nerve and vertebral artery from unecessary injury.
