Abstract:
Objective To investigate the micro-anatomical approach to resect both intracranial and extracranial jugular foramen tumors in one-stage. Methods With the aid of surgical microscope, fifteen cadaver heads were used to study the microsurgical anatomy of high cervical part and jugular foramen, measure relative data. Results Detailed dissection was performed on high cervical part between the 1st cervical vertebra and the 4th cervical vertebra, resect foramen processus transversi of the 1st cervical vertebra, free vertebral artery 2nd and 1st cervical vertebra segment and horizontal segment. The jugular tubercle, jugular tunisia and part of the occipital condylus was drilled away as much as possible, total exposure of lateral semicircular canal was completed after the removal of the mastoid revealed labyrinthinem. Then the sigmoid sinus and jugular bulb were skeletonized. The vertical of segment of facial nerve was fully skeletonized to study the necessity of the facial nerve translocation. Full exposure to the sigmoid sinus, open jugular foramen. JF areas expanded, and the measured parameters revealed. The distance was (29.65 ± 3.24)mm from mastoidalec to oncentrated focus of condyle (10.18 ± 0.81)mm from hinder margin of condyle to endostoma of hypoglossal canal. The left distance was (6.8 ± 0.35)mm from jugular foramen to perpendicular part of facial nerve, right was (4.6 ± 0.33)mm. Conclusions Total exposure of JF can be achieved through the approach we described, and will enable the facial nerve, cochlea, and the structure of the vertebral artery to be performed. Both intracranial and extracranial tumors can be removed in a one-stage procedure related to anatomical parameters. Improve the cure, reduce complication and lower mortality.
