ABSTRACT
Objective To explore the application of utrasonic technology-assited microsurgery resection of ventral or ventrolateral spinal schwannomas.Methods Forty patients with ventral or ventrolateral spinal schwannomas were treated by CUSA-assited microsurgery.Results The tumors were totally resected suc-cessfully acompanied by minimal blood loss and adjacent structures could avoid damaged.Preoperative and postoperative magnetic resonance imaging demonstrated complete resection in all cases.Neurological func-tions had good recovery.With follow-up of 3 months to 3 years,there was no instability of the spine or any recurrence.Conclusion utrasonic technology-assited microsurgery resection of ventral or ventrolateral spi-nal schwannomas by posterior approach appears a safe,efficient mini-invasive surgical approach,without mechanical or heat injury.
ABSTRACT
objective To explore the application of navigation-assited microsurgery resection of posterior fossa solid hemangioblastoma.Methods The data of 16 patients with posterior fossa solid hemangioblastoma treated by navigation-assited microsurgery were analyzed retrospectively,compared with 19 patiems treated by microsurgery who suffered the same disease in the similar location(control group).Results The tumors were totally resected successfully acompanied by minimal blood loss and shortening of the operation time,compared with the control group.Manipulation and removal of these tumors were actually easier,in addition,adjacent structures can avoid damage.Conclusions Navigation-assited microsurgery is useful technique to surgical resection of fossa solid hemangioblastoma by significantly reducing blood loss at the time of surgery and operation procedure time,avoiding damage to the adjacent structures,and reducing the surgery complications and mortality.
