To investigate the treatment results for the different surgical approaches for intraspinal tumor in lumbar spine. We retrospectively reviewed data for 51 patients with intraspinal tumors who were treated with surgery. We used the navigation system (group A) or traditional method (group B) to guide the surgery. Through the comparison of group A (22 patients) and group B (29 patients), we found some differences between the two groups, such as their total resection rate, the placement of pedicle screws, the mean operating time, intraoperative operation loss, JOA scores. In group A, the total resection rate was 95.45%. One hundred and ten pedicle screws were implanted, and no screw injured the nerve tissues or blood vessel; the placement of 94.55% of the pedicle screws was excellent. In group B, the total resection rate was 86.28%. A total of 134 pedicle screws were implanted, including five screws that injured nerve tissues or blood vessels; the placement of 87.31% of the pedicle screws was excellent. The postoperative symptoms were significantly improved in the two groups, and there were no deaths. The operation times were significantly lower in group A than in group B (P < 0.05), and the intraoperative operation loss was significantly lower in group A than in group B (P < 0.01). Additionally, the postoperative improvement in percent evaluated by Japan Orthopaedic Association (JOA) back pain evaluation questionnaire was significantly higher in group A than in group B (P < 0.05). The navigation system can provide crucial help in the treatment of spinal operation as an assisted method, which has great potential to improve the accuracy and safety. © 2015, E-Century Publishing Corporation.

AIM: To report the results of phacotrabeculectomy with 2.8mm scleral tunnel incision. METHODS: Phacotrabeculectomy was performed through an identical 2. 8mm scleral tunnel incision in 52 eyes of 49 patients with cataract and glaucoma. The incision was closed with out suture. Foldable intraocular lens was implanted in all eyes. RESULTS: The control of intraocular pressure on 36 eyes was desirable. The average postoperative intraocular pressure was (8.24 ± 3.61)mmHg, (13.22 ± 4.12) mmHg, (12.11 ± 4. 23) mmHg and (12.59 ± 4.26) mmHg at one week, one month, three months and six months. As compared with 56 eyes in which phacotrabeculectomy was performed with 5.5mm scleral tunnel sutureless incision, there was no statistical difference, between the two, regarding the mean postoperative intraocular pressure at six months (f=1.7536, P=0.08239). The retinal nerve fiber layer thickness was not statistically different between the preoperative and postoperative times in one year in 26 eyes. The uncorrected postoperative visual activity was 0.8 or better in 62% of 52 eyes. CONCLUSION: The advantages of this operative method are minimal size scleral flap, smaller and sutureless incision, immediate chamber restoration, decrease in postoperative astigmatism, enhanced postoperative visual activity, reduced postoperative inflammatory response and complications.
