Objective To evaluate the advantages of nasal septum deviation with three lines reduce tension septorhinoplasty under endoscopy.Methods Three lines reduce tension septorhinoplasty of 48 cases were compared with nasal septum submucous resection(Killian) of 43 cases.Results Followed-up for 3 months to 1 year postoperation,study group were remedied and no clinical symptoms,no complications,control group had septal perforation of 1 case,nasal synechia of 2 cases,saddle nose of 1 case.The incidence of two groups postoperative complications had statistically significant difference.Conclusion Compared with Killian,three lines reduce tension septorhinoplasty was easy to stuty and have the advantages of micro-invasion,safety and efficiency,and was favorable recovery nasal cavitysinuses physiological functions.

Objective To study the techniques for treating the intracranial tumor.Methods Through a keyhole approach with endoscope-assisted micro-neurosurgery,30 patients with intracranial tumor were treated.With microneurosurgery,larger part of tumor was resected,then under neuroendo-scope remains of tumors were found out and removed.Results Tumors were totally removed in 22 patients,subtotally removed in 5.In three patients cerebral aneurysm was clipped successfully.Two patients with pituitary adenoma had temporay diuresis and one patient non-bacteria meningitis,and after two weeks treatment all recovered.There was no-mortality in 41 patients,no cerebral hemorrhage,optic nerve injury,internal carotid injury,and other complications occurred.Conclusion Endoscope-assisted microneurosurgery through a keyhole approach can increase the total-resection rate for tumors,reduce the trauma of operation and postoperative reaction.

Objective To summarize experience of the combined treatment of ependymoma in fourth ventricle of the brain of child and to study improvement of effect of the operation plus radiotherapy.Methods 35 cases with ependymoma in fourth cerebral ventricle were treated with microneuro-surgical resection.Among the 35 cases,25 were treated with total brain and spinal cord plus local focus radiotherapy within 2 to 3 weeks after operation;8 only with local focus radiotherapy,2 cases were not done with radiotherapy.Results Total removal of tumors was done in 20 cases,subtotal removal in 15 cases,and no patient died from operation.After operation,20 patients had a good recovery,10 had a light disability,and 5 needed assistance.The 5-year survival rate were 90.0%(18/20),6.6%(1/15),88.0(22/25),62.5%(5/8) and 0%,in different group respectively.Conclusion Surgical treatment is obviously effective to ependymoma in fourth ventricle of the brain and total removal of tumors combined with radiotherapy is aid to extend the patient's survival time.
