Chinese Journal of Minimally Invasive Surgery 2001;0(06):-
Objective To discuss the microsurgical treatment for tethered cord syndrome (TCS) caused by intraspinal lipomas. Methods Thirty-two patients with intraspinal lipoma TCS were treated microsurgically. On surgery the tethering lesions of lipoma were excised and anomalies restricting the spinal cord were removed. Results Following the operation, cerebrospinal fluid subcutaneous leakage had occurred in 3 patients, who were cured by expectant treatment. The patients were followed for 3~12 months (mean, 6 months). Five patients were cured, 21 got improved, and 6 had no change. Conclusions Application of microsurgical technique for intraspinal lipoma TCS has advantages of fewer complications and better improvement of nerve functions.

Chinese Journal of Minimally Invasive Surgery 2005;0(07):-
Objective To investigate advantages and disadvantages of unilateral hemilaminectomy for the microsurgical removal of cervical intraspinal tumors. Methods Twenty-three patients with cervical intraspinal tumors were treated microsurgically with unilateral hemilaminectomy. In condition that the vertabral lamina was kept intact in bony structure, an opening (key-hole) was made in the unilateral lamina by using a drill or a small-sized bone rongeur. Then cervical intraspinal tumors were removed via the “key-hole”. Results Tumors were completely removed in all the 23 patients and no symptoms relating nerve injuries were observed. Postoperative follow-up for 3~16 months (mean, 8 months) revealed no recurrence and spinal deformity. Conclusions Unilateral hemilaminectomy for the treatment of cervical intraspinal tumors is a mini-invasive procedure which benefits the spinal stability. The pitfall of the technique lies in limited surgical field.
