Wrapping a man-made dura around reconstructed nerve sleeve avoid residue or recurrence of sacral Tolav cysts

Abstract Objective To evaluate the therapy effect on patients with sacral extradural meningeal cysts with nerve root fibers by wrapping a man-made dura around reconstructed nerve sleeve. Patients and methods In order to avoid the cysts residue and recurrence postoperative, wrapping a man-made dura around reconstructed nerve sleeve, a new operating method, was performed in 24 patients with 42 cysts. After the nerve sleeve being reconstructed, wrapping and suturing a man-made dura around the nerve sleeve was performed. The Improved Japanese Orthopedic Association (IJOA) scoring system was used to evaluate preoperative and postoperative neurological function. Results Among 24 patients, 14 were females, and 10 males. Three-month after open surgery, no cyst residue or recurrence was grasped in any patient. The mean IJOA score was 18.8 ± 1.32 preoperatively and 19.6 ± 0.65 postoperatively, which was a significant difference between the preoperative and postoperative scores ( t  = −3.82, P  = 0.001). These results indicate a significant improvement in neurological function after surgery. Conclusion Based on reconstruction the nerve sleeve, wrapping with man-made dura and forming double nerve sleeve was safety and effective operating method for treatment the sacral extradural meningeal cysts with nerve root fibers.
