| 1 | Quantitative assessment of sensory functions after 3 surgical approaches for trigeminal neuralgia by current perception threshold measurement显示文摘Objective: To quantitatively identify and grade trigeminal sensory functions after 3 major surgical procedures of trigeminal neuralgia using a newly developed quantitative sensory testing technique, current perception threshold measurement (CPTM). Methods: In the current study, there were 48 trigeminal neuralgia patients without history of prior surgical treatment. These patients received one of the following 3 surgical procedures, microvascular decompression (MVD), peripheral nerve block with alcohol (PNB), or percutaneous radiofrequency thermocoagulation (PRFT). The quantitative sensory testing measurement, CPTM, and conventional qualitative sensory testing measurements were performed preoperatively and postoperatively to evaluate and grade the trigeminal sensory functions. All 3 major cutaneous sensory fiber types, large myelinated fibers (A beta), small myelinated fibers (A delta) and unmyelinated fibers(C) were allowed to quantitatively evaluate and grade by CPTM. The results of the measurements were statistically analyzed using a one-way analysis of variance (single factor). Each subject was his/her own control for comparison of the preoperative to postoperative state on the asymptomatic and symptomatic sides. Subjects were tested 48 h preoperatively and 4 weeks postoperatively. Results: PNB with alcohol and PRFT caused significant sensory dysfunction postoperatively in every fiber type, indicating damage to all fibers. On the contrary, the sensory function in all 3 fiber types was unchanged after MVD management. Conclusion: Among the 3 major surgical procedures tested, only MVD preserves sensory function in trigeminal system. CPTM is of quantitative nature on the evaluation of sensory functions of nerve | Chen Ruoping Ouyang Huoniu Wang Bingyu Ding Meixiu Charles J.

| 2 | Application of osteoinductive calcium phosphate ceramics in children’s endoscopic neurosurgery:report of five cases显示文摘This work aimed at investigating the possibility and effectiveness of osteoinductive calcium phosphate(CaP)ceramics to close the drilled skull holes and prevent the postoperative cerebrospinal fluid(CSF)leaking in children’s endoscopic neurosurgery.Five children patients(four boys and one girl,3-to 8-years old)underwent the surgery,in which the endoscopic third ventriculostomy(ETV)was operated in four cases of hydrocephalus,and biopsy and ETV were both performed in one case of pineal tumor.The drilled skull holes were filled with the commercial osteoinductive CaP ceramics.The patients were followed up by CT scan at 1,7 days,3 and 6 months postoperatively.All the five cases were successful,and the holes were closed well after filled with the ceramics.The follow-up survey showed that no CSF leaking or rejection reaction was found.The CT scan indicated that the drilled holes began healing at 7 days postoperatively,and a relatively complete healing happened at 6 months postoperatively.The excellent ability of the CaP ceramics to induce bone regeneration was also confirmed by repairing the skull defects in a monkey model.The results of μ-CT and histological analysis showed that a bony structure with irregular array occurred at the defect area,and the newly formed bone volume density reached 65.7%.In conclusion,the osteoinductive CaP ceramics could be an ideal material to treat the drilled skull holes in children’s endoscopic neurosurgery and prevent CSF leaking afterwards.However,further investigation with more cases and longer follow-up was required to evaluate the clinical effect. | Jia Wei Hufei Qian Yu Liu Jiangang Liu Rui Zhao Xiao Yang Xiangdong Zhu Ruoping Chen Xingdong Zhang | 2018 | Regenerative Biomaterials2018，5，4： | 0 |
