扩大的椎板间开窗治疗腰椎间盘突出伴侧隐窝狭窄（附140例报告）

本组采用的扩大的椎板开窗术治疗腰椎间盘突出合并侧隐窝狭窄140例。结果全部优良，与适应症严格选择和手术损伤小有关。强调切除卡压神经根的侧隐窝后壁外侧，即上关节突的冠状面．不失其脊椎三柱系统的三角结构。俯卧位头低足高，可减少硬膜囊张力避免负损伤。切除棘突下椎板时，用神经拉勾代替神经剥离器易于分离黄韧带，用90度的椎板咬骨钳斜向棘突方向，可满意地切除该部份椎板黄韧带，并可刮切椎板内层。神经根周围滴入醋酸炎舒松A2-3ml，术后疼痛锐减。减压窗口置盖明胶海绵有其争议，作者实践体会放置害处不大，要求病人有“护腰”意识。     

Symptomatic liver cyst: Special reference to surgical management

We conducted a retrospective study of 14 patients with symptomatic liver cysts to evaluate current therapeutic interventions for this condition. Abdominal pain (n = 7) or abdominal mass (n = 5) were the most frequent presentations. Three patients also had renal cyst. Percutaneous aspiration with ethanol sclerotheraphy was carried out in 4 patients and all cysts so treated diminished in size, with relief of the symptoms. One patient was treated by aspiration only and re-retension occurred. Cystectomy was performed in 2 patients, unroofing in 5, and fenestration in 2 patients. All patients gained relief of symptoms, with no recurrence of symptoms. Computed tomography revealed that the cysts were diminished or were no longer observable after all the treatments. Our experience indicates that unroofing, fenestration, and cystectomy are safe and suitable procedures for treatment of the condition. Ethanol sclerotherapy may be a feasible alternative to surgical intervention in selected patients. Received for publication on July 23, 1997; accepted on Dec. 25, 1997     

Treatment of labial fenestration of maxillary central incisor

Abstract A case of external inflammatory root resorption and labial fenestration in a maxillary central incisor is presented. The root canal was dressed with pure calcium hydroxide mixed with normal saline for 1 month before it was obturated with gutta percha and apicoectomy surgery undertaken to attempt primary closure of the fenestration. The PDL and the fenestration healed uneventfully.     

地塞米松对扩张皮瓣血运障碍的救治

目的寻求扩张皮肤Ⅱ期手术形成皮瓣时出现血运障碍及防止坏死的有效治疗方法。方法皮瓣出现血运障碍时，立即静脉给予地塞米松0．4mg／kg，然后逐渐减量，术后6d停药。10d时观察判断皮瓣成活情况。结果35例出现血运障碍的皮瓣，经救治完全成活33例，大部分成活2例。成活后皮瓣色泽、弹性均好。结论及时用地塞米松是防止扩张皮瓣出现血运障碍及坏死的良好方法。     

局部手法按摩用于扩张皮瓣的初步探讨

目的总结局部手法按摩用于扩张皮瓣的初步经验。方法自2006年至2007年，我们将手法按摩用于扩张器置入预扩张皮瓣患者21例（35个扩张器）。采用预定的按摩手法，对置入扩张器的皮瓣进行适当按摩。结果本组21例患者，1例因感染取出扩张器，余20例效果满意。与以往未经手法按摩扩张器置入术比较，注水速度明显增快，扩张周期明显缩短。结论局部手法按摩用于扩张皮瓣，安全可靠，效果明显，值得推广。     

Evaluation of Percutaneous Transforaminal Endoscopic Discectomy in the Treatment of Lumbar Disc Herniation: A Retrospective Study

ObjectiveThe objective of the present study was to evaluate the safety and efficacy of percutaneous transforaminal endoscopic discectomy (PTED) and open fenestration discectomy (OFD) in the treatment of lumbar disc herniation (LDH).MethodsPatients in our hospital with LDH who received PTED (n = 71) and OFD (n = 39) from 2013 to 2014 were retrospectively studied. Patient information, including age, gender, visual analogue scale (VAS) score for low back pain and leg pain, body weight, height, Oswestry disability index (ODI), Japanese Orthopedic Association (JOA), and recurrence, was collected. The patients in the two groups were followed up for an average of 63 months after surgery.ResultsA total of 136 patients completed the operation and 110 patients were followed up completely. There was no significant difference in baseline data between the two groups (P > 0.05). The postoperative low back pain, leg pain, ODI, and JOA of the two groups were better than those preoperatively (P < 0.05). One week after surgery, the recovery of PTED patients was better than that of OFD. The ODI score of the PTED group was lower than that of the OFD group (10 [8, 12] vs 14 [11, 16]; P < 0.05), the waist VAS score of the PTED group was lower than that of the OFD group (2 [2, 3] vs 3 [2, 4]; P < 0.05), the leg VAS score of the PTED group was lower than that of the OFD group (1 [0,1] vs 1 [1, 2]; P < 0.05), while the JOA score of the PTED group was higher than that of OFD group [19(16, 20) vs 12(10, 17); P < 0.05]. There were no significant differences in ODI, JOA, waist and leg VAS scores between the two groups at 1 month after surgery and at subsequent follow‐up (P > 0.05). At the end of the follow up, 89.7% (35/39) of patients in the OFD group had excellent improvement in the JOA score, and 88.7% (63/71) of patients in the PTED group had an excellent improvement. There was no significant difference between the two (P > 0.05). There was also no significant difference in the recurrence rate between the two groups [(5/71) vs (3/39); P > 0.05]. [Correction added on 05 March 2021, after first online publication: “3/29” was amended to “3/39” in the preceding sentence.]ConclusionBoth PTED and OFD can achieve good mid‐term efficacy in the treatment of LDH but PTED has certain advantages, including the small incision, a shorter hospital stay, and quicker, earlier recovery. However, prospective randomized controlled studies with a larger sample size are needed.     

退变性腰椎管狭窄症手术治疗的探讨

目的：探讨退变性腰椎管狭窄症的手术治疗。方法：对９４例６０岁以上患者进行分型和手术治疗。结果：将本病分为Ⅰ型（侧隐窝狭窄型）;Ⅱ型（中央管狭窄型）;Ⅲ型（混合型）。对Ⅰ型手术方式采用单侧或双侧椎板开窗,扩大神经根管或（和）摘除髓核;对Ⅱ型行半椎板或全椎板切除术;对Ⅲ型行全椎板切除术。结论：通过术后疗效观察和３年随访,根据分型的不同选择不同的手术方式,可达到较好的临床疗效     

Mastoid size and otitis media with effusion: Question of correlation

Objectives/Hypothesis: To determine the incidence of otitis media (OME) with effusion on histologic examination in temporal bones with mastoid cavities reduced by the fenestration procedure for otosclerosis. Study Design: Temporal bone histologic study. Methods: Light-microscopic examination of serially sectioned temporal bones. Results: The incidence of otitis media with effusion in temporal bones with prior fenestration operation was not any more frequent than the control group of temporal bones with surgically unaltered mastoid cavity. Conclusions: There is no increased incidence of otitis media with effusion in temporal bones with prior fenestration operation.
