for CSM, there is Level III evidence indicating that laminectomy may be associated with late deterioration. Although this may not speak completely against laminectomy as a means of treatment, especially if there are technical issues in utilizing other techniques, it does argue for consideration of other techniques in younger patients in whom late deterioration my be more likely to develop. Key Issues There are several well-accepted surgical techniques for treating CSM. Because of the high relative effectiveness and similarity of costs and complications after

arduous challenge, and the benefit of radiation therapy alone is often limited because of the proximity to the optic nerve. 1 , 18 Some recent series reported on the strategy of resection in conjunction with postoperative radiation. 20 , 22 , 27 , 28 The feasibility of radical resection has been debated. In our opinion, the key to achieving favorable surgical outcome is safe and strategic drilling of the hypertrophied skull base structures. In this study, we describe our surgical technique for SOMs in detail and report the outcome of our series. Methods

surgical technique could facilitate minimally invasive surgery for skull base tumors. Given the relatively rare occurrence of tumors in Meckel’s cave, the clinical efficacy of the exposure provided in these routes is still insufficient to clarify the selection of indications and methods. To our knowledge, this report is the first documentation of the use of this eTOA in a clinical series to provide endoscopic minimal access to middle fossa tumors using the transorbital route. Here, we share our preliminary experiences of a series of 9 patients who underwent endoscopic

Origins of Wilder Penfield's surgical technique

The role of the “Cushing ritual” and influences from the European experience

Mark C. Preul and William Feindel

A s with the earlier generation of pioneer neurosurgeons at the beginning of the 20th century, Wilder Penfield (1891–1976) developed his surgical technique largely on his own initiative. 18 As he had worked out his own education in neurophysiology and neuropathology, so too he organized the development of his surgical technique and the eventual formation of a distinct neurosurgical school. 6, 10, 20 Penfield used Cushing's operative technique as a “sort of classic” and “constantly referred to the general principles which he laid down in neurosurgical

OBJECTIVE

Cervical artificial disc replacement (C-ADR) is a widely used procedure with low risk at implantation. Few cases have been reported about the surgical techniques of C-ADR revision. The authors describe their surgical experience with the explantation of a Galileo C-ADR.

METHODS

Revision surgery was performed in a 58-year-old patient. Patient positioning and surgical opening techniques were performed as appropriate for anterior cervical decompression.

RESULTS

Revision surgery via the initial anterior approach was successful following an atraumatic removal of the implant. Fusion of the C5–6 segment was performed without complications.

CONCLUSIONS

In general, the authors observed recurrent nerve palsy and malpositioning of the revised implant in C-ADR revision surgery. Problems with implant removal did not occur because the fusion rate was low due to the short time between initial surgery and C-ADR revision surgery.

on all patients, in most patients with CM-I and syringomyelia the authors performed a posterior extra-intradural decompression due to data suggesting that patients with syringomyelia have a significantly greater prevalence of arachnoid veils obstructing the foramen of Magendie. 15 , 29 , 43 Surgical Technique Step 1: Posterior Extradural Decompression and Intraoperative Ultrasound Assessment All posterior extra-intradural decompressions for CM-I with or without syringomyelia are performed similarly. Prior to intraoperative assessment by ultrasound, a posterior

pump implantation. Although pump insertion is considered by some to be similar to shunt placement (that is, merely the installation of hardware), there are different nuances to each operation that influence outcome. The ITB Therapy Best Practice Forum was held in Minneapolis, Minnesota, in 2004 to discuss patient selection and screening, surgical technique, and ongoing medical management. Fourteen faculty members representing five medical specialties participated in the conference (Appendix) . Implantation techniques were discussed, and recommendations were

, especially when the tumors become large or giant. These tumors usually compress, displace, or encase vital neurovascular structures in the vicinity of the ACP, such as the optic nerve, the oculomotor nerve, and the ICA and its branches. Peritumoral edema contributes to the difficulty of resecting these deep skull base tumors. An anterior clinoidal meningioma may also extend into the cavernous sinus. The extent of removal is dependent on the surgeon's ability to safely dissect tumor from these critical structures. Several patient series describing surgical techniques and

in the form of a foramen or a notch. The type of passage in each dry skull was evaluated, and the distance from the supraorbital foramen or notch to midline was measured. The nasofrontal suture was considered a useful and simple anatomical landmark during Level I, II, and III craniofacial approaches. The distances between the anterior and posterior ethmoidal foramina and the optic canal were also measured.

S uccessful repair of all abnormal characteristics of unicoronal plagiocephaly remains a challenge for craniofacial surgeons. Although the phenotypical characteristics of unicoronal plagiocephaly have been clearly described (ipsilateral supraorbital rim elevation [vertical dystopia] and retrusion, ipsilateral frontal bone retrusion, ipsilateral temporal constriction, contralateral frontal boss, contralateral temporal boss, and C-shaped deformity of the face), current surgical techniques often do not successfully achieve long-term correction of all of the
