“…It was noted, however, that the anterior approach needed a more in-depth dissection of structures to obtain an identical range. In recent years, renewed interest has gained by many surgeons with regard to the posterior approach to treat cervical spine lesions, because of advancements in minimally invasive surgery and endoscopy, with a series of reports detailing excellent treatment outcomes 1,2,9-11, [15][16][17][18] . In cases where foraminotomy or discectomy is performed via the posterior approach (using microscopy, endoscopy, or both), it is necessary for the bones to be removed once the lateral mass at the site of the lesion is secured and for the muscles to be dissected to a minimal extent, using a narrow retractor.…”

“…Great advances have been made with the posterior approach with the development of equipment such as the microscope and the endoscope. Advantages of the posterior approach include an ability to avoid damage to vital structures located in the anterior area of the cervical spine (i.e., the trachea, esophagus, internal carotid artery, vertebral artery, thoracic duct, and recurrent laryngeal nerve), an ability to prevent structural and biomechanical damage to the remaining vertebral disc by preserving it, an ability to lower the morbidity associated with the joint, and an ability to reduce the occurrence of complications associated with the bone graft, as well as degenerative changes at the adjacent joint 2,[9][10][11]16,18) . In cases where only dorsal decompression of the nerve root is performed and only fragments of the intervertebral disc are removed, excellent treatment outcomes have also been reported 7,8,12,20) .…”

Objective : Morphometric data on dorsal cervical anatomy were examined in an effort to protect the nerve root near the lateral mass during posterior foraminotomy. Methods : Using 25 adult formalin-fixed cadaveric cervical spines, measurements were taken at the lateral mass from C3 to C7 via a total laminectomy and a medial one-half facetectomy. The morphometric relationship between the nerve roots and structures of the lateral mass was investigated. Results from both genders were compared. Results : Following the total laminectomy, from C3 to C7, the mean of the vertical distance from the medial point of the facet (MPF) of the lateral mass to the axilla of the root origin was 3.2-4.7 mm. The whole length of the exposed root had a mean of 4.2-5.8 mm. Following a medial onehalf facetectomy, from C3 to C7, the mean of the vertical distance to the axilla of the root origin was 2.1-3.4 mm, based on the MPF. Mean vertical distances from the MPF to the medial point of the root that crossed the inferior margin of the intervertebral disc were 1.2-2.7 mm. The mean distance of the exposed root was 8.2-9.0 mm, and the mean angle between the dura and the nerve root was significantly different between males and females, at 53.4-68.4°. Conclusion : These data will aid in reducing root injuries during posterior cervical foraminotomy.

“…This approach has been previously described by Saringer [5] for decompressive foraminotomies in the subaxial spine, by Wolinsky [6] for treatment of basilar invagination and recently in a large series of patients by Yao [7] for discectomy and interbody fusion (ACDF).…”

Purpose The Authors illustrate the feasibility of an open biopsy and complete excision of Osteoid Osteoma involving the C2 vertebral body performed via endoscopic anterior cervical approach. Methods A 23-year-old male patient with history of delayed diagnosis of cervical Osteoid Osteoma underwent evaluation and surgical treatment: the minimally invasive procedure and techniques were described. The clinical features, the radiological findings and the outcome were assessed. Complications and local recurrences were also recorded. Results There were no intra-or post-operative complications. Immediately after surgery the typical Osteoid Osteoma related pain disappeared. At three years follow-up the patient was asymptomatic and considered disease-free: CT-scan and x-Ray showed no local recurrence and C2-C3 interbody fusion with cervical plate in site. Conclusions The endoscopic transcervical surgery represents an interesting option for the treatment of these diseases in difficult areas of the upper cervical spine, also minimizing soft tissue trauma and collateral damage allows patients a faster and complete return to normal function. To our knowledge this is the first report of cervical spine tumor removal using this minimally invasive approach.

“…84 Saringer, et al, 84 used the microendoscopic discectomy system in conjunction with a modification of Jho's 42 technique of resection of the uncovertebral joint to allow for anterior endoscopic cervical nerve root decompression. Advantages of this technique include a very small surgical exposure, improved intraoperative visualization, direct decompression and visualization of the nerve root, and avoidance of graft-related complications/preservation of the motion segment (a bone graft is not required).…”

Neuroendoscopy has grown rapidly in the last 20 years as a therapeutic modality for treating a variety of spinal disorders. Spinal endoscopy has been widely used to treat patients with cervical, thoracic, and lumbosacral disorders safely and effectively. Although it is most commonly used with minimally invasive lumbar spine surgery, endoscopy has gained widespread acceptance for the treatment of thoracic disc herniations and for anterior release and rod implantation in the correction of thoracic spinal deformity. The authors review the use of endoscopy in spine surgery and in the treatment of spinal disorders as well as in the treatment of intrathoracic nonspinal lesions. Endoscopy has some significant advantages over open or other minimally invasive techniques in that it can allow for better visualization of the lesion, smaller incision sizes with reduced morbidity and mortality, reduced hospital stays, and ultimately lower cost. In addition, spinal endoscopy allows observers and operating room staff to be more involved in each case and fosters education. Spinal endoscopy, like any novel modality, carries with it additional risks and the surgeon must always be prepared to convert to an open procedure. The learning curve for spinal endoscopy is steep and the procedure should not be attempted alone by a novice surgeon. Nevertheless, with training and experience, the spine surgeon can achieve better outcomes, reduced morbidity, and better cosmesis with spinal endoscopy, and the operating times are comparable to open procedures. As technology evolves and more experience is obtained, neuroendoscopy will likely achieve further roles as a mainstay in spine surgery.
