Posterior Decompression

Odontoid pseudotumor is a mass occurring around the odontoid process in the cervical spine and can cause significant neurological symptoms at the craniocervical junction due to compression of the spinal cord and cervicomedullary junction at this level. A literature review was performed to provide input on options for treatment and prognosis for this lesion. The literature search found 12 papers in which pseudotumor was treated with posterior decompression and fixation. Posterior decompression and fixation with serial imaging to monitor the size of the pseudotumor postsurgery is a safe and effective treatment option for odontoid pseudotumors.

Instabilities of the craniocervical junction can be of rheumatic, traumatic, or congenital origin. The reported patient has a congenital malformation of the cervical spine, which is frequently observed in patients with Klippel–Feil syndrome. Her posterior arch of the atlas (C1) is hypoplastic and a chronic subluxation of the atlanto-axial joint would be possible. Although most common fusions in Klippel–Feil syndrome patients exist at C2/3, the majority of studies about Klippel–Feil syndrome deal with pediatric or adolescent individuals. Through extreme flexion of her neck, there was a compression of the spinal cord by the odontoid process. This led to a quadriplegia lasting about 10 min. Over the following weeks, all of her symptoms started to diminish. This situation turned out to be the third episode involving temporary neurological disorders in this 60-year-old female’s life.

Abstract For the past 20 years, the transoral approach to the upper cervical spine has been utilized for odontoid fractures, the removal of an abnormal odontoid process, decompression of basilar impression, and biopsy or resection of nasopharyngeal or metastatic tumors. The effectiveness and safety of this procedure is well documented. Use of the surgical microscope adds to the efficiency and safety of the procedure. We are reporting a case of fusion of the odontoid base to the anterior arch of the atlas. To our knowledge, this entity has not been described previously. The spinal cord was protected by an initial posterior fusion of C-1, C-2, followed in 10 days by a tracheostomy and the transoral removal of the anterior C-1 arch and the abnormal dens. Because the medical history did not reveal a source of trauma, it is supposed that the patient had malunion of the odontoid process to C-2, with subsequent migration and fusion of the dens to the C-1 arch.

One Step

Type I Chiari malformation is often accompanied by congenital developmental abnormalities such as platybasia, basilar impression and C2 odontoid process retroflexion that may cause anterior compression of brainstem structures and upper cervical segments of spinal cord. Formerly the conventional method was posterior decompression even in presence of anterior brainstem compression. This article presents on a kinetic example the tactics of one-step treatment of patients with type I Chiari malformation accompanied by basilar impression and C2 odontoid process retroflexion via transoral approach only that was used for both decompression and C1-C2 segment anterior stabilization. Surgical intervention enabled to achieve the decompression of brainstem structures and upper cervical segments of spinal cord, normalization liquor dynamics and subsequent redislocation of cerebellar tonsils to normal position (above the Chamberlain line).

Transdural Approach

The transoral transpharyngeal approach is the standard approach to resect the odontoid process and decompress the cervicomedullary spinal cord. There are some significant risks associated with this approach, however, including infection, CSF leak, prolonged intubation or tracheostomy, need for nasogastric tube feeding, extended hospitalization, and possible effects of phonation. Other ventral approaches, such as transmandibular and circumglossal, endoscopic transcervical, and endoscopic transnasal, are also viable alternatives but are technically challenging or may still traverse the nasopharyngeal cavity. Far-lateral and posterior extradural approaches to the craniocervical junction require extensive soft-tissue dissection. Recently, a posterior transdural approach was used to resect retro-odontoid cysts in 3 adult patients. The authors present the case of a 12-year-old girl with Down syndrome and significant spinal cord compression due to basilar invagination and a retro-flexed odontoid process. A posterior transdural odontoidectomy prior to occiptocervical fusion was performed. At 12 months after surgery, the authors report satisfactory clinical and radiographic outcomes with this approach.

Canal Stenosis

Rheumatoid arthritis (RA) is an inflammatory autoimmune disease that impacts on weakening ligaments, synovial arthritis and cartilage damage. The effect that can occur is instability and neural compression in the upper and sub-axial cervical. The prevalence of atlantoaxial instability (AAI) is around 40-80% among rheumatoid patients, but it is interesting to examine the clinical symptoms that are not so visible despite radiological instability confirmed on the cervical spine. However, once the clinical symptoms of myelopathy occur, the mortality rate will increase sharply. We report a case of a 66-years old female who was admitted to our hospital with gait disturbance and weakness of her lower extremities. Radiographic evaluation of the cervical spine showed erosive destruction of the odontoid process of C2, anterior atlantoaxial subluxation, and thickened yellow ligaments from C3 to C7. Surgery was performed by removal of the posterior arch of C1 and laminectomy C3 to C7, posterior occipito-cervical screw fixation from C3 to C7, combined with atlantoaxial transpedicular screw fixation. A sterno sub-occipitomandibular immobilization (SOMI) orthosis was applied for postoperative immobilization for 12 weeks. Improvement of motoric status noted after surgery.

Neurocysticercosis, is the most common central nervous system parasitic infestation worldwide, but spinal involvement by neurocysticercosis is relatively rare. Here we report a case of 18-year-old male patient with intramedullary cysticercosis caused by Tenia soleum in cervical spinal cord. MRI revealed expansile illdefined intramedullary mass at C4 and C5 vertebral level which believed to be a tumor instead, rather than a cysticercosis preoperatively. surgery was performed to decompress the spinal cord. Histopathological examination of removed lesion confirmed it as cysticercosis.

✓Cordectomy is an effective treatment option in patients in whom posttraumatic syringomyelia develops following complete spinal cord injuries. Since the introduction of cordectomy, numerous approaches to the surgical treatment of posttraumatic syringomyelia have been developed. These newer developments have drawn the attention of surgeons and researchers away from cordectomy. In this report, the authors encourage a reconsideration of cordectomy for the treatment of posttraumatic syringomyelia after complete spinal cord injury. They describe four patients with posttraumatic syringomyelia who were treated successfully with cordectomy and review appropriate literature, examining the effectiveness of cordectomy in the treatment of posttraumatic syringomyelia. The findings of this review indicate that neurological improvement or stabilization occurred in 88% of patients in published reports of posttraumatic syringomyelia treated with cordectomy. The indications for cordectomy as well as factors that may contribute to the procedure’s success are discussed.
