BACKGROUND: One of the common indications for removal of the odontoid process includes decompression of the cervicomedullary junction in patients with arthritic degeneration. Resection of the odontoid process can be accomplished using a completely transnasal endoscopic approach. METHODS: A retrospective review was performed of patients with rheumatoid pannus undergoing transnasal ...

The endoscopic endonasal approach is emerging as a feasible alternative to the transoral route for the resection of the odontoid process, when the latter produces a compression of the brainstem and cervicomedullary junction. This type of approach has some advantages, such as excellent prevertebral exposure of the craniovertebral junction in ...

The classification of odontoid process fractures introduced by Anderson and D'Alonzo in 1974 has gained wide acceptance among researchers and clinicians. In type II fractures the injury is located in the base of the odontoid process. In 1988 Hadley et al. introduced a comminuted subtype of this fracture, type IIA. ...

A type III fracture of the odontoid process according to Anderson-D'Alonzo in a 92-year-old patient was stabilized anteriorly with two double-threaded screws using the technique of Knöringer. Postoperatively, cranial dislocation of the screws was evident and attempts to correct the screw position failed resulting in screw proximity to the brain ...

A new technique is described for the removal of ligaments and soft tissue during a transoral resection of the odontoid process in a patient with rheumatoid arthritis. The technique employed is Coblation, a form of electrosurgery that operates at lower temperatures than conventional electrosurgical technique and, therefore, produces less collateral ...

We report three patients in whom a fractured odontoid process was associated with a fracture of the superior articular process of the second cervical vertebra. Although there were no signs of neurological disorder, damage to the C1-C2 joint in all three patients made fusion necessary. Forced lateral flexion is suggested ...

A 52-year-old man complaining of headache and nuchal pain was treated initially under a diagnosis of bacterial meningitis. The meningitis resisted antibiotic therapy, and one week later was complicated by a ruptured retropharyngeal abscess, which led to the correct diagnosis of osteomyelitis of the odontoid process of the axis. His ...

The authors describe a unique retraction device adapted for anterior odontoid screw placement. A rigidly fixed tubular retractor system obviates the need for dissecting the longus colli muscles as well as for excessive retraction of the trachea, esophagus, and recurrent laryngeal nerve. The proper trajectory for screw placement can be ...

A number of approaches have been attempted to address the treatment of acute odontoid fractures, spanning from conservative treatment with an external orthotic device to posterior C1-C2 arthrodesis or anterior screw fixation. The current report describes stabilisation of such fractures with a C1 supralaminar hook and a C2 pars interarticularis ...

Pseudotumour of the craniovertebral junction is an uncommon cause of high cervical myelopathy in the elderly. The anterior transoral approach is the preferred means of accessing these lesions. An "odontoid sparing" transoral approach, in which there is only minimal bone removal, is thought to preserve stability of the craniovertebral junction, ...

A total of 150 odontoid fractures was treated over a 12-year period, 43 by anterior screw fixation. The rate of pseudarthrosis dropped from 20% to 5% in type II unstable fractures. Thus, anterior screw fixation seems to be safe and efficient, and may be more widely used to treat all ...

Four different radiological diagnostic methods were compared as to their diagnostic relevance in the analysis of odontoid fractures. Thirty-one patients with fresh odontoid fractures were investigated using standard anteroposterior and lateral radiographs, conventional tomography, axial computerized tomography and two-dimensional reconstruction in the sagittal and the coronal planes. As a control, ...

Eleven patients with documented Morquio's syndrome who had dysplasia of the odontoid process and resulting atlanto-axial instability were reviewed. They were found to be at risk for acute traumatic quadriparesis, chronic myelopathy of a variable and often rapid rate of progression, and sudden death by respiratory arrest. The evidence suggests ...

Resection of the odontoid process and anterior arch of the atlas results in atlantoaxial instability, which if left uncorrected may lead to severe neurological complications. Currently, such atlantoaxial instability is corrected by anterior and/or posterior C1-C2 fusion. However, this results in considerable loss of rotation function of the atlantoaxial complex. ...

A retro-odontoid pseudotumor is usually a reactive fibrocartilaginous mass associated with atlantoaxial subluxation (AAS). However, a retro-odontoid pseudotumor not associated with AAS, which undergoes spontaneous regression following C1 laminoplasty, has been reported. The purpose of this study was to report surgical outcomes of C1 laminectomy for retro-odontoid pseudotumor without AAS. ...

OBJECT: The management of odontoid fractures remains controversial. Only direct anterior screw fixation provides immediate stabilization of the spine and may preserve normal C1-2 motion. To determine the indications, optimum timing, and results for direct anterior screw fixation of odontoid fractures, the authors reviewed the surgery-related outcome of patients who ...

Controversy exists in the literature regarding the adequacy of one or two screws for direct fixation of the odontoid process. Proponents of the two-screw technique believe that a single screw is not adequate to stabilize the fracture. Conversely, the insertion of two 3.5-mm screws in the medullary cavity of the ...

Our experience with 12 patients with metatropic dysplasia has demonstrated two important and treatable complications: odontoid hypoplasia with subluxation of the first and second cervical vertebrae, and ventriculomegaly. Hypoplasia and lack of ossification of the odontoid process were noted in all cases. Subluxation of these two vertebrae was demonstrated in ...

Retro-odontoid synovial cysts are rare and attributable to degenerative changes in the atlantoaxial joints. An anterolateral approach facilitates access to lesions located anterior to the craniocervical junction without harming the atlantoaxial joints, and can also treat small lesions in the ventral mid-portion of the craniocervical junction without compression of spinal ...
