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(More)
OBJECT Fractures of the odontoid process are the most common fractures of the cervical spine in patients over the age of 70 years. The incidence of fracture nonunion in this population has been estimated to be 20-fold greater than that in patients under the age of 50 years if surgical stabilization is not used. Anterior and posterior approaches have both(More)
OBJECT The most contentious issue in the management of os odontoideum surrounds the decision to attempt atlantoaxial fusion in patients with asymptomatic lesions. The authors examined the clinical presentation and outcome in patients with os odontoideum who underwent surgical stabilization, with an emphasis on 3 patients who initially received conservative(More)
Neurenteric cysts are endothelium-lined structures most commonly encountered in the lower cervical or upper thoracic spinal cord. The occurrence of neurenteric cysts within the cranial vault is unusual. We present three patients with neurenteric cysts located within the posterior fossa: one near the jugular foramen deforming the 4th ventricle, a second in(More)
STUDY DESIGN A retrospective review of contemporaneously acquired clinical data supplemented by experimental cadaver dissection. OBJECTIVE To establish the incidence and mechanism of vocal cord paralysis after anterior cervical spine surgery and to determine whether controlling for endotracheal tube (ET)-laryngeal wall interactions induced by the cervical(More)
OBJECTIVE The traditional boundaries of the transsphenoidal approach may be expanded to include the region from the cribriform plate of the anterior cranial base to the inferior clivus in the anteroposterior plane, and laterally to expose the cavernous cranial nerves and the optic canal. We review our combined experience with these variations on the(More)
OBJECT In this, the first of two articles regarding C1-2 transarticular screw fixation, the authors assessed the rate of fusion, surgery-related complications, and lessons learned after C1-2 transarticular screw fixation in an adult patient series. METHODS The authors retrospectively reviewed 191 consecutive patients (107 women and 84 men; mean age 49.7(More)
BACKGROUND CONTEXT Surgery is usually required for treatment of cervical myelopathy to decompress the neural elements, restore lordosis, and stabilize the spine. By addressing these problems, the neurological deterioration may be halted. PURPOSE Multilevel cervical discectomy and fusion offers several advantages over other approaches. The authors describe(More)
OBJECTIVE Vocal fold paralysis is the most common otolaryngological complication after anterior cervical spine surgery (ACSS). However, the frequency and etiology of this injury are not clearly defined. This study was performed to establish the incidence and mechanism of vocal fold paralysis in ACSS and to determine whether controlling for endotracheal(More)
Meningiomas are the most common tumors affecting the cavernous sinus (CS). Despite advances in microsurgery and radiosurgery, treatment of CS meningiomas remains difficult and controversial. As in cases of other meningiomas, the goal of treatment for CS meningioma is long-term growth control and preservation of neural function. Gross-total resection, the(More)
