Thoracic disk herniation.

Symptomatic thoracic disk herniation is unlikely to be encountered with significant frequency in clinical practice. Subtle manifestations required a high index of suspicion if the work-up is to be efficient. In the appropriate candidate, magnetic resonance imaging is the best screening tool, and it may be the only diagnostic study required. In the symptomatic patient with neurologic dysfunction or persistent pain refractory to nonsurgical therapy, surgical diskectomy is a safe and effective treatment with limited morbidity.

Surgical repair of aneurysms of the posterior inferior cerebellar artery--a clinical series.

Aneurysms of the posterior inferior cerebellar artery are relatively rare. Fourteen such aneurysms (10 vertebral, 4 peripheral) are reported, and their clinical presentation, surgical therapy, and outcome are discussed. All 14 patients had suffered a subarachnoid hemorrhage; 93% (n = 13) underwent direct clipping of the aneurysm while 7% (n = 1) underwent coating of the aneurysm. Two patients died in the perioperative period (one from vasospasm and one from rebleeding). Full activity was achieved by all but one (92%) of the remaining patients in extended follow-up.

Fixation of fractures of the lower cervical spine using methylmethacrylate and wire: technique and results in 99 patients.

Surgical stabilization of traumatic fracture-dislocations of the lower cervical spine with wire and methylmethacrylate remains a controversial procedure. Yet, the resultant immediate fixation with minimal patient morbidity seems to indicate that this method provides an ideal stabilization construct. We describe and report the outcome of a technique of posterior cervical fixation with methylmethacrylate and wire for stabilization of traumatic fractures of the lower cervical spine. Over a 12-year period, 124 fracture-dislocations of the lower cervical spine in 99 patients (mean age, 32 years; range, 15-76 years) were treated at this institution using a posterior methylmethacrylate and wire technique. Eighty-two patients had a posterior element fracture; 28 had a vertebral compression with posterior ligamentous injury; and 14 had a ligamentous injury alone. Thirty-six patients were neurologically intact upon admission, while the rest had radiculopathy or partial or complete myelopathy. Ninety-one patients were available for follow-up [mean, 18.6 months; range, 1-100 months (8.33 years)]. Eighty-eight patients (97%) had a stable fixation and 77 (85%) had resumed preoperative activity or were working but with a residual deficit. Complications included fixation failure requiring a second operation in 3 patients, nonlethal pulmonary embolism in 2 patients, lethal pulmonary embolism in 1 patient, and a superficial wound infection in 3 patients (none affected the underlying fixation construct). These results indicate that this technique is a safe, simple, and effective method for stabilizing the lower cervical spine that allows rapid patient mobility with minimal morbidity.

Transalar sphenoidal encephaloceles: clinical and radiologic findings.

Two cases of occult basal encephalocele protruding through defects in the greater wing of the sphenoid bone are presented. The cases are unique in that they occurred in adults with non-localizing symptoms and were eloquently imaged by computed tomography (CT) and magnetic resonance (MR). While the theoretical existence of this type of encephalocele has been recognized, no documented cases of transalar sphenoidal encephalocele are known to have been reported in the radiology or surgery literature.

Cooperative neuro-otologic management of acoustic neuromas and other cerebellopontine angle tumors.

Over a recent 16-month period, 35 cerebellopontine angle tumors were removed at our institution by a surgical team consisting of one neurosurgeon and one otologist. Nineteen tumors were less than 2 cm in diameter and six were greater than 4 cm. There were 26 acoustic neuromas, six meningiomas, two epidermoid tumors, and a glossopharyngeal schwannoma. A suboccipital transmeatal approach was used in the majority of patients. There were no deaths. Thirty-two patients had an excellent outcome. Twenty-four patients had complete tumor removal (92% of the acoustic neuromas). The facial nerve was preserved anatomically in all but one patient, who had nerve grafting intraoperatively and has partial recovery of function. Thirteen of the 24 patients who had auditory function retained some of it postoperatively. With current diagnostic techniques, combined with the neurosurgical and otologic team approach, the majority of patients with acoustic tumors of all sizes may expect a complete resection of the tumor with a good outcome. Certainly, early diagnosis and resection of smaller tumors will increase the likelihood that hearing will be preserved, thus providing impetus for aggressive diagnostic and surgical treatment of patients with these lesions.
