RESUMEN
The diagnosis of carpal tunnel syndrome (CTS) is mainly based on the characteristic symptoms and confirmed with nerve conduction studies. Sonography can provide measurements of the increased cross-sectional area of median nerve. The use of sonography was evaluated for the diagnosis and postoperative follow up of 48 wrists in 26 consecutive patients with CTS. Clinical evaluation and sonography were effective for the diagnosis in 40 wrists. Nerve conduction studies were needed in eight wrists, because of the decrease in cross-sectional area of the nerve as a result of degenerative changes. After 3 months, sonography detected statistically significant decreases in the cross-sectional areas of the median nerves. The sonographic studies were well tolerated by all patients. Sonography was both time-saving and cost-effective.

This retrospective study included eight consecutive cases with C2 vertebral body neoplastic lesions. The anterior retropharyngeal approach was used to remove the lesions and decompress the spinal cord. Spinal stabilization with occipitocervical plating in a second-stage operation makes the treatment more tolerable for patients. The object of this study was to determine the effectiveness of a two-stage operation strategy for these lesions. Eight patients were operated on via anterior retropharyngeal approach and then stabilized with occipitocervical plates posteriorly in a second sitting. All neck pain and all dysphagia problems resolved. Partial neurologic improvement was achieved in three out of four patients. No postoperative infection was seen. The retropharyngeal approach to the upper cervical spine and anterior foramen magnum lesions is an effective alternative to transoral surgery because of low complication rates. Neoplastic lesions in the upper cervical spine can safely and effectively be operated with this technique. The general medical status of patients with malignancies does not permit too long, time-consuming operations. Stabilization of the spine in a separate operation increases patient tolerability without any morbidity.
