AbstractThe authors report the results obtained in a series of more than 80 cases submitted to 76 operations of the upper cervical spine by transoral approach with a minimum follow-up of two years. The cases include: 15 unstable fractures or non-union of the odontoid processes; 28 cases of post-traumatic instability of C1-C2 level without fracture of the odontoid process; 13 cases of rheumatoid arthritis with instability at C1-C2; 14 cases of severe anomalies of the craniovertebral junction, often associated with basilar impression and spinal cord compression, of which 7 cases presented with tetraparesis; 6 malignant tumors. The method used involves an anterior transoral approach, more often without tracheotomy, and with exposure of the anterior aspect of the atlas and of the odontoid process by means of a midline incision of the posterior wall of the pharynx. When spinal cord lesion was present, decompression and reconstruction by bone grafts taken from the iliac crest were performed. In nearly all of the cases osteosynthesis with an anterior plate was used. Complications were mild. There were two cases of infection, observed at the onset of our experience, which were resolved after removal of the instrumentation. There was loosening of a screw in three cases; this was eliminated through the digestive tube with no consequences. There were no early intra- or postoperative deaths. Consolidation was obtained in most of the patients, and only in three cases did we observe a loss of postoperative reduction. Among patients affected with tetraparesis we observed many cases of neurological recovery.(ABSTRACT TRUNCATED AT 250 WORDS)
