Surgery of acoustic neuromas. Preliminary experience with a translabyrinthine approach.

Inspired by the works of William House, the authors formed an otoneurosurgical team in order to improve the results after surgery for acoustic neuromas. This paper deals with the preliminary results obtained with the translabyrinthine approach in 13 patients with acoustic neuromas. In 9 patients it was possible to remove the tumor totally with this approach, in 4 patients a second suboccipital operation was necessary to secure total removal. One small, 7 medium and 5 large tumors were encountered. The facial nerve was preserved in 83 per cent of the patients. One patient with a large tumor died after the second suboccipital operation. The relation between size of the tumor and the outcome of the operation is stressed, and in order to reduce the number of large tumors it is suggested that all patients with unilateral hearing loss should be suspected of having a neuroma, until the diagnosis has been disproved. It is concluded that the surgery for acoustic neuromas is otologic-neurosurgical teamwork, and that the treatment should be centralized.

The late neurological, psychological, and social aspects of severe traumatic coma.

Thirty patients who had survived a heavy head trauma and a post-traumatic coma, lasting for more than one week, were investigated 8 to 14 years after the trauma. The patients have been followed up from a social, psychological, and neurological point of view. Fifty per cent of these patients are considered to be well rehabilitated. All the investigated patients showed slight to severe reduction in mental capacity. Eighty per cent of the patients had neurological defects which were not as important with respect to social rehabilitation as was the mental capacity reduction.
