RESUMO
Four examples are given to demonstrate the problems, methods and advantages of intra-operative sonography for intra-spinal tumours. The value of intra-operative sonography for localising the tumours and for judging their extent is demonstrated and related to other imaging methods, such as myelography, CT and MR.

Twenty-six patients with mostly small intracranial space-occupying lesions were examined sonographically during surgery. In all patients, accurate localisation and complete delineation of the intra-cerebral lesion proved possible. The extent of the lesion could be determined accurately and surrounding cerebral structures were identified unequivocally. There were no significant differences in the appearances before and after opening of the dura. The significant advantage of the intra-operative use of sonography lies in the accurate localisation of the space-occupying lesion. This results in a reduction of interference with normal cerebral tissue and in a reduction of the duration of the operation.

The authors emphasize that the maxillo-facial surgeon or otorhinolaryngologist should: 1. take part in diagnosing and planning the therapy of poly-traumatic patients. 2. operate simultaneously when possible. 3. try to provide immediate maxillo-facial surgical and/or otorhinolaryngologic treatment because of the great importance of early treatment for longterm functional and aesthetic results.
