Gliederung

Text

Objective: Tumours of the upper clivus and large paranasal tumours extending to the anterior skull base with penetration of the dura are difficult to approach both with regard to the extent of tumour resection and procedure-related morbidity. Therefore, surgical approaches should enhance exposure of the lesion and at the same time assist in precise localization of the tumour and adjacent structures. Here, we report on a series of patients operated on by craniofacial approaches guided by computer assisted surgery (CAS) techniques.

Methods: Twelve patients were included in this open label study. The surgical approach consisted of a lateral rhinotomy combined with a subfrontal craniotomy if necessary. The procedures were planned and assisted by advanced CAS techniques with image fusion of CT and MRI. Tumors included chordomas, esthesioneuroblastomas and carcinomas.

Results: Combined approaches with CAS proved to be safe and reliable both for identification of tumour borders and vital structures hidden or encased by the tumours. There was no mortality, and the rate of perioperative complications was low including local infection in one patient. There were no new permanent neurological deficits. Tumours were either removed completely, or subtotal resection was achieved allowing targeted postoperative radiotherapy.

Conclusions: Craniofacial approaches enhanced by CAS in a multidisciplinary setting allow safe resection of large tumours of the upper clivus and the paranasal sinuses involving the anterior skull base.
