Intraoperative verification of resection margins of maxillary malignancies by cone-beam computed tomography

Resection of maxillary cancer often results in incomplete excision because of the tumour's proximity to important structures such as the orbit. To deal with this problem we prospectively investigated the feasibility of intraoperative imaging during maxillectomy to verify the planned resection margins. In total, six patients diagnosed with maxillary cancer listed for maxillectomy were included, irrespective of the histological type of tumour. Before resection, an accurate intended resection volume was delineated on diagnostic images.
