Evaluation of the Accuracy of Virtual Planning in Orthognathic Surgery: A Morphometric Study.

Background: The purpose of this study was to prospectively test the accuracy of computer-aided orthognathic surgery comparing the virtual surgical planning with the three-dimensional (3D) outcome.

Methods: Patients that underwent computer-assisted orthognathic surgery were retrospectively evaluated. The postoperative results were compared with the surgical plan, superimposing the postoperative computed tomography (CT) scan onto the virtual plan.

Impact of reconstructive microsurgery on patients with cancer of the head and neck: a prospective study of quality of life, particularly in older patients.

Treatment of cancer of the head and neck often requires extended resection and major reconstructive surgery, both of which can have great functional and emotional impact. It is fundamental to evaluate the outcome with respect not only to the clinical aspects but also to the quality of life (QoL) perceived by the patients. In the light of the reported increasing incidence of oral cancer in older patients, we decided to see if there was an association between QoL and age.
