Jaw Reconstruction With Printed Titanium and Free Tissue Transfer

Inclusion Criteria: * Age over 18 years * Able to provide informed consent * A planned fibular free-flap reconstruction of the mandible * Planned post operative surveillance CT scan 6 months following surgery Exclusion Criteria: * Clinically unfit or inappropriate (based upon prognosis/life expectancy) for reconstruction using free tissue transfer techniques * Patients with planned surgical defects involving formal reconstruction of the condyle. (Clinical use of printed plates for condylar reconstructions would in effect be 'off-licence' and non-standard treatment which is beyond the remit of an observational research study). * Flap failure within the study follow-up period, as this would require early removal of the flap and therefore preclude collection of follow-up outcome data. However, any flap failures (and associated clinical complications/events) will be recorded and reported.
