Optical diagnostic techniques in the head and neck.
The aim of this review article is to compare findings from recent prospective studies on microendoscopy, fluorescence spectroscopy (FS) and elastic scattering spectroscopy (ESS) with histopathology on formalin-fixed surgical specimens, to assess if those techniques can be used as an adjunct or alternative to histopathology in defining tissue involvement.


CONCLUSIONS
These are non-invasive techniques to aid diagnosis, treatment and follow-up, used to guide the more acurate delivery of treatment, eg photodynamic therapy specifically to abnormal areas.
