Diagnostic Techniques for Evaluation of the Paranasal Sinuses

Physical examination of the paranasal sinuses is often insufficient to confidently reach a conclusion concerning suspected pathology in these cavities.

These techniques can be used to diagnosis and determine the cause of most sinus disorders.
