 We pathologically examined invasive pathways of metastatic nasopharyngeal carcinoma to the temporal bone structure,by using temporal bone serial sections of 4 patients.

 Histopathology of these patients revealed that the main pathway was invasion from the petrous apex to middle ear and mastoid cavity,and the carcinoma proceed to the internal auditory canal and cochlear in more advanced cases. Meanwhile the alternative pathway was invasion along Eustachian tube. The progressive speed of the alternative pathway was slower than that of the main pathway.
