How does ear ministry tumour check?

First: otoscopy: most patients have tympanic membrane perforation, through the perforation can be seen in the middle ear cavity red granulation, easy to touch bleeding. When the tumor destroys the bony external auditory canal, granulation tissue can also be seen in the ear canal, red, soft and brittle, easy to bleed.

Second, CT, MRI and other imaging and pathological examinations of skull base and temporal bone should be carried out in time when bleeding or bloody secretions are found in the ear. Pathological examination after middle ear cavity granulation or external ear canal granulation removal can make a definite diagnosis. CT findings of otitis media with destruction of bone wall of external auditory canal and formation of soft tissue mass of external auditory canal should be highly suspected of middle ear cancer.

Third: subtotal temporal bone resection: the scope of resection includes external auditory canal, mastoid process, part of temporomandibular joint, squama of temporal bone, and 1 / 2-1 / 3 outside petrous bone. Only part of internal auditory canal, part of internal carotid artery and petrous apex in internal carotid artery are reserved.

matters needing attention

Because the middle ear tumor is wrapped by temporal bone, radiotherapy is difficult to completely cure, so surgery plus radiotherapy can significantly improve the curative effect. If the tumor invaded the carotid artery and could not be removed, radiotherapy should be considered first to reduce the tumor area, and then surgery should be performed.
