Download Parotid tumour requiring mastoid tip removal

R Theo Gregor
Clinical appearance
Right sided parotid tumour in young woman, present for few years
CT Scan
Axial view showing mass deep to the superficial lobe on the right; appears to be a deep
lobe tumour, but not a true parapharyngeal extension. Position of the facial nerve is not
seen . See arrows showing the lateral extent of the tumour.
CT
Coronal view. Lesion is seen between superficial lobe and the great vessels medially. See
arrows
CT
Coronal view showing the mastoid process. Note how closely the tumour is applied.
Surgery
Shows the flaps raised. Note the great auricular nerve passing upwards across SCM muscle
Surgery
Tumour can be seen deep to the raised superficial lobe closely applied to the mastoid
process. See red arrows
Surgery
The mastoid tip is drilled away in order to expose the facial nerve, which is deep to the
mass. The main trunk was found to be elongated by the mass, and entirely deep to it.
Closure
The incision is hidden in hair line, and the superior portion is hidden behind the tragus,
because this is young patient, with no obvious skin creases.
