[Imaging of the post-irradiation larynx for laryngeal and hypopharyngeal carcinomas].

Imaging has a key role in the follow-up of patients treated for laryngeal or hypopharyngeal carcinoma. Imaging is complementary to clinical evaluation and has three goals: evaluation of chemo and radiation therapy; differentiation between complications and tumour recurrence; early detection of tumour recurrence, prior to clinical manifestations. Imaging may allow early detection of recurrences, when salvage treatment may still be less radical.
