Performance Status < 2
Patient aged 18 or over
Patient affiliated with social security system
History of squamous cell carcinoma of the VADS or skin of the face.
History of cervico-facial radiotherapy
Primary tumor discovering during pan-endoscopy
Inexposable patient lead not to possible mucosectomy
