[A new implant system in head and neck surgery].

Defects in the head and neck region following extensive tumor removal are sometimes difficult to reconstruct by local or free flaps. An epithesis is a recommended alternative in defects of the ear, the nose or the orbital region. Nevertheless problems may arise in the appropriate fixation of the epithesis. With the intermobile-cylinder-implant-system (IMZ), the epithesis is firmly fixed by means of osseointegration of the implants and an abutment in the area of the defect. The various steps of the operation and clinical applications are presented.
