Condylar add-on system

The reconstruction of oromandibular defects following surgical extirpation of oral cavity carcinoma presents a significant surgical challenge. Mandibular deformities and defects may result from trauma, infections, exposure to radiation, neoplasms, and congenital defects; most mandibular deformities arise as a result of ablative surgery for neoplasms. The consequential changes to the oromandibular anatomy caused by a resection of the primary and regional metastases are oftentimes not only functionally disabling but also socially isolating. therefore a complete subsequent recovery of function as well as aesthetics is exceptionally important whenever reconstruction is considered.

The new condylar head add-on system (CAS) provides a temporary solution for reconstruction of the mandibular condyle. To achieve optimal fit in the patients glenoid fossa, the system includes four different fixation plates that adjust the height of the condylar head on the 2.4 mm mandible reconstruction in 2 mm increments. Unlike the already existing 2.4 mm plate with fixed condylar head this new systems height adjustment allows it to be used on a larger number of patients.

This device is not intended for use as a permanent prosthetic device, for patients with temporomandibular joint disorders, or patients with traumatic injuries of the TMJ.
