RECONSTRUCTION IN MAXILLO-FACIAL AREA

The purpose of this work was to develop a method for a safe and optimal resection of
tumor in the maxillo-facial area and post-resection bone reconstruction. To optimize
these procedures it is crucial to design the surgical scenario on virtual models based on
individual medical images and implement the designed scenario intraoperatively under
control of computer navigation.
The paper describes the newly developed system for virtual planning of tumor resection
and designing the geometry of bioimplant which is provided to reconstruct the loss of
bone. The system applies both CT and MRI data. The developed system possibly will
enable optimization of surgical procedure, since the designed surgical scenario can be
followed intraoperatively under simultaneous control of optical and electromagnetic
navigation.
2. INTRODUCTION
The procedure of cancer resection demands high precision regarding safety of vital
structures such as blood vessels and nerves [1]. Moreover to reconstruct bone after bone
loss involved by tumor resection it is crucial to define the geometry of implant or bone
graft.
The application of bone allograft causes problems, such as non-efficient vascularization
causing loss of the graft or mismatched autograft to the bone loss after cancer resection.
The surgical procedure using autograft is time consuming, demands additional operation
access, what causes additional pain and higher risk of infection.
