12 Systems face: computer aided treatment of facial diseases
For human beings the face has an existential meaning. With its
mimic it represents the unique perceivable identity of an
individual. The face is the part of the body where the most important
sense organs are placed on a close area. The facial musculo-skeletal
system consists of the bony morphological fundament and the functional
soft tissues. For any surgical treatment this has to be
considered. The aim of this project is to create a setup for complex
facial surgery. The analysis, the surgical planning and the simulation
should be based on a 3D universal model of the human face.
12/1 Facial surgery
Development of a reference data set representing the statistical
variability of face and head appearances within the population. The
statistical model on the appearance of faces will be used to develop
novel registration methods for a better quantitative comparison of
A new CO2-laser with a computer-assisted scanner allowing a precise
and arbitrary guidance of the laser beam will be tested to allow new
and sophisticated cut geometries. Navigation systems and robotics will
be tested to extend the surgical possibilities and to improve the
Simulation of highly realistic 3D pictures of the post surgical shape
combining both volume and surface data to build a physically based
facial model, allowing interactive manipulations and the prediction of
resulting facial shape.
Clinical evaluation of the planning, intraoperative and postoperative
changes and prediction of operations in the field of septorhinoplasty,
otoplasty, parotid surgery and extensive tumour surgery.
