A computer-assisted optimization approach for orthognathic surgery planning

Computer Assisted Planning in Cranio-Maxillofacial Surgery

In cranio-maxillofacial surgery physicians are often faced with the reconstruction of massively destroyed or radically resected tissue structures caused by trauma or tumours. Also corrections of dislocated bone fragments up to the complete modeling of facial regions in cases of complex congenital malformations are common tasks of plastic and reconstructive surgeons. With regard to the individua...

Integrated planning for blood platelet production: a robust optimization approach

Perishability of blood products as well as uncertainty in demand amounts complicate the management of blood supply for blood centers. This paper addresses a mixed-integer linear programming model for blood platelets production planning while integrating the processes of blood collection as well as production/testing, inventory control and distribution. Whole blood-derived production methods for...

Models for Planning and Simulation in Computer Assisted Orthognatic Surgery

Two aspects required to establish a planning in orthognatic surgery are addressed in this paper. First, a 3D cephalometric analysis, which is clinically essential for the therapeutic decision. Then, an original method to build a biomechanical model of patient face soft tissue, which provides evaluation of the aesthetic outcomes of an intervention. Both points are developed within a clinical app...

Computer Assisted Surgery Planning for Neck Dissections AUTHORS

INTRODUCTION To support the preoperative planning of neck dissections, 3d visualizations are intended to explore and to quantify anatomic and pathologic structures. Neck dissections are carried out for patients with malignant tumors in the head and neck region. These surgical procedures are necessary because the majority of the patients develop lymph node metastases in the neck region. The exte...
