This study proposes to develop a computer-based software tool that will allow surgeons to plan and simulate surgery for patients with jaw trauma.

Clinical Details

Official title: Advanced Visuohaptic Surgical Planning for Trauma Surgery

Study design: Observational Model: Case-Only, Time Perspective: Retrospective

Primary outcome: Development and evaluation of the visuohaptic virtual surgery planning environment

Secondary outcome:

Development and evaluation of automation features for the visuohaptic virtual surgery planning environment

Implementation and test of the telemedicine prototype

Detailed description: The proposed tool will allow surgeons from different specialties to simulate, plan and iterate on complex procedures based on individual patient data in 3-D from a CT scan. The

software will allow surgeons to both see and feel the results of their interventions - for

example, the quality of the bite or bone alignment of a reconstructed jaw following severe

trauma - before the actual surgery, leading to better planning, fewer errors, shortened

surgery time and improved outcomes for the patients. The purpose of this study is the evaluation of a visuohaptic planning system for mandibular trauma surgery that is based on interactive manipulation of CT data.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

- Craniofacial deformity, including post-traumatic, congenital or acquired deformity

- Patients who have already have surgery because there was a clinical indication for

surgical correction Exclusion Criteria:
