RESUMO
We describe the use of three-dimensional printing to create precise airway models for a patient with Treacher Collins syndrome who presented for bimaxillary temporomandibular joint prostheses, and for whom airway management was predicted to be difficult. The model was based on pre-operative cone beam computed tomography images and printed in the 3D Lab of Hospital Universitario La Paz. Transparent models allowed clear visualisation for simulation and iterative refinement of airway management techniques and aided in risk assessment and instrument sizing. This case report emphasises the utility of this approach in complex airway scenarios.
RESUMO
Surgical navigation is a technique that has evolved greatly in recent years. It allows surgeons to navigate through the surgical field in real time, and helps to locate anatomical structures or lesions and to place devices in complex anatomical regions with relatively high accuracy. In this article, we describe the application of surgical navigation in temporomandibular joint (TMJ) arthroscopy using an optical surgical navigator for a more precise diagnosis and to accurately place instruments in the desired position, especially in lateral pterygoid myotomy. We believe this technique will extend our understanding of the TMJ anatomy and will improve functional results in TMJ arthroscopy.
