 Welcome to the Touch Surgery interactive app on Maxillary Sinus Anatomy and Maxillary Sinus Augmentation. I'm Mike Newman. I'm a professor emeritus at UCLA, and I'm the Dentistry Advisor to Touch Surgery. Our current Maxillary Sinus simulation covers the anatomy of this area in depth. Clinicians, students, and residents will be able to review the key points of the Maxillary Sinus Anatomy step by step, and then you'll be able to test yourself and verify your understanding of this critically important area. With the inclusion of real clinical data, you'll be able to apply what you've seen in the simulation to your own clinical experiences. The simulation has been authored by a group we've had a lot of experience in teaching and learning and who are in the clinics daily. The thorough understanding of the anatomy is critical prior to performing any surgical procedure. Touch surgery is well suited where we are dealing with complex anatomy and delicate structures that are difficult to master from conventional educational resources. When we move into the surgical arena, we don't have any tools that are giving us an opportunity to practice the procedure before we're actually doing it. Touch surgery is able to bring interactive learning in front of our students and residents and support the most complex procedures. Having this Touch surgery module is an invaluable resource, provides an opportunity to learn, to practice, to rehearse. Having this terrific reference and training tool will help provide safe surgery.
