As an early proof-of-concept study, Dr. Frank-Ito and his team prospectively constructed nasal models from computerized tomography (CT) scans of 10 patients undergoing surgical treatment for NOA (see Figure 1, and Figure 2). The scans were taken prior to surgery, and five and eight months following surgery. To create the transcribed-surgery and post surgery models, the surgeon digitally hand-edited the preoperative scans to represent the physical changes that were expected from the surgery. Steady-state, laminar, and inspiratory inflow were simulated in each model. The results were not as robust as they had hoped, largely related to software limitations (Otolaryngol Head Neck Surg. 2014;151:751-759).
“We hope that, eventually, this will become a way for the surgeon to meld radiologic and other studies into a platform that lets them virtually plan and even practice long before they enter the nose,” said Dr. Frank-Ito. “The pre-surgery platform would allow surgeons to ‘try out’ different procedures virtually before deciding the best procedure to perform on a given patient.” | ← Previous | | | Next → | Single Page
