Abstract

Background: Increasing the use of tobacco by the younger generation has increased in oral cavity tumours. Surgical treatment is radical and results in severe functional morbidity. Using computer-aided designing technology, surgical and rehabilitative planning can be better. We present here our concept of a biomechanical 3D tongue model and its clinical utility in the management of tongue tumours. Methods: Patients diagnosed with Carcinoma of Tongue were included. These patients underwent a pre-operative Magnetic Resonance Imaging (MRI) of the head and neck region at our center. These patients were informed about the use of a 3D biomechanical patient-specific model for treatment planning and execution. Using Materialise Mimics Innovation Suite 19 DICOM data was imported, visualized, edited and segmented. Flashforge ‘Creator-pro’3D Printer was used for 3D Printing. Fused Deposition Modeling (FDM) technology was used to print the tumour and uninvolved tongue in two different colors for easy identification. These patients underwent surgery with the 3D model serving as a guide for margins. Results: Two patients with stage III squamous cell carcinoma of tongue underwent the surgery based on the plan evolved from the 3D model. All the surgical margins were clear. The model helped address the discordance between patient expectations and surgical outcomes. We found that the model aided the reconstructive surgeon to plan the flap volume better and this translated into better rehabilitative outcomes. Discussion and Conclusion: The 3D biomechanical tongue model is a novel concept and may aid in improving our overall treatment outcomes.
