Towards a three-dimensional software model of the oral cavity for tongue surgery planning
Abstract
This work introduces the contribution of a biomechanical model of the oral cavity in the planning of tongue resection surgeries. For this, we exploit a 3D biomechanical model of the tongue (finite element modelling), in which major tongue muscles, either extrinsic or extrinsic, are represented implemented. This model is inserted in the oral cavity including jaw, palate, pharyngeal walls, as well as the hyoid bone. Two common tongue excisions with reconstruction are modelled: a hemiglossectomy and an enlarged mouth floor resection. The impact of the flap mechanical properties on tongue mobility and the production of vowels \i, a, u\ are evaluated in theabsence of any compensatory strategy.
