Abstract

The soft palate is essential in speech, yet understanding of soft palate muscle function remains coarse. Traditional descriptions have focused almost exclusively on the extrinsic portions of soft palate muscles such as levator veli palatini (LVP) and palatoglossus (PG). However, the limited observations available in the literature suggest that the intrinsic portions are essential in primary soft palate functions, i.e., the reshaping of the palate needed to constrict the velopharyngeal port (VPP) and the oropharyngeal isthmus (OPI). We present simulations using a 3D biomechanical model of the soft palate with the goal of clarifying the distinct roles that the intrinsic and extrinsic portions of these muscles play in VPP and OPI control.
