3D soft tissue segmentation for guided botulinum toxin injection in lateral pterygoid muscle

The botulinum toxin administration into the lateral pterygoid muscle has shown promising outcomes in anterior disc displacement with reduction. The deep location of the muscle and its proximity to vital structures and interindividual variation necessitate the use of guidance techniques. This technical report describes a new guidance technique which provides lateral pterygoid muscle segmentation using CT with soft tissue window for 3D augmented environment of the muscle together with its surrounding skeletal and dental structures.
