A Novel Design of Computer-Assisted 3D-Printed TMJ Arthrocentesis Guide (Technical Note)

Abstract

Attempts of needle relocation and extension of the operation time are the most common cause of postoperative edema and swelling after temporomandibular joint arthrocentesis. To facilitate the placement of needles and decrease patient discomfort, a template-based technique that includes design of patient-specific guide was performed to direct access to the temporomandibular joint space for arthrocentesis.
