Background: Digitally designed surgical templates for minimally invasive temporomandibular joint (TMJ) surgery (MITMJS) are a promising tool for improving the safety in these procedures. Given the anatomy of the TMJ, the fitting of the template and intraoperative overview are the most important issues to conduct the surgery safely. This article describes an endaural surgical template based on the Moses approach as a possible solution.Material and Methods: Three patients with internal

None of the patients needed an additional open surgical procedure. Fitting of the templates was judged in terms of position and rotational stability. Surgical side effects and complications were recorded for each patient.Results: The template design and clinical use performed the MITMJS satisfactory. The templates showed satisfying fit and good visibility. In the study cohort, no bleeding, facial nerve injury, or other complications occurred after the procedure, and no visible scars were noted postoperatively.Conclusion: Our feasibility report on template-guided MITMJS shows a promising new application of templates. It points an improved access in arthroscopy or arthrocentesis of TMJ- surgery via an endaural access with increased level of safety during surgery.
