Efficacy of Image-Guided Percutaneous Endoscopic Ear Surgery: A Novel Augmented Reality-Assisted Minimally Invasive Surgery.

Abstract

Objective: Although transcanal endoscopic ear surgery (TEES) offers benefits of minimal invasion, it is difficult to access certain regions of the temporal bone, often necessitating a switch to more invasive methods, such as mastoidectomy. To overcome these challenges, we developed "image-guided percutaneous endoscopic ear surgery (IGPEES)," a novel technique designed to enhance the precision and safety of ear operations by integrating augmented reality (AR) and advanced navigation systems, allowing precise, minimally invasive access to the mastoid antrum and other difficult-to-reach areas. This study aimed to evaluate the efficacy and safety of IGPEES through a retrospective analysis of 11 cases.

Study design: Retrospective analysis.

Setting: Tertiary referral center.

Main outcome measures: We analyzed the setup time and accuracy for navigation and complication rates of IGPEES.

Results: Our results demonstrated that IGPEES reduced setup time and enhanced navigation accuracy compared with conventional surgical navigation systems, with no postoperative complications observed, thereby representing a promising advancement in otologic surgery.

Conclusion: The integration of AR into IGPEES facilitates better surgical visualization and precision, potentially transforming standard practices for treating complex ear conditions.
