3D 4K Exo-Endoscopic Temporal Bone Dissection: A Novel Approach for Sharing the Anatomy.

Area of Science:

• Otolaryngology
• Surgical Anatomy
• Medical Education Technology

Background:

• Temporal bone dissection is a key training method for otologic surgeons.
• Understanding infratemporal facial nerve anatomy is critical for surgical practice.
• The 3D exoscope is a novel tool recently introduced in ear surgery.

Purpose of the Study:

• To evaluate the utility of a 3D exoscope for temporal bone dissection.
• To study the anatomy of the infratemporal facial nerve using 3D exoscope technology.
• To assess the educational benefits of 3D exoscope-assisted temporal bone dissection.

Main Methods:

• Two temporal bone dissections were performed using a high-definition 3D exoscope (3D VITOM®) and a VERSACRANE™ holding system.
• A 3D endoscope (TIPCAM®1 S 3D ORL) was used in conjunction for enhanced visualization.
• The focus was on studying the infratemporal facial nerve anatomy and fine anatomical relationships.

Main Results:

• The 3D exoscope provided high-quality visualization during temporal bone dissection.
• The technology facilitated shared surgical field viewing for trainees.
• High interchangeability was observed between the 3D exoscope and the 3D endoscope.

Conclusions:

• 3D 4K exo-endoscopic temporal bone dissection offers significant educational advantages, particularly for anatomy comprehension.
• The 3D exoscope shows promise as a valuable tool for otologic surgical training.
• Further cohort studies are recommended to investigate the teaching superiority of this technology.
