Motion analysis for objective evaluation of psychomotor skills in Endoscopic Sinus Surgery.

Background: This study aims to digitalize surgical maneuvers in ESS using a motion capture system under standardized conditions provided by 3D printed-sinus models.

Methodology: Forty-seven otolaryngologists performed ESS on 3D printed models manufactured from computed tomography (CT) images of actual patients. Participants were classified to 3 groups according to the objective structured technical skills assessment score.

Surgical skill analysis focused on tissue traction in laparoscopic wet lab training.

Background: Tissue handling is one of the pivotal parts of surgical procedures. We aimed to elucidate the characteristics of experts' left-hand during laparoscopic tissue dissection.

Methods: Participants performed tissue dissection around the porcine aorta.

An open-globe injury case caused by brown bear attack.

Purpose: To document a case of open-globe injury (OGI) caused by a brown bear attack that resulted in a favorable structural and visual outcome.

Observations: A 40-year-old Japanese female was transported by ambulance due to OGI with a choroidal hemorrhage in the right eye, resulting in light perception (LP) visual acuity following a brown bear attack. We pursued a two-stage approach, commencing with primary posterior scleral wound repair and an encircling scleral buckle.

Validation and motion analyses of laparoscopic radical nephrectomy with Thiel-embalmed cadavers.

Purpose: Our aim was to develop practical training for laparoscopic surgery using Thielembalmed cadavers. Furthermore, in order to verbalize experts' motion characteristics and provide objective feedback to trainees, we initiated motion capture analyses of multiple surgical instruments simultaneously during the cadaveric trainings. In the present study, we report our preliminary results.
