Computer Vision-Based Recognition of Parathyroid Glands and Recurrent Laryngeal Nerves in Endoscopic Surgery

Starting soon

Conditions studied: Thyroid Diseases, Thyroid Neoplasms

In brief

This study aims to evaluate the performance of the PTAIR computer vision model for recognizing parathyroid glands and recurrent laryngeal nerves during endoscopic thyroid surgery. Multicenter intraoperative endoscopic surgery videos will be prospectively collected. Using the video recorder timeline as the unified time reference, the first recognition time of parathyroid glands and recurrent laryngeal nerves by PTAIR, junior physicians, and senior physicians will be recorded during surgery. The continuous recognition time of parathyroid glands and recurrent laryngeal nerves by PTAIR will also be recorded. This study focuses on the recognition performance of PTAIR in real-world multicenter endoscopic thyroid surgery settings. At this stage, PTAIR will not be used to guide intraoperative surgical decision-making, and the study will not evaluate the effect of PTAIR on clinical outcomes. The collected video data will be used to assess the performance of PTAIR under different centers, surgeons, equipment conditions, and surgical field conditions, and may provide data support for future model optimization.

Who can join

Age: any. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age 18 years or older.
• Patients with benign or malignant thyroid disease who are scheduled to undergo endoscopic thyroid surgery.
• Standardized recorder-based intraoperative video collection is planned during surgery.
• Patients agree to intraoperative video recording, de-identification, and research use.
• Basic perioperative clinical data are available.
• The participating center is able to follow the standardized procedures for video collection, data upload, data security, and annotation quality control.

You may not qualify if…

• Refusal to provide informed consent.
• Patients scheduled to undergo conventional open thyroid surgery.
• Standardized recorder-based intraoperative video collection cannot be performed.
• Intraoperative video quality is insufficient for model analysis or expert review.
• Key surgical phases are missing from the video recording.
• Expert annotation or review of the parathyroid glands or recurrent laryngeal nerves cannot be completed.
• Video de-identification fails.
• Severe missing perioperative clinical data.
• Other conditions judged by the investigators to be unsuitable for study inclusion.
