Computer Vision-Based Recognition of Parathyroid Glands and Recurrent Laryngeal Nerves in Endoscopic Surgery (PTAIR)
Prospective Multicenter Model Validation Study of the PTAIR Computer Vision Model for Recognition of Parathyroid Glands and Recurrent Laryngeal Nerves During Endoscopic Thyroid Surgery
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.

Descrição detalhada
Identification of the parathyroid glands and recurrent laryngeal nerves is an important component of safe thyroid surgery. Parathyroid glands are small and may resemble surrounding fat, lymph nodes, or soft tissue. The recurrent laryngeal nerve has a complex anatomical course and may be partially covered by fascia or insufficiently exposed in some cases, which may increase the difficulty of intraoperative recognition. Computer vision-based artificial intelligence models may help recognize these structures in endoscopic surgical images, but their performance in multicenter real-world surgical settings requires further validation.
Previous PTAIR studies mainly focused on parathyroid gland recognition in endoscopic thyroid surgery videos. Based on these prior studies, the present study will further evaluate the PTAIR model in a prospective multicenter setting, with a focus on recognition of parathyroid glands and recurrent laryngeal nerves. This stage of the study is designed as a model performance validation study and will not evaluate whether PTAIR changes intraoperative surgical decisions, parathyroid management, or postoperative clinical outcomes.
During endoscopic thyroid surgery, PTAIR, junior physicians, and senior physicians will identify parathyroid glands and recurrent laryngeal nerves based on the same intraoperative endoscopic visual field. All time-related outcomes will use the video recorder timeline as the unified reference. The study will record the first recognition time of the recurrent laryngeal nerve and parathyroid gland by PTAIR, junior physicians, and senior physicians, as well as the continuous recognition time of these structures by PTAIR. Expert-reviewed annotations will be used as the reference for subsequent model performance evaluation and confirmation of recognition results.
The study will also evaluate PTAIR performance under different exposure conditions, including cases with fascial coverage, incomplete exposure, or complex surgical field conditions. Multicenter video data will be used to assess model performance across different centers, surgeons, equipment settings, and operative field conditions, and may provide data for future model improvement and iteration.

Multicenter Endoscopic Thyroid Surgery Video Cohort
This cohort includes adult patients with thyroid disease who are scheduled to undergo endoscopic thyroid surgery and consent to intraoperative video recording and research use.
Recorder-based intraoperative videos will be collected to evaluate the recognition performance of PTAIR for parathyroid glands and recurrent laryngeal nerves.
The recognition results of PTAIR will be compared with those of junior and senior physicians based on the same intraoperative endoscopic visual field and the same video recording timeline.
|
PTAIR is a computer vision model used to recognize parathyroid glands and recurrent laryngeal nerves in endoscopic thyroid surgery videos.
In this observational study, PTAIR will be used to analyze recorder-based intraoperative videos and evaluate first recognition time, continuous recognition time, and recognition performance.
PTAIR results will be compared with recognition by junior and senior physicians based on the same intraoperative endoscopic visual field and the same video recording timeline.
At this stage, PTAIR will not be used to guide intraoperative surgical decision-making.
