Summary
This study developed a nomogram to predict poor operative visibility during functional endoscopic sinus surgery (FESS). The tool accurately identifies high-risk patients, aiding preoperative planning and perioperative management for chronic rhinosinusitis.
Area of Science:
- Otolaryngology
- Surgical Oncology
- Medical Informatics
Background:
- Chronic rhinosinusitis (CRS) management often involves functional endoscopic sinus surgery (FESS).
- Poor operative visibility during FESS can complicate procedures and affect outcomes.
- Predictive tools for intraoperative conditions are crucial for surgical planning.
Purpose of the Study:
- To develop and validate a predictive nomogram for poor operative visibility during FESS.
- To identify key risk factors associated with poor surgical field in FESS patients.
Main Methods:
- Retrospective analysis of 369 CRS patients undergoing FESS.
- Utilized LASSO and multivariate logistic regression to identify risk factors.
- Developed and evaluated a nomogram using training and verification datasets with ROC analysis, calibration curves, and decision curve analysis.
Main Results:
- Identified six risk factors: prothrombin time (PT), prothrombin activity (PTA), Lund-Mackay score (LMS), Lund-Kennedy score (LKS), anesthetic method, and intraoperative hypertension.
- The nomogram achieved an AUC of 0.820 (training set) and 0.852 (verification set).
- Demonstrated good calibration, clinical usefulness, and net benefit.
Conclusions:
- The developed nomogram effectively predicts poor intraoperative visibility in FESS for CRS patients.
- This tool aids in preoperative risk assessment and informs perioperative management strategies.
- Enhances surgical planning and potentially improves patient outcomes in FESS.
