Summary
Older age, longer disease duration, multiple maneuvers, anxiety, diabetes, and hypertension are key factors influencing residual symptoms after benign paroxysmal positional vertigo treatment. A predictive model aids in assessing outcomes.
Area of Science:
- Otolaryngology
- Neurology
- Internal Medicine
Background:
- Benign paroxysmal positional vertigo (BPPV) can lead to residual symptoms post-treatment.
- Identifying factors influencing these residual symptoms is crucial for patient management.
Purpose of the Study:
- To identify independent risk factors for residual symptoms after BPPV treatment.
- To develop a predictive nomogram model for treatment outcomes.
Main Methods:
- Retrospective analysis of 186 BPPV patients treated between June 2019 and August 2021.
- Logistic regression analysis to determine independent risk factors.
- Construction and validation of a nomogram model using R software.
Main Results:
- Residual symptoms were observed in 44.09% of patients.
- Independent risk factors identified: age, disease duration, number of maneuvers, anxiety, diabetes mellitus, and hypertension.
- The nomogram model demonstrated high predictive accuracy (AUC = 0.938) with good calibration.
Conclusions:
- A nomogram incorporating age, disease duration, number of maneuvers, anxiety, diabetes, and hypertension effectively predicts residual symptoms in BPPV patients.
- This model can aid clinicians in anticipating and managing treatment outcomes.
