About this study
Official title: Evaluation of the Correlation Between Body Roundness Index (BRI), Body Mass Index (BMI), and VIDAC Score in Obese Patients: A Prospective Observational Study
The VIDIAC score is a measurement system that objectively defines glottic visibility and anatomical complexity in videolaryngoscopy. The literature has shown a relationship between parameters such as BMI, NC, and TMD and difficult airway management in obese patients, but there is no study examining the BRI-VIDIAC relationship.
Read the detailed description
Obesity is a clinical condition that alters the anatomical airway structure and can increase intubation difficulties.
Body Mass Index (BMI) alone is not a sufficient predictor of airway management; it is important in conjunction with measurements such as obesity-related fat distribution, neck circumference, and temporomandibular joint dysfunction (TMD). Body Roundness Index (BRI) is a new anthropometric indicator that reflects body fat distribution more accurately than BMI.

The literature has shown a relationship between parameters such as BMI, NC, and TMD and difficult airway management in obese patients, but there is no study examining the BRI-VIDIAC relationship.
This study aimed to examine the correlation of BRI and BMI values with the VIDIAC score and to determine whether BRI is a stronger predictor of difficult airway management than BMI.
