Abstract
As science and technology advances, many tests such as modified mallampatti test (MMT), Ratio of Patient’s neck circumference to thyromental distance (NC/TMD) and upper lip bite test (ULBT) were introduced to predict difficult intubations. The study is aiming at to find out the different predicting value of difficult laryngoscopy. To compare the predictive value of modified mallampatti test (MMT), ratio of patient’s Neck circumference to thyromental distance (NC/TM) and upper lip bite test (ULBT) as methods of airway assessment for difficult laryngoscopy performed in patients undergoing surgeries under general anaesthesia in Tripura Medical College and Dr. BRAM Teaching Hospital. A comparative study has been conducted among 225 participants (75 each study group) in TMC and BRAM Hospital during 2022‐23 aged between 18‐65 years who are under general anaesthesia. All data were collected in a proforma and compared with Cormack‐lehane scale. Data were entered and analyzed using SPSS 21.0 and expressed in descriptive statistics. Chi‐square test for categorical variables and t test and ANOVA were applied for quantitative data. A p value of <0.05 were considered significant. Total 225 patients were participated in the study with the mean age was 40±13 years where male: Female is 1:1. Difficult intubation was seen more by MMT: 17.3% than UBLT: 20%. The ULBT shown good specific (93.74%) than other two test respectively (81.34%: MMT and 67.89%: NC/TMD). The significance AUC was also observed in ULBT and NC/TMD than MMT (p‐value 0.02 and 0.001). The ULBT is better predictor for difficult intubation than MMT and NC/TMD directing further study with higher sample in multi‐centric mode.
