- Primary Outcome Measures
Name Time Method To correlate Thyromental height test with ease of direct laryngeal visualization as assessed by Cormack-Lehane grading.. <br/ ><br>Timepoint: Difficulties in visualization of the vocal cords during laryngoscopy and intubation, usually graded as Cormack &Lehane grade III and IV and classified as ââ?¬Å?difficultââ?¬? <br/ ><br>Grade I: Full view of the glottis. <br/ ><br>Grade IIa: Partial view of the glottis is visible. <br/ ><br>Grade IIb:Arytenoids or posterior part of the vocal cords only just visible. <br/ ><br>Grade III: Only epiglottis is visible. <br/ ><br>Grade IV: No glottis structures visible .
- Secondary Outcome Measures
Name Time Method To correlate clinically mallampati grading, sternomental distance, thyromental distance with direct laryngeal visualization as assessed by Cormack Lehane grading. <br/ ><br> 2.To assess time taken for endotracheal intubation. <br/ ><br> 3.To correlate TMHT with the incidence of difficult intubation. <br/ ><br>Timepoint: Difficulties in visualization of the vocal cords during laryngoscopy and intubation, usually graded as Cormack &Lehane grade III and IV and classified as ââ?¬Å?difficultââ?¬? <br/ ><br>Grade I: Full view of the glottis. <br/ ><br>Grade IIa: Partial view of the glottis is visible. <br/ ><br>Grade IIb:Arytenoids or posterior part of the vocal cords only just visible. <br/ ><br>Grade III: Only epiglottis is visible. <br/ ><br>Grade IV: No glottis structures visible .
