- Aim: To determine the safe and secure mode of endotracheal intubation along with surgeon satisfaction to have adequate room and easy access for Oral & Maxillofacial Surgery .

Cormack and Lahane’ scrore were recorded at laryngoscopy for analysis 1,2,18 . Registered Percentage of Glottis Opening (POGO ) was also evaluated along with the Intubation Difficulty Score (ID S) from 0 to 10. Results: Mallampati classification (1,17) class, i, ii, iii, and iv, was applied to all patients, the percentage found in maxillofacial surgery patients was 0,10,60,30 percent in respective class .After general anesthesia and muscle relaxation with suxamethonium, laryngoscopy done, Cormack and lahane grade 1,9,18 i, ii, iii, iv was 5,20,50,25 percent respectively. Percentage of glottis opening (POGO ) was 40 percent 30 percent 2 0 percent and 10 percent in corresponding Mallampati class . Intubation difficulty score (IDS) from 0 to 10 scale was recorded. The mean was found to be 7.5. Conclusion: There is high degree of airway difficulties 3 and complications of endotracheal intubation associated with maxillofacial surgery which require high level of competence, skills and experience of anesthesiologist to deal with.
