Background: Paraglossal technique was described as early as 1930 but is seldom taught now or practiced.
Objective: To evaluate the effectiveness of paraglossal technique over conventional approach and to evaluate the ease of insertion and glottic view obtained.
Type of the study: Randomized Controlled Trial
Material and methods: After taking informed consent 140 patients scheduled for elective surgery under general anesthesia were enrolled for the study. They were randomally divided into Group P: Intubation was performed using paraglossal approach with Miller blade and Group C: Intubation was done using conventional larynogoscopy technique with Mcintosh blade. Comparisons were made in improvement in Cormack Lehane grade, intubation difficulty score, time taken for intubation and complications if any.
Results: Cormack Lehane Grade I was obtained in 97.1% ( 68) subjects in paraglossal group as compared to 67.1% ( 47) in group C (p=0.02). Time taken for intubation was significantly more in group C (p=0.014). The median (IQR) IDS value were 4 (4-5) and 5 (4-6) paraglossal and conventional laryngoscopy respectively. The Median (IQR) ease of intubation on Likert scale was graded as 1 (1-2) and 1 (1-1) for Group P and C respectively.
Conclusion: Paraglossal approach improves the glottic visualization and also leads to successful intubation. We recommend that paraglossal approach be taught to anesthesia residents as an alternative technique so that it can be used with confidence if conventional laryngoscopy fails.
