The goal of this study is to compare between the blind technique and US guided technique in insertion of the LMA and confirming its position. A 102 patients who underwent elective surgery were randomly selected and grouped into 2 groups, 51 in each group. Group B: using the blind technique in positioning of the LMA and confirming its position by the fiberoptic score and group U: using the US in positioning the LMA and confirming its position by the fiberoptic score The laryngeal mask insertion time for 1st group was significantly shorter than that for the 2nd group. The fiberoptic glottic view scores for 2nd group was significantly better than that for the ones for 1st group. The side effects and complications had no statistical difference between the two groups.
