The LMA and similar supraglottic airway devices use an inflatable cuff to wedge into the upper oesophagus and provide a perilaryngeal
A specific feature of the design of PLMA is the presence of a second cuff on the mask backplate, connected to the main perilaryngeal
cuff and aimed to increase oropharyngeal sealing by pushing the PLMA against the larynx from the posterior hypopharyngeal wall (Figure 1).

This would place it in the category of a cuffed perilaryngeal
sealer like the cLMA (8).
4] However, the cuff needs to be inflated to create a seal around the perilaryngeal
The new perilaryngeal
airway (CobraPLA) is as efficient as the laryngeal mask airway (LMA) but provides better airway sealing pressures.
The I-Gel is designed to create a non-inflatable anatomical seal of the pharyngeal, laryngeal and perilaryngeal
structures while avoiding compression trauma.
I read with interest the recent article of Andrews and colleagues, comparing the Classic-LMA[TM] (LMA) to the Cobra Perilaryngeal
Airway[TM] (PLA) (1).
I-GEL is anatomically preformed to mirror the perilaryngeal
Hence the design of our study was aimed to compare current real world LMA use (including size selection) with the Cobra Perilaryngeal
Airway[TM] and we believe that our results reflect this practice.
It is designed to achieve a mirror impression of pharyngeal and laryngeal structures and to provide a perilaryngeal
seal without cuff inflation.
