New techniques such as single cord irradiation have been offered for sparing critical perilaryngeal
tumor-free structures (14, 16).
The I-gel (Intersurgical Ltd, Wokingham, Berkshire, UK) is a supraglottic airway device with an anatomically designed non-inflatable mask that snugly fts onto the perilaryngeal
It is designed to create a non-inflatable, anatomic seal of the pharyngeal, laryngeal and perilaryngeal
structures and avoid compression trauma.
Discomfort experienced by patients, sometimes even tenderness and pain within the perilaryngeal
structures prevent the production of voice.
Unexpected death in a horse with arytenoid chondritis and perilaryngeal
This would place it in the category of a cuffed perilaryngeal
sealer like the cLMA (8).
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).
The new perilaryngeal
airway (CobraPLA) is as efficient as the laryngeal mask airway (LMA) but provides better airway sealing pressures.
 However, the cuff needs to be inflated to create a seal around the perilaryngeal
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).
The I-Gel is designed to create a non-inflatable anatomical seal of the pharyngeal, laryngeal and perilaryngeal
structures while avoiding compression trauma.
