Sir, I read with great interest the letter Managing aspiration (BDJ 2012; 212: 464). I would like to highlight a few more devices that can be used for preventing aspiration of foreign bodies. A new device, Isolite, delivers continuous throat protection, illumination, retraction and isolation (isolitesystems.com). It has a unique mouthpiece which will prevent aspiration of any foreign objects and also retracts and protects the soft tissues from accidental damage from high speed turbines. A similar device, Isodry, is also available which performs the same function, but requires external lighting.
