The ILMA (Intavent Orthofix Ltd.,Wokingham, UK) has been designed for either blind or fibrescope-guided tracheal intubation, in patients with expected and unexpected difficult airway. Since its development in 1997, it has been used for both blind and fibrescope-guided tracheal intubations in the patients with difficult airway. The ILMA is currently a 'gold standard' in supraglottic airways used for tracheal intubation.
