A difficult airway
is a situation where an anaesthetist finds difficulty in mask ventilation, tracheal intubation or both (ASA 2003).
The risks of using anAEC for management of a difficult airway
include dislodgement of the tube, airway trauma (e.g., endobronchial rupture (11) and lung laceration (12)), cough, laryngospasm, failed reintubation, hypercapnia or hypoxemia, aspiration, and barotrauma.

The management of any difficult airway

In this issue of CMJ, Wang et al . reported their findings from a multicentric prospective randomized study which had tested a new approach, fast difficult airway
evaluation (FDAE), for difficult facemask ventilation after anesthetic induction.
GAGs accumulations in the mucosa and soft tissues of the upper respiratory tract cause enlargement of the larynx, tonsils, adenoids, and tongue, leading to a difficult airway
or obstruction during general anesthesia [16,17].
Despite various studies being conducted on prediction of difficult airway
, not many studies have been conducted as multivariate analysis of readily available variable like ratio of height to thyromental distance to be compared with other parameters for assessment of airway like upper lip bite test (ULBT), modified Mallampati test (MMT), inter incisor Gap (IIG) and thyromental distance (TMD).
Thyroidectomy for huge MNG with compromised airway is usually associated with difficult airway
management at the time of induction of anesthesia, during and after surgery6,7.
Failure to report a difficult airway
can contribute to severe complications during subsequent anaesthesia and represents a failure in professional duty (4).

emergency intubations easier.
