By type, the endotracheal tubes segment accounted for the largest share of the infraglottic airway management devices market
Based on type, infraglottic airway management devices are further segmented into endotracheal tubes and tracheostomy tubes.

Infraglottic airway management devices are expected to be the most widely used type in airway management devices market
Supraglottic devices such as laryngeal mask airway and equipment suitable for emergency infraglottic
access will persist to play an important role in difficult airway situations and should be readily available.
The patient was then admitted to the hospital, and urgent computed tomography (CT) scan of the neck was done and revealed a 3 cm linear foreign body embedded in the soft tissue medial to the left thyroid cartilage with surrounding hypodense soft tissue swelling causing mild indentation of the left vocal cord extending into the supraglottic region up to the left pyriform sinus and downwards minimally extending to the infraglottic
region causing mild asymmetric narrowing of the involved laryngeal segments and causing mass effect on the glottis and supraglottic airway causing mild asymmetric narrowing (Figure 1).
Insertion of the Endotracheal tube through the vocal cords and inflation of the cuff in the infraglottic
region is regarded to contribute very little stimulation.

Vagus and Glossopharyngeal nerves carry the afferent stimulus from epiglottis and infraglottic
region and activate the vasomotor centre to cause a peripheral sympathetic adrenal response to release adrenaline and noradrenaline.
It produces lower hemodynamic instability during placement and avoids stimulating the infraglottic structures.
Hence use of a supraglottic device is justified and there is less stimulation of infraglottic structures which itself can lead to increased secretions and bronchospasm.
