Difficult Airway Society guidelines airway assessment tongue protrusion inability intubation

Inability to protrude the tongue suggests restricted tongue mobility, often from tongue-tie, floor-of-mouth pathology, swelling, infection, trauma, or neurologic weakness. For intubation, the concern is a potential difficult airway:
  • Difficult direct laryngoscopy / poor glottic view: the tongue may not be displaced adequately from the posterior pharyngeal wall.
  • Difficult mask ventilation or upper-airway obstruction: especially if the tongue or floor of mouth is enlarged, painful, or fixed.
  • Rapid deterioration after induction and muscle relaxation: loss of tone can worsen posterior tongue obstruction, particularly with edema or a mass.
  • Possible difficult rescue airway: floor-of-mouth infection, tongue swelling, or distorted anatomy may also make supraglottic devices and front-of-neck access harder.
Clinical implication: Treat this as an anticipated difficult airway until assessed. Check mouth opening, Mallampati view, thyromental distance, mandibular movement, neck movement, and look specifically for tongue/floor-of-mouth swelling, stridor, dysphagia, drooling, voice change, or infection.
If obstruction or anatomical distortion is suspected, maintain spontaneous breathing, call experienced anesthesia/ENT support, prepare video laryngoscopy and a surgical-airway plan, and consider awake tracheal intubation rather than routine induction. The DAS awake-intubation guidance recommends considering awake intubation when predictors of difficult airway management are present. Textbook guidance also links posterior pharyngeal obstruction by the tongue with intubation difficulty (Tintinalli's Emergency Medicine, airway assessment section).
If the patient currently has stridor, drooling, muffled voice, respiratory distress, or tongue/floor-of-mouth swelling, this is an urgent airway emergency.
