A classification system for airway compromise due to bilateral vocal fold mobility impairment.
We present a system for classification of bilateral vocal fold mobility impairment. Type 1 obstructions are caused by bilateral laryngeal denervation, most commonly due to bilateral recurrent laryngeal nerve palsy. Type 2 obstructions are caused by crico-arytenoid joint ankylosis. Type 3 obstructions are due to inter-arytenoid granulation tissue. Type 4 lesions are caused by mature inter-arytenoid scar tissue and type 5 lesions are complex or total laryngeal stenoses.
