what are some primary disorders associated with BOAS? (brachycephalic obstructive airway syndrome) [stenotic nares etc…]
-stenotic nares [good indicator for how the rest of airway will be]
-aberrant nasal turbinates

what are the 3 stages of laryngeal collapse?
- Stage 1: everted laryngeal saccules
- Stage 2: (corniculate) processes contact
- Stage 3: cuneiform processes contact and flap over each other
what are some techniques for BOAS management? [brachycephalic ocular airway syndrome]
weight loss
-prevent stress, exercise, heat
-use harness
-surgical correction[rhinoplasty, etc.]
a folded flap palatoplasty can be used for correction of which structure association with BOAS?
elongated soft palate
laryngeal paralysis is due to failure of the _________muscle [not the cartilage, like laryngeal collapse]
this muscle is innervated by which nerve?
Surgical salvage Tx?
Dorsal cricoarytenoid muscle
-Innervated by the recurrent laryngeal nerve
Arytenoid lateralization (total salvage)
what are some (4) clinical signs of laryngeal paralysis?
-progressive inspiratory stridor
-dysphonation
-exercise intolerance
-increased risk of aspiration pneumonia
-often collapse
