BOAS Flashcards
(13 cards)
What are the primary components of brachycephalic obstructive airway syndrome?
Stenotic nares
Elongated (+/- thickened) soft palate
Hypoplastic trachea
Aberrant nasal turbinates
Redundant pharyngeal folds
Macroglossia
What are the secondary components of brachycephalic obstructive airway syndrome?
Everted laryngeal saccules
Everted tonsils
Laryngeal collapse
GI disease: regurgitation, sliding hiatal hernias, gastritis, inflammatory GI disease
Which components of brachycephalic obstructive airway syndrome are most commonly treated surgically?
Stenotic nares
Elongated soft palate
Everted saccules
Everted tonsils
Aberrant nasal turbinates
Laryngeal collapse
How is an elongated soft palate treated surgically?
Staphylectomy
Folded flap palatoplasty (long and thick)
How are stenotic nares treated surgically?
Vertical wedge resection
Punch bx
Nares amputation
Alapexy
How are everted saccules treated surgically?
Sacculectomy - BUT CONTROVERSIAL - LOTS OF COMPLICATIONS
How are everted tonsils treated surgically?
Tonsilectomy
How is laryngeal collapse treated surgically?
Laryngeal tie back (cricoarytenoid lateralization)
Permanent tracheostomy
How are aberrant nasal turbinates treated surgically?
Laser ablation
WILL PROBABLY GROW BACK
Why do dogs with BOAS also present with GI signs?
Regurgitation, sliding hiatal hernias, gastritis
Due to high negative pressure
What is the ideal time to surgically treat dogs with BOAS?
Treat early (6 months) to prevent/minimize laryngeal collapse
Which anatomic landmarks are used to determine if the soft palate is an appropriate length?
Soft palate should barely interact with the epiglottis
Use palatine tonsils as landmark when patient is intubated
How do you prevent laryngeal collapse in dogs with BOAS?
Prevention is best!!
Treat treatable conditions
