Resp 3 Flashcards
Sinusitis
-primary= viral or bacterial
-secondary= dental disease, cyst, neoplasia, foreign body, trauma
Things indicating upper airway disease
-upper respiratory tract infections
-trouble eating, weight loss (dental disease)
-unilateral nasal discharge (sometimes bilateral)
Physical exam for upper airway disease
-nasal discharge
-sinus percussion
-submandibular lymph nodes
-perform xray/CT- determine drainage/fluid line… should be tracts that are black/air (no fluid). Also check for neoplasia
Guttural pouch diseases
-empyema- fill with pus
-mycosis
What is medial guttural pouch in contact with?
-internal carotid artery
-cranial cervical ganglion
-cranial nerves IX,X,XI, XII
-sympathetic nerves
-retropharyngeal lymph nodes
-recurrent laryngeal nerve
-external carotid artery
What cranial nerves are close to the stylohyoid bone ends in the temporohyoid joint?
-Facial (VII)- muscles of head
-vestibulocochlear (VIII)- hearing/balance
Where does the opening of the guttural pouch occur?
-located dorsolateral aspect of pharynx
What is the lateral compartment of guttural pouch in contact with?
-maxillary artery
-caudal auricular artery
-superficial temporal artery
What does damage to CN IX, X cause?
-nasopharyngeal dysfunction
-dysphagia
What does damage to recurrent laryngeal nerve result in?
-unilateral laryngeal hemiplegia
Damage to sympathetic nerve fibres?
-Horner’s syndrome (miosis, ptosis of upper eye lid, protrusion of 3rd eyelid, sweating of cranial neck + base of ear)
Exercise induced pulmonary hemorrhage
-occurs in horses
-hemorrhage into the lungs
-bleeding from nostrils
DDx: guttural pouch erosion, Ethmoidal hematoma
Key things to look for for facial nerve paralysis
-ear droopy
-eyelid droopy
-lip droopy
