ENT and endoscopy Flashcards
(20 cards)
management for coin and battery ingestion (not button battery)
most will pass in stool; if still in stomach at 2 weeks, endoscopic retrieval is warranted
emergent endoscopy for foreign body indications:
esophageal obstruction with inability to handle oral secretions, disk batteries in esophagus, sharp pointed objects in esophagus
true or false. aspirated peanuts break down to peanut oil which is an intense irritant of the airway and can lead to pneumonitis
true. patients must be monitored after cases as an inpatient until symptoms resolve
what types of polyps require follow up with repeat colonoscopy in 3 years
single tubular adenomas >10mm multiple tubular adenomas 3-10mm adenomas with villous features sessile polyps serrated adenomas
damage to what during a surgical airway can result in vocal cord dysfunction or paralysis
thyroid cartilage
initial treatment of chyle leak from neck dissection:
low fat diet or medium chain fatty acid diet; or NPO with TPN
only absolute contraindication to bronchoscopy
severe refractory hypoxia
most common complication of PEG placement
infection at the site
most common indication for parotidectomy
neoplasm
cyst-like lesion of temporal bone that contains epithelium and desquamated keratin; presents with foul otorrhea and requires surgical resection
cholesteatoma
most common cancer of upper lip
basal cell carcinoma
most common cancer of lower lip
squamous cell carcinoma
signs of damage to recurrent laryngeal nerve on laryngoscopy
ipsilateral adduction of vocal cord (moved to midline trachea)
what does the superior laryngeal nerve innervate
cricothyroid
most common type of branchial cleft cyst
second branchial cleft arising in mid- to lower neck along anterior border of SCM
what nerve arises from C3-C5, courses anterior to the anterior scalene and posterior to the subclavian vein as it enters the thorax
phrenic nerve - motor innervation to diaphragm; sensory innervation to pericardium and diaphagmatic pleura
location of neck lymph nodes
level 1 - submental level 2-4 - upper, middle, and lower jugular level 5 - posterior triangle of the neck level 6 - central compartment level 7 - superior mediastinal
Frey syndrome cause
aberrant regrowth of parasympathetic nerve fibers associated with the auriculotemporal nerve into the sweat glands of the skin overlying the parotid gland
Symptoms of Frey syndrome
sweating and flushing on the cheek or temple or near the ear particularly when eating foods with intense flavors (sour, spicy, salty)
What nerve is often sacrificed during mobilization of the inferior pole of the parotid for parotidectomy
greater auricular nerve (provides sensation to lower earlobe and post-auricular skin)
