Q

palpate all the facial bones so you know it is isolated, no imaging if tender only at the nasal bridge, the nose is aligned, the nareas are patent, and there is no septal hematoma, management of most nasal fraftures is deferred until swelling resolves, for extensive facial trauma CT is the preferred imaging modality

A

isolated nasal trauma

Q

common complaint, usually not a sign of systemic disease, common causes include trauma, nosepicking, dry mucosa due to dry winters, allergies, less common causes include coagulopathy, thrombocytopenia, and cancer

Q

not common 1:150,000 people is about 50/year in the US, primarily adolescent males, can present with massive epistaxis or mass effect, benign but grows aggressively

Q

personal history of bleeding issues, blood in the stool or urine, gum bleeding, anticoagulant medications, family history of bleeding disorders, prior episodes on the same side with what triggers them, if treatment was attempted

A

epistaxis history

17
Q

management is done stepwise, apply pressure, add topical vasoconstrictor oxymetazoline, cautery only if you can see the source and only do one side of the septum, then tamponade, then surgical management

A

epistaxis history

18
Q

pressure, topical vasoconstrictor oxymetazoline, cautery if you can see the source, only do one side of the septum, tamponade, surgical management

A

epistaxis management

19
Q

if unable to control pressure +/- topical vasoconstri ction +/- cautery, proceed with packing, can be vaseline gauze or commercial products, packing remains for 24-48 hours, packing remains for 24-48 hours, oral antibiotics are not uniformly recommended but consider for prevention of sinusitis and toxic shock syndrome, may pack both sides if first doesn’t stop it, if still bleeding suspect posterior bleed

A

anterior expistaxis

20
Q

when efforts to stop epistasis as already described don’t work you may have a posterior bleed, posterior pack and also anterior pack, will often need inpatient care

A

posterior epistaxis

21
Q

uncontrolled bleeding or bleeding that recurs when pack is removed may need a surgical or interventional radiology approach

A

if all else fails

22
Q

don’t touch your nose, don’t put anything in your nose like finger, tissue, or gauze, use a humidifier when sleeping, use saline spray, ENT referral if the patient needed more than anterior packing, assess for causes/sources

A

epistaxis after care

23
Q

most common in children, can cause purulent drainage, foul odor, bleeding, and pain, acutely parents can see the child put it there, but subacutely can cause unilateral purulent drainage with bad smell, can be removed with parent’s kiss, balloon catheter, forceps, caveats with button batteries, concern for aspiration, check for other orifices, consider sinus infection

A

nasal foreign body

24
Q

make sure there is only one foreign body, if subacute presentation with purulent discharger, treat with oral antibiotics for presumed sinus infection, consult ENT if injury

A

nasal foreign body aftercare

25
Q

itchy nose, stuffiness, watery nasal discharge, sneezing, itchy etes, seasonal with pollen or perennial, pale boggy mucosa with swollen turbinates and watery nasal discharge, treat with oral medications like antihistamines, and leukotriene modifiers, topical meds intranasally like antihistamines and steroids, or immunotherapy, avoid allergens

A

allergic rhinitis

26
Q
A

nasal polyps

27
Q

generally bilateral in older patients, related to chronid inflammation or infection, red flags include unilateral polyps which may be malignancy, children or young adults with polyps consider underlying disorders like cystic fibrosis, obstructive complains as well as allergy, fullness, decreased sense of smell, treat with topical steroids, oral steroids if very symptomatic, surgical resetction

A

nasal polyps

28
Q

overuse of oxymetazoline and or phenylephrine nasal spray, is real

A

rhinitis medicamentosa

29
Q

deviated septum, perforated septum

A

other causes of nasal obstruction symptoms

30
Q

acute painful inflammation of the entrance to the nose, usually no complaint of obstruction, erythema may have pustule and or crusting, tendnerness, usually cause by s aureus, treat with topical muciprocin or antistaph antibiotic, venous drainage is relevant

A

nasal vestibulitis

31
Q

common cold caused by a variety of viruses, accompanying systemic disease and other respiratory symptoms, course is 7-10 days with congestion thick and sometimes discolored toward the middle of the course, treatment is symptomatic, no antibiotics unless there is a sinus infection

A

acute rhinitis

32
Q

failry common especially as people get older, can lead to loss of enjoyment of food and ultimately malnutrition and depression, obstructive diseases 30% like sinusitis, allergies, polyps, post infetious like 15-30%, with SARS cov-2 most patients who have lost smell recover it spontaneously within a few weeks, trauma 10-30% direct mucosal injury to the CNS anywhere on the pathway, medications, drugs of abuse, aging, CNS disease like alzheimer’s, parkinson’s, multiple sclerosis, stroke, pseudotumor, cerebri, idiopathic, workup is directed by history, may include CT scan to evaluate sinus disease or MRI to evaluate CNS, treatment depends on cause, often no treatment with patience required

A

olfactory dysfunction

33
Q

olfactory neurons > bulb > nerves > nuclei, cortex, and amygdala

A

olfactory pathway
