Study These Flashcards
A 
Smoking
Alcohol
Age > 40
HPV
EBV
GERD
Chinese ethnicity
Plummer Vinson Syndrome
23
Q

What are primary tumors of the neck?

Study These Flashcards
A 
Lymphoma
thyroid carcinoma
Salivary gland neoplasms
Schwannaoma
Paraganglioma
Lipoma
24
Q

What are the deep neck abscesses and who gets them?

Study These Flashcards
A

Peritonsillar (kids > 10) - no airway obstruction usually
Retropharygneal (kids < 10) - cause cause airway obstruction
Parapharyngeal (all ages: dental infections, tonsillitis)

25
What is the first step in workup of a neck mass?
Thorough head and neck exam: test all CNs
26
After physical exam, what is the next step to workup a neck mass?
Flexible endoscopy: eval for primary tumor
27
After flexible largyngoscopy, what is the next step to eval for neck mass?
FNA biopsy, CT scan with contrast of head/neck
28
After FNA and CT head/neck, what next for neck mass to stage or look further?
chest CT, PET scan, CXR to see what else is present
29
What to do if primary tumor cannot be found for a neck mass?
Panendoscopy: complete endoscopic eval or upper aerodigestive tract: laryngoscopy, esophagoscope and bronchoscopy
30
What is the order of the workup for neck mass?
1 Full PE with CN testing 2 Flexible laryngoscopy 3 FNA biopsy/CT scan with contrast of head/neck 4 Chest CT, PET scan, CXR 5 Panendoscopy if primary can still not be located
31
When is open neck biopsy done for neck mass?
After complete workup, including panendoscopy | - Due to increased risk of local/distant recurrence, increased morbidity, seeding of tumor cells
32
What are key tipoffs for a malignant neck mass caused by cancer?
Unilateral neck mass: progressive in size, age > 40y | Unilateral otalgia, Dysphagia, Odynophagia, Dysphonia, Dyspnea, Trismus, stridor, hemoptysis
33
What are symptoms of acute otitis media?
``` Otalgia Fever Hearing loss Tinnitus Bulging and erythematous TM w/ decreased mobility, poor light reflex < 3 weeks ```
34
What are symptoms of otitis media with effusion (OME)?
Middle ear effusion w/o signs of acute infection | Hearing loss
35
What are symptoms of chronic otitis media (COM)?
Recurrent or chronic ear infections that result in perforation of the tympanic membrane +/- otorrhea
36
How does otitis external present?
Recent contact w/ warm water Tender, swollen pinna Erythematous ear canal
37
What might regression in language suggest in kids?
Early sign of hearing loss
38
What are 3 roles of Eustachian tubes?
1. Maintain gas pressure homeostasis within the middle ear 2. Prevent infection of the middle ear and reflux of contents from the nasopharynx 3. Clears middle ear infections
39
What organisms cause acute otitis media?
S. pneumoniae Nontypeable H. flu Moraxella catarrhalis
40
What causes otitis media with effusion?
1. residual fluid from suppurative AOM | 2. isolated ETD
41
How does nasopharyngeal carcinoma present?
unilateral OME in adults, more common in China, assoc. with EBV
42
What is the best way to diagnose AOM?
H&P w/ otoscopy
43
What is the best way to diagnose otitis externa?
H&P w/ otoscopy
44
What is best way to diagnose OME?
Pneumatic otoscopy less invasive than myringotomy | - Adults: nasopharyngoscopy to eval for tumors obstructing ET
45
What is treatment of AOM?
Antibiotics
46
What is treatment generally of OME?
None: self resolve w/in 3 months
47
When are PE tubes used for OME?
1 Symptomatic OME >3 months 2 Recurrent AOM with OME 3 Bilateral OME w/ hearing impairment 4. OME w/ vestibular problems, poor school performance, behavioral problems, otalgia
48
What is most significant complication of OME?
conductive hearing loss
49
What are long-term complications of untreated OME?
``` Permanent hearing loss ruptured TM mastoiditis temporal bone osteomyelitis meningitis sigmoid sinus thrombosis brain abscess ```
50
What to consider in any pediatric patient with unilateral aural fullness or otalgia?
Foreign body obstruction
51
Any delay in language milestones, what is the next step?
Eval for hearing loss without an audiology consult
