Disease of Head and Neck - Mouth and Upper Airway Flashcards

1
Q

Caries

A

Tooth Decay
Common

Bacteria ferment sugars and produce acids that dissolves minerals in enamel

Prevention - Brushing, fluoride forms fluorapatite in enamel which increases resistance to bacterial acids

Q

Gingivitis

A

Inflammation of sqamous mucosa - edema and bleeding
Cause - improper oral hygiene - plaque formation (bacteria, saliva protein and cell debris)
Prevention - brushing flossing

Can cause tooth loss, sepsis, infective endocarditis, local and systemic abscesses

Higher risk in immunecompromised pts - AIDS, Diabetes, Crohn’s, leukemia,

16
Q

Squamous cell carcinoma

A

Most common cancer of mouth!
Predisposing factors - Tobacco, Alcohol and HPV
Precursors - leukoplakia and Erythroplakia
Often diagnosed after invasion/metastasis has occurred
Field cancerization
met - lymph, lung, liver bone

17
Q

Leukoplakia

A

White patch that doesn’t scrape off
clinical presentation hyperkeratosis
dysplasia is seen. should be considered premalignant until proven otherwise

18
Q

Erythroplakia

A

Red, often ulcerated or eroded lesion

Can become cancerous

19
Q

Odontogenic cysts and tumor

A

Arising in tissues that form teeth
tumor is rare (both benign and malignant)
most common lesions include dentigerous cysts, keratocysts, ameloblastoma

20
Q

Dentigerous Cyst

A

Cyst that originates around an unerupted tooth
Squamous lining
Complete excision is curative
can recur if incompletely excised

21
Q

odontogenic keratocyst (OKC)

A

More locally aggresive than odontogenic cyst
High recurrence rate in parakerotic variant
Multiple OKC + Many cutaneous basal cell carcinoma - Nevoid basal cell carcinoma syndrome

22
Q

Ameloblastoma

A

Low grade malignant tumor from odontogenic epithelium
Locally invasive tumor
Recurs if not completely excised
metastases rare

23
Q

Rhinitis

A

Inflammation of nasal mucosa
Caused by viruses - adeno, echo, rhino
can get secondary bacterial infections

24
Q

allergic rhinitis

A

hypersensitivity to pollen, fungi etc
IgE mediated
Eosinophils

25
Q

Chronic rhinitis

A

Repeated infections or allergic rhinitis
More severe superimposed bacterial infections that extend into sinuses

LEAD TO NASAL POLYPS

26
Q

Nasal inflammatory Polyps

A

After chronic rhinitis
Edematous mucosa orinflamed stroma
Can ulcerate and grow quite large

27
Q

Pharyngitis and Tonsillitis

A

Viral - rhino, echo, adeno, influneza
Bacteria - strep and staph

Strep can cause - RF and then RHD
Post streptococcol glomerulonephritis

28
Q

Angiofibroma

A

Nasopharyngeal tumor - benign
Exclusive to adolescent males
androgen receptor positive
Bleeds easily and profusely *

29
Q

Olfactory Neuroblastoma (Esthesioneurblastoma)

A

Malignant neuroblastic tumor of olfactory nerve
any age - median 50
bad prognosis - depending on grade and stage

Long cytoplasmic processes - fibrillary background

30
Q

Nasopharyngeal carcinoma

A

African childhood cancer *
Also in Chinese
Risk factor - EBV, nitroamines in diet and smoking
Three histologic types (based on differentiation
keratinizing squamous - least radiosensitive
Non keratinizing squamous
Undifferentiated - most radiosensitive

Up to 70% - lymph node metastasis
this tumor if patient has squamous or undifferentiated carcinoma in cervical nodes without a known primary

otitis media in adults - think of this
epistaxis, local invasion of cranial nerve VI

31
Q

sinusitis

A

most common caused by viruses as part of common cold
Chronic - secondary bacterial infection
preceded by rhinitis

Can cause meningitis

32
Q

Unusual Sinusitis

A

kartagener syndrome - defective ciliary action - bronchiectasis ans situs inversus

Fungi - diabetes or IC
if aggresive and necrotizing - consider mucormycosis

33
Q

Murcormycosis

A

aka zygomycosis
Bread mold fungi
Mucor, rhizopus, absidia, cunninghamella
In IC

34
Q

Sinonasal papilloma

A

Benign tumors of squamous mucosa
Two Types
Exophytic - more common
Inverted - high recurrence ! more aggressive
