H&N Flashcards by Joanna Lumb

Gland anatomy

parotid: serous gland; supf/deep lobes; ostium 2nd upper molar; CN VII, ECA, LN

subM: mixed mucoserous; Wharton’s duct; papilla in mouth under tongue; CN V2/V3, facial artery

subL: smallest major gland; mucous; 10-15 ducts, direct into mouth or via Wharton’s

sialadenitis

bacterial; systemic, pain, swelling (gland and mouth), pus;
RF: dehydration, old age, poor hygiene
Rx: ABx (HD), fluids, hygiene, sialogogues/citrus (flow)
complications: abscess (drain), chronic infection

sialolithiasis

stones, usually from chronic infection
subM commonest (thick mucoserous)
postprandial pain and swelling, repeated infection, tender and swollen, ?palpable stone
Rx: XR +/- dye; PO fluids + sialogues (pass stone); fail/deteriorate = surgery

Sjogren’s

multisystem AI disease; 1o/2o (CTD, SLE, scleroderma)
serostomia, keratoconjunctivitis, glossitis, stomatitis, no secretion, candidiasis, stones risk
diffuse parotid swelling
Dx: Bx, Schirmers (lacrimation), Carisson-Crittendon (saliva), Ag/HLA
Rx: symptoms (tear drops, steroids, parotidectomy)

malignant SG

rapid growth, pain, CN VII palsy (Ca UPO!), LN mets
subL/subM > Parotid; SM/SL less common than parotid tumours but more likely malignant

adenoid cystic: commonest; 40-60y; 14% of parotid tumours; slow circ’d fibrous; poor prognosis
mucoepidermoid
adenocarcinoma: aggro; poor prognosis
lymphoma: NHL >HL; 50-70y; rubbery, rapid, B symptoms
mets: lung, breast, kidney, upper GI, melanoma, SCC

benign SG

tumours 80-90% in parotid, 80-90% benign
slow, painless masses, no nerve palsy, smooth mobile mass

pleomorphic adenoma: commonest; transformation; cystic lobulated blue/grey

infection vs. benign vs. malignant

inflammatory: systemic
benign: slow painless
malignant: fast, painful, nerve palsy, LN

SG investigations and managemet

baseline bloods and cultures
FNAC + excision biopsy

excision: benign/low grade Ca
radical resection + RDT: high grade Ca
surgical risks: CN VII, haematoma, fistula, Frey’s syndrome (cross salivary and sweat)
