Tonsillitis

Page 3: Throat Powerpoint

• Acute, subacute (3 wks – 3 mths: Bacterium Actinomyces), chronic.

• Signs /Symptoms: Red, swollen tonsils White patches may appear Severe sore throat, pain at tonsil area Painful/ difficult swallowing Headache Fever and chills Enlarged and tender lymph nodes Loss of voice

Page 4: Throat Powerpoint

• CausesBacterial: Viral: Superinfection

• Treatment Analgesia, lozenges ± antibiotics

• ComplicationPeritonsillar abscess (quinsy)TonsillolithHypertrophy

Page 5: Throat Powerpoint

STRIDOR

• High pitched sound resulting from turbulent air flow in upper airway. May be inspiratory, expiratory or both.– Croup– Acute epiglotitis– Acute airway obstruction

• Larynx : Cricoid cartilage (non-compliant cartilage) & subglottis (narrow)

Page 6: Throat Powerpoint

Page 7: Throat Powerpoint

Acute airway obstruction

• Overcome by skilled intubation or needle cricothyrotomy in children : jet oxygen at 15L/min through a wide bore cannula(14G) placed in cricothyroid membrane.

• Surgical cricothyrotomy• Need tracheostomy – because jet

oxygenates rather than ventilates, so CO2 builds up.

Page 8: Throat Powerpoint

Hoarseness

Medical term : Dysphonia (Abnormality in voice quality)

Page 9: Throat Powerpoint

• Commonly voice overuse or laryngitis.

• If > 3 weeks – laryngeal carcinoma until proven otherwise.

• Causes ( refer table)

Neoplastic Vocal cord, laryngeal papilloma, squamous cell cancer of larynx.

Inflammatory GORD laryngitis, laryngitis (viral, bacterial, allergic, tubercular/ fungal)

Neurological VC paralysis, spasmodic dysphonia, essential tremor, PD, CVA,

Misc. Vocal abuse, VC atrophy, VC scarring, hypothyroidism, Reinke’s oedema, drugs.

Page 10: Throat Powerpoint

Singer’s Nodules• Benign, small swellings situated on

the apposing surfaces of the true cords, commonly at the junction of the anterior one-third and posterior two-thirds

• Symmetrical• Swellings are made of keratin and

result from constant banging together of the vocal cords due to vocal overuse - as in singing, teaching - or abuse - poor speed production.

• Speech therapy, surgery.

Page 11: Throat Powerpoint

Laryngeal carcinoma• Incidence : 1 in 100 000• Elderly, almost always smokers, may be heavy

drinkers, chews tobacco/betel. M>F• Main features :

– 60% in glottis (good prognosis), present early with hoarseness

– Dysphagia– Lump in neck, earache, persistent cough– Squamous cell carcinoma– Early detection has 90% 5 year cure rate– Mx Radiotherapy, resection.

Page 12: Throat Powerpoint

Head & Neck Tumours• Acoustic neuroma (vestibular

schwannoma)

• Progressive, ipsilateral tinnitus ± SN deafness, giddiness.

• May have increased ICP signs, facial numbness, CN V, VI, VII may be affected.

• Test : MRI

• Rx : Surgery

Page 13: Throat Powerpoint

DYSPHAGIA

difficulty in swallowing food or liquid, the cause of which may be

local or systemic

Page 14: Throat Powerpoint

Odynophagia –painful swallowingGlobus – sensation of lump in the throatPhagophobia – psychogenic dysphagia

Functional dysphagia

• Common in – Elderly – Stroke patients– Head and neck ca– Progressive neuro

disease : PD, MS or ALS.

Dysphagia

Mechanical block Motility disorders

Others-Oesophagitis

(infection, reflux)- Globus hystericus

Page 15: Throat Powerpoint

Mechanical Block

• Malignant Stricture– Cancer (Oesophageal, gastric, pharyngeal)

• Benign stricture– Oesophageal web or ring– Peptic stricture

• Extrinsic pressure– Lung ca– Mediastinal LN– Retrosternal goitre– AA– LA enlargement

• Pharyngeal pouch

Page 16: Throat Powerpoint

Motility disorders

• Achalasia• Myasthenia gravis• Diffuse oesophageal

spasm• Palsy (bulbar/

pseudobulbar)• PD• Stroke

Page 17: Throat Powerpoint

• Key questions :– Difficulty swallowing solids & liquids from the start?– Difficult to make swallowing movement?– Odynophagia?– Intermittent, constant or worse?– Neck bulge or gurgle on drinking?

• Examination :– Cachexic/ anaemia– Mouth– Feel for supraclavicular nodes– Look for Sx of systemic disease

Page 18: Throat Powerpoint

• Investigation : – FBC, U&Es– CXR (mediastinal fluid level, absent gastric

bubble)– Barium swallow– Upper GI endoscopy and biopsy– ENT opinion if suspected pharyngeal cause

Page 19: Throat Powerpoint

Facial Palsy

Page 20: Throat Powerpoint

Causes

Intracranial :-Brainstem tumours

-Strokes-Polio

-Multiple sclerosis-CBP angle lesions (acoustic neuroma,

Meningitis)

Intratemporal:-OM

-Ramsay-Hunt-- cholesteatoma

Infratemporal:-Parotid tumours

-Trauma

Others: -Lyme disease

-GB-Sarcoid-Herpes

-Diabetes-Bell’s palsy

Page 21: Throat Powerpoint

Examination & Tests• Check:

– Face : paralysis, weakness– Mouth : loss of lacrimation, taste and reduced

saliva production– Ears : exclude OM, zoster, cholesteatoma – Parotid

• Consider temporal bone radiography & EMG

Page 22: Throat Powerpoint

Ramsay Hunt syndrome

• Also known as herpes zoster oticus

• Severe otalgia (elderly), preceding CNVII palsy.

• Zoster vesicles appear around ear, deep meatus.

• May have vertigo and sensorineural deafness

Page 23: Throat Powerpoint

Bell’s palsy• Viral polyneuropathy with demyelination : affect V, X, C2

nerves• Abrupt onset, associated with pain• Mouth sags, dribble, taste impaired and watery 9dry)

eyes.• Cannot wrinkle forehead, blow forcefully, whistle, or pout

cheeks.• Treatment :

– Protect eye– Prednisolone + oral acyclovir– Surgical exploration

Page 24: Throat Powerpoint

Lumps in the neck

• Refer to ENT– Neck lump clinic : FNA for cytology– CT/ MRI– USS shows lump consistency– Culture specimen for TB

• Diagnosis :– How long present?– Which tissue layer is the lump? Intradermal?– Location?

Page 25: Throat Powerpoint

LUMPS

MIDLINE:- cysts

SUBMANDIBULAR:-Lymphadenopathy

- Salivary stone-Tumour

-Sialadenitis

ANTERIOR:-Cysts

-Tumour (parotid)

POSTERIOR: -Nodes

-Cervical ribs

Page 26: Throat Powerpoint

Salivary Glands

Page 27: Throat Powerpoint

• History & examination :– Dry mouth/eyes– Lumps– Swelling related to food– Pain– Look for external swellings, secretions– Bimanual palpation for stones, test VII nerves,

regional nodes– *mumps, acute parotitis, stones, Sjogren’s

tumours*

Page 28: Throat Powerpoint

Dry Mouth (xerostomia)• Signs

– Dry, atrophic, fissured oral mucosa– Discomfort, difficulty eating, speaking,

wearing dentures– No saliva pooling in floor of mouth– Difficulty expressing saliva from major ducts

• Complications– Dental caries– Candida infection

Page 29: Throat Powerpoint

• Causes :– Drugs : tricyclics, antipsychotics, -blockers, diuretics, hypnotics– Mouth breathing– Dehydration– Head & neck radiotherapy– Sjogren’s syndrome, SLE, scleroderma,– Sarcoidosis– HIV/AIDS– Obstruction– Graft-versus-host disease

• Management:– Increase oral fluid intake; frequent sips– Good dental hygiene: avoid acidic drinks/food– Try saliva substitute– Chewing sugar-free gum or sweets– Pilocarpine rarely satisfactory– Irradiation xerostomia
