ENT Flashcards
(95 cards)
Nasal blockage
Common causes in adults
- Infective rhinosinusitis (acute/chronic)
- Allergic rhinitis
- Non-allergic rhinitis (e.g., vasomotor)
- Nasal polyps
- Deviated nasal septum
- Tumours (e.g., inverted papilloma, nasopharyngeal carcinoma)
Nasal blockage
key history features
- Duration: acute vs chronic (>12 weeks = chronic)
- Associated symptoms: facial pain, discharge, anosmia
- Allergy history: sneezing, itchy eyes
- Laterality: unilateral (consider neoplasm or polyp)
- Systemic symptoms: red flags for malignancy
Rhinitis
Allergic vs non-allergic differentiation
Allergic:
- itchy nose/eyes,
- sneezing,
- clear discharge,
- seasonal pattern,
- family/personal atopy
Non-allergic:
- nasal congestion,
- postnasal drip,
- triggered by irritants (smoke, perfumes),
- no itch or sneezing
allergic rhinitis
basic mx
- Allergen avoidance
- Intranasal corticosteroids (first-line)
- Oral antihistamines
- Saline nasal irrigation
- Consider referral for immunotherapy if severe
epistaxis
common causes
(local and systemic)
Local:
- trauma (nose-picking)
- dry mucosa
- infection
- nasal polyps
- tumour
Systemic:
- hypertension
- anticoagulants
- coagulopathy (e.g. liver disease thrombocytopenia)
epistaxis
Mx of anterior epistaxis
- First aid: pinch soft part of nose, lean forward
- Topical vasoconstrictor + silver nitrate cautery if visible vessel
- Nasal packing if persistent
- Refer ENT if posterior or recurrent bleeds
deafness
common causes (conductive)
- wax
- otitis media
- otitis externa
- perforated TM
- otosclerosis
- cholesteatoma
deafness
common causes (sensorineural)
- presbycusis
- noise exposure
- Ménière’s
- vestibular schwannoma (acoustic neuroma)
- ototoxic drugs
- sudden sensorineural hearing loss
- labyrinthitis
hearing loss
Rinnes test
air vs bone conduction
- Normal/sensorineural: AC > BC (positive)
- Conductive: BC > AC (negative)
hearing loss
weber’s test
lateralisation
- Conductive: lateralises to affected ear
- Sensorineural: lateralises to unaffected ear
hearing loss
investigations
- Otoscopy
- Pure tone audiometry
- Tympanometry
- MRI head (if unilateral sensorineural loss to rule out schwannoma)
Otalgia (ear pain)
common causes
- Otitis externa
- Acute otitis media
- Foreign body
- Mastoiditis (complication)
- referred pain
otalgia
reffered causes of pain
- Temporomandibular joint dysfunction
- Dental infection
- Pharyngeal or laryngeal cancer (via glossopharyngeal/vagus nerve)
- Cervical spine pathology
throat pain
common causes of sore throat
- Viral or bacterial pharyngitis/tonsillitis
- Infectious mononucleosis
- Quinsy (peritonsillar abscess)
- Epiglottitis (life-threatening)
- Malignancy (if persistent/unilateral with red flags)
throat pain
red flags for malignancy
- Persistent sore throat >3 weeks
- Dysphagia or odynophagia
- Unilateral symptoms
- Weight loss,
- hoarseness
- Neck lump
difficulty swallowing (dysphagia)
oropharyngeal dysphagia features
- difficulty initiating swallow,
- coughing/choking,
- neuromuscular cause
dysphagia
oesophageal dysphagia features
- food sticking after swallowing,
- progressive with solids → liquids,
- consider cancer
dysphagia
red flags (need referral)
- Progressive symptoms
- Weight loss
- Hoarseness
- Neck lump
- Age >55 with new onset
neck lumps
common causes
- Reactive lymphadenopathy (infection)
- Malignancy (H&N SCC, lymphoma, metastases)
- Congenital (thyroglossal cyst, branchial cyst)
- Thyroid nodule or goitre
- Salivary gland pathology
neck lumps
Ix
- Full head and neck exam including oral cavity
- Flexible nasoendoscopy
- USS neck + FNA
- Consider CT if malignancy suspected
hoarseness
common causes
- Acute laryngitis (viral)
- Vocal cord nodules/polyp (voice overuse)
- Recurrent laryngeal nerve palsy (e.g. malignancy, thyroid surgery)
- Laryngeal carcinoma (esp. if >3 weeks)
- GORD
vertigo
key differentials
- BPPV (brief episodes triggered by head movement)
- Vestibular neuritis (acute onset, post-viral, no hearing loss)
- Ménière’s disease (recurrent, with tinnitus and hearing loss)
- Vestibular migraine
- Acoustic neuroma
vertigo
examinations and invx
- Ear exam: otoscopy
- Neurological exam (Romberg, gait)
- Dix-Hallpike manoeuvre for BPPV
- HiNTS
- Audiometry
- MRI head if unilateral hearing loss or persistent symptoms
HiNTS - what tests?
-
Head impulse:
+ve if vestibular, -ve if central -
Nystagmus:
Unilateral horizontal = peripheral cause. Bilateral/vertical = stroke -
Test of Skew:
Abnormal movement = central cause
