Name 3 things to look for on inspection of the ear
Pre-auricular - scars (parathyroidectomy, middle ear surgery), swelling (infection, parotid tumour), erythema (infection), sinuses, pits, fistulae
Pinna - erythema and swelling (infection, haematoma), tenderness
Post-auricular - scars, painful swelling (mastoiditis, lymphadenitis)
What features of the tympanic membrane should be assessed on otoscopy?
Presence of light reflex
Colour - red (inflammation), white (sclerosis)
Position - retracted (cholesteatoma, infection), bulging (infection), perforation
Ossicles - visible malleus, incus and stapes or not
What is pneumatic otoscopy?
Otoscope with air tight seal and rubber bulb which allows pressure to be altered within the ear canal
If the patient can hear a whisper at 60cm during a free field hearing test, approximately how good is their hearing?
Better than 30dB
If the patient can hear a whisper at 60cm during a free field hearing test, approximately how good is their hearing?
Better than 30dB
What does Weber’s test show?
If sound is louder in one ear, there is a conductive hearing loss in that ear OR sensorineural hearing loss in the other ear (Rinne’s test will confirm which)
If a patient has a unilateral conductive hearing loss, the tuning fork sound will be heard louder in the deaf ear
If a patient has a unilateral sensorineural hearing loss, the tuning fork sound will be heard louder in the normal ear
What does Rinne’s test show?
If sound is louder via bone conduction, there is an external/middle ear disease affecting air conduction
How can the nose be anatomically divided to aid inspection?
Bony pyramid/upper 3rd
Cartilaginous pyramid/middle 3rd
Lobule/lower 3rd
How should the nose be inspected on examination?
Front - shape, deviation from midline, scars, skin changes
Side - bump, collapse, projection, rotation of tip (up or down)
Below - symmetry, deviations, scars
Give 3 things which may be seen on anterior rhinoscopy
Septal deviation Swelling (rhinitis causing enlarged inferior turbinates, oedema and clear rhinorrhoea) Septal perforations Prominent blood vessels Polyps in middle meatus
What is nasal misting?
Assess degree of misting on metal surface to check airflow and patency
What structures are found in the post-nasal space?
Adenoid pad
Fossa of Rosenmuller
Eustachian tube orifice
If a neck mass moves on swallowing, what does this suggest?
Thyroid origin (e.g. goitre, thyroglossal cyst)
If a neck mass moves on tongue protrusion, what does this suggest?
Thyroglossal cyst
What is Pemberton’s test?
Test for a retrosternal goitre that may obstruct
the thoracic outlet and superior vena cava
A positive sign is
congestion of facial/neck veins and hoarse voice upon raising the
arms
What is the blood supply of the external ear?
Auriculotemporal branch of superficial temporal artery
Posterior auricular branch of external carotid artery
What is a cauliflower ear?
Cartilage necrosis which occurs when cartilage is separated from overlying perichondrium (e.g. due to infection, blood, trauma) from which it derives nutrients
What part of the ear communicates with the nasopharynx via the Eustachian tube?
Middle ear
What is presbycusis?
Decreased ability to detect high pitched sounds with increasing age
What is a distinguishing feature of true vertigo?
Sensation of spinning and movement of surrounding environment
What are the 3 most common causes of vertigo originating from the labyrinth?
Benign paroxysmal positional vertigo
Vestibular neuritis
Meniere’s disease
What are the main signs/symptoms of BPPV?
Sudden onset
No hearing loss
Hallpike test positive
Rotary vertigo on moving head
What are the main signs/symptoms of Meniere’s disease?
Gradual onset Fluctuating hearing loss Rotary vertigo Tinnitus worse during episode Aural fullness before onset of vertigo
What are the main signs/symptoms of vestibular neuritis?
Sudden or gradual No hearing loss Rotary vertigo continuous for >24 hours Associated nausea and vomiting Confined to bed Several days/weeks to resolve
