ENT AS Flashcards
1
Q
What types of audiometry are there?
A
Pure tone audiometry (PTA)
Tympanometry
Evoked response audiometry
2
Q
What is pure tone audiometry?
A
Headphones deliver tones at different frequencies and strengths in a sound-proofed room.
Patient indicates when sound appears and disappears.
3
Q
What is tympanometry?
A
Measures stiffness of ear drum
- Evaluates middle ear function
Flat tympanogram: mid ear fluid or perforation
Shifted tympanogram: +/- mid ear pressure
4
Q
What is an evoked response audiometry?
A
- Auditory stimulus with measurements of elicited brain response by surface electrodes
- Used for neonatal screening (if otoacoustic emission testing negative).
5
Q
What is otitis externa presentation?
A
Watery discharge
Itch
Pain and tragal tenderness - acute main on moving the pinna.
Conductive hearing loss if lesion is large.
Inflammation is more likely to be severe if there is:
- a red, oedematous ear canal which is narrowed and obscured by debris
- conductive hearing loss
- Discharge
- Regional lymphadenopathy
- Cellulits
- Fever
Chronic otitis externa
- Chronic discharge from affected ear, hearing loss, and severe pain.
6

Use flucloxacillin for uncomplicated otitis externa if systemic therapy was warranted.
If not responsive do a swab.
If they fail to respond refer to ENT urgently. This is despite strong analgesia therefore suggests malignant otitis externa
Poor response to topical antibiotics should be referred to ENT. This is for microsuction and insertion of a pope wick.

```
No treatment needed in the majority of cases as the tympanic membrane will usually heal after 6-8 weeks. Advisable to avoid getting water in the ear during this time,
Common practise is to prescribe antibiotics to perforations which occur following an episode of acute otitis media.
Myringoplasty may be performed if the tympanic membrane does not heal by itself.
Myringoplasty is the closure of the perforation of pars tensa of the tympanic membrane. When myringoplasty is combined with ossicular reconstruction, it is called tympanoplasty.

Rinne's
Fork is struck causing it to vibrate.
Conductive hearing loss is if bone is louder than air.
114
Sudden unilateral sensorineural hearing loss?
Some evidence that high dose steroids for seven daus improves prognosis.
ENT checks for pure tone audiometry testing to arrange an MRI to exclude acoustic neuroma.
115
Gingival hyperplasia?
Phenytoin
Cyclosporin
CCB - Nifidepine
AML
CIA - CCB (nifedipine), immunosuppressants (ciclosporin), anticonvulsants - phenytoin.
116
Nasopharyngeal carcinoma?
SCC of the nasopharynx
Rare in most parts of the world.
Associated with EPV.
Presenting features
- Systemically = Cervical Lymphadenopathy
- Local = Otalgia, unilateral serous otitis media, nasal obstruciton, discharge and epistaxis, cranial nerve palsies III-VI. Referred pain through V-X
Image = CT and MRi
Radiotherapy = First line
Presents with a painless lymphadenopathy with a tendency to spread early.
Remember the nasopharynx drains to the posterior triangle
Larynx, buccal mucosa and tonsillar fossa drains to anterior triangle.
117
Oral cancer referral?
Consider a suspected cancer pathway referral (for an appointment within 2 weeks) for oral cancer in people with either:
unexplained ulceration in the oral cavity lasting for more than 3 weeks or
a persistent and unexplained lump in the neck.
Consider an urgent referral (for an appointment within 2 weeks) for assessment for possible oral cancer by a dentist in people who have either:
a lump on the lip or in the oral cavity or
a red or red and white patch in the oral cavity consistent with erythroplakia or erythroleukoplakia.
118
Vertebrobasilar ischaemia?
Vertigo upon neck extension = characteristic for this condition and results in falls in elderly patients.
RF: atherosclerosis etc.
119
Sialadenitis
Inflammation of the salivary gland likely secondary to obstruction by a stone impacted in the duct.
Usually due to Staph A.
Duct from the submandibular gland drain into the floor of the mouth. Purulent discharge causes a foul taste in mouth.
3 main salivary glands
- Parotid glands, submandibular glands, sublingual glands.
Disorders of glands occur due to infection, inflammation , obstruction or malignancy.
120
ENT Surgery post op
Haematoma is a complication of surgery that is typically resolved by placement of a drain.
Emergency management is to remove the surgical clips
121
Ludwig's angina?
Cellulitis which occurs on the floor of the mouth of a patient.
Deadly, as it spreads into the fascial spaces of the head and neck.
Swelling ensues from the inflammation begins to push the floor of the mouth upwards and blocks air entry.
Patient has compromised immune system (IVDU puts risk for HIV and AIDS) and poor dentition.
122
Thyroid surgery?
Complications following surgery:
- Anatomical such as recurrent laryngeal nerve damage
- Bleeding. Confined space haematoma's may rapidly lead to respiratory compromised owing to laryngeal oedema.
- Damage to the parathyroid glands resulting in hypocalcaemia.
123
Diphtheria
White film covering tonsils = Diphtheria however patients are NOT systemically well.
124
Gingivitis?
Secondary to poor dental hygiene.
Ranges from simple gingivitis (Painless red swelling of gum margin which bleeds on contact) to necrotizing ulcerative gingivitis (painful bleeding gums with halitosis and punched out ulcers on gums).
Simples = Review by dentist.
Patient presents with acute necrotising ulcerative gingivitis
- Refer patient to dentist
- Oral metronidazole 3 days.
- Chlorhexidine or hydogen peroxide
- Simple analgesia
125
Unilateral middle ear effusion in an adult
Can be presenting symptoms of nasopharyngeal cancer.
Unilateral middle ear effusion in an adult can be a presenting symptom of nasopharyngeal cancer, especially in smokers and people of Chinese or South-East Asian origin. A tumour may cause obstruction of the eustachian tube.
NICE advises you should consider a two week wait referral for patients of Chinese or South-East Asian origin with unilateral ear effusion, if not associated with an upper respiratory tract infection.
126
Tonsillar SCC?
Tonsils are most common site for SCC in the oropharynx. Presents at an advanced stage.
RF = Smoking, high levels of alcohol intake and poor oral hygiene.
HPV (HPV-16) linked to development of tonsillar SCC.
EBV is associated with nasopharyngeal in origin of lymphoma.
127
Rhinitis medicamentosa?
Rebound nasal congestion brought on by extended use of topical decongestants.
Withdrawal of offending nasal spray (cold turkey).
