ENT Flashcards
What should you do about this?
(present for 2 weeks)
Advise referral to an oral maxillofacial surgeon for excision of the lesion to send for histopathology
Define Chronic Suppurative Otitis Media
This is when there is an ear infection with a perforation and it has been discharging for greater than 6 weeks
What is the management of Chronic Suppurative Otitis Media?
If < 6 weeks then
Dry Aural Toilet, and if signs of AOM then use topical antibiotics
If > 6 weeks then
1. Dry Aural Toilet can be done every 6 hours until canal is dry
- Instil 5 drops of ciprofloxacin 0.3% ear drops of the right ear twice a day after dry mopping until there has been no discharge for 3 days (1)
- Refer to an Ear Nose and Throat surgeon for assessment to rule out cholesteatoma (or chronic osteitis)
What is the difference between OME and AOM with otorrhea?
In terms of otitis media.
AOM: acute otitis media
AOM= middle ear effusion AND Middle ear inflammation, accompanied by pain
- OME: otitis media with effusion
This is when fluid is present for weeks after the resolution of the AOM (acute otitis media) i.e no middle ear inflammation - AOM with otorrhea. This is when there is discharge ,(but after clearing it up) and there are signs of middle ear inflammation.
What is this?
What is the management?
Otitis Media with effussion.
if < 3 months and no report of hearing difficulties, can reassure most will resolve
(if there are significant hearing difficulties or on exam you see TM retraction or cholesteotoma then refer to ENT)
if > 3 months, then do a formal hearing test. If conductive hearing loss, especially in both ears, or noticeable hearing loss or even behavioural difficulties that have arisen refer to an ENT.
What symptoms make An Acute rhinosinusitis more likely to be bacterial?
Severe localised pain
Unilateral pain
Double sickening. Significantly worse after initial recovery
fevers > 39dC for days in a row
Symptoms over 7 days
Purulent and discoloured discharge
Management for ARS
(7)
Simple analgesia
Saline nasal rinses
Decongestants - intranasal such as phenylepherine
Ipratropium (if rhinorrhea predominant) 44 micrograms/spray, 2 sprays each nostril BD
Intranasal steroids: Fluticasone propionate (adult or child 12 years or older) 100 micrograms into each nostril, daily for 4 weeks, then 50 micrograms daily
Avoid smoking and air pollution
Education
What is post viral sinusitis ?
How to you approach management?
Sinusitis that lasts over 10 days but not quite 12 weeks.
Need Sudden onset of symptoms
AND
any of: nasal blockage, congestion, discharge, obstruction
AND
any: facial pain, pressure or loss of smell
Treatment is the same as ARS
Simple analgesia
Nasal rinses with saline
Nasal decongestants
Nasal steroids
Allergic Rhinitis
Treatments
(4)
Oral or IN antihistamines
Azelastine 1mg/ml. 1 spray into each nostril BD (only in patients 5yo and over)
or certirizine 10mg, orally, daily
IN corticosteroids (not used soley, can be used when combined with IN antihistamine)
Dymista
azelastine+fluticasone propionate 125+50 micrograms per spray, 1 spray into each nostril, twice daily
Montelukast
4-5-10mg orally daily
IN ipratropium
44 micrograms per spray, 2 sprays into each nostril, up to 3 times daily initially, reducing as rhinorrhoea improves
For conjunctivitis (allergic)
azelastine 0.05% eye drops, 1 drop into both eyes, 2 to 4 times daily
Definition of Chronic Rhinosinusitis
Symptoms lasting over 12 weeks
and consists of 2 or more of:
Facial pain or pressure
Mucopurulent discharge
Nasal blockage (congestion or obstruction)
Reduction or loss of sense of smell
Management steps for Chronic Rhinosinusitis?
(5)
- Nasal irrigation
- Similar treatments to ARS
ipratropium, IN steroids, anaglesia, NOT antihistamine, decongestants - If still persistant after 1 month consider
a. RAST testing
b. CT - If NO polyps
Refer to ENT and start on prednisolone 25 mg for 10 days
WITH polyps- refer to ENT
prednisolone 25mg daily PO for 1 week, 12.5mg daily PO for 1 week then 12.5mg alternate days PO for one more week
5- if polyps in children test for CF
If there is somehow bacterial ARS, what can you use?
Amoxicillin 1g PO, 12 hourly (500mg TDS, child 30mg/kg BD or 15mg/kg TDS) for 5 days
(follow up in 5 days)
Or
if immediate hypersensitivity;
Cefuroxime 500mg (child over 3 months 15mg/kg) PO 12 hourly for 5 days
If there is somehow bacterial ARS, what can you use?
Amoxicillin 1g PO, 12 hourly (500mg TDS, child 30mg/kg BD or 15mg/kg TDS) for 5 days
(follow up in 5 days)
Or
if immediate hypersensitivity;
Cefuroxime 500mg (child over 3 months 15mg/kg) PO 12 hourly for 5 days
What would any of these signs/symptoms indicate?
Acute onset confusion
Proptosis
Orbital swelling or oedema
Meningism- stiff neck headache photophobia
Septic shock
diplopia or impaired vision
Complicated Acute Bacterial Rhinosinusitis
If any of these features are present, hospitalisation for intravenous antibiotics and urgent surgical referral are required
What is the treatment for Acute diffuse otitis externa?
Give dosing if required
Firstly what is ADOE?
acute diffuse otitis externa is swimmer’s ear.
its is inflammation of the external ear canal usually following water exposure or ear maceration. Usually presents with ear pain, hearing loss and pruritus. The pinna can be inflammed with cellulitis and enlarged lymph nodes
treatment involves
1. dry aural toilet
2. dexamethasone+framycetin+gramicidin 0.05%+0.5%+0.005% ear drops, 3 drops instilled into the affected ear, 3 times daily for 7 days
If there is a fever, folliculitis or spread of inflammation to the pinna during acute diffuse otitis externa, what is the first line treatment?
(2)
Because of the spread to the pinna and folliculitis you have to ADD to the topical treatment:
dicloxacillin 500 mg (child: 12.5 mg/kg up to 500 mg) orally, 6-hourly for 7 to 10 days
(fluclox and cephalexin can be used at the same dosage)
PLUS
ciprofloxacin 750 mg (child: 20 mg/kg up to 750 mg) orally, 12-hourly for 7 to 10 days
How can you prevent acute diffuse otitis externa?
(4)
Again this is swimmers ear
- Wear ear plugs
- Use a shower cap in the shower
- Use a bathing cap/swimming cap in the water
- Use ear clear (acetic acid plus isopropyl alcohol ear drops, 4 to 6 drops instilled into each ear, after water exposure.)
Acute localised Otitis Externa is not the same as acute diffuse otitis externa. apparently. Though I cannot find a distinct description. Localised would indicate that it is not as bad.
However, how would you treat this?
dosing required.
dicloxacillin 500 mg (child: 12.5 mg/kg up to 500 mg) orally, 6-hourly for 5 days
or cephalexin or flucloxacillin
Pretty much as a cellulitis suspicious for staph
What should you do for any suspicious oral disease?
Referral to a specialist
Oral cancer can mimic ANY oral mucosal disease, so investigation for full biopsy by specialist is necessary.
Risk factors for oral SCC?
(9)
advanced age
male
smoking or tobacco use
alcohol use
infection by oncogenic viruses (HPV)
fx of SCC on head or neck
history of cancer therapy
prolonged immunosuppression
areca nut (betel nut ) chewing
what is this and what do you do?
This in particular is oral leukoplakia which is just a term for a non removable white lesion.
It can be homogenous like that picture or not (irregular, patchy and colour variation)
Because it can be an SCC or SCC in situ, this needs referral for biopsy
What is oral erythroplakia?
Who does if primarily affect?
and what should be done/
Erythroplakia is a clinical term for a potentially malignant fiery red lesion that cannot be attributed to any particular condition.
Urgent referral to a specialist for biopsy of oral Erythroplakia lesions is essential because approximately 70 to 90% are carcinoma in situ or squamous cell carcinoma upon presentation.
Those who are heavy smokers or abuse alcohol are most at risk.
This is?
HPV related oral lesion
Because HPV is oncogenic. Referral for biopsy and management.
What are these white striations characteristic of?
Oral lichen planus
