grommet insertion - to allow air to pass through into the middle ear and hence do the job normally done by the Eustachian tube. The majority stop functioning after about 10 months
adenoidectomy
93
in Ramsey Hunt syndrome, where does VZV reactivate
geniculate ganglion of the seventh cranial nerve
94
what is exostosis of the ear
Exostosis is where bone grows abnormally in the ear due to repeated exposure to cold water. It affects people who swim or surf a lot in cold water – that's why it's sometimes called surfer's ear.
95
which part of the nose is epistaxis most likely to come from?
Little's area in the anterior nasal septum is the site of Kiesselbach's plexus, supplied by 4 arteries
96
which infection is tonsils SCC associated with
HPV-16
97
why should ntranasal decongestants (e.g. oxymetazoline) not be used for prolonged periods
increasing doses are required to achieve the same effect (tachyphylaxis) and rebound hypertrophy of the nasal mucosa (rhinitis medicamentosa) may occur upon withdrawal

102
normal threshold on audiogram
20db
in sensorineural hearing loss both air and bone conduction are impaired

treatment of quinsy
need urgent review by an ENT specialist.
needle aspiration or incision & drainage + intravenous antibiotics
tonsillectomy should be considered to prevent recurrence in 6 weeks
107
management of acute sinusitis

intranasal decongestants or nasal saline may be considered but the evidence supporting these is limited
NICE CKS recommend that intranasal corticosteroids may be considered if the symptoms have been present for more than 10 days

The BNF recommends phenoxymethylpenicillin first-line, co-amoxiclav if 'systemically very unwell, signs and symptoms of a more serious illness, or at high-risk of complications'
'double-sickening' may sometimes be seen, where an initial viral sinusitis worsens due to secondary bacterial infection
