Q

how does auditory signal pass from the cochlea to the auditory cortex

A

The auditory signal passes along the cochlear nerve to the cochlear nucleus in the brainstem
Most then crosses to the contralateral side
The signal then passes up the brainstem through the superior olivary nucleus and then the lateral lemniscus in the midbrain to the inferior colliculus
Then passes through the medial geniculate body to the auditory cortex

26
Treatment of chronic otitis media
Micro suck and inspection of the ear under microscope Topical antibiotic and steroid drops for 7-10 days if active infection Strict water precautions If medical strategies not effective or the ear discharge is particularly affecting pts life then myringoplasty can be performed - surgical repair of the ear drum
27
Presentation of chronic otitis media
inflammatory condition affecting the middle ear for a period greater than 3 months. Active or inactive and 2 types, mucosal and squamous epithelial COM. Active mucosal disease - perforated tympanic membrane allows infection to develop in the middle ear Active squamous epithelial disease results from cholesteatoma formation Inactive mucosal disease -dry perforation Inactive squamous epithelial -shallow self cleaning retracted tympanic membrane. can present with Recurrent intermittent discharge arising from ear hearing loss may be present mucosal usually to do with pars tensa squamous usually pars flaccida
28
What is a cholesteatoma Symptoms Complications
Deep retraction of the tympanic membrane that has keratin accumulated in it and can develop into a keratin cyst Usually forms due to chronic Eustachian tube dysfunction Discharge from the can be offensive Hearing loss Doesnt respond to antibiotic drops or oral antibiotics Imbalance The keratin cyst can expand and erode the ossicles and eventually damage structures adjacent to the middle ear
29
What is a glomus jugulare
Vascular tumour that presents as a red mass behind an intact tympanic membrane Patient may have pulsatile tinnitus
30
initial management of cholesteatoma
topical abx and steroid drops if infection present pure tone audiogram to determine degree of hearing loss close inspection and cleaning of the ear under the microscope
31
definitive surgical management of cholesteatoma
mastoidectomy - opening the mastoid air cells, removing the cholesteatoma from the middle ear followed by reconstructing of the ossicles and tympanic membrane CT guided
32
complications of middle ear surgery (for chronic otitis media or other conditions)
Infection Bleeding No improvement in hearing Complete loss of hearing, called a dead ear (if the inner ear is damaged) Tinnitus Vertigo Facial nerve injury, resulting in facial palsy Altered taste (chorda tympani nerve damage) Recurrence of disease needing revision surgery
33
Otitis media with effusion
inflammatory condition of the middle ear in which there is development of a middle ear effusion. This causes a conductive hearing loss. It is not an infection although it may follow an infection.
34
where in the tympanic membrane do - retractions tend to occur - perforations tend to occur
retraction - pars flaccida (attic) perforations - pars tensa
35
intratemporal complications of Chronic Otitis Media
Vertigo - inflammation spread to labyrinth Hearing loss - conductive or SN Acute otitis externa Facial weakness - facial nerve involvement

67
what constitutes acute or chronic rhinosinusitis
Acute rhinosinusitis (ARS) lasts less than 12 weeks with complete resolution of symptoms. Chronic rhinosinusitis (CRS) lasts more than 12 weeks without complete resolution of symptoms.
68
key points of nasal examination
external inspection anterior nose - Thuddicums speculum posterior nose - flexible nasal endoscope
69
where is the most common side of epistaxis
Littles area/ Kiesselbach's plexus - formed by 3 arteries; anterior ethmoid artery, the sphenopalatine artery and the greater palatine artery
70
silver nitrate cautery
if a prominent vessel identified as the source of epistaxis can only be done to one side of septum cauterised holding the silver nitrate stick in each position for 15 seconds. The vessel itself can then be cauterised. Antiseptic cream, such as Naspetin, should then be applied and given to the patient to apply twice daily for 2 weeks.
71
advice to patients to reduce occurrence of epistaxis
for a few weeks; avoid hot drinks avoid very hot baths/showers avoid picking the nose avoid very hot and spicy foods if recurrence; apply pressure for 15 mins and if this fails attend A&E
72
management of epistaxis that doesn't stop with pressure
A-E check airway and breathing circulation; IV access, haemodynamically stable? FBC, coag profile, group and save apply pressure if identifiable cauterise source of bleeding continued bleeding? anterior nasal packing continued bleeding? posterior nasal packing continued bleeding? ligate artery in surgery
73
factors that contribute to development of epistaxis in adults
-most common cause is trauma i.e. punching -pmhx of hypertension, anticoagulant or antiplatelet therapy - inflammation of the nasal mucosa - rarely malignancy
74
what nasal malignancy is most common
squamous cell carcinoma most commonly occurs in individuals of Chinese origin
75
most common cause of epistaxis in children
mainly due to bleeding from Little's area primarily due to trauma in most cases stops with pressure and can be prevented from bleeding recurring using cream such as naspetin or bactroban
76
what is tranexamic acid when is its use contraindicated
used for epistaxis sometimes anti fibrinolytic agent. contraindicated - blood clots, bleeding in the brain, or urine, heart valve problems, visual problems secondary to bleeding, irregular heartbeat, irregular unexplained menstrual bleeds, using birth control medication or devices, taking medication such as clotting factors and medication containing tretinoin
