special senses Flashcards
symptoms/signs of otitis external
- pain: sharp, starts in tracus, radiates to pinna
- discharge: thick and scanty
- irritation and itching
- swelling
- pre auricular enlarged nodes
- impaired hearing if meatus is blocked
treatment of otitis externa
- systemic analgesia+ hot pad
- ear drops (aluminium acetate, topical antibiotics + steroids)
- systemic antibiotics (if fever or lymphadenitis)
- pope wick if meatus swelling
- gentle micro suction of the ear (to remove debris)
complications of otitis external
- facial cellulitis
- otomycosis
- osteomyelitis/malignant otitis externa
- pericondritis
- canal stenosis with hearing loss
risk factors in developing otitis external
skin conditions
instrumentation in ear canal
swimmers ear
pathogens responsible for otitis externa
staph aureus aspergillus niger (fungal) pseudomonas aeriguinosa
pathophysiology of glue ear/otitis media with effusion
blocked/narrowed eustachian tube: fluid build up in middle ear
no infection
symptoms of acute otitis media
- deep seated pain
- impaired hearing
- systemic illness with fear
- blocked feeling in the ear
- discharge (if perforation)
- child tugs ear
pathogens involved in otitis media
streptococcus pneumoniae
haemophilia influenzae
diagnosis of acute otitis media
inspect tympanic membrane
conductive hearing loss
treatment of acute otitis media
- usually self limiting
- pain relief with analgesia and hot pad
- systemic antibiotics (ie amoxycillin)
- antibiotic drops if perforation
- if bulging ear drug: myringotomy
- if perforation: myringoplasty
- grommets (if recurrence)
complications of acute otitis media
- mastoiditis
- cholesteatoma
- recurrent acute otitis media (4+ episodes in 6 months)
- chronic suppurative otitis media (> 3m)
- hearing loss
- facial palsy
- suppurative labyrinthitis
- meningitis
- extradural/subdural/brain abscess
cause of nasal obstruction
- polyps
- malignant tumours
- septal deviation
- foreign body
- rhinosinusistis
when do you realign nose in trauma
- immediately
- 5-14 days post trauma (with surgery)
red flags nose
- unilateral nasal polyps
- persistent nose bleeds
- persistent glue ear
- unilateral congestion
causes of septal deviation
- Gradulomatosis polyangitis arteritis
- sarcoidosis
- infective septal haematoma
- trauma
- congenital
management of septal deviation
septoplasty
pathogens in rhino sinusitis
- rhinovirus
- influenza virus
- parainfluenza virus
- streptococcus pneumoniae
- haemophilus influenza
- staphylococcus aureus
- moraxella catarrhalis
diagnosis acute rhinosinusitis
- up to 4 weeks
- purulent nasal drainage and nasal obstruction
- facial pain pressure
diagnosis of chronic rhino sinusitis
- 12 weeks of
nasal obstruction, drainage, facial pain and decreases sense of smell
- 12 weeks of
AND one of the following
- inflammation in sinuses (seen on imaging), purulent mucus, polyps in middle meatus
management of rhino sinusitis
- saline nasal irrigation
- topical nasal steroids 6 weeks
- decongestants ‘max 10 days
- antihistamines (if allergies)
- sinus surgery (if does not respond to medical treatment)
- for polyps: prednisolone + above
complications of sinusitis
brain abscess
orbital cellulitis
epistaxis types
90% anterior (Little’s area)
10% posterior (Woodruf’s plexus)
risk factors in developing epistaxis
- trauma
- hypertension
- bleeding disorder
- rhinitis
- recent nasal surgery
- carcinoma
- recreational drugs
management of epistaxis
- press cartilaginous part of the nose and head forwards for 15 min
- nasal cautery w/ silver nitrate (one side only)
- naseptin ointment (prescribe 1-2 weeks to keep nasal cavity free of crusts)
- nasal packing (anterior, posterior packs and Foley catheter): must admitt for 24h + do bloods (FBC, G&S, coag profile)
- surgery
red flags neck lumps
persistent sore throat hoarseness dysphagia odynophagia weight loss fevers night sweat
differentials of midline lumps
dermoid cysts
thyroglossal cysts
thyroid lump
reactive lymphadenopathy
differentials for lateral neck lumps
reactive lymphadenopathy branchial cyst thyroid mass cystic hygroma cervical rib lipoma
lymphadenitis presentation
- painful
- associated illness
dermoid cysts presentation
- midline
- moves with skin
thyroglossal cyst presentation
- unlikely painful
- midline
- moves with swallowing
- moves on protruding tongue
branchial cyst presentation
- possible painful
- anterior to sternocleidomastoid (left side)
- late childhood/early adulthood
- slowly enlarging
- may enlarge after RTI
- male
- smooth, soft, fluctuant
goitre/thyroid mass presentation
- possible painful
- associated symptoms (hypo/hyperthyroid)
- moves with swallowing
thyroid mass differentials
- follicular adenoma
- hyperplastic nodules
- thyroid cysts
- carcinoma
red flag thyroid mass
- stridor
- unexplained hoarseness
- thyroid nodule in a child
- rapidly enlarging painless thyroid mass

risk factors for head and neck cancer
alcohol
smoking
HPV
betel nut chewing
investigations head an neck cancer
panendoscopy and biopsy
CT skull base to diaphragm
causes of swollen optic disc
- raised intracranial pressure
- space occupying lesion
- optic neuritis

- central retinal vein occlusion
symptoms of cataracts
- painless gradual loss of vision
- glare (struggle with night vision)
- halos around lights
