(47 cards)
What is important to find out in the HPC of problems with nose?
- Nasal obstruction
- Nasal discharge
- Epistaxis
- Facial pain
- Nasal deformity
- Anosmia (reduced smell)
- Sneezing
What do you need to ask about in the PMH of someone present with nose problem?
- Medical treatment
- Nasal surgery
- Nasal trauma
- Asthma/aspirin sensitivity
What do you need to ask in the SH?
- Alcohol
- Smoking
- Cocaine abuse
What happens if olfactory epithelium of nasal lining is damaged?
Develop hyposmia (reduced smell)
What is a nasal polyp?
Prolapse of oedematous nasal lining (filled with fluid) into nasal cavity
What allergic conditions are polyps commonly associated with?
- Asthma
- Allergic rhinitis
- Aspirin intolerance
- Alcohol intolerance
What is the general cause of nasal polyps?
Chronic inflammatory process, not due to allergy
What investigations are used for high suspicion of other conditions which would change treatment?
- Blood tests: FBC, ANCA, ESR, ACE, RAST
- CT scan
- MRI scan
- Skin tests
- Rhinomanometry
What is the purpose of carrying out a CT scan?
- To identify the anatomical relationship of the key structures(optic nerve, orbital contents and carotid artery)
- Nature and extent of disease
- Anatomical abnormalities
What is rhinomanometry?
- Shows degree of nasal obstruction
* Measures air flow in each nostrils and compares with normative data to determine degree nasal obstruction
Name seven nasal disorders
- Nasal trauma
- Epistaxis
- Rhinosinusitis
- Nasal polyps
- Nasal Deformity
- Nasal tumors
- Choanal atresia
What are the two management options for nasal trauma?
- Digital manipulation - for day of or up to 7 days after (bone not fixed)
- Rhinoplasty - if longer and bones have fused the wrong way
What can nasal trauma cause?
Nasal blockage or septal haematoma
Where does cartilage relieve its blood from?
Overlying skin
What can prolonged cocaine use cause?
Septal perforation
What is aspirin hypersensitivity?
Huge inflammatory process in nose after use of aspirin which can cause polyps
What are causes of nasal polyps?
- Unknown cause
- Chronic inflammatory process
- Autonomic nervous system dysfunction
- Genetic predisposition
- Allergic vs non-allergic condition association
What non-allergic conditions are polyps commonly associated with?
- Cystic fibrosis
- Churg-Strauss syndrome
- AFS
What non-invasive investigations would be carried out to determine cause of aspirin hypersensitivity/nasal polyps?
- Sweat test (CF)
- RAST / skin testing
- Nasal smear: eosinophils (allergic component) and neutrophils (chronic sinusitis)
What invasive investigations are used for aspirin hypersensitivity/nasal polyps?
- Coronal CT scan
- MRI scan
- Flexible nasendoscopy
- Rigid nasendoscopy
What two treatments can be used for aspirin hypersensitivity/nasal polyps?
- Oral and nasal steroids - high dose prednisolone for 20 days
- Immunotherapy
How is immunotherapy used for aspirin hypersensitivity?
Tiny doeses of aspirin in ITU over 3 days and escalate to develop immune tolerance. After 3 days, patient has to take aspirin for rest of life to be desensitised to prevent allergic reaction
What three surgical treatment can be used for nasal polyps?
- Polypectomy
- Microdebrider
- Endoscopic sinus surgery
What is used to diagnose rhinosinusitis?
Sinus radiographs
