Disorders of the Nose and Sinuses Flashcards
What is the function of the nose?
respiration (humidification, filtration, nasal resistance)
olfaction
Septal Hematoma:
Must remove close to prevent destruction of cartilage
Septal Perforation:
Due to trauma, digital manipulation, surgery or drugs (cocaine)
tx: saline irrigation, bactroban/vaseline
surgery for small perforations
Septal Deviation:
Can be congenital or acquired (trauma)
When is a septal deviation symptomatic?
Only symptomatic if anterior deviation
Symptoms of a septal deviation:
nasal obstruction
dryness due to airway compromise
mucus formation increased
ciliary mobility impaired
Tx of septal deviation:
septoplasty
Epistaxis:
nose bleeds; more common in cold dry environment
Mainly anterior
Kiesselbachs plexus/Littles area
Tx of Epistaxis:
vasoconstricting agent - AFRIN external pressure (10-15 min) cautery nasal packing surgery
Anosmia
complete loss of smell
Hyposmia
diminished sense of smell
Parosmia
alteration in smell such that normally pleasant odors are interpreted as foul smelling
Most common causes of olfactory disturbances:
chronic sinus disease
trauma
post viral illness
Rhinitis:
nasal hyperfunction and tissue inflammation
nasal congestion/obstruction
rhinorrhea
pruritis and/or sneezing (histamine release from mast cells and basophils)
Allergic Rhinitis:
IgE mediated response
Etiology: inhalants, foods, chemicals, pet dander
