- allergic shiners
- nasal crease from rubbing nose
- pale or bluish boggy mucosa
- clear mucous
- polyps
- septal issues
Treatment for allergic rhinitis
- environmental control and allergen avoidance
- oral anhistamines
- leukotriene receptor antagonist
- mast cell stabilizers
- immunotherapy
Leukotriene receptor antagonists are best for what kind of rhinitis
allergic
What does nasal mucosa look like in non allergic rhinitis
normal
What does nasal mucosa look like in acute rhinosinusitis or rhinitis medicamentosa
beefy red
How is nonallergic rhinitis distinguished from allergic rhinitis
- onset at later age
- absence of nasal and ocular itching
- nasal congestion and postnasal drainage are prominent
- symptoms are perennial
Types of nonallergic rhinitis
- vasomotor rhinitis
- mixed rhinitis (most common)
- gustatory rhinitis

- acute, less than 4 weeks (bacterial or viral)
- subactue, 4 to 12 weeks
- chronic, more than 12 weeks
- recurrent, 4 or more episodes a year
Most common cause of acute rhinosinusitis
VIRAL INFECTION
- rhinovirus

- fever/fatigue
- cough
- ear pressure
- facial pain/pressure worse with bending forward
Exam finding with acute rhinosinusitis
rhinoscopy
- diffuse mucosal edema
- narrowing of middle meatus
- inferior turbinate hypertrophy
- polyps or septal deviation

- heme malignancies
- chemo induced neutropenia
- organ transplant
What differentiates bacterial rhinosinusitis from others
- facial numbness if cranial nerves involved
- necrotic tissue in nares/oropharynx
Treatment for fungal rhinosinusitis
- surgical eval for biopsy and debridement
- amphotericin B
- voriconazol
Risk factors for chronic rhinosinusitis
- allergic rhinitis
- asthma
