Allergic Rhinitis

Anterior rhinoscopy showing an obviously hypertrophied and pale

inferior turbinates (arrows).

[V - vestibule (hair bearing area between the nasal introitus to mucocutaneous junction), C - columella]

Swollen inferior turbinate with excess

mucous production and reduced nasal patency.

Nasal endoscopy appearance of untreated severe allergic rhinitis.


Symptoms of allergic rhinitis include rhinorrhea, nasal obstruction,

nasal itchiness, and recurrent bouts of sneezing.  It can occur intermittently

or persistently with its severity varies from mild to moderate-severe.

Tail of inferior turbinate hypertrophy (T) in a patient with allergic rhinitis made visible by nasal endoscopy. 

[IT - inferior turbinate, V - vomer, N - nasopharyx, R - roof of nasopharynx]

Allergic Rhinoconjunctivitis

              Allergic conjunctivitis                           No allergic conjunctivitis


Conjunctival irritations, watery eyes, suffusion, and increased vascular

patterns, are amongst its prominent clinical manifestations.  These occur

in association with allergic rhinitis which need to be treated as well. 

Allergic shiner's (lower eyelid oedema) is common.

Conjunctival smear or brushing reveals eosinophils.

Inferior Turbinate Submucosal Hyperaemia/Patechiae

Submucosal petechial lesion of inferior turbinate head (+) complicating hard pinching of nasal alar and nasolabial fold in attempt to stop intense itchiness and to prevent sneezing in allergic rhinitis.  [V - nasal vestibular skin, S - nasal septum]

Right Little's area hyperaemia and patechiae occurring in a patient with pronounce nasal itchiness and severe bouts of sneezings.

Allergic Skin Test

The common groups of allergen tested includes house dust mites,

fungi, epidermals and insects, grass and pollens. 


 The array of allergens used for skin prick test.


Positive test is conluded when there is erythema of at least 3 mm diameter, with or without the presence of wheal. 


Patterson’s system for scoring skin tests (wheals diameter grade):                         

        0   : no reaction

        1+ : < 4mm

        2+ : 5 - 10 mm

        3+ : 10 - 15 mm

        4+ : > 15 mm


Sensitization should be considered when the allergen extract's diameter:

i. superior to negative control (saline) wheal diameter by at least 3 mm; and

ii. at least equal to half the positive control (histamine) wheal diameter.

(Positive control- histamine; negative control- saline)
