What is Local Allergic Rhinitis (LAR)?

 

 

 

Local allergic rhinitis describes a phenoytpe in which the patient has symptoms characteristic of allergies.

Symptoms usually include  nasal congestion, postnasal drainage, and excessive mucous production.  However, the patient’s allergy testing was negative. This means that the “allergen” could still be causing symptoms.  This in turn can irritate the mucous membranes of the nose and sinuses.

The diagnosis can be made, primarily in an academic center, by performing a nasal allergen provocation test. This consists of administering allergens such as local pollen directly into the nasal cavity to determine if this triggers an allergic reaction.  This test is not performed in our office.

In practical terms, this disorder is treated similar to allergic rhinitis.  Medications may be prescribed such as:

  • various nasal sprays
  • antihistamines
  • use of saline sinus irrigations
  • Allergen immunotherapy

Sometimes there are structural problems present such as enlarged turbinates. Performing a turbinate reduction procedure can be of  benefit.  This procedure can help resolve nasal congestion and obstruction symptoms.  If the condition is associated with frequent sinus infections, balloon sinus dilation of the affected sinuses may be of help.
