Allergy Department

Collin County Ear Nose and Throat aims to offer the full spectrum of treatment for patients with sinus and allergy problems, not just medication or surgical procedures.  

All physicians are board certified in otolaryngic allergy, and the physicians, nurse practitioner, and allergy nurses have all taken additional educational courses to augment their knowledge.  Some are members of the American Academy of Otolaryngic Allergy.  The allergy department has been a vital part of our practice for over 25 years.  While our allergy nurses have extensive experience, the department works very closely with the physicians to customize the treatment for each patient.

To identify what environmental substances to which a patient is allergic, one of two testing methods are employed.  Patients undergo either a technique called Intradermal Skin Testing (Skin Endpoint Titration, or SET) or a blood test called RAST (Radioallergosorbant Test) for 32 inhalants that are native to the North Texas area.  Examples of these inhalants include grasses, weeds, trees, cat and dog dander, molds, and dust mites.

Patients may then be treated simply by receiving education about avoidance of their allergens, seasonal medication therapy, or immunotherapy.  Immunotherapy is a way to build up “tolerance” to those environmental substances to which a patient is allergic.  This is accomplished by either periodic injections (“allergy shots”) or Sublingual Immunotherapy (SLIT), both of which we offer.

 Much of the testing and treatment of allergy is covered by your insurance.  The sublingual therapy currently is not covered.  The hours of testing and treatment are conducive to most schedules, with both early and late hours.  Please contact us if you have any further questions or would like to schedule an evaluation.
