Ear, nose & throat

Ear, Nose and Throat (Otolaryngology) concentrates on both surgical and non-surgical treatment of a wide variety of head and neck disorders in adults and children. Otolaryngologist, Jason Showmaker, MD, has clinical interests including pediatric otolaryngology, allergy and sinonasal disorders, and thyroid and parathyroid surgery.


Capital Region Physicians – ENT & Audiology offers comprehensive diagnoses and treatment of nasal and sinus disorders.

Nasal conditions can stem from something temporary, like a cold, or something longer-lasting, like a deviated septum. Identifying the root cause allows our team to fix or remove it and lower the chance of future blockages. 

Nasal disorders include obstructive sleep disorders, deviated septum, turbinate hypertrophy, external nasal deformity and adenoid hypertrophy. 


The sinuses connect to the nasal cavity by small drainage pathways. Abnormal structure, acute or chronic infections, or allergies may cause swelling of the nasal lining, which can lead to obstruction of the flow of drainage. This can set the stage for an infection within the sinuses.

Factors that can contribute to sinusitis include:

  • Frequent upper respiratory infections
  • Smoking
  • Allergies
  • Gastric Reflux
  • Cystic fibrosis
  • Immune deficiencies
  • Structural defects of the nasal bones


Dr. Jason Showmaker offers a comprehensive, multidisciplinary approach to managing allergies and allergic disorders, including: 

  • Inhalant allergies(dust, molds, pollen, animals, weeds, trees, etc.)
  • Skin allergies
  • Asthma and reactive airway problems
  • Food allergies

Allergy Testing

There are many ways to test you to see if your symptoms may be caused by allergies. There are three types of allergy skin testing that are done to help your doctor identify what may be causing your allergy symptoms.

  • Skin Prick Testing
  • Intradermal Testing
  • Patch Testing

Capital Region Physicians – ENT & Audiology offers allergy testing on children three years of age and older.
