Certain types of injuries and conditions require specialized treatment to ensure a full recovery.

Surgical repair or other medical procedures are often necessary to restore an injured patient to their former quality of life. Our team offers comprehensive care for many types of ear, nose and throat disorders, including:

  • Allergy testing and injections
  • Excision (tissue removal)
  • Nasal endoscopy
  • Hearing exams
  • Laryngeal stroboscopy - A specialized viewing of vocal fold vibration involving controlled high-speed flashes of light timed to the frequency of your voice. Images acquired during these flashes provide a slow motion-like view of vocal fold vibration during sound production.
  • Transnasal esophagoscopy - An ultrathin, flexible scope that is introduced transnasally, allowing esophagoscopy (a digital examination) to be performed without sedation.
