O-TO-LAR-YN-WHAT? Otolaryngology (pronounced oh/toe/lair/in/goll/oh/jee) is the oldest medical specialty in the United States. Otolaryngologists are commonly referred to as ENT physicians. And, at Catalyst Medical Center we have two of them. ENT physicians treat ailments such as ear and sinus infections, chronic sore throats, allergies, sleep apnea and more. February is Kids ENT Health Month.
