Vocal Cord Paralysis Diagnosis
Vocal cord paralysis is usually diagnosed by an otolaryngologist-a doctor who specializes in ear, nose, and throat disorders. Noting the symptoms the patient has experienced, the otolaryngologist will ask how and when the voice problems started in order to help determine their cause. Next, the otolaryngologist listens carefully to the patient's voice to identify breathiness or harshness. Then, using an endoscope--a tube with a light at the end--the otolaryngologist looks directly into the throat at the vocal cords. A speech-language pathologist may also use an acoustic spectrograph, an instrument that measures voice frequency and clarity, to study the patient's voice and document its strengths and weaknesses.
