Information for Patients

Throat Disorders

Also called: Pharyngeal disorders

Your throat is a tube that carries food to your esophagus and air to your windpipe and larynx. The technical name for throat is pharynx.

Throat problems are common. You've probably had a sore throat. The cause is usually a viral infection, but other causes include allergies, infection with strep bacteria or the upward movement of stomach acids into the esophagus, called GERD.

Other problems that affect the throat include

  • Tonsillitis - an infection in the tonsils
  • Pharyngitis - inflammation of the pharynx
  • Cancers
  • Croup - inflammation, usually in small children, which causes a barking cough

Most throat problems are minor and go away on their own. Treatments, when needed, depend on the problem.

  • Acute upper airway obstruction
  • Epiglottitis
  • Glossopharyngeal neuralgia
  • Herpangina
  • Laryngitis
  • Laryngoscopy
  • Retropharyngeal abscess
  • Strep throat
  • Throat swab culture

Tracheal Disorders

Also called: Windpipe disorders

Your trachea, or windpipe, is one part of your airway system. Airways are pipes that carry oxygen-rich air to your lungs. They also carry carbon dioxide, a waste gas, out of your lungs.

When you inhale, air travels from your nose, through your larynx, and down your windpipe. The windpipe splits into two bronchi that enter your lungs.

Problems with the trachea include narrowing, inflammation, and some inherited conditions. You may need a procedure called a tracheostomy to help you breathe if you have swallowing problems, or have conditions that affect coughing or block your airways. You might also need a tracheostomy if you are in critical care and need to be on a breathing machine.

Voice Disorders

Also called: Vocal disorders

Voice is the sound made by air passing from your lungs through your larynx, or voice box. In your larynx are your vocal cords, two bands of muscle that vibrate to make sound. For most of us, our voices play a big part in who we are, what we do, and how we communicate. Like fingerprints, each person's voice is unique.

Many things we do can injure our vocal cords. Talking too much, screaming, constantly clearing your throat, or smoking can make you hoarse. They can also lead to problems such as nodules, polyps, and sores on the vocal cords. Other causes of voice disorders include infections, upward movement of stomach acids into the throat, growths due to a virus, cancer, and diseases that paralyze the vocal cords.

Signs that your voice isn't healthy include

  • Your voice has become hoarse or raspy
  • You've lost the ability to hit some high notes when singing
  • Your voice suddenly sounds deeper
  • Your throat often feels raw, achy, or strained
  • It's become an effort to talk

Treatment for voice disorders varies depending on the cause. Most voice problems can be successfully treated when diagnosed early.
