| For
patients requiring a laryngectomy, the prospect of
losing the voice may be the most disturbing element
of the operation. The patient often fears the psychological,
social and economic impact upon himself or herself
and family. Rapid, effective rehabilitation, particularly
of speech, can greatly lessen this impact by restoring
the patient to his or her full capacity. A laryngectomy
is the surgical removal of the larynx. The larynx,
also called the voice box, is the organ in the throat
that creates speech and, in conjunction with the epiglottis,
prevents food from entering the airway during swallowing.
It lies between the trachea (windpipe) and the upper
part of the airway known as the pharynx, forming part
of the tube in the throat that carries air to and
from the lungs to create speech, air from the lungs
is expelled over the vocal cords in the larynx, resulting
in vibrations, which are modified by the tongue, palate
and lips. When the larynx is removed, the top of the
trachea immediately below the larynx is attached to
a permanent opening made in the throat called a stoma.
It is through this opening that the laryngectomee
breathes.
Understanding
Voice Restoration
With persistence, a laryngectomee can learn from a speech pathologist
new ways of speaking. One option, called Esophageal Speech, involves
the patient learning to breathe in a manner that injects air into
the pharynx, expelling it in a controlled way to form voicing. Another
option, known as an Artificial Larynx, uses a speaking aid device
that emits a vibrating noise and is held against the throat. By mouthing
words, a laryngectomee converts the vibrations into speech. A third
option, called Tracheoesophageal Puncture (TEP), is described below.

Prostheses and
Tracheoesophageal
Puncture (TEP)
Today, advances in medical technology enable speech production by
means of voice prosthesis. By creating a small surgical passage (TEP)
just inside the stoma, from the back wall of the trachea into the
esophageal wall, a small one-inch valved tube (voice prosthesis) can
be placed into this passage to enable tracheoesophageal speech. Voice
is produced by temporarily blocking the stoma, either with a finger
or an adjustable tracheostoma valve, so that exhaled air from the
lungs can be directed from the trachea through the prosthesis into
the esophagus (where vibrations are produced) and then out through
the mouth. Fluent, conversational speech may be acquired within a
few days. Blom-Singer voice prostheses have set the standard in post-laryngectomy
voice restoration since 1979. Drs. Blom and Singer continue to introduce
innovative procedures and medical devices allowing thousands of patients
worldwide to regain their ability to speak.
