About 10,000 new cases of throat cancer occur in the
United States per year, affecting mainly older males who have
been heavy smokers or alcohol abusers. The incidence of throat cancer in women and young
people has increased as these groups have been using cigarettes
and alcohol in greater numbers.
Total laryngectomy is the
most common form of surgery for cancer of the larynx. It requires
complete removal of the voicebox and the creation of a permanent
breathing opening in the neck (tracheostoma). If part of the
pharyngeal wall is involved, part or all of the pharynx will
usually have to be removed usually with the larynx. If a large
amount of tissue is removed, additional skin from other parts of
the body (flap) will be used for reconstruction. People are
usually able to swallow reasonably normally after total
laryngectomy, but will not be able to breathe through their mouth
or nose and will not be able to talk.
Spoken communication may
be restored with mechanical generation of sound with an
electrolarynx enabling the patient to mouth words while vibrating
their neck and throat. Another more easily understood
method of talking is esophageal speech. Air
is injected into the esophagus, and reversed back up to produce
sound for speech. This is often difficult to master.
A popular method of speech production following
laryngectomy is the voice
restoration procedure developed by Drs. Eric Blom and Mark Singer. A puncture is
placed through the back wall of the trachea windpipe (trachea)
into the esophagus and held open with a one-way valved
prosthesis. By occluding the opening in the neck (tracheostoma),
air is directed through the voice prosthesis into the throat
causing vibration of the soft tissue and generating voice. Fluent
speech that is usually readily understandable is produced.Top | Head and Neck Surgery | Voice
