Glossary
Note: Within a definition, words in italics are defined elsewhere in the glossary. Words beginning with * were coined or brought into the language of voice disorders by Dr. Bastian, or to our knowledge are used primarily by BVI physicians and Bastian-trained fellows. Please note that we may be adding terms to this list from time to time. Copyright © 2008 Bastian Voice Institute.
Obligatory falsetto:
A part of the phenomenology often seen with vocal fold paralysis,
or in the early days to weeks following a laryngeal Botox™
injection. Regardless of effort or skill level, the individual
cannot get the voice to phonate in other than falsetto register;
hence, “obligatory falsetto.”
“Objective”
measures of phonatory function: This terminology
is used widely to refer to machine-made measures of acoustic,
aerodynamic, and
electroglottographic output
of the voice. At BVI we use quotes around the term objective
because, for several basic reasons, these measures are not
as objective as they are given credit for. First, the result
of such measures may vary markedly with seemingly small changes
in voice production, within the same voice. Second, the measures
may be entirely non-specific to any particular diagnosis or
condition. In other words, one might have the same or highly
similar jitter, shimmer,
and aerodynamic
measures for any one of several completely different diagnoses,
e.g., vocal fold cancer, vocal
fold paralysis, vocal fold
bowing, nonorganic voice disorder,
and so forth.
Olympic button:
A self-retaining “mini-trach”
device that requires no ties or dressings, used in individuals
who are not technically tracheotomy-dependent
but who may need a “back door” to breathe through
on an intermittent basis. Examples include individuals with
marginal airways who are functional with plugged Olympic button
through the day but whose airway further collapses during
sleep at night. In such a case, the plug is removed from the
Olympic button only at night.
*Onset delay: The phenomenon
of slight delay from the moment of intended phonation until
sound actually commences. Often there is a faint hiss of air
heard before the start of vocal fold vibration.
Otolaryngologist:
Short form for otorhinolaryngologist, and the official name
of an ear, nose, and throat physician.
Outpatient surgery: Surgery
done in a day surgery center, or in the day surgery section
of a hospital where the patient is not expected to stay overnight.
Most often, the patient reports early the morning of surgery
for admission to the hospital, has the procedure done, and
then departs from recovery room to home.
