Objective measures of phonatory function

This terminology is used widely to refer to machine-made measures of acousticaerodynamic, and electroglottographic output of the voice. At our practice 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 jittershimmer, and aerodynamic measures for any one of several completely different diagnoses, e.g., vocal cord cancer, vocal cord paralysis, vocal cord bowing, nonorganic voice disorder, and so forth.



Obligatory falsetto

Obligatory falsetto is part of the phenomenology often seen with vocal cord 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.”




Olympic button

The olympic button is 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

Onset delay is 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 cord vibration.




Open Epidermoid Cyst

An open epidermoid cyst occurs when it spontaneously ruptures, but yet not empty all of its contents (keratin). The outline of the partially-emptied cyst may still be very evident, but it usually assumes an oval shape with the long axis oriented anteriorly and posteriorly. If the cyst empties nearly completely, the white oval is no longer seen, but the vocal cord may have a mottled appearance. If the cyst empties completely, a sulcus lined by epithelium remains.

Otolaryngologist

Short form for otorhinolaryngologist, an otolaryngologist is the official name of an ear, nose, and throat (ENT) physician.



Outpatient surgery

Outpatient surgery is surgery done in a day 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.
