- Chronic simple laryngitis:
Episodic hoarseness which is most prevalent upon arising in the morning
As the physical activity increases the sound improves
The next morning the hoarseness returns
Over long periods of time there is fatigue of the voice and sound cannot be emitted for an extended period
Throat discomfort and pain upon emitting sounds
There is often a habit of clearing ones throat but no evident sputum is coughed up
The hoarseness is more evident when attempting to make a high pitched sound
Diffuse hyperemia of the laryngeal mucosa
The vocal cords have lost their original pearl white color and turned pink or progressed to a deeper red
The vertical capillaries running parallel to the border of the vocal cords are enlarged
The border is thickened
The glottis cannot be closed completely, or
The bilateral vibration is not balanced
The exterior of the vocal cords are often covered by a sticky secretion which forms sticky silk - like strands connecting the interglottic space
- Chronic hypertrophic laryngitis:
Episodic hoarseness which is most prevalent upon arising in the morning
As the physical activity increases the sound improves
The next morning the hoarseness returns
Over long periods of time there is fatigue of the voice and sound cannot be emitted for an extended period

- Throat discomfort and pain upon emitting sounds
There is often a habit of clearing ones throat but no evident sputum is coughed up
The hoarseness is more evident when attempting to make a high pitched sound
A long history of hoarseness and aphonia
Hoarseness is very evident
Coughing is relatively mild
Occasionally there are acute flare ups causing a further increase in hoarseness and deterioration in the sound quality
Symmetrical swelling of the laryngeal mucosa is observed but the distribution is not even and is more marked in the arythenoid space where it stands out high
When a sound is emitted it forms one or several plica in the arythenoid space
The vocal cord is thickened, appearing like a stick that is rough and not smooth and often takes on a nodular or polypoid form which is covered by a sticky secretion
If the disease progresses to the areas below the glottis, it prevents the vocal cords from uniting and triangular fissures appear
If the disease progresses to the areas below the glottis, it prevents the vocal cords from uniting and triangular fissures appear
The ventricular folds are enlarged and often press on the vocal folds when a sound is emitted
The aryepiglottic fold may also be thickened but enlargement of the epiglottis is extremely rare
