DRAFT SECTION: I've been editing this section to try and make it applicable to all the types of laryngitis. It is most straight-forward here to use bulleted lists, but I've tried to separate general signs from those visible with stroboscopy/laryngoscopy. I have a note below on a paragraph I've left out from the original article!
---------
I'll first of all be adding in the IPA for the Lead section (someone else is editing the rest of the lead section!):
Signs and symptoms
editThe primary symptom of laryngitis is hoarseness of voice. Because laryngitis can have various causes, other signs and symptoms may vary[1]. They may generally include:
- Dry or sore throat
- Coughing (both a causal factor and a symptom of laryngitis)
- Frequent throat clearing
- Increased saliva production
- Dysphagia (difficulty swallowing)
- Sensation of swelling in the area of the larynx (discomfort in the front of the neck)
- Globus pharyngeus (feeling like there is a lump in the throat)
- Cold or flu-like symptoms (which, like a cough, may also be a causal factor for laryngitis)
- Swollen lymph nodes in the throat, chest, or face
- Fever
- General muscle pain (myalgia)
- Shortness of breath, predominantly in children
Physical Characteristics
editThe larynx itself will often show erythema (reddening) and edema (swelling). This can be seen with laryngoscopy or stroboscopy (method depends on the type of laryngitis)[2]. Other features of the laryngeal tissues may include:
- Redness of the laryngeal tissues (acute)
- Dilated blood vessels (acute)
- Thick, yet dry laryngal tissue (chronic)
- Stiff vocal folds
- Sticky secretions between the vocal folds and nearby structures (the interarytenoid region)
Voice Quality
editAside from a hoarse-sounding voice, changes to pitch and volume may occur with laryngitis. Speakers may experience a lower or higher pitch than normal, depending on whether their vocal folds are swollen or stiff[1][3]. They may also have breathier voices, as more air flows through the space between the vocal folds (the glottis), quieter volume[4] and/or a reduced range[1][2].
Early Referral Signs
editSome signs and symptoms indicate the need for early referral[5]. These include:
- Dysphagia (difficulty swallowing)
- Vocal stridor
- Ear pain (otalgia)
- Recent weight loss
- History of smoking
- Current or recent radiotherapy treatment (in the neck region)
- Recent neck surgery or surgery involving endotracheal tubing
- If the client is a professional voice user (teacher, singer, actor and so on)

THIS WAS ORIGINALLY IN THE ARTICLE. I haven't found any sources for this, so I'm not entirely sure what to do with it. I tried to generally add in the information, but it is also SO technical. Peer reviewers, I'd love your thoughts! - JR-
- edit: I'm leaving most of this out. I have added in the part about sticky secretions, but am having a hard time finding a reference from the previous author of this section.
In early stages, erythema (reddening) and edema (swelling) of the epiglottis, aryepiglottic folds, arytenoids and ventricular folds occur. In late stages, the vocal folds and subglottic structures are also involved. There are sticky secretions between folds and in the interarytenoid region. Sometimes, submucosal hemorrhage is seen, especially in cases of vocal abuse. Acute membranous laryngitis, a condition resembling acute membranous tonsillitis, is caused by pyogenic nonspecific organisms. It has to be differentiated from laryngeal diphtheria. In some cases, tightening of the chest may be present due to COPD or other relevant breathing disorders.

PREVIOUS THOUGHTS
-- thoughts -- reorganize into throat/person attributes/characteristics (collapse surgeries etc)
-cite wood article and also the schwartz et al article (clinical practice guideline: hoarseness (dysphonia), 2009)
NEW INFORMATION: in bold.
-notes: edit "non-specific"? make it clearer that non-specific means that these signs and symptoms can accompany numerous different voice disorders (?)
Plans for editing the Laryngitis article:
-Thoroughly check sources in the Signs & Symptoms section - expand (try looking at "hoarseness" for more
- add in the IPA for pronunciation : Help:IPA and Help:IPA for English
-Check out the following sources for citations:
