➡️Glossary:

Dysphonia:  Altered vocal quality, pitch, loudness, or vocal effort that impairs communication as assessed by a clinician and/or affects quality of life

Patient-reported  outcome  measures: subjective  evaluation  by patients  with  voice  disorders,  the  Voice  Handicap  Index  (VHI) and  Voice-Related  Quality  of  Life  (V-RQOL)  were  developed  from  the  viewpoint  of  the  disorders’  effects  on patient  quality  of  life. 

Stroboscope: Advanced laryngeal imaging designed to visualize vocal fold vibratory abnormalities that cannot be appreciated with continuous light laryngoscopy. It uses a synchronized flashing light that passes through a laryngoscope

The aerodynamic  assessment  :  is  defined  as  “individual  or  combined  measurements  of  voice  strength,  pitch, expiratory  flow  in  phonation  and  maximum  phonation  time (MPT)” .  This  method  enables  examiners  to  understand  the pathological  conditions  related  to  vocal-fold  vibration,  and  it  is useful  to  compare  the  patient’s  voice  before  and  after  treatment

Acoustic  analysis  is  an  objective  evaluation  of  voice disorders  that  analyzes  speech  signals  and  provides  quantitative evaluations.

Voice therapy: is provided for dysphonia with no morphological abnormality.  Voice  therapy  is  also  applicable  to  motor diseases,  such  as  vocal-fold  paralysis,  Parkinson’s  disease,  or psychogenic  vocal  disorders.  Voice  therapy  has  a  long  history both  in  direct  and  indirect  therapy,  and  methodologies  of  the therapies  based  on  various  theoretical  systems  have  been developed,  but  its  classification  or  application  has  not  been established  adequately

➡️Scope

This Guideline is concerned with diagnosis and treatment decision of voice disorders affecting children and adults
