·  In the GRBAS Scales, four grades of scale are recommended because of their high reproduction rate and sufficient resolution

·  Using the VHI and V-RQOL as patient-reported outcome measures They  are,  strongly recommended  as  subjective  evaluation  tools  for  voice  disorders as they are highly  reliable  and  validated

·  Laryngoscopy is an essential tool for visualization of the larynx to diagnose the cause of dysphonia

·  Laryngostroboscopy is useful for diagnosis of voice disorders. It is also useful for the diagnosis and monitoring. Laryngostroboscopy was useful for the diagnosis of patients with voice disorders in 27.2% of cases

·  Acoustic analysis is useful in objective evaluation of voice disorders, especially for evaluating effectiveness of treatment. 

·  measurement  of  voice  strength, measurement  of  pitch,  measurement  of  expiratory  flow  in phonation, measurement  of  MPT,  measured  individually  or combined

·  clinicians should advocate voice therapy for patients with dysphonia from a cause amenable to voice therapy

·  Clinicians should inform patients with dysphonia about control/preventive measures

·  Clinicians should document resolution, improvement, or worsened symptoms of dysphonia or change in QOL among patients with dysphonia after treatment or observation.

➡️Purpose

Appraisal of the research evidence that exists to support the use of voice measures in the clinical assessment of patients with voice disorders. And outline the measures used in the management of Functional voice disorders.

Specifically,  the  goals  are  to  improve  diagnostic  accuracy,  identify  cases  who  are  most  susceptible  to  voice disorders,  and  educate  clinicians  and  patients  regarding  voice disorders   

➡️The target audience    

The guideline is intended for all clinicians who are likely to diagnose and manage voice disorders
