2. Dysphonia - voice disorder characterized by
altered vocal quality, pitch, loudness, or vocal effort
that impairs communication or reduces voice-related
quality of life.
Hoarseness affects nearly 1/3 of the
population at some point in their lives.
Seth R. Schwartz et al, Clinical practice guideline: Hoarseness (Dysphonia)
Otolaryngology–Head and Neck Surgery, Vol 141, No 3S2, September 2009

3. Aim
Evaluate the effectiveness of voice therapy in patients,
who used only this method for dysphonia treatment in
Pauls Stradins Clinical University Hospital in year 2015

4. 5 patients with different diagnosis were observed
 1st therapeutic course
 4 females, 1 male
 Non-smokers
 4 – 6 workshops

5. Patient evaluation

11. Results
 Objective parameters have improved in all patients
 Most difficult vowel is [a - latvian]
 MPT was normal in 3 patients
4 patients raised VHI score by self-assessment
 Different value of GRBAS score of patient and
researcher

12. Conclusions
 Voice therapy could be effective also as a single
therapeutic method
 Objective and subjective values demonstrate
improvement
 It is reasonable to include voice therapy in the
therapeutic strategy
 Patient collaboration and motivation is essential
