Effect of voice therapy in sulcus vocalis: A single case study.
BACKGROUND
Sulcus vocalis is a structural deformity of the vocal ligament. It is the focal invagination of the epithelium deeply attaching to the vocal ligament. There is a dearth of literature on the outcome of voice therapy in sulcus vocalis condition.


OBJECTIVE
The primary objective of this study was to document voice characteristics of sulcus vocalis and the secondary objective was to establish the efficacy of voice therapy in a patient with sulcus vocalis.


METHODS
A trial of voice therapy was given to the client who was diagnosed as having sulcus vocalis. Boon's facilitation techniques were used in voice therapy along with other techniques such as breath holding and push and pull approach prior to surgery. Acoustic, aerodynamic, perceptual, quantitative measures of voice quality and self-rating measurements were performed before and after voice therapy.


RESULTS
Improvement was noticed in 10/10 acoustic, 4/4 aerodynamic, perceptual, dysphonia severity index and voice handicap index scores, which hinted that voice therapy can be an option critically for clients with sulcus vocalis in the initial stage.


CONCLUSIONS
Voice therapy showed promising improvement in the study and it must be recommended as the initial treatment option before any surgical management.
