Multi parametric voice assessment: sri ramachandra university protocol.

Emergence of "Voice specialty clinics" in ENT and Speech Language Pathologist (SLP) practice in India necessitates development of standard protocols for assessment and management of voice disorders. Based on recommendations from European Laryngological Society in Dejonckere (Eur Arch Otorhinolaryngol 258:77-82, 2001), a comprehensive voice assessment protocol was adapted for Indian population. This study aimed at verifying the face validity and feasibility of using the developed voice assessment protocol in a multi specialty tertiary care hospital. It included: history, clinical examination, visual analysis, perceptual analysis, aerodynamic measures, acoustic analysis and patients' self assessment of voice. The developed protocol was administered on 200 patients with voice concerns and problems. Correlation of self assessment with the assessment by the professionals was done using Kendaul tau_b correlation test. The scores of self assessment did not correlate significantly with acoustic measures. Differences in lab findings and self percept of voice indicated that these two were complementary measures in the protocol. Further, diagnosis and management decisions were arrived through a consensus discussion involving the ENT surgeon, SLP and the patient. Vocal hygiene and voice conservation were advised to all patients. Recommendations for voice therapy and/or surgery were provided based on findings from the protocol. The study demonstrated feasibility of using a comprehensive protocol for effective documentation, comparisons, review, training and treatment planning.
