Study on self-assessment, acoustic analysis, laryngoscopy for patients with voice surgery / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To study the self-assessment, acoustic analysis, laryngoscopy and its relationship for patients with voice disorders before and after surgery.@*METHODS@#Fifty patients with voice disorders were undergone self-assessment, acoustic analysis, and laryngoscopy before and after voice surgery. Self-assessment were done by voice handicap index (VHI) Scale Chinese version, including functional (F), physiological (P), emotion (E) and its sum denoted as T. Acoustic analysis were made for patient samples by Dr. Speech voice analysis software and jitter (J), shimmer (S), normalized noise energy (NNE) were selected as three parameters. Laryngoscopic examination were used to record the closure of vocal cord morphologically (C).@*RESULT@#In addition to E, F, P and T(VH) of VHI scale had a good correlation. In acoustic analysis J, S and NNE had a good correlation between them. F, P and T(VH) of VHI scale and acoustic analysis parameters J, S and NNE had a good correlation. Closed degree C and the VHI scale F, P and T(VH) as well as acoustic analysis parameters J, S, NNE had a good correlation. All the above data use were analyzed by Pearson correlation test.@*CONCLUSION@#VHI scale Chinese version make the patient's subjective feelings as the center, thus it has some limitations for the impact of East-West cultural differences, age, educational level and other factors. Acoustic analysis can show a detailed objective aspect of the patient's voice quality and evaluate the result of surgical treatment. Laryngoscopy provide an excellent morphological evidence. Consistency of three methods can do a comprehensive assessment for the voice disease.
