“…6 Arytenoid adduction is also used to close a moderate-to-large glottal gap, and there is a synergistic effect on combining this technique with nerve transfer. 24 Although these procedures are more effective for large glottal gaps than injection laryngoplasty, injection laryngoplasty has become widely applied for UVFP because of the simplicity of the procedure and the development of diverse materials, such as hyaluronic acid, micronized acellular dermis, bovine collagen, and calcium hydroxyapatite. 25,26 In addition, early vocal fold injection with temporary material may decrease the rate of permanent medialization procedure compared with conservative management, such as observation and voice therapy in cases of UVFP.…”

“…It has been found that HNR is correlated with the perceptual assessment of hoarseness [60] and vocal clarity [61]. HNR has been an important and commonly used outcome measure of voice treatment [62,63]. Praat 6.1.40 [51] was used to measure HNR from the middle 3-s segments from three trials of vowel samples and the averaged result (in dB) was used for the statistical analysis.…”

Background: Although voice therapy is the first line treatment for muscle-tension voice disorders (MTVD), no clinical research has investigated the role of specific active ingredients. This study aimed to evaluate the efficacy of active ingredients in the treatment of MTVD. A retrospective review of a clinical voice database was conducted on 68 MTVD patients who were treated using the optimal phonation task (OPT) and sob voice quality (SVQ), as well as two different processes: task variation and negative practice (NP). Mixed-model analysis was performed on auditory–perceptual and acoustic data from voice recordings at baseline and after each technique. Active ingredients were evaluated using effect sizes. Significant overall treatment effects were observed for the treatment program. Effect sizes ranged from 0.34 (post-NP) to 0.387 (post-SVQ) for overall severity ratings. Effect sizes ranged from 0.237 (post-SVQ) to 0.445 (post-NP) for a smoothed cepstral peak prominence measure. The treatment effects did not depend upon the MTVD type (primary or secondary), treating clinicians, nor the number of sessions and days between sessions. Implementation of individual techniques that promote improved voice quality and processes that support learning resulted in improved habitual voice quality. Both voice techniques and processes can be considered as active ingredients in voice therapy.

The Impact of Nasalance on Cepstral Peak Prominence and Harmonics‐to‐Noise Ratio

Objectives/Hypothesis Cepstral peak prominence (CPP) has been reported as a reliable measure of dysphonia and a preferred alternative to harmonics‐to‐noise ratio (HNR). However, CPP has been observed to be sensitive to articulatory variation and vocal intensity. The aim of this study was to examine the impact of nasalance on CPP and HNR of voice signals. It was hypothesized that increased nasalance would be associated with decreased CPP. Study Design Within‐subject correlation design. Methods Thirty vocally healthy female participants were recorded reading and producing a vowel in alternation with a nasal consonant while wearing a nasometer for calculation of nasalance. Recorded vowel, nasalized, and nasal segments of speech were used to calculate CPP using Analysis of Dysphonia in Speech and Voice software, and HNR and vocal intensity using Praat software. Results Significant main effects of conditions were observed for CPP. CPP values decreased significantly when phonation changed from vowel to nasalized vowel and to nasal. There was correlation between CPP and nasalance and between CPP and intensity. HNR was slightly higher in the nasal condition than in vowel. There was a weak correlation between HNR and nasalance. No correlation was found between HNR and intensity. Conclusions CPP is sensitive to changes in vocal tract configuration caused by nasalization as well as intensity, whereas HNR is not. Therefore, CPP may reflect the periodicity in source signal or the filtering effects of vocal tract. Further research is needed to clarify the application and interpretation of CPP in clinical practice. Level of Evidence 4 Laryngoscope, 129:E299–E304, 2019

Vocal Outcome After Arytenoid Adduction and Ansa Cervicalis Transfer

Abstract: Treatment with AA + ACN-RLN provides near-normal vocal function in the 24-month follow-up. Therefore, this method could be a successful surgical treatment for severe paralytic dysphonia.
