“…Some studies have demonstrated no significant differences in f0 when comparing pre- and post-treatment recordings, 23,24,33–38 nor between normal subjects and those with phonotraumatic lesions. 35,36 Conversely, others have reported either increased 25,39,40 or decreased 24,41 f0 values for patients with nodules or polyps relative to normal subjects and/or following surgery.…”

Objectives Clinical management of phonotraumatic vocal fold lesions (nodules, polyps) is based largely on assumptions that abnormalities in habitual levels of sound pressure level (SPL), fundamental frequency (f0), and/or amount of voice use play a major role in lesion development and chronic persistence. This study used ambulatory voice monitoring to evaluate if significant differences in voice use exist between patients with phonotraumatic lesions and normal matched controls. Methods Subjects were 70 adult females: 35 with vocal fold nodules or polyps and 35 age-, sex-, and occupation-matched normal individuals. Weeklong summary statistics of voice use were computed from anterior neck surface acceleration recorded using a smartphone-based ambulatory voice monitor. Results Paired t-tests and Kolmogorov-Smirnov tests resulted in no statistically significant differences between patients and matched controls regarding average measures of SPL, f0, vocal dose measures, and voicing/voice rest periods. Paired t-tests comparing f0 variability between the groups resulted in statistically significant differences with moderate effect sizes. Conclusions Individuals with phonotraumatic lesions did not exhibit differences in average ambulatory measures of vocal behavior when compared with matched controls. More refined characterizations of underlying phonatory mechanisms and other potentially contributing causes are warranted to better understand risk factors associated with phonotraumatic lesions.

“…In studies where the sample was divided into two groups, only 10 specified the type of vocal pathology [12,13,[16][17][18]20,[24][25][26]28]. In addition, none of the studies specified how the calculation of the sample size or the sampling procedure was performed.…”

“…The voice evaluation techniques assessed in the different included studies are highly heterogeneous. In 10 of the studies [12,15,16,20,21,[23][24][25]28] only acoustic parameters were registered, two included only aerodynamic parameters [13,22], and in seven [14][15][16][17][18]26,27,29,30] both parameters were recorded. Only one study assessed the acoustic parameters together with the myoelectric activity [19].…”

“…Table 1 shows the summary of the methodology used in the 19 studies included in the review. In most of them, a sample made up of two groups was observed: an experimental group made up of people with vocal pathology and a control group made up of people without vocal pathology [12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Another three were made up of a group of volunteers with vocal pathology [26][27][28] and two more were composed of volunteers without vocal pathology [29,30].…”

Acoustic, Myoelectric, and Aerodynamic Parameters of Euphonic and Dysphonic Voices: A Systematic Review of Clinical Studies

Background: At present, there is no clinical consensus on the concept of normal and dysphonic voices. For many years, the establishment of a consensus on the terminology related to normal and pathological voices has been studied, in order to facilitate the communication between professionals in the field of the voice. Aim: systematically review the literature to compare and learn more precisely the measurable and objective characteristics of the acoustic, aerodynamic and surface electromyographic parameters of the normal and dysphonic voices. Methods: The PRISMA 2020 methodology was used as a review protocol together with the PICO procedure to answer the research question through six databases. Results: In total, 467 articles were found. After duplicate records were removed from the selection, the inclusion and exclusion criteria were applied and 19 articles were eligible. A qualitative synthesis of the included studies is presented in terms of their methodology and results. Conclusions: Studying the acoustic, aerodynamic, and electromyographic parameters with more precision, in both normal and dysphonic voices, will allow health professionals working in the field of voice (speech therapy, otorhinolaryngology, phoniatrics, etc.) to establish a diagnostic and detailed consensus of the vocal pathology, enhancing the communication and generalization of results worldwide.

To evaluate the stroboscopic and acoustic results obtained with larynx fiberendoscopic surgery (LFS) to remove pedunculated vocal fold polyps. Prospective study, comparing before and after surgery results. We used a series of 31 patients, with a pedicled vocal fold polyp. To remove the pedunculated polyp, we used LFS. This technique consists of excising vocal fold injuries under local anaesthesia by means of micro tweezers using a canal larynx fiberscope. Subjects were evaluated on three occasions: before surgery, 2 and 4 weeks after surgery. After surgery, improvement obtained in stroboscopy examination was statistically significant (p < 0.001) and 100% of the patients had recovered a mucosal wave. After 4 weeks of surgery, all acoustic parameters reached normality ranges. LFS used for the removal of pedunculated vocal fold polyps produces acoustic and stroboscopic improvements, comparable to those obtained using direct laryngoscopy.
