“…The assessment should also include some standardized scale so that compounding variable can be reduced. One of the most commonly used scales is the GRBAS, developed by the Committee for Phonatory Function of the Japanese Society of Logopedics and Phoniatrics [10]. Morsomme et al [11] used the GRBAS scale to compare vocal quality in 28 patients with unilateral vocal fold paralysis and 12 controls.…”

The present study was undertaken to assess the efficacy of medialization thyroplasty on outcome of voice quality in vocal cord paralysis by analyzing the voice. A total 19 patients with vocal cord paralysis of different etiologies were included in the study. Preoperative voice analysis was done by voice recordings, GRBAS score, maximum phonation time (MPT) and acoustic analysis using Dr Speech software (University version 4.0) using habitual fundamental frequency (F0), jitter %, shimmer % and normalized noise energy (NNE) as parameters. 18 patients underwent type 1 or medialization thyroplasty alone and 1 patient had undergone medialization thyroplasty along with arytenoids adduction. Post operative voice analysis was done using same parameters. There was post operative improvement of voice in 16 patients whereas 3 patients showed no significant improvement. Mean preoperative MPT was 4.8947 s and post operative was 13 s. Mean preoperative GRBAS score was 76.1579 and post operative was 30. On acoustic analysis, mean preoperative habitual fundamental frequency (F0), jitter %, shimmer % and NNE was 278.16 Hz, 1.7, 6.81 and 1.81 dB respectively whereas post operative mean was 132.37 Hz, 0.41, 1.65 and 123.38 dB respectively. Thyroplasty offers good voice outcome in patients of uncompensated vocal cord paralysis. Improvement can be documented in terms of perceptual evaluation of voice and acoustic analysis as well as maximum phonation time in addition to voice recording.

“…Apart from self-assessment, voices were also evaluated by auditory–perceptual assessment using the GRB system [ 26 , 27 , 28 ]. Based on the GRBAS scale, our department developed the modified GRB classification [ 29 , 30 ]. Only the first three criteria are used, focusing on the overall grade of hoarseness (G) and both main pathophysiological hoarseness components: roughness (R) and breathiness (B).…”

The international nine-item Voice Handicap Index (VHI-9i) is a clinically established short-scale version of the original VHI, quantifying the patients’ self-assessed vocal handicap. However, the current vocal impairment classification is based on percentiles. The main goals of this study were to establish test–retest reliability and a sound statistical basis for VHI-9i severity levels. Between 2009 and 2021, 17,660 consecutive cases were documented. A total of 416 test–retest pairs and 3661 unique cases with complete multidimensional voice diagnostics were statistically analyzed. Classification candidates were the overall self-assessed vocal impairment (VHIs) on a four-point Likert scale, the dysphonia severity index (DSI), the vocal extent measure (VEM), and the auditory–perceptual evaluation (GRB scale). The test–retest correlation of VHI-9i total scores was very high (r = 0.919, p < 0.01). Reliability was excellent regardless of gender or professional voice use, with negligible dependency on age. The VHIs correlated best with the VHI-9i, whereas statistical calculations proved that DSI, VEM, and GRB are unsuitable classification criteria. Based on ROC analysis, we suggest modifying the former VHI-9i severity categories as follows: 0 (healthy): 0 ≤ 7; 1 (mild): 8 ≤ 16; 2 (moderate): 17 ≤ 26; and 3 (severe): 27 ≤ 36.

“…Deshalb setzte sich für die auditiv-perzeptive Stimmklangbeurteilung eine graduelle Klassifikation der Heiserkeit durch. Im deutschsprachigen Raum ist das RBH-System nach Wendler et al [ 16 ] üblich. Heiserkeit = H besteht entweder aus R = die Rauigkeit (Irregularitäten der Stimmlippenschwingung) oder B = die Behauchtheit (unmodulierte Ausatmenluft) bzw.…”

Hoarseness can be the leading symptom of dysphonia. In combination with impaired vocal performance and subjective voice-related discomfort, it can represent an individually different handicap for patients and lead to limited participation in social and professional life. Since the reasons for dysphonia may be not only functional but also organic with a potentially poor prognosis, hoarseness must be clarified using differential diagnosis. In addition to the knowledge of possible diseases, pathogenesis, and treatment options for dysphonia, the differential diagnostic approach requires profound knowledge of the various diagnostic methods, and of the interpretation of the results in particular. The etiology of dysphonia is very diverse and rarely monocausal. Therefore, a team-based and interdisciplinary differential diagnostic approach is recommended.
