Objectives. Both acoustic and aerodynamic analyses are essential to evaluate the phonetic characteristics of voice pathology. The purpose of the study is to determine the magnitude of their correlation with the different types of bilabial plosive consonants.Methods. A controlled prospective study of 35 patients diagnosed with unilateral vocal fold paralysis was performed. The sustained vowel /a/ and bilabial voiceless consonants were used. Three common acoustic parameters were measured from a sustained vowel /a/ and aerodynamic parameters from a set of syllables /pi/, /p<sup>h</sup>i/, and /p’i/. We determined the correlation coefficients between acoustic and aerodynamic measurements for the bilabial plosive consonants /pi/, /p<sup>h</sup>i/, and /p’i/.Results. The mean values of acoustic parameters were higher than the thresholds of pathology. The mean values of aerodynamic parameters varied according to the types of consonants. The correlation between acoustic and aerodynamic parameters was significantly larger with the consonant /p<sup>h</sup>i/ compared with the consonants /p’/ and /p/. The magnitudes of correlation were higher with the consonant /p<sup>h</sup>i/ compared with the consonants /p’/ and /p/.Conclusion. The plosive consonant /p<sup>h</sup>i/ may represent a more valuable investigative consonant than the consonants /p/ or /p’/ for aerodynamic analysis of voice pathology, especially in patients with unilateral vocal fold paralysis.

AbstractObjective:To evaluate the functional results obtained after voice therapy in patients with unilateral vocal fold paralysis caused by different aetiologies.Design:Prospective analysis of the outcome of unilateral vocal fold paralysis cases treated at our speech and language rehabilitation service from November 2003 to January 2006. Thirty cases underwent behavioural treatment, between two and six weeks after unilateral vocal fold paralysis onset. A multi-dimensional assessment was carried out before, immediately after and six months after treatment.Results:After behavioural therapy, the prevalence of complete glottal closure increased significantly (p < 0.05). Subjects' pre-therapy mean values for jitter, shimmer and noise-to-harmonic ratio were statistically significantly different from those taken both immediately and six months after treatment (p < 0.05). The mean values for voice turbulence index significantly improved only six months after therapy (0.08 vs 0.04). At both post-treatment assessments, voice range profile analysis showed a significant decrease of lowest voice frequency and a significant increase of the number of semitones (p < 0.05). Mean values for grade, instability, breathiness, asthenia and voice handicap index scores were significantly decreased both immediately and six months after treatment, compared with pre-treatment values (p < 0.05).Conclusions:Early voice therapy may enable significant improvement in vocal function, allowing the patient to avoid surgery.

Objectives: For unilateral vocal fold paralysis (UVFP) with large posterior glottic gap medialization laryngoplasty (ML) + arytenoid adduction (AA), ML + adduction arytenopexy (AApexy), and ML alone using prosthesis with posterior extension are possible solutions. This study was carried out to elucidate the controversy among these solution options. Methods: Retrospective cohort. Tertiary referral center. One hundred forty patients with UVFP with large posterior glottic gap. Group 1 had 30 patients with ML + AA; Group 2 had 25 patients with ML + AApexy; Group 3 had 29 patients with ML using Isshiki prosthesis; Group 4 had 26 patients with ML using Montgomery prosthesis; Group 5 had 30 patients with ML using prosthesis with large posterior extension. Glottic closure using videolaryngostroboscopy, GRBAS, VHI-30, EAT-10, acoustic and aerodynamic analysis was carried out pre- and 1-year-postoperatively. Results: Preoperatively there was no significant difference in any parameters studied among all study groups ( P > .05). Except F0, speaking F0 and EAT-10, all other parameters in acoustic and aerodynamic analysis, glottic closure, GRBAS, and VHI-30 scores were significantly better postoperatively in Groups 1 and 2 compared to Groups 3 to 5 ( P < .05). Conclusions: In patients with UVFP and large posterior glottic gap, ML + AA and ML + AApexy seem to do better subjectively and objectively, acoustically and aerodynamically, when compared to ML using prosthesis with and without large posterior extension. ML alone does not appear to close posterior glottic gap. Therefore, it is a better and more reasonable option to perform arytenoid procedure when there is large posterior glottic gap in UVFP.

AbstractObjectives:(1) To evaluate the efficacy of modified arytenoid adduction in the management of patients with symptomatic cancer-related unilateral vocal fold paralysis, and (2) to assess the impact of this treatment on patients' quality of life.Methods:Forty-two patients with cancer-related unilateral vocal fold paralysis underwent modified arytenoid adduction between February 2001 and December 2008. Of these, 37 patients were enrolled in this retrospective study (one patient died of primary disease and four were lost to follow up). Laryngostroboscopy was performed to evaluate vocal fold orientation and mobility. Pre- and post-operative assessment of subjective and objective voice, aerodynamic parameters, and quality of life were also undertaken, and aspiration was subjectively rated.Results:Laryngostroboscopic findings indicated a significant post-operative improvement in vocal fold posterior glottal closure and vertical gap. Significant improvements in voice quality, aerodynamic parameters and quality of life were noted three months post-operatively in all patients (p < 0.01). The overall success rate for swallowing rehabilitation was 94.6 per cent (35/37). Subjective aspiration ratings decreased significantly post-operatively, compared with pre-operative values (p < 0.01). No major complication occurred in any patient, except for dyspnoea in one patient.Conclusion:Modified arytenoid adduction is an effective and reliable medialisation technique which can restore satisfactory voice quality, prevent aspiration and lead to a better quality of life for patients with cancer-related unilateral vocal fold paralysis.

<b><i>Introduction:</i></b> Unilateral vocal fold paralysis (UVFP) was a relative common glottic insufficiency disease; however, a completely satisfactory treatment of UVFP was elusive. This study was aimed to evaluate the surgical efficacy of modified arytenoid adduction with fenestration of the thyroid cartilage in the management of patients with UVFP, including voice and aspiration outcomes, and to summarize the postoperative complications. <b><i>Methods:</i></b> A retrospective analysis was performed on a total of 21 patients who underwent modified arytenoid adduction operation with fenestration of the thyroid cartilage for UVFP from July 2012 to June 2017. The scores of Grade, Roughness, Breathiness, Asthenia, Strain scale (GRBAS), voice self-satisfaction, dynamic laryngoscopy and the voice acoustic data (fundamental frequency [F0], fundamental frequency perturbation [jitter], loudness, amplitude perturbation [shimmer], and maximal phonatory time [MPT], etc.) were statistically analyzed preoperatively and 3–6 months postoperatively. The occurrence of postoperative complications was also summarized. <b><i>Results:</i></b> The voice subjective perception of 21 patients was significantly improved after operation. The rate of voice self-satisfaction was 90.5%. The mean values of voice acoustics parameters were significantly improved. The MPT was significantly longer (<i>p</i> &#x3c; 0.001), and the ratings of postoperative aspiration were significantly decreased compared with the preoperation. Among the 21 patients, 15 cases had sense of laryngeal obstruction, 8 cases had of 1–2° laryngemphraxis (recovered after 10–15 days). There were 2 cases of laryngeal stridor, 1 case of incision infection, 1 case of pharyngeal fistula, and 1 case of falsetto (corrected by voice training). No patient had laryngeal hematoma, neck hematoma, or laryngospasm. <b><i>Conclusion:</i></b> The modified arytenoid adduction operation with fenestration of the thyroid cartilage can significantly improve the vocal function of patients with UVFP and effectively reduce the aspiration, with fewer postoperative complications, less trauma, and more convenient advantages.
