"Lombard Effect" and Voice Changes in Adductor Laryngeal Dystonia: A Pilot Study.

OBJECTIVES: The aim was to describe the acoustic, auditory-perceptive, and subjective voice changes under the Lombard effect (LE) in adductor laryngeal dystonia (AdLD) patients. METHODS: Subjective perception of vocal effort (OMNI Vocal Effort Scale OMNI-VES), Maximum Phonation Time (MPT), and the perceptual severity of dysphonia (GRBAS scale) were assessed in condition of stillness and under LE in 10 AdLD patients and in 10 patients with typical voice. Speakers were asked to produce the sustained vowel /a/ and to read a phonetically balanced text aloud. Using the PRAAT software, the following acoustic parameters were analyzed: Mean Pitch (Hz), Minimum and Maximum Intensity (dB), the Fraction of Locally Unvoiced Frames, the Number of Voice Breaks, the Degree of Voice Breaks (%), the Cepstral Peak Prominence-Smoothed (CPPS) (dB). RESULTS: Under LE, the AdLD group showed a decrease of both G and S parameters of GRBAS and subjective effort, mean MPT increased significantly; in the controls there were no significant changes. In both groups under LE, pitch and intensity of the sustained vowel /a/ significantly increased consistently with LE. In the AdLD group the mean gain of OMNI-VES score and the mean gain of each parameter of the speech analysis were significantly greater than the controls' ones. CONCLUSION: Auditory feedback deprivation obtained under LE improves subjective, perceptual-auditory, and acoustics parameters of AdLD patients. These findings encourage further research to provide new knowledge into the role of the auditory system in the pathogenesis of AdLD and to develop new therapeutic strategies.

Automatic speaking valve in tracheo-esophageal speech: treatment proposal for a widespread usage.

PURPOSE: Aim of this study was to calculate the percentage of the Automatic Speaking Valve (ASV) use in a large cohort of laryngectomized patients with voice prosthesis (VP) and to analyze the main reasons for non-use. Subsequently, a specific rehabilitation training was proposed. METHODS: One hundred-ten laryngectomized patients with VP were enrolled in the first phase of the study (census). Among them, 57 patients were included in the second phase (intervention), in which a training based on moving phonatory exercises was proposed. Structured questionnaires were used before and after training in order to investigate ASV use rate (days/week and hours/day; reasons for impeding the ASV use), average adhesive life-time during ASV use; hands-free speech duration; skin irritation. Patients also expressed their degree of on a VAS scale from 0 to 100. RESULTS: In the census phase the percentage of use of ASV (everyday, without problems) was equal to 17.27% (19/110 patients). The main causes of disuse concerned excessive fatigue and poor durability of the adhesives. The analysis of the results pre vs. post-training showed a statistically significant increase (p < 0.05) in all the investigated parameters. Patients reported a good level of treatment compliance (average frequency of performing exercises equal to 4.2 ± 2.5 days/week for 1.4 ± 1.01 h/day) and high degrees of satisfaction. After treatment, the percentage of use of AVS increased by 43% reaching a rate of 60% (66/110 patients). CONCLUSION: A specific and targeted approach that simulate the phonatory and breathing difficulties of everyday life can increase the ASV usage rate.

Perceptual Evaluation of the Tracheoesophageal Voice: Italian Validation of the Sunderland Tracheoesophageal Perceptual Scale.

OBJECTIVES: This study aimed to validate the Sunderland Tracheoesophageal Perceptual Scale (SToPS) in the Italian language by checking the inter- and intra-rater reliability. STUDY DESIGN: Scale validation METHODS: The validation of the tool involved the following steps: (1) translation and adaptation of the SToPS into Italian language; (2) recruitment of participants (60 laryngectomized patients with a voice prosthesis and 12 health professionals-six speech and language therapists (SLTs) and six ear, nose, and throat surgeons-classified into experienced (Exp) or not at assessing voice; (3) recording of patients' speech samples; (4) perceptual evaluation of recorded speech samples (test and retest) performed by the 12 health professionals; and (5) statistical analysis (quadratic weighted Cohen kappa and weighted kappa of Light coefficients). RESULTS: When all raters were considered as one group, an agreement ≥0.50 was reached for all parameters. The "ExpSLTs" group rated more reliably than the other groups, achieving a "good" intrarater agreement for 9/10 parameters. Despite the interrater coefficients were lower than the intrarater ones for all rater groups, "ExpSLTs" obtained the best levels of interrater agreement, achieving a level of agreement ≥0.50 for all parameters. Finally, considering intrarater+interrater agreement ("good + good" or "good + moderate"), the "ExpSLTs" group showed the greatest agreement, attaining all parameters that met the criteria for "good" or "moderate" agreement levels. CONCLUSIONS: The Italian version of SToPS can be considered a reliable tool. As in the original version, expert SLTs are the better judges for tracheoesophageal voice assessment.

Rehabilitation After Total Laryngectomy: An Integrated Protocol Remotely Delivered During COVID-19.

The aim of this paper was to evaluate the results of an integrated treatment delivered remotely to laryngectomized patients with voice prosthesis. Eighteen laryngectomized patients were treated remotely in groups co-led by a speech therapist and a psychologist ("Online Group"). The results were compared with those of 17 patients ("In-Person Group") previously studied. The two groups obtained comparable results on all parameters of the INFVo perceptual rating scale, in the DEP, ANX, PHO and HOS areas of the Symptom Check List-90-Revised questionnaire, and in the areas investigated by the WHOQOL-B questionnaire. The "In-Person Group" obtained statistically better results on the Italian Self-Evaluation of Communication Experiences after Laryngeal Cancer questionnaire. Although the in-person treatment favored the acceptance of the new voice and the development of conversational skills, telerehabilitation guaranteed an adequate level of assistance in terms of voice acquisition, prevention of anxiety and depression, and recovery of a good QoL.

Combined treatment of muscle tension dysphonia: voice therapy with instrumental postural rehabilitation.

Objectives: This investigation aimed to propose a new rehabilitation technique that combines voice exercises and instrumental postural rehabilitation for patients with muscle tension dysphonia (MTD). Methods: We enrolled nine dysphonic patients (8 women and 1 man, aged 22-55 years). Voice assessment included strobovideolaryngoscopy, Maximum Phonation Time (MPT), perceptual evaluation by GRBAS scale and patient's self-rating by Italian version of the Voice Handicap Index (VHI). Vestibular function was evaluated by the Bed Side Examination and Video Head Impulse test (VHIT). Postural control was evaluated by Dynamic Posturography (DP) using the Sensory Organization Test (SOT) and analysing the Equilibrium Score (ES) and balance subsystems (somatosensorial, visual, vestibular). Results: All cases underwent different types of voice exercises combined with balance training based on NeuroCom Balance Master Protocols, once a week for six 35-minutes sessions. After therapy, an improvement in MPT, VHI, GRBAS scores and endoscopic laryngeal features was obtained. DP results at baseline were normal and after therapy we showed a slight improvement of ES (somatosensorial and visual components). Conclusions: A combined rehabilitation technique for MTD, by improving the attention to postural control, allows for significant improvement in vocal symptoms.

Improving Hands-Free Speech Rehabilitation in Laryngectomized Patients with a Moldable Adhesive.

OBJECTIVE: This study aims to assess the product performance of a new moldable peristomal adhesive with corresponding heating pad designed to facilitate and improve automatic speaking valve (ASV) fixation for hands-free speech in laryngectomized patients. METHODS: Twenty laryngectomized patients, all regular adhesive users with prior ASV experience, were included. Study-specific questionnaires were used for data collection at baseline and after two weeks of moldable adhesive use. The primary outcome parameters were adhesive lifetime during hands-free speech, use and duration of hands-free speech, and patient preference. Additional outcome parameters were satisfaction, comfort, fit, and usability. RESULTS: The moldable adhesive enabled ASV fixation adequate for hands-free speech in the majority of participants. Overall, the moldable adhesive significantly increased adhesive lifetime and duration of hands-free speech compared to participants' baseline adhesives (p < 0.05), regardless of stoma depth, skin irritation, or regular use of hands-free speech at baseline. The participants who preferred the moldable adhesive (55% of participants) experienced a significant increase in the adhesive lifetime (median of 24 h, range 8-144 h) and improved comfort, fit, and ease of speech. CONCLUSION: The moldable adhesive's lifetime and functional aspects, including the ease of use and custom fit, are encouraging outcomes and enable more laryngectomized patients to use hands-free speech more regularly.

Gender-related differences in the prevalence of voice disorders and awareness of dysphonia.

Objective: Considering the impact of dysphonia on public health and the increasing attention to patient-centred care, we evaluated sex-related differences in the prevalence of benign voice disorders, awareness of dysphonia and voice therapy (VT) results. Methods: One hundred and seventy-one patients, 129 females and 42 males, with functional or organic benign dysphonia underwent Voice Handicap Index (VHI), auditory-perceptual dysphonia severity scoring (GRBAS) and acoustic analysis (Jitter%, Shimmer%, NHR) before and after VT. Results: Prevalence of each voice disorder was significantly higher among females. Mean time-to-diagnosis (time elapsed until medical consultation) was not different between males and females. The refusal of therapy and VT adherence (mean number of absences and premature dropout) were similar in the two groups. Pre-VT VHI and "G" parameter were worse in women. The percentage of women with abnormal acoustic analysis was significantly higher. Post-VT VHI gain was higher in women, whereas "G" parameter improvement did not differ by sex. Conclusions: Our study showed a higher prevalence of voice disorders in females. Awareness of dysphonia was not gender related. Females started with worse voice subjective perception and acoustic analysis, but they perceived greater improvement after therapy.

Multidimensional voice assessment after Lee Silverman Voice Therapy (LSVT®) in Parkinson's disease.

Objective: To investigate the effectiveness of Lee Silvermann Voice Treatment (LSVT®) in improving prosody in patients with Parkinson's disease over medium-term follow-up. Methods: 15 patients with Parkinson's disease were assessed before LSVT®, within one week, and 3 and 6 months after treatment. Subjective and objective evaluation included: Voice Handicap Index - 10 (VHI-10), perceptual assessment by GRBAS scale and item 18 of the Unified Parkinson's Disease Rating Scale III (UPDRS III), maximum phonation time (MPT /s/) and acoustic analysis by means the Voice Range Profile (VRP) and the "Intonation Stimulability Protocol" of the Motor Speech Profile (MSP). Results: A significant increase of the mean values of Imax and rF0 was observed until 6 months post-therapy (p < 0.001), whereas Running Speech Standard Deviation (rSTD) (p = 0.004), Amplitude Variability (rVAm) (p = 0.02) and Frequency Variability (rvF0) (p = 0-01) improved significantly after 3 months, but returned to pre-therapy levels after 6 months. The score of item 18 of the UPDRS III increased significantly early post-therapy (p = 0.03), but did not maintain the improvement at 3 and 6 months. Median values of Grade (G), Asthenia (A) and mean values VHI-10 score significantly decreased at each post-therapy control (p < 0.05). Conclusions: In addition to the subjective and perceptual beneficial effect of LSVT®, we found a long-lasting increase of loudness and fundamental frequency. There was also improvement of acoustic parameters related to prosody, although it was temporary.

Voice Telerehabilitation in Iatrogenic Unilateral Vocal Fold Paralysis: From Necessity to Opportunity in the COVID-19 Time.

OBJECTIVE: To evaluate results of telerehabilitation (TR) during the coronavirus disease 2019 pandemic for the treatment of dysphonia caused by permanent post-thyroidectomy unilateral vocal fold paralysis (UVFP). METHODS: Forty subjects with post-thyroidectomy UVFP (onset <1 month) underwent TR. Videostrobolaryngoscopy, acoustic and perceptual voice analysis and patient self-assessment were carried out in person before, at the end of TR and 6 months later. RESULTS: Twenty-five subjects spontaneously recovered full vocal fold motility at some time during follow-up, whereas 15 had a permanent UVFP at the end of the follow-up period. These subjects constituted our study group. At the early posttherapy control 10/15 subjects (66.6%) showed a complete glottal closure, while in 5/15 (33.3%) a glottal gap remained (P = 0.03). These results did not change 6 months after TR. At the late posttherapy control the maximum phonation time improved significantly (P = 0.02). Both post-therapy Voice Handicap Index scores were significantly lower than the pre-therapy ones (P = 0.04). Grade, Breathiness, and Asthenia parameters of the Grade-Roughness-Breathiness-Asthenia-Strain scale improved 6 months after TR (P < 0.05). The number of voice signals suitable for acoustic analysis increased significantly after therapy. Finally, 87% of patients were satisfied with TR. CONCLUSIONS: With careful patient selection, TR may be considered as a promising method for voice therapy in postthyroidectomy UVFP.

Optimizing Pulmonary Outcomes After Total Laryngectomy: Crossover Study on New Heat and Moisture Exchangers.

OBJECTIVE: To evaluate the effects of new devices-heat and moisture exchangers (HMEs) and adhesives-on pulmonary symptoms, subject adherence, quality of life, dermatologic symptoms, and patient satisfaction after laryngectomy. STUDY DESIGN: Prospective crossover study. SETTING: Between December 2020 and April 2021, 40 patients were enrolled who had undergone laryngectomy, routinely used HMEs and adhesive, and were followed in our Department of Otolaryngology-Head and Neck Surgery. METHODS: Patients were allocated into group A (new products) or group B (usual care) for 6 weeks. Then the 2 groups reversed, and each patient acted as his or her own control. Patients kept a diary and cough tally sheet. At baseline and after each 6-week period, 2 questionnaires were administered: EQ-5D (European Quality of Life-5 Dimensions) and CASA-Q (Cough and Sputum Assessment Questionnaire). RESULTS: Six weeks of using new products resulted in the following effects for both groups: (1) a significant reduction in daily forced expectoration and dry coughs, (2) a significant improvement in all domains of the CASA-Q, (3) an increase in adherence to HME use, (4) a significant reduction in shortness of breath and skin irritation, and (5) significantly better scores in the anxiety/depression domain of the EQ-5D. CONCLUSION: Achieving this reduction in patients who were already highly adherent to HME use is clinically relevant and underscores the importance of using better-performing HMEs that can compensate for the humidification deficit. Improving pulmonary symptomatology could reduce patient restrictions in daily life and avoidance of social activity, with a consequent positive effect on quality of life.

Speech perception in noise in children with dyslexia: Does speech sound disorder matter?

The aim of this observational cohort study with a control group is to compare consonant perception skills in quiet and in noise in children with typical language and learning development and in children with dyslexia, with and without Speech Sound Disorder (SSD). Three groups were included: A control group of twenty children with normal reading abilities and typical language development, twelve children with dyslexia and typical language development and thirteen children with dyslexia and SSD. All subjects received a consonant recognition test in three different listening conditions (quiet, + 10 and 0 Signal-to-Noise Ratio). In all test conditions, children with dyslexia and SSD had significantly lower consonant recognition scores than the control group and the children with dyslexia and typical language development (p < .0001). The poorer performances observed in children with dyslexia and SSD may be explained by impaired phonological processing underlying both conditions.

Long-term voice outcomes and quality of life after open partial horizontal laryngectomy type II vs. total laryngectomy: A cross-sectional study.

OBJECTIVES: We aim to analyse long-term voice outcomes and quality of life (QoL) in patients undergoing open partial horizontal laryngectomy type II (OPHL type II) and to compare them to those obtained by patients undergoing total laryngectomy (TL) with voice prosthesis (VP). DESIGN: Cross-sectional cohort study. SETTING: Patients undergoing surgery for advanced laryngeal cancer, assessed during the usual follow-up consultations at the Phoniatric Unit (February 2020-December 2020). PARTICIPANTS: Forty-five patients were enrolled and divided into two groups: OPHL group and TL group. MAIN OUTCOMES MEASURES: Acoustic analysis, maximum phonation time, INFV0  scale, I-SECEL, UW-QoL-V4 and MDADI questionnaires were used to assess the long-term outcomes. RESULTS: Voices of patients undergoing OPHL Type II were worse than those of laryngectomised patients with VP. Nevertheless, scores in voice and dysphagia-related QoL were comparable and scores in the social domain of QoL were higher in OPHL group. CONCLUSIONS: Open partial horizontal laryngectomy Type II allows an acceptable voice recovery and a satisfactory QoL.

Oropharyngeal Dysphagia After Hospitalization for COVID-19 Disease: Our Screening Results.

A high percentage of patients suffered symptoms also after recovery from the Coronavirus Disease-2019 (COVID-19) infection. It is not well clear what are the specific long-term sequelae (complications and symptoms). During the acute phase the patients may develop a multi-organ system pathology including aerodigestive tract. As the pathophysiology of COVID-19 emerges, the aim of our study was to describe the prevalence of oropharyngeal dysphagia after COVID-19 disease. From March to July 2020 we enrolled patients recovered from SARS-CoV-2 infection who had been previously hospitalized for the disease. They were screened for dysphagia by mean of the Eating Assessment Tool-10 (EAT-10). The cases with EAT-10 score > 3 were graded for the aspiration risk by applying the Gugging Swallowing Screen (GUSS) and were submitted to the Swal-QoL questionnaire. The cases with a GUSS score > 19 were subjected to FEES. 8/117 (7%) patients had positive screening result. 4/8 (50%) revealed an abnormal health related quality of life in oropharyngeal dysphagia with a mean Swal-QoL score of 69.73. The most affected domain was the "time of meals" (mean score 65) following by the "sleep" (mean score 66) and "eating desire" (mean score 72). 1/8 cases showed increased risk for aspiration and did not showed endoscopic signs of oropharyngeal dysphagia. Our results showed that the prevalence of upper dysphagia after hospitalization for SARS-CoV-2 is not anecdotal and that probably this long-lasting sequela has a psychogenic etiology.

Oropharyngoesophageal Scintigraphy in a Case of Complex Swallowing Disorders After a Major Oral Surgery.

ABSTRACT: A 75-year-old woman had an occasional finding of a left tonsil mass for dysphagia, which resulted a high-grade squamous carcinoma. Therefore, the patient was sent to have a left pharyngectomy. After the pharyngectomy, the patient reported persistent swallowing disorders and nasal reflux. Consequently, she had an oropharyngoesophageal scintigraphy, demonstrating irregular oral and pharyngeal swallowing phases and confirming reflux episodes into the rhinopharynx and into the oropharynx. In line with these findings, the patient was send to rehabilitation; the abnormal functional mechanisms, previously identified by the scintigraphy, allowed to guide the speech therapy, with a progressive clinical improvement.

Regenerative Strategy for Persistent Periprosthetic Leakage around Tracheoesophageal Puncture: Is It an Effective Long-Term Solution?

Autologous tissue-assisted regenerative procedures have been considered effective to close different types of fistula, including the leakage around tracheoesophageal puncture. The aim of this study was to retrospectively review 10 years of lipotransfer for persistent periprosthetic leakage in laryngectomized patients with voice prosthesis. Clinical records of patients who experienced periprosthetic leakage from December 2009 to December 2019 were reviewed. Patients receiving fat grafting were included. The leakage around the prosthesis was assessed with a methylene blue test. Twenty patients experiencing tracheoesophageal fistula enlargement were treated with fat grafting. At the one-month follow-up, all patients were considered improved with no leakage observed. At six months, a single injection was sufficient to solve 75% of cases (n 15), whereas 25% (n 5) required a second procedure. The overall success rate was 80% (n 16). Results remained stable for a follow-up of 5.54 ± 3.97 years. Fat grafting performed around the voice prosthesis, thanks to its volumetric and regenerative properties, is a valid and lasting option to solve persistent periprosthetic leakage.

Periprosthetic Leakage in Tracheoesophageal Prosthesis: Proposal of a Standardized Therapeutic Algorithm.

OBJECTIVE: Periprosthetic leakage represents the most demanding long-term complication in the voice prosthesis rehabilitation. The aim of this article is to discuss the various causes of periprosthetic leakage and to propose a systematic management algorithm. STUDY DESIGN: Retrospective cohort study. SETTING: Otolaryngology clinic of the University Polyclinic A. Gemelli-IRCCS Foundation. METHODS: The study included 115 patients with voice prosthesis who were treated from December 2014 to December 2019. All patients who experienced periprosthetic leakage were treated with the same step-by-step therapeutic approach until it was successful. Incidence, management, and success rate of every attempt are analyzed and discussed. RESULTS: Periprosthetic leakage was reported 330 times by 82 patients in 1374 clinic accesses. Radiotherapy, timing of tracheoesophageal puncture, and type of total laryngectomy (primary or salvage) did not influence the incidence of periprosthetic leakage. Salvage total laryngectomy increases the risk of more clinically relevant leakages. CONCLUSION: By using a systematic algorithm with a step-by-step standardized approach, periprosthetic leakage management could become a less treacherous issue.

Patients With Voice Prosthesis Rehabilitation During the COVID-19 Pandemic: Analyzing the Effectiveness of Remote Triage and Management.

OBJECTIVE: To describe a remote approach used with patients with voice prosthesis after laryngectomy during the COVID-19 pandemic and the resulting clinical outcomes in terms of voice prosthesis complications management, oncological monitoring, and psychophysical well-being. STUDY DESIGN: Prospective cohort study. SETTING: Otolaryngology Clinic of the University Polyclinic A. Gemelli, IRCCS Foundation. SUBJECTS AND METHODS: All patients with voice prosthesis who underwent laryngectomy followed by our institute were offered enrollment. Patients who agreed to participate were interviewed to inquire about the nature of the need and to plan a video call with the appropriate clinician. Before and 1 week after the clinician's call, patients were tested with the Hospital Anxiety and Depression Scale. Degrees of satisfaction were investigated with a visual analog scale. A comparison between those who accepted and refused telematic support was carried out to identify factors that influence patient interest in teleservice. RESULTS: Video call service allowed us to reach 37 (50.68%) of 73 patients. In 23 (62.16%) of 37 cases, the video call was sufficient to manage the problem. In the remaining 14 cases (37.83%), an outpatient visit was necessary. Participants who refused telematic support had a significantly shorter time interval from the last ear, nose, and throat visit than patients who accepted (57.95 vs 96.14 days, P = .03). Video-called patients showed significantly decreased levels of anxiety and depression (mean Hospital Anxiety and Depression Scale total score pre- vs post-video call: 13.97 vs. 10.23, P < .0001) and reported high levels of satisfaction about the service. CONCLUSION: Remote approach may be a viable support in the management of patients with voice prosthesis rehabilitation.
