RESUMEN
In 2017, the International Dysphagia Diet Standardisation Initiative (IDDSI) introduced the IDDSI flow test which enables patients, clinicians, caregivers, food service professionals and researchers to classify liquid thickness into five levels based on the volume of liquid remaining in a standard 10 mL slip tip syringe after 10 s of flow under gravity. Within a few months of publishing the IDDSI flow test instructions, several barriers emerged: (1) the preferred model of syringe (BD 303134) was not equally accessible around the world, causing some users to perform flow tests with alternate models of syringe; (2) differences in syringe geometry across models led to variations in IDDSI flow test results; and (3) the need to use a second syringe for sample loading added complexity and cost to end users. To address these barriers, IDDSI designed the IDDSI funnel, a novel device, which combines the geometry of the BD 303134 syringe with a kitchen funnel to facilitate easy loading of liquid samples without need for a second syringe. In this report, we compare the IDDSI flow test results across two devices: syringe BD 303134 and IDDSI funnel. IDDSI level classifications were in complete agreement with the syringe reference test results in 67/73 (92%) of the test fluids and temperature conditions with mean difference of residual liquid across devices of 0.2 (2% full scale). These results demonstrate excellent correspondence between the two devices.

INTRODUCTION: To validate the Group for Learning Useful and Performant Swallowing (GLUPS), a clinical tool dedicated to videofluoroscopy swallowing study (VFSS). METHODS: Forty-five individuals were recruited from January 2022 to March 2023 from the Department of Otolaryngology Head and Neck Surgery of University Hospital Saint-Pierre (Brussels, Belgium). Subjects underwent VFSS, which was rated with GLUPS tool by two blinded otolaryngologists and one speech-therapist. VFSS were rated twice with GLUPS within a 7-day period to assess test-retest reliability. RESULTS: Twenty-four patients and twenty-one controls completed the evaluations. The internal consistency (α = 0.745) and the test-retest reliability (rs = 0.941; p = 0.001) were adequate. GLUPS reported a high external validity regarding the significant correlation with the Penetration-Aspiration Scale (rs = 0.551; p = 0.001). Internal validity was adequate, because GLUPS score was significant higher in patients compared to controls (6.21 ± 4.42 versus 2.09 ± 2.00; p = 0.001). Interrater reliability did not report significant differences in the GLUPS sub- and total score among the independent judges. The mean GLUPS score of individuals without any evidence of VFSS abnormalities was 2.09/23 (95% CI 1.23-2.95), which supported that a GLUPS score ≥ 3.0 is suggestive of pathological VFSS. CONCLUSIONS: GLUPS is a clinical instrument documenting the abnormal findings of oral and pharyngeal phases at the VFSS. GLUPS demonstrated high reliability and excellent criterion-based validity. GLUPS may be used in clinical practice for the swallowing evaluation at the VFSS.

INTRODUCTION: The Mann Assessment of Swallowing Ability (MASA) is a standardized clinical swallowing examination, specifically developed as a diagnostic test for the presence of oropharyngeal dysphagia and aspiration in the early period after stroke onset. In the original validation study, cutoff scores of <178 and <170 points, respectively, for the identification of dysphagia and aspiration risk are reported. However, a literature search revealed that alternative cutoff scores for dysphagia and/or aspiration provide better diagnostic accuracy. The aim of this secondary data analysis study was to evaluate the concurrent and predictive validity of the MASA. METHODS: Data were derived from a Belgian cohort study of an acute stroke population (n = 151). The MASA total score (MASA-TS), which is the sum of weighted scores on the 24 items, was evaluated against the Fiberoptic Endoscopic Dysphagia Severity Scale (FEDSS) to assess concurrent validity. To assess predictive validity of the MASA-TS, pneumonia during hospitalization and over 1 year and mortality acted as a future criterion. Analyses included receiver operating characteristic curves and area under the curve (AUC). RESULTS: Diagnostic accuracy of the MASA-TS was good for dysphagia (AUC = 0.85) and for the presence of relevant aspiration risk (AUC = 0.84). Using the original cutoff scores, the MASA-TS showed perfect sensitivity (Se = 1.00) for the identification of dysphagia and aspiration but inadequate specificity (Sp) for dysphagia (Sp = 0.16) and aspiration (Sp = 0.43). After determining new MASA cutoff scores, the optimal MASA cutoff scores were ≤146 for both dysphagia and aspiration with adequate thresholds (Se = 0.71 and Sp = 0.81 for dysphagia; Se = 0.73 and Sp = 0.80 for aspiration). The MASA-TS was a significant predictor of pneumonia during hospitalization (AUC = 0.85) and 1-year follow-up (AUC = 0.86), and of mortality (AUC = 0.79). CONCLUSION: The MASA-TS showed good concurrent validity with the FEDSS. Furthermore, using new cutoff scores (≤146 for the identification of dysphagia and aspiration) lead in general to more accurate diagnostic indexes. The MASA-TS is a good predictor of aspiration pneumonia during hospitalization and 1-year follow-up and of mortality.

INTRODUCTION: Positive effects from tongue-strengthening exercises (TSE) are widely described, but dose-dependent studies concerning exercise frequency have not yet been reported. This study aimed to determine the training and detraining effects of TSE with exercise frequencies of respectively 3 and 5 times per week on maximum isometric anterior and posterior tongue pressures (MIPA and MIPP) and on anterior and posterior tongue strength during an effortful saliva swallow (PswalA and PswalP). METHOD: Twenty healthy adults were randomly assigned to two exercise groups, training 3 (EX3, n = 10) or 5 (EX5, n = 10) times per week with the Iowa Oral Performance Instrument. MIPA, MIPP, PswalA, and PswalP were measured at baseline, after 4 and 8 weeks of training and 4 and 8 weeks after the last training session to document detraining effects. Descriptive statistics, linear mixed model effects, and post hoc analyses were calculated. RESULTS: Significant increases in MIPA, MIPP, PswalA, and PswalP were measured for training both 3 and 5 times per week. No significant differences on any parameter were found between EX3 and EX5 groups. No significant detraining effects were found after 4 or 8 weeks in any treatment arm either for MIPs or for effortful swallow pressures. CONCLUSION: This randomized study demonstrated a positive effect of TSE on MIP and Pswal in healthy older adults, without detraining effects. No superiority of exercise frequency was identified based on significance testing, although some trends are discussed.

OBJECTIVE: To assess the internal consistency, reliability, and clinical validity of a French version of the M.D. Anderson Dysphagia Inventory (Fr-MDADI). METHODS: Patients addressed in the Swallowing Clinics of CHU Saint-Pierre Hospital (Brussels) and EpiCURA hospital (Ath, Belgium) for dysphagia completed Fr-MDADI, eating assessment tool-10 (EAT-10), dysphagia handicap index (DHI), and benefited from fiberoptic endoscopic evaluation of swallowing (FEES) and videofluoroscopy. Seventy-two asymptomatic individuals composed the control group. The reliability of Fr-MDADI was assessed through a test-retest procedure. The validity was assessed by comparing Fr-MDADI with EAT-10 scores. Normative value of Fr-MDADI was calculated through the receiver operating characteristic (ROC) curve. RESULTS: Forty-two patients and 77 healthy individuals completed the evaluations (33 males). The main etiology of dysphagia was head and neck cancers. The internal consistency was high regarding the Cronbach's alpha (0.864). The test-retest reliability was high for Fr-MDADI total scores (rs = 0.849). The Fr-MDADI emotional, functional and physical subscores, and the total score exhibited high positive correlations with EAT-10 (rs = 0.770) and DHI (rs = 0.811), exhibiting high external validity. Patients had significant higher item and total score of Fr-MDADI compared with healthy individuals (control group), which indicated an adequate internal validity. About normative data, a Fr-MDADI > 13 was considered to be reflective of abnormalities. The 'swallowing-induced cough' item of the Fr-MDADI was significantly associated with the occurrence of aspirations regarding objective examinations (FEES or videofluoroscopy; p = 0.001). CONCLUSION: The Fr-MDADI is a reliable and valid self-administered tool in the evaluation of the dysphagia of French-speaking patients.

OBJECTIVE: To develop a French version of the Eating Assessment Tool (Fr EAT-10) and to assess its internal consistency, reliability and clinical validity. METHODS: Fifty-six patients referred in the Swallowing Clinics of CHU Saint-Pierre Hospital (Brussels) and EpiCURA hospital (Ath, Belgium) for dysphagia were enrolled and completed fiberoptic endoscopic evaluation of swallowing and videofluoroscopy. Seventy-three asymptomatic subjects were included in the study. To assess reliability, Fr-EAT-10 was completed twice within a 7-day period. Validity was assessed by comparing Fr-EAT-10 scores with the scores of dysphagia handicap index (DHI) in all individuals. Normative value of EAT-10 was calculated and the receiver operating characteristic (ROC) curve was used to determine the best Fr-EAT-10 threshold associated with aspiration. RESULTS: Fifty-two patients completed the study. Cronbach's alpha was 0.95 indicating a high internal consistency. Test-retest reliability was high in the entire cohort (rs = 0.921). The correlation between Fr-EAT-10 total scores and DHI was high (rs = 0.827) indicating a high external validity. Patients had a significant higher score of Fr-EAT-10 than the controls (p < 0.001) exhibiting a high internal validity. The analysis of normative data reported that a score of Fr-EAT-10 > 3 should be considered as abnormal. The correlation between Fr-EAT-10 and the occurrence of aspiration is significant (rs = 0.327, p < 0.05). According to the ROC curve; aspirations need to be highly suspected for patients with Fr-EAT-10 ≥ 17. CONCLUSION: The Fr-EAT-10 developed in this study is a reliable and valid self-administered tool in the evaluation of dysphagia in French-speaking patients.

BACKGROUND: Radiation-associated-dysphagia is a serious side effect of radiotherapy (RT) for head and neck cancer (HNC). METHODS: Seventy-six patients had a weekly prospective follow-up from baseline until one week post-RT. Combined mixed model analysis (n = 43) determined the evolution of self-perceived swallowing function, isometric tongue strength (MIP), tongue strength (TS) during swallowing (Pswal), and quality of life (QoL) in these patients during RT. RESULTS: Swallowing deteriorated from the third week on, resulting in an increase of tube dependency from 10% at baseline toward 31% post-RT. Both MIP and Pswal are reduced, with anterior MIP decreasing in 29% of patients and posterior MIP in 17%. Pswal decreases for saliva and a bolus swallow. All QoL subscales except "sleep" were affected during RT. CONCLUSIONS: Self-perceived swallowing function, TS and QoL decrease during RT for HNC. Current findings highlight the need for early monitoring of these parameters.

Tongue strength and its role in the pathophysiology of dysphagia in adults are well accepted and studied. An objective and reliable measurement of tongue strength in children necessitates equally good methodology, knowledge of influencing factors, and normative data. Only limited data on testing tongue strength in children are available thereby limiting its potential use. The present study examined tongue strength and several parameters known to be important in adults in the largest sample of healthy children from 3 to 11 years old to date using the Iowa Oral Performance Instrument with standard bulbs. Tongue strength increases markedly for children between 6 and 7 years, with slower increases before and after this age. Unlike adults, no influence of sex or location was found on the maximum tongue strength in children, and visual feedback was found to be counterproductive in obtaining the highest tongue pressures. The normative data obtained can be used for objective assessment of tongue weakness and subsequent therapy planning in dysphagic children.

Tongue-strengthening exercises (TSE) are based on the principles of exercise and motor learning, including intensity. Intensity is manipulated by gradually adjusting the resistive load. This randomized controlled trial (RCT) investigates the effect of three different values resistive load during TSE in healthy older adults. Sixty subjects completed 8 weeks of TSE while exercising with Iowa Oral Performance Instrument (IOPI). They were randomly distributed to 4 different treatment arms: 3 exercise groups (EG1: n = 15; EG2: n = 16, EG3: n = 16) and 1 control group performing lip-strengthening exercises (CG: n = 13). Values of resistive load for EG1, EG2, and EG3 were 100, 80, and 60% 1RM, respectively. Anterior and posterior maximal isometric pressures (MIPA, MIPP) were measured at baseline, after 4 and 8 weeks of training and 4 weeks post-training. MIPA and MIPP in the EG were significantly higher than in the CG at all time points, except baseline. No significant differences between EG were found, but some trends were observable. Anteriorly, the higher the resistive load, the higher the increase in MIP. Posteriorly, 100% 1RM caused the highest values, followed by 60% and 80% 1RM. No detraining effects were measured. The degree of exercise load had a significant negative effect on the registered success rate. This RCT confirms the efficacy of TSE in healthy older adults. For MIPA and MIPP, TSE at a resistive load of 100% 1RM are the most efficient choice in this population, while lowering the resistive load will lead to an increased success rate. No detraining effects were registered.

One of the major limitations of the fiberoptic endoscopic evaluation of swallowing (FEES) is related to the challenging application of temporal measures. Among them, Whiteout (WO) is due to pharyngeal and tongue base contraction and might be used as an estimation of the pharyngeal phase duration. The aims of this study were to evaluate the inter- and intrarater reliability of WO duration and to appraise the effects of age, sex, volume, and texture of the boluses on this temporal measurement. A total of 30 healthy volunteers were recruited. According to their age, the subjects were grouped into three different age groups. Each of them underwent FEES examination with different textures (liquid, semisolid, and solid) and volumes. FEES examinations were video recorded, processed with the software Daisy Viewer 2.0, which allowed the acquisition of 25 frames per second (s) and analyzed by three different raters in order to collect data on WO duration. A total of 863 swallowing acts were video recorded. Intra- and interrater reliability of WO duration were excellent. Both volume and bolus's texture significantly affected WO duration. In particular, WO duration was significantly shorter for the liquid texture than for the semisolid and solids ones. In addition, male subjects scored significantly higher values of WO duration. Finally, WO duration was significantly higher in seniors. WO duration seems to be a reliable temporal measure during FEES examination. WO duration seems to be affected by several factors such as age, sex, volume, and consistency.

Clinical tongue-strengthening therapy programs are generally based on the principles of exercise and motor learning, including the specificity paradigm. The aim of this study was to investigate the specific effect of anterior and posterior tongue-strengthening exercises (TSE) on tongue strength (TS) in healthy older adults and to measure possible detraining effects. Sixteen healthy elderly completed 8 weeks of TSE by means of the Iowa Oral Performance Instrument (IOPI). They were distributed in two different treatment arms and performed either exclusively anterior or posterior TSE (ATSE, n = 9 or PTSE, n = 7) depending on the treatment arm. Anterior and posterior maximal isometric pressures (MIPA, MIPP) were measured at baseline, halfway, and after completion of the training sessions. Detraining was measured by repeating MIPA and MIPP measures 4 weeks after the last session of TSE. MIPA and MIPP increased significantly in both treatment arms. MIPA was significantly higher in the ATSE group compared to the PTSE group across all measures in time. No significant differences were observed in MIPP between the ATSE and PTSE groups. Regardless of treatment arm, there was no significant detraining effect measured 4 weeks after the last TSE session. This study suggests that TSE show partial specificity concerning bulb position. We conclude that especially anterior training results in higher anterior TS in comparison with posterior exercises. Furthermore, we found no detraining effects, independent of bulb location.

PURPOSE: The aim of this study was to investigate the feasibility of tongue strength measures (TSMs) and the influence of bulb location, sex, and self-perceived pain and mucositis in head and neck cancer (HNC) patients during chemoradiotherapy (CRT). METHODS: Twenty-six newly diagnosed HNC patients treated with CRT performed anterior and posterior maximal isometric tongue pressures by means of the Iowa Oral Performance Instrument (IOPI). The Oral Mucositis Weekly Questionnaire (OMWQ) and a Visual Analogue Scale (VAS) for pain during swallowing were completed weekly from baseline to 1 week post CRT. RESULTS: Feasibility of TSMs during CRT declines significantly from 96 to 100% at baseline to 46% after 6 weeks of CRT. But post-hoc analyses reveal only significant differences in feasibility between baseline and measurements after 4 weeks of treatment. No effect of gender or bulb location was established, but feasibility is influenced by pain and mucositis. CONCLUSIONS: Feasibility of TSMs declines during CRT and is influenced by mucositis and pain. For the majority of subjects, TSMs were feasible within the first 4 weeks, which provides a window of scientific and clinical opportunities in this patient population.

BACKGROUND: The Swallowing Quality-of-Life Questionnaire (SWAL-QoL) is considered the gold standard for assessing health-related QoL in oropharyngeal dysphagia. The Dutch translation (DSWAL-QoL) and its adjusted version (aDSWAL-QoL) have been validated using classical test theory (CTT). However, these scales have not been tested against the Rasch measurement model, which is required to establish the structural validity and objectivity of the total scale and subscale scores. Thus, the purpose of this study was to examine the psychometric properties of these scales using item analysis according to the Rasch model. METHODS: Item analysis with the Rasch model was performed using RUMM2030 software with previously collected data from a validation study of 108 patients. The assessment included evaluations of overall model fit, reliability, unidimensionality, threshold ordering, individual item and person fits, differential item functioning (DIF), local item dependency (LID) and targeting. RESULTS: The analysis could not establish the psychometric properties of either of the scales or their subscales because they did not fit the Rasch model, and multidimensionality, disordered thresholds, DIF, and/or LID were found. The reliability and power of fit were high for the total scales (PSI = 0.93) but low for most of the subscales (PSI < 0.70). The targeting of persons and items was suboptimal. The main source of misfit was disordered thresholds for both the total scales and subscales. Based on the results of the analysis, adjustments to improve the scales were implemented as follows: disordered thresholds were rescaled, misfit items were removed and items were split for DIF. However, the multidimensionality and LID could not be resolved. The reliability and power of fit remained low for most of the subscales. CONCLUSIONS: This study represents the first analyses of the DSWAL-QoL and aDSWAL-QoL with the Rasch model. Relying on the DSWAL-QoL and aDSWAL-QoL total and subscale scores to make conclusions regarding dysphagia-related HRQoL should be treated with caution before the structural validity and objectivity of both scales have been established. A larger and well-targeted sample is recommended to derive definitive conclusions about the items and scales. Solutions for the psychometric weaknesses suggested by the model and practical implications are discussed.

The Swallowing Quality-of-Life questionnaire (SWAL-QoL) is considered the gold standard for assessing health-related quality of life in people with dysphagia. However, many dysphagic patients struggle to complete this questionnaire because of additional functional sequelae such as language impairment and cognitive disorders. In this study, we sought to develop an adjusted Dutch version of the SWAL-QoL (aDSWALQoL) and to evaluate its psychometric properties and feasibility compared with the original questionnaire. We developed the aDSWAL-QoL based on recommendations from previous literature. The feasibility, internal consistency, test-retest reliability, and criterion validity of the aDSWAL-QoL were evaluated in 78 dysphagic patients, among whom 43 had additional language and/or cognitive impairments (DysLC). Statistical analyses were performed using SPSS 20.0. The aDSWAL-QoL had a higher degree of feasibility for the DysLC group. We obtained high Cronbach's α coefficients for total scale and for almost all subscales. Total aDSWAL-QoL scores showed excellent testretest agreement and good criterion validity with respect to the DSWAL-QoL. Almost all subscales showed significantly moderate to good test-retest agreement and criterion validity. However, the psychometric properties of the 'Food selection' subscale were inadequate. The aDSWAL-QoL is a feasible, reliable, and valid tool for use with DysLC patients. Conversion of the aDSWAL-QoL into an audio computer-assisted self-administered format should be investigated. The construct validity of the aDSWAL-QoL will be evaluated in a separate report.

BACKGROUND: The aim of this study was to investigate the feasibility and reliability of the Oral Health Assessment Tool (OHAT) as used by speech pathologists, to become part of a comprehensive clinical swallowing examination. METHODS: A multicentre study in 132 elderly subjects was conducted by speech pathologists. The inter-rater, test-retest and intra-rater reliabilities of the OHAT were assessed in R statistics, version 3.0.1. Intraclass correlation coefficients (ICCs) were used for the total OHAT, and Kappa statistics were used for the individual categories. RESULTS: Total OHAT scores showed good inter-rater (ICC = 0.96), intra-rater (ICC ≥ 0.95) and test-retest (ICC ≥ 0.78) agreement. The inter-rater Kappa statistics were almost perfect (κ ≥ 0.83) for seven of the eight individual categories of the OHAT and perfect for 'dental pain' (κ = 1.00). The test-retest Kappa statistics indicated excellent agreement for 'natural teeth' and 'dentures' (κ ≥ 0.86). The intra-rater per cent agreement was excellent for all categories except 'gums and tissues'. CONCLUSIONS: This is the first study to examine the feasibility and reliability of the OHAT as used by speech pathologists. As the results showed both good feasibility and reliability, the OHAT has the potential to add to the clinical swallowing examination. However, future research investigating actual referral strategies and adaptation of care strategies following assessment with OHAT is needed.

BACKGROUND: Reduced tongue strength is an important factor contributing to early and late dysphagia in head and neck cancer patients previously treated with chemoradiotherapy. The evidence is growing that tongue strengthening exercises can improve tongue strength and swallowing function in both healthy and dysphagic subjects. However, little is known about the impact of specific features of an exercise protocol for tongue strength on the actual outcome (strength or swallowing function). Previous research originating in the fields of sports medicine and physical rehabilitation shows that the degree of exercise load is an influential factor for increasing muscle strength in the limb skeletal muscles. Since the tongue is considered a muscular hydrostat, it remains to be proven whether the same concepts will apply. METHODS/DESIGN: This ongoing randomized controlled trial in chemoradiotherapy-treated patients with head and neck cancer investigates the effect of three tongue strengthening exercise protocols, with different degrees of exercise load, on tongue strength and swallowing. At enrollment, 51 patients whose dysphagia is primarily related to reduced tongue strength are randomly assigned to a training schedule of 60, 80, or 100% of their maximal tongue strength. Patients are treated three times a week for 8 weeks, executing 120 repetitions of the assigned exercise once per training day. Exercise load is progressively adjusted every 2 weeks. Patients are evaluated before, during and after treatment by means of tongue strength measurements, fiber-optic endoscopic evaluation of swallowing and quality-of-life questionnaires. DISCUSSION: This randomized controlled trial is the first to systematically investigate the effect of different exercise loads in tongue strengthening exercise protocols. The results will allow the development of more efficacious protocols. TRIAL REGISTRATION: Current Controlled Trials ISRCTN14447678.

The aim of this work was to evaluate the psychometric properties of the Dutch version of the Swallowing Quality-of-Life Questionnaire (DSWAL-QOL). A cross-sectional survey of 295 dysphagic patients and 124 healthy controls was studied to evaluate the validity and reliability of the DSWAL-QOL, and 50 patients were recruited for the test-retest reliability. Construct validity was validated through principal component analysis and a correlation study between the DSWAL-QOL and the SF-36. The psychometric properties of the DSWAL-QOL were found to be largely similar to those of the original SWAL-QOL, except the Sleep scale; the composite Symptoms score reaffirms its validity in this study. The DSWAL-QOL was able to differentiate between dysphagic and nondysphagic patients and is sensitive to disease severity as measured by known-groups validity, based on different food and liquid textures. The DSWAL-QOL is a clinically valid and reliable tool for assessing the quality of life in Dutch-speaking dysphagic patients, regardless of the cause or severity of the dysphagia.

This study collected data on the maximum anterior and posterior tongue strength and endurance in 420 healthy Belgians across the adult life span to explore the influence of age, sex, bulb position, visual feedback, and order of testing. Measures were obtained using the Iowa Oral Performance Instrument (IOPI). Older participants (more than 70 years old) demonstrated significantly lower strength than younger persons at the anterior and the posterior tongue. Endurance remains stable throughout the major part of life. Gender influence remains significant but minor throughout life, with males showing higher pressures and longer endurance. The anterior part of the tongue has both higher strength and longer endurance than the posterior part. Mean maximum tongue pressures in this European population seem to be lower than American values and are closer to Asian results. The normative data can be used for objective assessment of tongue weakness and subsequent therapy planning of dysphagic patients.

Unilateral vocal fold paralysis can result in incomplete glottic closure, compromising the vocal efficiency and increasing the risk of aspiration. The glottic gap can be reduced by medialization thyroplasty. Both silicone and titanium implants have been described to be efficient in the improvement of the vocal outcome. The aim of this study was to assess the vocal outcome after medialization thyroplasty using silicone and titanium implants and to compare the results of the two implanted materials using prospective sequential cohort study. 24 patients underwent medialization thyroplasty, performed under local anaesthesia with intravenous sedation: 10 patients were included in the silicone cohort and 14 in the titanium cohort. All patients underwent vocal assessment preoperatively and postoperatively, using the Voice Handicap Index, the GRBASI scale, maximum phonation time and the Dysphonia Severity Index. Postoperative analysis of the entire population showed statistically significant improvement for the Voice Handicap Index, maximum phonation time, Dysphonia Severity Index and the parameters G, B and A of the GRBASI scale (83% follow up). Subgroup analysis showed a statistically significant greater improvement of Voice Handicap Index of the titanium cohort compared with the silicone cohort. Improvement of maximum phonation time, Dysphonia Severity Index and GRBASI scale of the titanium cohort was greater than improvement of the silicone cohort, but this difference was not statistically significant. Both silicone and titanium medialization implants showed improvement of vocal outcome, the results of the titanium implant being superior.
