Quantitative Evaluation of Vocal Bowing Following Bilateral Thyroplasty in Age-Related Vocal Atrophy.

Age-related vocal atrophy (ARVA) is associated with vocal fold bowing, persistent glottal gap during phonation, and dysphonia. Bilateral medialization thyroplasty is sometimes performed in patients with ARVA to improve vocal fold closure and voice. We set out to quantify stroboscopic changes in vocal fold bowing, glottal closure, and abduction angle following bilateral thyroplasty and determine how these changes affect voice quality among patients with ARVA. Fifteen individuals with ARVA who underwent bilateral medialization thyroplasty were included in this study. Two independent investigators calculated bowing index (BI), normalized glottal gap area (NGGA), and maximum abduction angle from laryngostroboscopic exams using ImageJ™. Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and patient-reported measures were collected before and after thyroplasty. Thyroplasty resulted in a 10-point improvement in overall CAPE-V (Mean dif -10; 95% CI -17, -3.3, p < 0.01) and VHI-10 (mean dif -3.8; 95% CI -9.8, 2.3, p = 0.19, n = 8). NGGA and BI significantly decreased following surgery (mean dif -78; 95% CI -155, -1.5, p = 0.05; and mean dif -2.1; 95% CI -2.4, -0.84, p < 0.01, respectively). BI correlated with CAPE-V scores (r = 0.66, 95% CI 0.22, 0.87, p < 0.01). When considering the normalized combined contributions of both NGGA and BI, there was a stronger correlation in CAPE-V scores (r = 0.87, 95% CI 0.50, 0.97, p < 0.01) compared with either measure alone. Thyroplasty resulted in a decrease in vocal fold bowing, glottal gap area, and CAPE-V scores in patients with ARVA. Correction of vocal bowing and glottal gap, following bilateral thyroplasty, improved voice measures following surgery. Quantitative evaluation of vocal fold morphology may be valuable when assessing the severity and treatment-response in patients with ARVA following bilateral thyroplasty.

Comparison of Voice Therapy Outcomes: Clinic vs Telehealth

Voice therapy provides patients with valuable exercises and techniques to optimize vocal behaviors and improve their ability to communicate effectively and efficiently. These sessions were typically held by speech-language pathologists (SLPs) in clinic. During the COVID-19 pandemic, SLPs were provisionally able to provide billable voice therapy services in telehealth format. There is a lack of existing research studies comparing outcomes based on the format of voice therapy. A retrospective chart review was performed on 101 patients who underwent voice therapy at a large academic institution in order to compare outcomes between clinic, telehealth, and mixed voice therapy formats. Demographics, dysphonia etiology, duration of symptoms, number of therapy sessions, and pre- and postvoice therapy scores using reflux symptom index (RSI), voice handicap index (VHI-10), consensus auditory-perceptual evaluation of voice (CAPE-V), and Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) scoring were collected. Statistical comparisons were performed using Fisher's exact test and analysis of covariance. There were no statistically significant differences in pre- to postvoice therapy RSI, VHI-10, CAPE-V, or GRBAS scores based on format of voice therapy, after adjustment for number of therapy sessions received. There were no differences in these outcomes when comparing voice therapy by etiology of dysphonia. Overall, these data support the effectiveness of the telehealth voice therapy format. It is a promising platform for greater patient access to therapy. All formats of voice therapy were effective in improving key measures of voice perception.

Pediatric Dysphonia: When to Refer.

The reported prevalence of voice disorders in the pediatric population varies widely between studies, ranging from 3.9% to 23%. Despite this, not all children with dysphonia are referred to a voice specialist for further evaluation. The objective of this study is to examine the relationship between dysphonia history, voice assessment, and laryngeal findings to help guide referrals of dysphonic children. A retrospective review was conducted of pediatric patients at a tertiary voice clinic between January 2014 and December 2017. Data including dates of presentation, demographics, co-morbidities, presenting symptoms, laryngeal exam findings, Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) scores, and Pediatric Voice Handicap Index (pVHI) scores were collected and analyzed. Of 475 patients initially identified, 459 met inclusion criteria and were reviewed. In all, 272 (59.3%) were male and 187 (40.7%) were female. Mean age at first presentation was 8.6 years old (range: 2-18). Males were more likely to present at a younger age than females. CAPE-V data were available for 439 patients, and pVHI data were available for 109 patients. The mean CAPE-V Overall Severity score was 38.2. The mean total pVHI score was 25.4. Males had higher CAPE-V Overall Severity (40.0 vs. 35.4), Roughness (32.2 vs. 27.6), and Strain scores (37.2 vs. 32.4) than females. Patient pVHI scores did not differ by gender. In all, 283 patients self-reported a length of symptoms prior to evaluation. Children with a longer duration of symptoms prior to evaluation had higher CAPE-V Overall Severity scores. Diagnoses of vocal fold movement impairment and benign vocal fold lesions that were not nodules were associated with higher average CAPE-V Overall Severity scores. Overall, 310 patients (67.5%) were recommended intervention for their dysphonia. These patients had higher CAPE-V Overall Severity scores than those who were solely recommended observation (42.8 vs. 28.0). Males were more likely than females to present with dysphonia and presented with more severe perceptual dysphonia scores on average. The length of symptoms and certain diagnoses correlated with higher CAPE-V Scores. Referrals to a pediatric voice clinic should be considered in patients with a dysphonia history lasting greater than 3 months and in patients with more severe symptoms.

Telehealth for Treatment of Pediatric Dysphonia

Vocal fold nodules are the most common etiology of chronic dysphonia in the pediatric population. Voice therapy is an effective first line of treatment, with increasing evidence supporting the use of telepractice in speech pathology. Despite this, there is limited data on its effectiveness in the pediatric population. The aim of this retrospective study was to investigate the feasibility and efficacy of telepractice in delivering voice therapy to children diagnosed with vocal fold nodules. A retrospective review was conducted of patients treated with virtual voice therapy from April 2020 to June 2021. Patients were included if diagnosed with vocal fold nodules, 2-18 years of age, and completed therapy in a virtual format. Data includes demographics, Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) scores and pediatric Voice Handicap Index (pVHI) scores. Twenty-three children were included, 17 (74%) male and six (26%) female (with an age range of 2.4-9.9 years at the start of therapy). Prior to treatment, the average CAPE-V Overall Severity score was 37.9 (SD 13.8); the average posttreatment score was 22.4 (SD 10.2). The average pVHI total score prior to treatment was 26.3 (SD 12.1), with an average posttreatment score of 20.2 (SD 11.7). Patients who underwent virtual voice therapy had improved posttreatment CAPE-V severity scores than those prior to treatment (average difference = -15.5 points; 95% CI: -8.3 to -22.7; P < 0.001). An increased number of therapy sessions was associated with both higher initial CAPE-V severity scores (r = 0.72; P < 0.01) and a greater decrease in posttreatment CAPE-V scores (r = -0.55; P < 0.01). Virtual voice therapy may be feasible and efficacious in treating dysphonic children diagnosed with vocal fold nodules. Significant improvements were found in perceptual CAPE-V scores in overall severity; positive changes were also seen in parental measures of quality of life. Delivery of voice therapy in a telehealth format may increase access of care and should be considered as a treatment option.

Patient reported voice handicap and auditory-perceptual voice assessment outcomes in patients with COVID-19

Purpose The purpose of this study is to compare patient-reported voice handicap and auditory-perceptual measures of voice between healthy individuals and COVID-19 patients, as well as to investigate the effect of clinical factors on voice quality. Methods COVID-19 patients (n = 138) and 90 healthy controls were included in the study. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) was used to grade voice samples based on overall severity, roughness, breathiness, strain, pitch, and loudness. The Voice Handicap Index-10 was completed by all participants (VHI-10). Physical (pVHI), emotional (eVHI) and functional (fVHI) subscores were calculated. Clinical data were collected (disease stage, CT grade, neutrophil/lymphocyte ratio, CRP, and symptoms). Results A statistically significant difference between patient and control groups in VHI-10 and CAPE-V scores was detected (p < 0.001). Except eVHI, total score and all subscale scores were higher in patients with COVID-19 as the pVHI was the most affected (η2 = 0.324) subscale. All scores of CAPE-V were significantly worse in patients with COVID-19 as highest impact of COVID-19 was on breathiness (η2 = 0.518). Pre-existing pulmonary comorbidity, dyspnoea and N/L was significantly associated with the VHI-10 overall score (βpc = 4.27, βdyspnoea = 5.69 and βnl = 0.25). The overall severity of CAPE-V was significantly dependent on dyspnoea and pulmonary comorbidity (βdyspnoea = 11.25, βpc = 10.12). VHI ≥4 and CAPE-V overall severity ≥11 were good indicators of COVID-19 related dysphonia. Conclusions COVID-19 causes patient-reported voice handicap and deteriorates auditory-perceptual measures of voice. COVID-19 related voice impairment was mainly associated with the decreased respiratory capacity.

Long-Term Voice Outcomes Following Cricotracheal Resection for Subglottic Stenosis: A Retrospective Analysis.

Cricotracheal resection (CTR) is an effective treatment for refractory idiopathic subglottic stenosis (iSGS) but is associated with persistent dysphonia. Outcomes were measured longitudinally to characterize how patients' voices and self-perceived voice handicaps changed after CTR. Retrospective case-series. We conducted a retrospective cohort study of patients with refractory iSGS treated by CTR from 2006 to 2017. Voice Handicap Index (VHI), Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), and acoustic analysis were prospectively collected preoperatively and postoperatively at 1, 3, 6, 12, and 24-month intervals. A linear mixed model was used to evaluate temporal change. Thirty-three patients (97% female) were included. VHI scores increased significantly from baseline preoperative score (27.2 ± 22.7) to a mean value of 44.3 ± 25.6 (P< .001) 1-month postoperatively but decreased below preoperative scores after 2 years (18.8 ± 11.9, P= .795). Mean fundamental frequency (F0) values in speech decreased significantly from 192.0 ± 24.9 Hz preoperatively to 167.1 ± 19.8 Hz at a 2-year follow-up (P= .002), with a nadir value at 1-month postoperatively (148.4 ± 20.5, P< .001). CAPE-V scores increased significantly from preoperative to 1-month postoperative (3.0 ± 2.3 vs. 21.9 ± 17.3, P< .001) but returned toward baseline values at 24 months after CTR (6.9 ± 4.8, P= .027). CAPE-V measurements postoperatively were correlated with VHI and F0 (Pearson coefficient=0.54 (VHI), -0.46 (F0), P< .001). Following CTR, mean F0 values were significantly and consistently lower but did increase over time, correlating with patients' improving VHI and CAPE-V scores. VHI values indicate that patient's perception of their voice is not significantly impacted in long term. These results provide a framework to counsel patients about long term voice expectations. 4 Laryngoscope, 132:1054-1060, 2022.

Cultural and Linguistic Adaptation of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) Into Hindi.

Aim The purpose of this study was to develop and assess the reliability of a Hindi version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). Reliability was assessed by comparing Hindi CAPE-V ratings with English CAPE-V ratings and by the Grade, Roughness, Breathiness, Asthenia and Strain (GRBAS) scale. Method Hindi sentences were created to match the phonemic load of the corresponding English CAPE-V sentences. The Hindi sentences were adapted for linguistic content. The original English and adapted Hindi CAPE-V and GRBAS were completed for 33 bilingual individuals with normal voice quality. Additionally, the Hindi CAPE-V and GRBAS were completed for 13 Hindi speakers with disordered voice quality. The agreement of CAPE-V ratings was assessed between language versions, GRBAS ratings, and two rater pairs (three raters in total). Pearson product-moment correlation was completed for all comparisons. Results A strong correlation (r > .8, p < .01) was found between the Hindi CAPE-V scores and the English CAPE-V scores for most variables in normal voice participants. A weak correlation was found for the variable of strain (r < .2, p = .400) in the normative group. A strong correlation (r > .6, p < .01) was found between the overall severity/grade, roughness, and breathiness scores in the GRBAS scale and the CAPE-V scale in normal and disordered voice samples. Significant interrater reliability (r > .75) was present in overall severity and breathiness. Conclusions The Hindi version of the CAPE-V demonstrates good interrater reliability and concurrent validity with the English CAPE-V and the GRBAS. The Hindi CAPE-V can be used for the auditory-perceptual voice assessment of Hindi speakers.

The Effects of Endoscopic Sinus Surgery on Voice Characteristics in Chronic Rhinosinusitis Patients.

Functional endoscopic sinus surgery (FESS) is a standard treatment modality for patients with chronic rhinosinusitis (CRS) who have failed appropriate medical therapy. However, FESS entails modification of the upper airway tract that may alter phonatory resonance and produce voice changes. The effects of FESS on postoperative voice characteristics in patients with CRS have yet to be quantitatively assessed. Patients with severe CRS who underwent FESS at a tertiary care referral center between May and October 2017 were prospectively enrolled. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and the Voice Handicap Index (VHI) were used to quantitatively evaluate voice characteristics and quality of life, respectively. Preoperative and postoperative CAPE-V and VHI scores were compared with postoperative scores for each patient. Sino-Nasal Outcome Test (SNOT-22) scores were also obtained to assess changes in patient symptoms. 18 CRS patients undergoing FESS were enrolled. The average preoperative Lund-Mackay score was 14, indicating baseline severe CRS. Postoperative assessments demonstrated a statistically significant decrease in CAPE-V (45-27, p = .005) and VHI (10-4.7, p < .001) scores. These correlated with a statistically significant decrease in SNOT-22 scores (42-13, p < .001). Patients with CRS experience a significant improvement in voice characteristics and vocal quality of life following FESS. Furthermore, this appears to correlate with a significant decrease in self-reported disease severity. These findings may augment the discussion of potential benefits of FESS to a new potential domain for voice quality.

Pediatric dysphonia: It's not about the nodules

ObjectiveDespite the fact that vocal nodules are the most common cause of chronic dysphonia in children, uncertainty and lack of consensus complicates practically every diagnostic and management decision. Selecting an optimal staging system is fundamental to understanding a disease process, mandatory for uniform reporting, and crucial to predicting natural history and treatment outcomes. The ideal prognostic model for vocal nodules is under intense debate. The purpose of this study was to analyze the predictive power of vocal nodule grade to severity of voice metrics in children. MethodsSeventy-nine patients diagnosed with vocal cord nodules between 2006 and 2012 were drawn from UPMC Children's Hospital of Pittsburgh Voice, Resonance and Swallowing Center Research Registry. Subject age at time of diagnosis, nodule grade, relevant co-morbidities, scores on The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), parent-reported Pediatric Voice Handicap Index (pVHI), the phonotraumatic behaviors profile, habitual speaking pitch fundamental frequencies, pitch range, volume intensity, and s/z ratio were recorded and compiled into a de-identified database for analysis. ResultsBased on the Kruskal-Wallis H Test, there was no statistically significant correlation between nodule grade and total pitch range (p = .21), s/z ratio (p = .50), volume intensity (p = .33), overall CAPE-V Scores (p = .15), or pVHI Scores (p = .29). Chi-squared tests also revealed no significant associations between nodule grade and abnormality in habitual speaking pitch (p = .14 for fundamental frequency while sustaining a vowel sound, p = .37 for fundamental frequency while speaking structured tasks i.e. counting, or p = .76 while speaking in conversation). ConclusionThe current “gold-standard” for grading vocal nodule size suggests that the nodules themselves are not driving the standard dysphonic metrics that are most commonly collected and monitored in such children. This outcome is consistent with other studies reporting similar findings and was expected based on the inconsistencies in the reported literature to date. By extension, the conventional wisdom of avoiding surgical treatment of vocal nodules in children seems prudent as there is little evidence to suggest that the nodules themselves are “driving” the severity of the dysphonia. Ultimately identifying the true “drivers” of dysphonia in children will suggest alternative therapies that are more specific and directed to the pathophysiology. Most pediatric voice care professionals will welcome such discoveries as those in the front line of patient care are often rendered helpless and frustrated.

Reliability and Validity of the Turkish Version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V)

The main purpose of this study was to culturally adapt the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) to Turkish and to evaluate its internal consistency, validity, and reliability. The Turkish version of CAPE-V was developed, and with the use of a prospective case-control design, the voice recordings of 130 participants were collected according to CAPE-V protocol. Auditory-perceptual evaluation was conducted according to CAPE-V and Grade, Roughness, Breathiness, Asthenia, and Strain (GRBAS) scale by two ear, nose, and throat specialists and two speech and language therapists. The different types of voice disorders, classified as organic and functional disorders, were compared in terms of their CAPE-V scores. The overall severity parameter had the highest intrarater and inter-reliability values for all the participants. For all four raters, the differences in the six CAPE-V parameters between the study and the control groups were found to be statistically significant. Among the correlations for the comparable parameters of the CAPE-V and the GRBAS scales, the highest correlation was found between the overall severity-grade parameters. There was no difference found between the organic and functional voice disorders in terms of the CAPE-V scores. The Turkish version of CAPE-V has been proven to be a reliable and valid instrument to use in the auditory-perceptual evaluation of voice. For the future application of this study, it would be important to investigate whether cepstral measures correlate with the auditory-perceptual judgments of dysphonia severity collected by a Turkish version of the CAPE-V.

Dysphonia in extremely preterm children: A longitudinal observation

Introduction. Dysphonia is a potential long-term complication of preterm birth. Childhood voice disorders caused by vocal hyperfunction resolve with pubertal changes to the vocal mechanism in many cases. In extremely preterm children, whose voice quality is affected by supraglottic hyperfunction adapted secondary to underlying structural laryngeal pathology sustained during neonatal intubation, the prognosis is unknown.Methods. A pilot study was conducted to assess the incidence and severity of dysphonia in children born at < 25 weeks’ gestation. Ten individuals, aged between 9.67 and 17.08 years, presented for repeat assessment in a replication and extension of the original study. The mean period between assessments was 2.85 (SD 0.38) years. The primary outcome measure was the severity score on the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), with the Acoustic Voice Quality Index score as the secondary outcome measure. Scores on the Pediatric Voice Handicap Index were also compared.Results. Perceptual dysphonia severity scores were significantly lower on repeat assessment, but no differences were observed in objective or quality of life scores. Individual variation was observed: the difference in CAPE-V scores ranged from –36 to + 1. No participant presented with normal voice quality on repeat assessment.Discussion. Analysis of group data masked individual variability in this series. Mechanisms underlying such individual variation are currently unknown. These data suggest that dysphonia is persistent in extremely preterm children.Conclusion. Further investigation is warranted to elucidate the progression of voice disorders in extremely preterm children, to inform prognostic predictors and treatment decisions.

Long‐term effects of injection laryngoplasty with a temporary agent on voice quality and vocal fold position

Patients with unilateral vocal fold paralysis (UVFP) treated with temporary injection laryngoplasty (IL) have a decreased rate of permanent medialization laryngoplasty (ML) compared to UVFP patients initially treated by observation. The aim of this study was to determine whether the lower rate of ML corresponded with improved quantifiable measures. Retrospective review. Examinations at presentation and follow-up of 14 IL patients and 24 observation patients were analyzed for laryngoscopic features and Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) scores. The groups were similar at presentation. At follow-up, the IL group showed significant improvement in 11/18 laryngoscopic criteria and 7/12 CAPE-V parameters compared to the observation group (P < .05). The observation group underwent ML more frequently than the IL group (75% vs. 29%, P = .008). The lower rate of permanent ML in patients undergoing temporary IL corresponds with improvements in CAPE-V scores and laryngoscopic features. Improvements persisted beyond the accepted time frame for temporary graft resorption.

Laryngeal synovial cell sarcoma in an 11 year old boy: Challenges of management and rehabilitation

Despite the fact that vocal nodules are the most common cause of chronic dysphonia in children, uncertainty and lack of consensus complicates practically every diagnostic and management decision. Selecting an optimal staging system is fundamental to understanding a disease process, mandatory for uniform reporting, and crucial to predicting natural history and treatment outcomes.

Comparison of the Pediatric Voice Handicap Index With Perceptual Voice Analysis in Pediatric Patients With Vocal Fold Lesions

To compare a subjective patient/family-derived voice handicap survey with an expert observer-derived method of evaluating voice disturbance in pediatric patients with vocal fold lesions (VFLs). Retrospective review. Tertiary care referral center. Thirty-eight children with VFLs referred for voice evaluation. Pediatric Voice Handicap Index (pVHI) scores and Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) scores. Percentages for CAPE-V (100-point scale) and pVHI (92-point scale) were calculated for direct comparisons. Relationships between pVHI scores and CAPE-V scores were investigated using the Spearman rank correlation. Thirty-eight patients with VFLs (median age, 8.3 years; age range, 4.2-17.2 years; 63% males) were included from a database of more than 600 children and evaluated between November 15, 2005, and June 15, 2010. The median CAPE-V overall score was 30.3 (range, 1-67), and the normalized total pVHI score was 29.3 (range, 0-73) (P=.90). The Spearman rank correlation showed significant fair correlations between CAPE-V overall and functional pVHI and between CAPE-V strain and breathiness, and the pVHI total, functional, but none higher than ρ=0.44 (P≤.03). The correlation was higher in males for CAPE-V loudness to total pVHI (ρ=0.40, P=.04) and in females for CAPE-V breathiness (ρ=0.58, P=.03) and strain (ρ=0.55, P=.04) to total pVHI. The CAPE-V and the pVHI are useful tools in the measurement of voice outcomes in children with VFLs. There are fair correlations between the CAPE-V and the pVHI, and they likely evaluate important yet different aspects of voice disturbance. Significant gender differences in these correlations should be further evaluated in future studies.

Voice outcomes following adult cricotracheal resection

Cricotracheal resection (CTR) is an effective treatment for moderate-to-severe laryngotracheal stenosis (LTS) in adults. However, one of the potentially significant sequela of this procedure is postoperative dysphonia and permanent voice alteration. The objective of this study is to characterize voice changes in adult patients with subglottic stenosis who have undergone CTR. Retrospective case-series. Acoustic, aerodynamic, and consensus auditory-perceptual evaluation of voice (CAPE-V) data were reviewed for consecutive adult patients undergoing CTR and perioperative voice evaluation from 2000 to 2010. Sixteen patients (median age 44 years, 94% female) underwent CTR and voice evaluation during the study period. Thirteen patients underwent postoperative evaluation and had a mean overall CAPE-V score of 47.5/100, mean fundamental frequency (F0) of 156.7 Hz, average estimated subglottic pressure of 10.0 cm H(2) O, and an average airflow of 224 mL/sec. Seven patients underwent pre- and postoperative evaluations and had a significant reduction in mean F0 (206.5 vs. 151.1 Hz, P = .002) and mean F0 for connected speech (194.9 vs. 152.7 Hz, P = .047), but not in median intensity, range, estimated subglottic pressure, or airflow. Median overall CAPE-V scores worsened, but did not reach statistical significance (12 vs. 61.5, P = .28). Seventy-one percent of patients underwent an increase in acoustic signal typing postoperatively. Although CTR is an effective treatment for adult LTS, it results in significant alteration of the adult voice. In particular, CTR decreases the fundamental frequency of connected speech and vowel phonation and changes the acoustic signal type. Patients should be counseled about these likely voice alterations prior to undergoing surgery.

Comparison of Pediatric Voice Handicap Index Scores with Perceptual Voice Analysis in Patients following Airway Reconstruction

We performed a retrospective review to compare a subjective parental proxy-derived voice handicap survey to an observer-derived method of measuring voice perturbation in children who have undergone airway reconstruction. The main outcome measures were the Pediatric Voice Handicap Index (pVHI) total score and the Overall Severity score on the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). The percent Overall Severity CAPE-V score (score divided by 100) and the percent pVHI score (score divided by 92) were calculated. A Wilcoxon signed rank test was used to compare CAPE-V scores with the pVHI total scores. The relationship between the pVHI scores and the CAPE-V scores was investigated with a Spearman correlation. Subgroup analysis was performed to determine the relationship of surgery type to CAPE-V and pVHI scores. Fifty subjects with a history of airway surgery who were evaluated between 2005 and 2008 were identified. Forty-two of the 50 subjects had complete data for review. Their median age was 7.1 years (range, 3.3 to 17.9 years). Their pVHI total scores had a median of 30 (range, 1 to 80). Their Overall Severity CAPE-V scores had a median of 50.5 (range, 0 to 98). Their median CAPE-V percent was higher than their median pVHI percent (50.5% versus 32.6%; p = 0.0003). A weak correlation was found between the Overall Severity CAPE-V score and the pVHI total score (rho = 0.41; p = 0.0003). There was a trend toward higher Overall Severity CAPE-V scores in patients who underwent cricotracheal resection. The total number of airway surgeries was significantly correlated with the Overall Severity CAPE-V score (rho = 0.6; p <0.0001) but not with the pVHI score. Children who undergo airway reconstruction often have a resulting voice disturbance that can affect their lives in multiple dimensions. The results of this study revealed a weak-to-fair correlation between the parent-reported pVHI total score and expert ratings of voice quality using the CAPE-V. In this patient population, both of these tools provided important information regarding the relationship of the severity of voice disturbance to its handicapping effects.
