A grading scale for pediatric vocal fold nodules

Short-Term Effects of Semi-Occluded Vocal Tract Therapy on the Phonation of Children With Vocal Fold Nodules: A Randomized Controlled Trial

PURPOSE

The aim was to determine and compare the short-term effects of two intensive semi-occluded vocal tract (SOVT) programs, "straw phonation" (SP) and "resonant voice therapy" (RVT), on the phonation of children with vocal fold nodules.

METHOD

A pretest-posttest randomized controlled study design was used. Thirty children aged 6-12 years were randomly assigned to the SP group (n = 11), RVT group (n = 11), or control group receiving indirect treatment (n = 8) for their voice problems. All participants received 11 hr of group voice therapy over four consecutive days. A multidimensional voice assessment consisting of both objective (dysphonia severity index and acoustic voice quality index) and subjective (pediatric voice handicap index and perceptual rating of overall severity) measures was performed pre- and posttherapy. Voice therapy effectiveness was evaluated using group-level analyses (linear mixed models) and individual-level analyses to investigate what proportion of participants changed to a clinically relevant degree.

RESULTS

Group-level analyses found no significant Time × Group interactions, indicating that the evolution over time did not differ among the three groups. Within-group effects of time showed a significant and equal improvement in dysphonia severity index in the SP and RVT groups and a significant improvement in perceptual rating of overall severity in the SP group. For dysphonia severity index, individual-level analyses showed that 36% and 45% of participants improved to a clinically relevant degree in the SP and RVT groups, respectively. For acoustic voice quality index, 38% improved to a clinically relevant degree in the SP group.

CONCLUSIONS

Results suggest that short-term intensive SOVT programs may have a positive effect on voice quality and vocal capacities of children with vocal fold nodules. Participants seem to benefit more from a SP program than a RVT program.

The Effect of An Indirect Voice Therapy Approach on the Voice of Children With Vocal Fold Nodules: A Prospective Cohort Study

PURPOSE

To investigate the effect of a combination indirect voice therapy approach on the management of vocal nodules in the pediatric population.

METHODS

A prospective cohort study with thirty children (24 males and 6 females; mean age 8.8 ± 2.2) with a diagnosis of vocal fold nodule (VFN) was conducted. All participants were included in an 8-week voice therapy program consisting of vocal hygiene education and parental rule-setting. Videolaryngoscopic examination, auditory-perceptual evaluation, and acoustic voice analysis were performed immediately before and after the intervention.

RESULTS

The comparison of videolaryngoscopic findings before and after the therapy revealed that the size of the nodules decreased significantly (P < 0.001). Findings from the laryngeal examination showed that the vast majority of children 73.3% (n = 22) had no VFN anymore after the intervention. The auditory-perceptual evaluation showed that overall severity of dysphonia decreased significantly [from 50 (40-70) to 38 (30-45), P < 0.001]. Jitter local (P = 0.031) and Jitter local abs (P = 0.043) parameters statistically differed after the therapy. There were not any statistically significant differences for mean F0, shimmer local (%), shimmer local (dB), and mean HNR.

CONCLUSIONS

The voice therapy method in this study has a clear benefit on the voice of children with VFN and can be used in clinical practice. Specifically, clinicians should consider the parents as a core component of voice therapies and pay attention to vocal hygiene education for optimal management of VFN related childhood dysphonia.

Efficacy and safety of acupuncture for vocal nodules: A systematic review and meta-analysis with trial sequential analysis

In this study, we aim to evaluate the efficacy and safety of acupuncture for vocal nodules, concerning qualitive overall efficacy and quantitative improvement on quality of voice. Four English and four Chinese databases were searched up to December 10th, 2022. Risk of bias among the included trials were evaluated by the Cochrane ROB tool. Systematic reviews and meta-analyses were conducted based on the Cochrane systematic review method by using RevMan 5.4 Software, and trial sequential analyses were performed by TSA 0.9. Meta-influence analyses, subgroup-analyses, meta-regression, and evaluation of publication bias were performed for exploration of heterogeneity by Stata V.14. Quality of the results was accessed through the GRADE-pro GDT. Cluster analyses and correlation coefficient were performed by R 4.1.3. Finally, 15 trials involving 1,888 participants were included. Results showed that compared with western medicine alone or Chinese herbal medicine alone, acupuncture alone yielded significantly (p<0.05) higher clinical effective rate and more improvement on scores of voice analyses. However, reduction on scores of grade, roughness, and breathiness and voice handicap index during follow-ups, and results of clinical effective rate suggested that acupuncture was inferior to voice training. In addition, meta-regression and sub-group analyses firstly revealed advanced efficacies of acupuncture when performed with local and remote acupoints, compared with local acupoints only. Acupuncture specified adverse event was denied in six trials while it was not mentioned in other nine trials. Results of cluster analyses and correlation coefficient showed that Kai yin yi hao and He gu (LI-4) were the most frequently applied matching-acupoints in trials. In conclusion, compared with western medicine (level of evidence: low ⨁⨁◯◯, GRADE C) and Chinese herbal medicine (level of evidence: moderate ⨁⨁⨁◯, GRADE B), acupuncture is safe and of better efficacy for patients with vocal nodules, while there is also need for RCTs with improvements on designing and interventions in experimental and controls.

Effects of voice therapy in children with vocal fold nodules: A systematic review

BACKGROUND

Vocal fold nodules (VFNs) are the main cause of paediatric dysphonia. Voice therapy is recommended as the preferable treatment option for VFNs in children.

AIM

The aim of this systematic review is to provide an overview of the existing literature concerning the effects of voice therapy in children with VFNs.

METHODS & PROCEDURES

This systematic literature review was developed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (via PubMed) and Embase were searched and the grey literature was checked. The search strategy was based on three concepts: VFNs, voice therapy and children. Two examiners independently determined article eligibility and extracted all relevant data from the included studies. The methodological quality of the included study was assessed using the QualSyst tool.

MAIN CONTRIBUTIONS

By identifying, evaluating and summarizing the results of all relevant studies about voice therapy in paediatric VFNs, this systematic review makes the available evidence more accessible to voice therapists, otolaryngologists and other relevant stakeholders.

CONCLUSIONS & IMPLICATIONS

24 studies were included in this systematic review. Eight studies (8/24) reported a significant improvement for at least one outcome parameter after voice therapy. However, five papers (5/24) could not demonstrate significant changes after voice therapy. All studies that did not test for significance (11/24) found improvements for one or more outcome parameters. The overall quality of the included studies is adequate (55%). In sum, there is some evidence that voice therapy is effective in children with VFNs, but further well-designed research, especially randomized controlled trials, is necessary to confirm these results.

WHAT THIS PAPER ADDS

What is already known on the subject Voice therapy is preferable in children with VFNs because of the phonotraumatic nature of the nodules and the associated high recurrence rate after phonosurgery. Most voice therapists in clinical practice offer an eclectic voice therapy programme, consisting of direct and indirect voice therapy techniques. What this study adds to existing knowledge This systematic review provides a clear overview of the available evidence concerning the effects of voice therapy in paediatric VFNs. There is some evidence that voice therapy is an effective treatment option in children with VFNs, but well-designed research is scarce on this subject. What are the potential or actual clinical implications of this work? This review shows that effectiveness studies with strong designs are very scarce in children with VFNs. Clinicians should be aware that few therapy techniques have been thoroughly investigated in this population. However, this review may guide voice therapists when creating a treatment plan for a child with VFNs because it identifies, evaluates and summarizes the results of all relevant individual studies about voice therapy in paediatric VFNs. Voice therapy seems to be effective in treating paediatric patients with VFNs, given the fact that a considerable number of included studies report significant improvements after voice therapy. Both direct and indirect therapy approaches appear to have a positive effect on the phonation of children with VFNs.

Vocal nodules in children: Laryngoscopic morphological classification aids prognostic judgment

OBJECTIVE

Vocal fold nodules (VFNs) are benign lesions, occurring at the junction of the anterior and middle thirds of bilateral vocal cords, for which pediatric prognosis and treatment remains controversial. There is a requirement for a correlation indicator to assess the prognosis by pediatric otolaryngologists.

MATERIALS AND METHODS

Patients with VFNs, who were admitted to the department of otolaryngology, were enrolled. The patient's gender, age, duration of dysphonia, laryngoscopy results and related diseases [allergic rhinitis, sinusitis, laryngopharyngeal reflux (LPR)] were collected and recovery from dysphonia followed up. Correlations between clinical factors and type of laryngoscopic morphology of VFNs were analyzed.

RESULTS

A total of 432 patients with dysphonia were identified, 208 agreed to undergo laryngoscopy and 194 were diagnosed with VFNs as a result. The modal age of patients with dysphonia was between 3 and 7 years with a male: female ratio of 2.1:1 (294:138) and 116 (26.85%; 116/432) had symptoms of allergic rhinitis. The boy to girl ratio among the 194 children with VFNs was about 2.6:1 (140:54) and modal age was consistent with dysphonia. Vocal nodules were the cause of most phonation disorders (93.27%; 194/208) and those with long duration of dysphonia presented more mature (p = 0.026) and discrete types (p = 0.022). Boys were more likely to have mature (p = 0.050) and discrete nodules (p = 0.008). Dysphonia recovery time was closely related to age (p = 0.000), duration of dysphonia (p = 0.000) and morphology of vocal nodules under laryngoscopy (p = 0.000).

CONCLUSION

Vocal nodules are the most frequent cause of phonation disorders in children. The morphological classification by endoscopy may help with clinical diagnosis and therapy choice. In the case of the older child with longer duration of dysphonia and the appearance of mature, large, discrete nodules by laryngoscopy, active treatment is recommended, such as drug therapy, voice therapy or surgical treatment.

Pediatric dysphonia: It's not about the nodules

OBJECTIVE

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. 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.

METHODS

Seventy-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.

RESULTS

Based 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).

CONCLUSION

The 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.

Indirect vs Direct Voice Therapy for Children With Vocal Nodules: A Randomized Clinical Trial

Importance

Benign vocal fold nodules affect 12% to 22% of the pediatric population, and 95% of otolaryngologists recommend voice therapy as treatment. However, no randomized clinical trials that we are aware of have shown its benefits.

Objective

To determine the impact of voice therapy in children with vocal fold nodules according to pretherapy and posttherapy scores on the Pediatric Voice-Related Quality of Life (PVRQOL) survey; secondary objectives included changes in phonatory parameters.

Design, Setting, and Participants

For this multicenter randomized clinical trial, 114 children ages 6 to 10 years with vocal fold nodules, PVRQOL scores less than 87.5, and dysphonia for longer than 12 weeks were recruited from outpatient voice and speech clinics. This age range was identified because these patients have not experienced pubertal changes of the larynx, tolerate stroboscopy, and cooperate with voice therapy. Participants were blinded to treatment arm.

Interventions

Participants received either indirect or direct therapy for 8 to 12 weeks. Indirect therapy focused on education and discussion of voice principles, while direct treatment used the stimulus, response, antecedent paradigm.

Main Outcomes and Measures

The primary outcome measure was PVRQOL score change before and after treatment. Secondary phonatory measures were also compared.

Results

Overall, 114 children were recruited for study (mean [SD] age, 8 [1.4] years; 83 males [73%]); with 57 randomized to receive either indirect or direct therapy. Both direct and indirect therapy approaches showed significant differences in PVRQOL scores pretherapy to posttherapy. The mean increase in PVRQOL score for direct therapy was 19.2, and 14.7 for indirect therapy (difference, 4.5; 95.3% CI, -10.8 to 19.8). Of 44 participants in the direct therapy group, 27 (61%) achieved a clinically meaningful PVRQOL improvement, compared with 26 of 49 (53%) for indirect therapy (difference, 8%; 95% CI, -12 to 28). Post hoc stratification showed robust effects in the direct therapy group for older children (Cohen d = 0.50) and the latter two-thirds of participants (Cohen d = 0.46). Vocal fold nodules reduced in size in 31% (22 of 70) and completely resolved in 11% (8 of 70) of participants who consented to a second set of images after going through the recruitment process.

Conclusions and Relevance

Both direct and indirect voice therapy improved voice-related quality of life in children with vocal fold nodules, although there was no significant difference between approaches. Future studies may focus upon which voice therapy approaches are effective in treating age-defined populations.

Electroglottographic and acoustic analysis of voice in children with vocal nodules

PURPOSE

Vocal fold nodules are usually caused by voice overuse or vocal hyperfunction, and their symptoms include persistent hoarseness - a disturbance in the vocal fold vibrations which results in a turbulent passage of air in the glottis, manifested as a raspy, rough voice. The aim of the study was to present data concerning voice quality in patients with vocal nodules and to compare electroglottographic analysis (EGG) with acoustic analysis.

METHODS

The study examined 57 children with vocal fold nodules (Group 1). Each patient underwent a phoniatric evaluation of the vocal tract, a videolaryngoscopic examination, and a voice quality assessment, employing electroglottographic and acoustic analyses. The control group consisted of 37 healthy children (Group 2). The following parameters were analyzed: Closed Quotient (EGG signal), Peak Slope, Normalized Amplitude Quotient and Cepstral Peak Prominence (acoustic signal - waveform).

RESULTS

Changes in the EGG signal could be detected in 95% of the patients with vocal nodules, indicating the occurrence of vocal nodules and glottal insufficiency. The acoustic analysis confirmed breathy phonation in 63% of the patients. The Closed Quotient parameter proved to be more effective than Peak Slope. Closed Quotient, Peak Slope and Normalized Amplitude Quotient allowed for the differentiation of the EGG signal and the acoustic signal in groups 1 and 2 in a statistically significant way.

CONCLUSIONS

The results of electroglottographic and acoustic analysis show incorrect voice parameters in patients with vocal nodules with reference to the control group. At the same time, the EGG analysis proved to be more effective than the analysis of the acoustic signal.

Clinical and surgical implications of intraoperative optical coherence tomography imaging for benign pediatric vocal fold lesions

INTRODUCTION

Benign vocal disorders in children include an extensive list of abnormalities creating a variety of debilitating levels of dysphonia. Precise delineation of the benign lesion type and margins may have significant public health implications in children. An innovative technology such as optical coherence tomography (OCT) is being explored to delineate pediatric benign laryngeal lesions. An accurate assessment of the subepithelial morphology may help towards tailoring more personalized therapeutic treatments. This study was established to highlight key morphological and optical features of benign pediatric laryngeal lesions using intraoperative OCT and to suggest clinical implications that arise from such optical imaging.

METHODS AND MATERIALS

This in vivo study was performed at Massachusetts Eye and Ear Infirmary. Intraoperative imaging was performed on twenty-five pediatric patients ranging from 1 year to 16 years of age presenting hoarseness. Three-dimensional OCT images of benign laryngeal lesions or a subsite of the lesion were acquired.

RESULTS

High-resolution OCT images of 25 patients with benign laryngeal lesions such as nodules, cysts, Reinke's edema, vocalis sulcus, and papilloma revealed distinct and specific morphological differences with normal tissue. Nodules show a symmetrical superficial remodeling of the vocal fold epithelial layer and the basement membrane. Cysts have oval-like shape and are either superficial or deeply located in the lamina propria. Sulcus vocalis OCT imaging allows characterizing if the lesion is shallow or deep according to Ford's classification system. Reinke's edema of the mucosa can be observed and quantified, which may lead to suspicion on the underlying social and medical conditions. Finally, the ability to assess margins and depth of invasion of papilloma lesions is demonstrated, raising the possibility to use OCT with angiolytic lasers for patient-tailored treatments.

CONCLUSIONS

OCT imaging of benign pediatric vocal lesions is promising as it could improve preoperative decision-making and possibly peroperative imaging-guidance for patient-tailored treatments. An assessment of the optical contrast between healthy and abnormal tissue may help towards a more qualitative and quantitative approach to current standard care, especially when diagnosis remains unclear.

Adaptation and validation of Mandarin Chinese version of the pediatric Voice Handicap Index (pVHI)

OBJECTIVE

The aim of this study was to adapt and validate the English version of pediatric voice handicap index (pVHI) into Mandarin Chinese.
 METHODS: A cross-sectional study was performed from May 2016 to April 2017. A total of 367 parents participated in this study, and 338 parents completed the translated questionnaire without missing data, including 213 parents of children with voice disorders (patients group), and 125 parents of children without voice disorders (control group). The internal consistency, test-retest reliability, contents validity, construct validity, clinical validity, and cutoff point were calculated.

RESULTS

The most common voice disorder in the patients group was vocal fold nodules (77.9%), followed by chronic laryngitis (18.8%), and vocal fold polyps (3.3%). The prevalence for voice disorders was higher in boys (67.1%) than girls (32.9%). The most common vocal misuse and abuse habit was shouting loudly (n = 186, 87.3%), followed by speaking for a long time (n = 158, 74.2%), and crying loudly (n = 99, 46.5%). The internal consistency for the Mandarin Chinese version of pVHI was excellent in patients group (Cronbach α = 0.95). The inter-class correlation coefficient indicated strong test-retest reliability (ICC = 0.99). The principal-component analysis demonstrated three-factor eigenvalues greater than 1, and the cumulative proportion was 66.23%. The mean total scores and mean subscales scores were significantly higher in the patients group than the control group (p < 0.05). The physical domain had the highest mean score among the three subscales (functional, physical and emotional) in the patients group. The optimal cutoff point of the Mandarin Chinese version of pVHI was 9.5 points with a sensitivity of 80.3% and a specificity of 84.8%.

CONCLUSION

The Mandarin Chinese version of pVHI was a reliable and valid tool to assess the parents' perception about their children's voice disorders. It is recommended that it can be used as a screening tool for discriminating between children with and without dysphonia.

Correlation of Vocal Fold Nodule Size in Children and Perceptual Assessment of Voice Quality

Objectives

We examined the relationship between the size of vocal fold nodules and perceptual rating of voice quality in children.

Methods

We carried out an Institutional Review Board-approved retrospective study in a voice clinic within a tertiary-care pediatric medical center. We studied children seen between 2000 and 2009 with a primary diagnosis of vocal fold nodules as the cause of their voice disturbance. Pediatric vocal fold nodule size was rated with a published validated scale, and voice quality was rated on the Consensus Auditory-Perceptual Evaluation of Voice scale.

Results

One hundred forty-five patients met the inclusion criteria. Small nodules were noted in 23% of patients, medium nodules in 39%, and large nodules in 37%. Univariate and multivariate analyses demonstrated a statistically significant relationship (p < 0.05) between vocal fold nodule size and rated perceptual qualities of overall severity of voice disturbance, roughness, strain, pitch, and loudness. With the exception of loudness, as vocal fold nodule size increased, the mean value of perceptual characteristics became larger. The age of the patient was a significant factor associated with the overall severity of the voice disturbance and roughness.

Conclusions

The overall severity of a child's voice disturbance and qualities of roughness, strain, pitch, and loudness have a strong correlational relationship with pediatric vocal fold nodule size, which is suggestive of causality.

Feasibility of Clinical Endoscopy and Stroboscopy in Children With Bilateral Vocal Fold Lesions

PURPOSE

The purpose of this study was to examine the utility of flexible and rigid endoscopy and stroboscopy for the identification of anatomical and physiological features in children with bilateral vocal fold lesions. The secondary purpose was to describe the age distribution of patients who could tolerate use of the different types of endoscopes.

METHOD

This cross-sectional clinic-based study included 38 children (ages 5 to 12 years) diagnosed with bilateral vocal fold lesions via videoendoscopy. Vocal fold vibratory characteristics (e.g., mucosal wave) were rated by 4 clinicians by consensus.

RESULTS

Bilateral vocal fold lesions could be well described anatomically after visualization with both flexible and rigid endoscopes and were most commonly described as symmetrical and broad based. However, the clinicians' confidence in the accuracy of stroboscopy for rating vocal fold vibratory characteristics was limited for both flexible and rigid stroboscopes.

CONCLUSIONS

Videoendoscopy was adequate for viewing and characterizing anatomical structures of bilateral vocal fold lesions in pediatric patients; however, vibratory characteristics were often not fully visualized with videostroboscopy. In view of the importance of visualizing vocal fold vibration in the differential diagnosis and treatment of vocal fold lesions, other imaging modalities, such as high-speed videoendoscopy, may provide more accurate descriptions of vocal fold vibratory characteristics in this population.

Validation of a Pediatric Vocal Fold Nodule Rating Scale Based on Digital Video Images

Objectives:

We sought to create a validated scale of vocal fold nodules in children, based on digital video clips obtained during diagnostic fiberoptic laryngoscopy.

Methods:

We developed a 4-point grading scale of vocal fold nodules in children, based upon short digital video clips. A tutorial for use of the scale, including schematic drawings of nodules, static images, and 10-second video clips, was presented to 36 clinicians with various levels of experience. The clinicians then reviewed 40 short digital video samples from pediatric patients evaluated in a voice clinic and rated the nodule size. Statistical analysis of the ratings provided inter-rater reliability scores.

Results:

Thirty-six clinicians with various levels of experience rated a total of 40 short video clips. The ratings of experienced raters (14 pediatric otolaryngology attending physicians and pediatric otolaryngology fellows) were compared with those of inexperienced raters (22 nurses, medical students, otolaryngology residents, physician assistants, and pediatric speech-language pathologists). The overall intraclass correlation coefficient for the ratings of nodule size was quite good (0.62; 95% confidence interval, 0.52 to 0.74). The p value for experienced raters versus inexperienced raters was 0.1345, indicating no statistically significant difference in the ratings by these two groups. The intraclass correlation coefficient for intra-rater reliability was very high (0.89).

Conclusions:

The use of a dynamic scale of pediatric vocal fold nodule size most realistically represents the clinical assessment of nodules during an office visit. The results of this study show a high level of agreement between experienced and inexperienced raters. This scale can be used with a high level of reliability by clinicians with various levels of experience. A validated grading scale will help to assess long-term outcomes of pediatric patients with vocal fold nodules.

A conscious sedation protocol for videolaryngostroboscopy in pediatric patients

Objective. To determine best sedation protocol for videolaryngostroboscopy in children unable to tolerate non-sedated evaluation. Materials and Methods. Consecutive case series of 10 children with voice disturbances, unable to tolerate nonsedated videolaryngostroboscopy at an academic tertiary care children's hospital. Flexible fiberoptic videolaryngostroboscopy was performed and interpreted by pediatric otolaryngologist and speech and language pathologist. Sedation was administered with newly described protocol that allowed functional portion of evaluation.

MAIN OUTCOME MEASURES

ability to follow commands and tolerate flexible fiberoptic videolaryngostroboscopy.

SECONDARY OUTCOME MEASURES

total phonation time, complications, need for subsequent videolaryngostroboscopic attempts, clinical outcomes, and follow-up. Results. 10 children underwent procedure under conscious sedation. 9/10 children were able to perform simple tasks and maintain adequate phonation time to complete stroboscopic exam. 1/10 patients failed to complete exam because of crying during entire exam. Mean exam time was 2 minutes 52 seconds (SD 86 seconds), phonation time is 1 minute 44 seconds (SD 60 seconds), and number of tasks completed was 10.5 (SD 8.6). Conclusions. Conscious sedation for videolaryngostroboscopy can be safely and effectively performed in children unable to comply with nonsedated examination. Such studies provide valuable diagnostic information to make a diagnosis and to devise a treatment plan.
