Pediatric Vocal Fold Paresis and Paralysis: A Narrative Review.

JAMA Otolaryngol Head Neck Surg 2021 Jun 10. Epub 2021 Jun 10.

School of Communication Sciences and Disorders, McGill University, Montreal, Canada.

Importance: Vocal fold paralysis (VFP) results from the disruption of neural motor outputs to laryngeal muscles. Children with VFP manifest various degrees of difficulties in phonation, breathing, and swallowing. Although the etiologic characteristics and symptoms of VFP are well established in adults, corresponding clinical profiles are notably different in children. Clinical management of VFP is particularly challenging in children because their larynges are still actively developing and the recovery of disrupted laryngeal nerves is often unpredictable. This review discusses the neurologic conditions and diagnostic and treatment considerations in pediatric VFP.

Observations: Injury to the peripheral laryngeal nerves and certain central nervous system diseases, such as Arnold-Chiari malformation type II, can result in VFP in infants and children. The incidence of unilateral vs bilateral VFP is variable across pediatric studies. Most reported VFP cases are associated with injury of the recurrent laryngeal nerve. Laryngeal electromyography requires needle insertion that must be performed under anesthesia with special care in the pediatric setting. Neither normative values nor standardized procedures of laryngeal electromyography are currently established for the pediatric population. Laryngeal reinnervation, endoscopic arytenoid abduction lateropexy, and laryngeal pacing are plausible treatment options for pediatric VFP. Despite these new advances in the field, no corresponding efficacy data are available for clinicians to discern which type of patients would be the best candidates for these procedures.

Conclusions And Relevance: The neuroanatomy and neurophysiology of VFP remain more elusive for the pediatric population than for adults. Basic and clinical research is warranted to fully comprehend the complexity of this laryngeal movement disorder and to better inform and standardize clinical practice.

Investigation of Vocal Fatigue Using a Dose-Based Vocal Loading Task.

Appl Sci (Basel) 2020 Feb 10;10(3). Epub 2020 Feb 10.

Department of Mechanical Engineering, McGill University, Montreal, QC H3A 0C3, Canada.

Vocal loading tasks are often used to investigate the relationship between voice use and vocal fatigue in laboratory settings. The present study investigated the concept of a novel quantitative dose-based vocal loading task for vocal fatigue evaluation. Ten female subjects participated in the study. Voice use was monitored and quantified using an online vocal distance dose calculator during six consecutive 30-min long sessions. Voice quality was evaluated subjectively using the CAPE-V and SAVRa before, between, and after each vocal loading task session. Fatigue-indicative symptoms, such as cough, swallowing, and voice clearance, were recorded. Statistical analysis of the results showed that the overall severity, the roughness, and the strain ratings obtained from CAPE-V obeyed similar trends as the three ratings from the SAVRa. These metrics increased over the first two thirds of the sessions to reach a maximum, and then decreased slightly near the session end. Quantitative metrics obtained from surface neck accelerometer signals were found to obey similar trends. The results consistently showed that an initial adjustment of voice quality was followed by vocal saturation, supporting the effectiveness of the proposed loading task.

Eliciting ERP Components for Morphosyntactic Agreement Mismatches in Perfectly Grammatical Sentences.

The present event-related brain potential (ERP) study investigates mechanisms underlying the processing of morphosyntactic information during real-time auditory sentence comprehension in French. Employing an auditory-visual sentence-picture matching paradigm, we investigated two types of anomalies using entirely grammatical auditory stimuli: (i) semantic mismatches between visually presented actions and spoken verbs, and (ii) number mismatches between visually presented agents and corresponding morphosyntactic number markers in the spoken sentences (determiners, pronouns in liaison contexts, and verb-final "inflection"). We varied the type and amount of number cues available in each sentence using two manipulations. First, we manipulated the verb type, by using verbs whose number cue was audible through subject (clitic) pronoun liaison (liaison verbs) as well as verbs whose number cue was audible on the verb ending (consonant-final verbs). Second, we manipulated the pre-verbal context: each sentence was preceded either by a neutral context providing no number cue, or by a subject noun phrase containing a subject number cue on the determiner. Twenty-two French-speaking adults participated in the experiment. While sentence judgment accuracy was high, participants' ERP responses were modulated by the type of mismatch encountered. Lexico-semantic mismatches on the verb elicited the expected N400 and additional negativities. Determiner number mismatches elicited early anterior negativities, N400s and P600s. Verb number mismatches elicited biphasic N400-P600 patterns. However, pronoun + verb liaison mismatches yielded this pattern only in the plural, while consonant-final changes did so in the singular and the plural. Furthermore, an additional sustained frontal negativity was observed in two of the four verb mismatch conditions: plural liaison and singular consonant-final forms. This study highlights the different contributions of number cues in oral language processing and is the first to investigate whether auditory-visual mismatches can elicit errors reminiscent of outright grammatical errors. Our results emphasize that neurocognitive mechanisms underlying number agreement in French are modulated by the type of cue that is used to identify auditory-visual mismatches.
