“…Both theories may partially explain why the correlation between clinician‐rated and patient‐reported voice quality is modest . Surgical intervention for UVFP often restores voice quality to a satisfactory rating based on clinician‐centric instruments and objective acoustical measures, yet certain treated patients are somewhat dissatisfied despite “successful” surgical intervention …”

Vocal motor control and central auditory impairments in unilateral vocal fold paralysis

Objectives To evaluate differences in vocal motor control and central auditory processing between treated unilateral vocal fold paralysis (UVFP) and healthy control cohorts. Study Design Cross‐sectional. Methods Ten UVFP study patients treated by type I thyroplasty with stable voices were compared to 12 control subjects for vocal motor control using a pitch perturbation response task and central auditory processing performance using a battery of complex sound intelligibility assays that included adverse temporal and noise conditions. Standard clinical evaluations of voice production and peripheral audiometric sensitivity were performed. Results Vocal motor control was impaired in treated UVFP. The UVFP cohort exhibited a 32.5% reduction in the instantaneous, subconscious compensatory response to pitch feedback perturbation in the interval between 150 ms and 550 ms following onset (P < 0.0001, linear mixed effects model). This impairment cannot simply be ascribed to vocal motor capacity insufficiency in the UVFP cohort because both cohorts demonstrated comparable functional capacity to perform the vocal motor task. The UVFP cohort also showed greater propensity for central auditory processing impairment (P < 0.05), notably for temporal compression and added noise challenges. Conclusion Combined central vocal motor control and auditory processing impairments in treated UVFP highlight reciprocal interdependency of sensory and motor systems. This pilot study suggests that peripheral motor impairment of the larynx can degrade central auditory processing, which in turn may contribute to vocal motor control impairment. A more complete restoration communicative function in UVFP will require deeper understanding of sensory, motor, and sensorimotor aspects of the human communication loop.

Objectives/Hypothesis To evaluate differences in cortical‐basal ganglia‐cerebellar functional connectivity between treated unilateral vocal fold paralysis (UVFP) and healthy control cohorts using resting‐state functional magnetic resonance imaging (RS‐fMRI). Study Design Cross‐sectional. Methods Ten UVFP study patients treated by type I thyroplasty and 12 control subjects underwent RS‐fMRI on a 3‐Tesla scanner to evaluate differences in functional connectivity of whole‐brain networks. Spontaneous RS‐fMRI data were collected using a gradient echo planar pulse sequence, preprocessed, and analyzed to compare seed‐to‐voxel maps between the two cohorts. Seeds were placed in the caudate, putamen, and globus pallidus divisions of the basal ganglia in both hemispheres. Group contrasts were tested for statistical significance using two‐tailed unpaired t tests corrected for multiple comparisons with a cluster false discovery rate threshold of P < .05. Results UVFP patients demonstrated increased connectivity between both caudate nuclei and the precuneus, a node of the default mode network, compared to healthy controls. Both caudate nuclei also showed decreased connectivity with the left cerebellar hemisphere. The putamen and globus pallidus divisions of the basal ganglia were not abnormally connected to other brain structures. Conclusions UVFP patients treated by type I thyroplasty exhibited long‐term alterations of cortical‐basal ganglia‐cerebellar networks thought to be important for self‐referential voice quality awareness and learning processes that compensate for changes to the paralyzed hemilarynx. This pilot study on relatively small cohorts adds to growing evidence for persistent central nervous system changes in treated UVFP. Replication studies with larger numbers of subjects will be essential to validate and extend findings. Level of Evidence 3b Laryngoscope, 130:460–464, 2020

ObjectiveType 1 Thyroplasty is a well‐established procedure used for medializing an immobile vocal fold. Silastic and Gore‐Tex are the two most common materials used to accomplish this, but comparative data on their relative efficacy are scarce. We sought to compare outcomes between Silastic and Gore‐Tex implants via systematic review and meta‐analysis for unilateral vocal fold immobility.MethodsWe collected available data from PubMed, Embase, and Web of Science on demographics, maximum phonation time (MPT), voice handicap index (VHI‐10/30) score, and any other relevant metrics encountered before comparatively evaluating differences in outcomes.ResultsThe search yielded 1,534 records with 55 manuscripts ultimately included. There were 41 unique studies that utilized Silastic for a total of 1038 patients. There were 13 unique studies that utilized Gore‐Tex for a total of 245 patients. The pooled mean increase in MPT for Silastic patients was 7.8 s (+1.3 SMD) compared with 5.7 s for Gore‐Tex (+1.6 SMD). There was significant publication bias present in both analyses. The pooled mean change in VHI‐30 with Silastic was −45.4 (62.2%, −2.09 SMD) compared with −51.6 (73.5%, −1.1 SMD) with Gore‐Tex. The pooled mean change in VHI‐10 with Silastic was −15.6 (54%, −0.46 SMD) compared with −11.6 (43%, −0.86 SMD) with Gore‐Tex. There was no significant publication bias present in VHI outcomes.ConclusionsSilicone and Gore‐Tex implants provide adequate and comparable results in TT1. The data supporting this conclusion are limited by follow‐up, diversity in outcomes, limited data availability, and publication bias. Future research should be dedicated to comparing implants in a well‐randomized environment. Laryngoscope, 2024
