Role of Unilateral Vocal Cord Palsy in Causing Recurrent Tracheobronchial Foreign Bodies.

ABSTRACT: Background: Foreign body (FB) aspiration in children is a frequent condition managed by ENT pediatric surgeons and pediatric pulmonologists. Methods: We present the case of a 20-months-old child who presented with three recurrent episodes of FB aspiration. Results: At the time of FB removal, an initial dynamic examination of the larynx revealed a unilateral vocal cord palsy (UVCP). Conclusion: For recurrent tracheobronchial FB inhalation, we recommend a systematic dynamic airway endoscopy.

Project description:ImportanceUnilateral vocal fold paralysis (UVFP) is a common and life-changing complication of cancer, trauma, and an estimated 500 000 head, neck, and chest surgeries performed annually in the US, among other causes (eg, idiopathic). Consequent disabilities are profound and often permanent and can include severe voice, swallowing, and breathing dysfunction and concomitant anxiety, isolation, and fear. Physiological measures often correlate poorly with patient-reported disability. The measure described herein was designed to be a comprehensive, psychometrically sound UVFP-specific patient-reported outcome measure (PROM) for use in clinical trials or at point of care.ObjectiveTo evaluate the reliability and validity of the CoPE (vocal Cord Paralysis Experience) PROM in a nationally representative sample for both clinical and research use.Design, setting, and participantsThis survey validation study was performed at 34 tertiary care centers across the US and included English-speaking adults with unilateral vocal fold immobility confirmed via laryngoscopy.Main outcomes and measuresReliability (internal consistency, alternate form, and test-retest) and validity (convergent and known-group).ResultsIn total, 613 patients (mean [SD] age, 58 [15.3] years; 394 [64.5%] women) were recruited, and 555 (92.3%) completed surveys for all time points. Internal consistency was high in the overall 22-item PROM and psychosocial, swallow, and voice subscales (Cronbach α > 0.91). Intraclass correlations for individuals between the baseline and 2-week administrations were moderate for the overall score and subscales (intraclass correlations range, 0.66-0.80). There were significant differences between the online and 2-week paper administrations for the overall score and voice and psychosocial subscales (overall scale mean: 54.4 [95% CI, 49.7-59.1] vs 48.9 [95% CI, 43.7-54.0] at 2 weeks). The confirmatory model was found to be suitably fitted based on average r2 values 0.5 or greater for subscale and overall scores. Correlations between subscales and existing PROMs (Voice-Related Quality of Life, Eating Assessment Tool, and Communication Participation Item Bank) were all greater than 0.69, and mean PROM subscale scores were significantly different across known quartiles of existing PROMs.Conclusions and relevanceThe findings of this survey validation study suggest that the CoPE PROM could serve as a psychometrically sound, comprehensive measure of UVFP-attributed disability suitable for use in clinical and research settings to assess within-person changes. The results will inform a user manual to facilitate use in clinical trials comparing the effectiveness and durability of treatments including behavioral (speech therapy), temporary (eg, injection augmentation), and permanent surgical treatments for UVFP.

Project description:ImportanceEndotracheal intubation and mechanical ventilation are life-saving treatments for acute respiratory failure but are complicated by significant rates of dyspnea and dysphonia after extubation. Unilateral vocal fold immobility (UVFI) after extubation can alter respiration and phonation, but its incidence, risk factors, and pathophysiology remain unclear.ObjectivesTo determine the incidence of UVFI after prolonged (>12 hours) mechanical ventilation in a medical intensive care unit and investigate associated clinical risk factors for UVFI after prolonged mechanical ventilation.Design, setting, and participantsThis subgroup analysis of a prospective cohort study was conducted in a single-center medical intensive care unit from August 17, 2017, through May 31, 2018, among 100 consecutive adult patients who were intubated for more than 12 hours. Patients were identified within 36 hours of extubation and recruited for study enrollment. Those with an established tracheostomy prior to mechanical ventilation, known laryngeal or tracheal pathologic characteristics, or a history of head and neck radiotherapy were excluded.ExposureInvasive mechanical ventilation via an endotracheal tube.Main outcomes and measuresThe incidence of UVFI as determined by flexible nasolaryngoscopy.ResultsOne hundred patients (62 men [62%]; median age, 58.5 years [range, 19.0-87.0 years]) underwent endoscopic evaluation after extubation. Seven patients had UVFI, of which 6 cases (86%) were left sided. Patients with hypotension while intubated (odds ratio [OR], 10.8; 95% CI, 1.6 to ∞), patients requiring vasopressors while intubated (OR, 16.7; 95% CI, 2.4 to ∞), and patients with a preadmission diagnosis of peripheral vascular disease (OR, 6.2; 95% CI, 1.2-31.9) or coronary artery disease (OR, 5.1; 95% CI, 1.0-25.5) were more likely to develop UVFI.Conclusions and relevanceUnilateral vocal fold immobility occurred in 7 of 100 patients in the medical intensive care unit who were intubated for more than 12 hours. Unilateral vocal fold immobility was associated with inpatient hypotension and preadmission vascular disease, suggesting that ischemia of the recurrent laryngeal nerve may play a role in disease pathogenesis.
