OBJECTIVES/HYPOTHESIS To critically review current literature comparing interventional approaches for unilateral vocal fold paralysis. STUDY DESIGN Systematic review of the literature. METHODS All English-language literature published in the PubMed database was eligible for inclusion. Inclusion criteria were: 1) the major topic must be a direct comparison of outcomes in interventions for un...

RATIONALE Recurrent laryngeal nerve block is an uncommon complication that can occur after an interscalene brachial plexus block (ISB), which may lead to vocal cord palsy or paresis. However, if the recurrent laryngeal nerve is blocked in patients with a preexisting contralateral vocal cord palsy following neck surgery, this may lead to devastating acute respiratory failure. Thus, ISB is contra...

First reported by Nager in 1927, unilateral vocal cord paralysis associated with thyroid disease suggests the malignant and irreversible nature of the thyroid lesion. This condition is rarely seen in benign thyroid diseases, and the function of the vocal cord does not usually return. We present a 54-year-old woman with a history of right hemithyroidectomy for benign thyroid nodule, who had an e...

SUMMARY Left vocal cord paralysis in association with patent ductus arteriosus is unusual. We report a patient with long-standing patent ductus arteriosus (PDA) in whom CT studies obtained before and after paralysis developed showed an interval increase in size of the pulmonary trunk. The pathogenesis of left vocal cord paralysis in association with long-standing PDA is discussed.

There are a variety of methods for treating unilateral vocal cord paralysis, but to date there have been few studies that compare these phonosurgical techniques by using objective measures of voice improvement. Vocal efficiency is an objective voice measure that is defined as the ratio of the acoustic power produced by the larynx to the subglottic air power. Vocal efficiency has been found to d...

UNLABELLED Vocal cord paralysis (VCP) can be caused by any process that interferes with the normal function of the vagal nerves or recurrent laryngeal nerves. It may be a first sign of extensive and severe pathology. Radiologists must therefore be able to recognise the imaging findings of VCP and know the course of the vagal and recurrent laryngeal nerves. This review focuses on the anatomy and...
