#1
H Gurbuz Aytuluk, O Aktas
Cranial nerve palsy is a rare neurological complication of epidural and subarachnoid blocks. Most of these complications are attributed to secondary intracranial hypotension due to cerebrospinal fluid leakage following dural puncture. Vocal fold paralysis (VFP) seems more likely to be overlooked and underreported due to delayed onset of symptoms and lack of attribution of dysphonia to spinal anesthesia. Therefore, VFP can often be missed and described as idiopathic. This article describes a case of VFP due to vagus nerve injury following subarachnoid block...

OBJECTIVES: Unilateral vocal fold paralysis (UVFP) typically results in marked changes in voice quality and performance and has a significant impact on quality of life. Treatment approaches generally aim to restore glottal closure for phonation and improve vocal function. There are a wide range of voice outcome measures that are available to measure the treatment effect. Careful selection of voice outcome measures is required to ensure that they are adequate for purpose and are psychometrically sound to detect the treatment effect...

PURPOSE: The uses of nimodipine for otolaryngic indications are reviewed, and recommendations for its use in clinical practice are provided. SUMMARY: Nimodipine is currently indicated for the improvement of neurologic outcomes in adult patients with aneurysmal subarachnoid hemorrhage (aSAH). However, other oral and i.v. calcium channel blockers have not exhibited the same beneficial effects in patients with aSAH, leading clinicians to believe that nimodipine possesses unique neuroprotective effects in addition to its calcium channel-blocking and vasodilatory properties...

INTRODUCTION: Unilateral vocal fold paralysis (UVFP) without an identifiable cause is termed idiopathic unilateral vocal fold paralysis (IUVFP). Some authors have postulated that select cases of IUVFP have a viral etiology, but the causality has not been established. We set out to review institutional cases of IUVFP and determine if there is a correlation between upper respiratory infection symptoms and presentation of IUVFP. METHODS: Cases of IUVFP were reviewed over a 10-year period (2002-2012)...

BACKGROUND: Continuous vagal intraoperative neuromonitoring (IONM) currently requires placement of a vagal nerve electrode. Herein, we present data from 100 patients (134 nerves-at-risk) monitored continuously during neck endocrine surgeries using a noninvasive, new methodology that solely utilizes endotracheal tube electrodes to simultaneously stimulate laryngeal mucosa and record a laryngeal adductor reflex continuous IONM (LAR-C-IONM) response. METHODS: The laryngeal adductor reflex (LAR) was elicited by electrical laryngeal mucosal stimulation on the side contralateral to the operative field using endotracheal tube electrodes...

OBJECTIVE: Aerodynamic measures of voice have historically been acquired using sustained phonation tasks. This study seeks to determine whether there are differences in airflow during sustained phonation (MFs), in running speech (MFrs), or during phonation in running speech (MFvrs). We also seek to determine whether these patterns are diagnostically significant. METHODS: Data were collected on 40 subjects (15 men, 25 women), ages 20-79, with a mean age of 53 in this prospective study...
