Effect of Temporary Vocal Fold Injection Medialization on the Rate of Permanent Medialization Laryngoplasty in Unilateral Vocal Fold Paralysis Patients

To determine whether temporary vocal fold injection affects the need for permanent medialization laryngoplasty in patients with unilateral vocal fold paralysis (UVFP).

Long-Term Effects of Injection Laryngoplasty With a Temporary Agent on Voice Quality and Vocal Fold Position

Patients with unilateral vocal fold paralysis (UVFP) treated with temporary injection laryngoplasty (IL) have a decreased rate of permanent medialization laryngoplasty (ML) compared to UVFP patients initially treated by observation. The aim of this study was to determine whether the lower rate of ML corresponded with improved quantifiable measures.

The Effect of office-based flexible endoscopic surgery on hemodynamic stability.

Because of technological advances in endoscopy equipment, office‐based flexible endoscopic surgery (OBFES) is becoming more widespread and common in practice. In our experience, we have noticed that patients often have marked rises in heart rate (HR) and blood pressure (BP). However, to our knowledge, changes in hemodynamic stability during these procedures have never been studied. The primary aim of this study was to investigate changes in BP, HR, and oxygen (O2) saturation in patients undergoing unsedated laryngeal surgery.

Botulinum toxin injections for new onset bilateral vocal fold motion impairment in adults

Review of clinical experience and results using botulinum toxin type A (BTX) for the management of adult patients with respiratory compromise due to new onset bilateral vocal fold motion impairment (BVFMI).

The physiologic impact of transnasal flexible endoscopy.

Diagnostic transnasal flexible endoscopy (TNFE) is a commonly used office procedure in otolaryngology. Currently there is a paucity of data on the impact of TNFE on physiologic parameters. This is relevant with the advent of office‐based endoscopic procedures. The goal of this study is to measure the impact of topical decongestion, anesthesia, and diagnostic TNFE on vital signs: systolic blood pressure (SBP) and diastolic blood pressure (DBP), heart rate (HR), and oxygenation (O2 sat).

Nomenclature proposal to describe vocal fold motion impairment

The terms used to describe vocal fold motion impairment are confusing and not standardized. This results in a failure to communicate accurately and to major limitations of interpreting research studies involving vocal fold impairment. We propose standard nomenclature for reporting vocal fold impairment. Overarching terms of vocal fold immobility and hypomobility are rigorously defined. This includes assessment techniques and inclusion and exclusion criteria for determining vocal fold immobility and hypomobility. In addition, criteria for use of the following terms have been outlined in detail: vocal fold paralysis, vocal fold paresis, vocal fold immobility/hypomobility associated with mechanical impairment of the crico-arytenoid joint and vocal fold immobility/hypomobility related to laryngeal malignant disease. This represents the first rigorously defined vocal fold motion impairment nomenclature system. This provides detailed definitions to the terms vocal fold paralysis and vocal fold paresis.

Stimulation threshold greatly affects the predictive value of intraoperative nerve monitoring.

Using a standardized, graded, intraoperative stimulation protocol, we aimed to delineate the effects of various stimulation levels applied to the recurrent laryngeal nerve on the postoperative predictive value of intraoperative nerve monitoring.

Injection laryngoplasty outcomes in irradiated and nonirradiated unilateral vocal fold paralysis

To evaluate the effect of radiation therapy on voice outcome and duration of effect of calcium hydroxylapatite (CaHA) injection laryngoplasty in unilateral vocal fold paralysis (UVFP) patients.

Static endoscopic evaluation of swallowing: Transoral endoscopy during clinical swallow evaluations

To determine the sensitivity and specificity for assessing pharyngeal residue, laryngeal penetration, and tracheal aspiration when comparing findings from the Static Endoscopic Evaluation of Swallowing (SEES) with findings from the Videofluoroscopic Swallow Study (VFSS).

Clinical and histologic predictors of voice and disease outcome in patients with early glottic cancer

To determine preliminarily if clinical or histological features of patients with laryngeal dysplasia/early carcinoma correlate with voice and disease outcomes.
