The efficacies of CO2 laser and conventional laryngeal microsurgery for vocal cord benign (vocal cord polyp) and precancerous (vocal cord leukoplakia) lesions were compared. Patients with bilateral vocal cord polyps (n = 60) and leukoplakia (n = 30) were divided randomly into two groups. One group was treated with throat microsurgical instruments and underwent routine lesion resection (conventi...

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...

BACKGROUND Vocal cord sequelae and postoperative hoarseness during general anesthesia are a significant source of morbidity for patients and a source of liability for anesthesiologists. Several risk factors leading to laryngeal injury have been identified in the past. However, whether the quality of tracheal intubation affects their incidence or severity is still unclear. METHODS Eighty patie...

Phrenic nerve pacing can be used to treat congenital central Objective: hypoventilation syndrome (CCHS). We report how the lack of normal vocal cord tone during phrenic paced respiration can result in passive vocal cord collapse and produce obstructive symptoms. We describe a case of passive vocal cord collapse during phrenic Methods: nerve paced respiration in a patient with CCHS. As far as we...

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...

Introduction: Actinomycosis is a systemic chronic bacterial infection caused by Actinomyces Israelii, an anaerobic organism normally resident in the human mouth. However, the actinomycosis of the larynx is very rare, and only about 15 cases have been reported in the literature so far. Most of the cases reported occurred in patients who had previously undergone radiotherapy for laryngeal cancer...

Background Vocal cord nodules are bilateral swellings of the mid-portion of the membranous vocal folds. They are of variable size and are characterised histologically by thickening of the epithelium with a variable degree of inflammatory action in the underlying superficial lamina propria. They characteristically produce hoarseness. Treatment of vocal cord nodules aims to eliminate or reduce th...

Vocal cord dysfunction (VCD) is a term that refers to inappropriate adduction of the vocal cords during inhalation and sometimes exhalation. It is a functional disorder that serves as an important mimicker of asthma. Vocal cord dysfunction can be difficult to treat as the condition is often underappreciated and misdiagnosed in clinical practice. Recognition of vocal cord dysfunction in patients...

OBJECTIVES To evaluate whether the timing of early (≤6 months from time of nerve injury) vs. late (>6 months) injection medialization laryngoplasty impacts the need for subsequent open-neck reconstruction to restore vocal function in patients with unilateral vocal cord paralysis. STUDY DESIGN Retrospective chart review. METHODS A total of 112 outpatient or hospitalized adults with dysphonia...

INTRODUCTION Transcutaneous laryngeal ultrasonography (TLUSG) is a promising alternative to direct laryngoscopy in assessing perioperative vocal cord function. This study sought to evaluate the accuracy of TLUSG in assessing vocal cord function. METHODS Altogether, 204 patients underwent TLUSG and direct laryngoscopy before and after elective thyroidectomy. For both examinations, vocal cord m...
