Objective: This guideline provides evidence‐based recommendations on managing hoarseness (dysphonia), defined as a disorder characterized by altered vocal quality, pitch, loudness, or effort that impairs communication reduces voice‐related quality of life (QOL). Hoarseness affects nearly one‐third the population at some point in their lives. applies to all age groups evaluated setting where would be identified managed. It is intended for clinicians who are likely diagnose and manage patients...
Objectives: High-speed digital imaging (HSDI), unlike stroboscopy, is a frequency-independent visualization technique that provides detailed biomechanical assessment of vocal physiology due to increased temporal resolution. The purpose this study was investigate the clinical value HSDI compared stroboscopy across 3 disorder groups classified as epithelial, subepithelial, and neurologic disorders. Methods: Judgments vibratory features fold edge, glottal closure, phase vertical level,...
Surgical treatment comparisons in rare diseases are difficult secondary to the geographic distribution of patients. Fortunately, emerging technologies offer promise reduce these barriers for research.To prospectively compare outcomes 3 most common surgical approaches idiopathic subglottic stenosis (iSGS), a airway disease.In this international, prospective, 3-year multicenter cohort study, 810 patients with untreated, newly diagnosed, or previously treated iSGS were enrolled after undergoing...
Treatment of glottal papillomatosis and dysplasia was mirror-guided performed in surgeons' offices the 19th century. It migrated to operating room 20th century accommodate direct laryngoscopic surgery, which required assistants administer anesthesia procedural support. Presently, primary treatment goals, are disease regression voice restoration or maintenance, tempered by morbidity general potential treatment-induced vocal deterioration. In fact, has been appropriately considered be an...
Current treatment options for idiopathic subglottic stenosis include endoscopic interventions, resection, and tracheotomy. Recently, serial office-based steroid injections were proposed as an alternative that may stabilize or induce regression of airway without the need repeated operations. Procedure completion rate, pain, complications, effect on stenosis, time since last operation, limitations have not been described.Retrospective case series.Retrospective series 19 patients undergoing...
Abstract Objectives/Hypothesis: The purpose of this study was to compare the clinical effectiveness type I thyroplasty, injection laryngoplasty, and graft implantation for treatment vocal fold scar pathologic sulcus vocalis. Study Design: Prospective, multi‐arm, quasi‐experimental research design. Methods: Twenty‐eight patients with newly diagnosed and/or vocalis were assigned one three modalities: thyroplasty (n = 9), laryngoplasty ( n 10). Psychosocial, auditory‐perceptual, acoustic,...
Abstract The North American Airway Collaborative (NoAAC) previously published a 3‐year multi‐institutional prospective cohort study showing variation in treatment effectiveness between 3 primary surgical techniques for idiopathic subglottic stenosis (iSGS). In this report, we update these findings to include 5 years of data evaluating effectiveness. Patients the NoAAC were re‐enrolled 2 additional and followed using prespecified protocol. Consistent with prior data, observation 487 iSGS...
Gore-Tex has been used as an effective implant for medialization laryngoplasty in the management of paralytic dysphonia; however, reporting large patient cohorts limited. Furthermore, use treatment glottal incompetence secondary to soft tissue defects not yet described. Finally, a number procedural nuances using have elucidated. A prospective investigation was done on 142 patients who underwent 152 laryngoplasties 183 vocal folds from December 1997 March 2002. The primary diagnoses prompting...
Objectives/Hypothesis Definitive tissue diagnosis for lesions warranting biopsy is shifting from the operating room to office. Safety, tolerance, factors related successful biopsy, and time treatment are not well‐defined. Methods Retrospective review of 116 patients undergoing in‐office oropharynx, larynx, or hypopharynx were included. Logistic regression determined if demographics, site, T‐stage, approach (transoral/transnasal) success. Time definitive was also analyzed. Results Ninety‐two...
Persistent dysphonia from vocal fold scar remains a clinical challenge, with current therapies providing inconsistent outcomes. We evaluated voice outcomes after single office-based steroid injection.Case series chart review.Academic medical center.This study was based on pre- and postoperative analysis of patient-reported, perceptual, acoustic, aerodynamic, videostroboscopic parameters. The sample comprised 25 patients undergoing dexamethasone injection into the superficial lamina propria...
Office-based steroid injection has shown promise for idiopathic subglottic stenosis (iSGS). It is important to understand safety and patient-lived experience. We report patient experience related airway restriction, voice, side effects.Sixteen patients (51 ± 14 years) with mild-moderate (20-50%) undergoing office-based transnasal injections were included; fourteen had prior operations. Patients typically underwent three injections, 1 month apart, followed by tracheoscopy later evaluate...
OBJECTIVE Our goal was to assess patient perception and acoustic characteristics of voice before after upper airway surgery. STUDY DESIGN AND SETTING We conducted a prospective assessment 44 surgical patients preoperatively postoperatively at tertiary care, academic hospital. Operations included septoplasty turbinectomy (n = 28) septoplasty, turbinectomy, uvulopalatopharyngoplasty, tonsillectomy 16). Patient opinion measures Voice Handicap Index score, vocal resonance, change in voice....
Every critical advancement in direct laryngoscopic surgical technique has enhanced its precision. Among the most notable was Killian's seminal description of suspension laryngoscopy 90 years ago, which allowed for bimanual surgery. Because technical difficulties encountered while performing laryngoscopy, Brünings and Seiffert designed fulcrum laryngoscope holder-stabilizers spatula laryngoscopes from original instrument design. Their devices, were easier to use better tolerated by patients,...
Adduction arytenopexy was designed as an innovation to arytenoid adduction, however the pragmatic issues regarding patient selection for these procedures has not been comprehensively assessed. A prospective examination performed on 100 consecutive patients who had undergone laryngoplastic phonosurgical reconstruction paralytic dysphonia. Seventy-seven of (77 per cent) were judged pre-operatively gain potentially significant phonatory enhancement from procedure. Fifty-six 77 (73 underwent...
Malignant transformation of laryngeal keratosis has been reported in a substantial subset patients, yet reliable criteria for predicting patients most at risk have to be determined. Current methods determining dysplasia ratings are susceptible errors biopsy sampling and interpretation. An understanding the genetic underpinnings progression vocal fold tumorigenesis may contribute creation predictive diagnostic criteria. We hypothesized that expression markers distinguish with keratotic...
A number of ultrasound techniques have been applied to identify the biomechanical properties vocal folds. These conventional methods, however, are not capable visually mapping concentration collagen and elastic fibers in folds form a parametric image. This study proposes use statistical parameter, Nakagami factor estimated from distribution ultrasonic signals backscattered tissues, as means for imaging folds.The were acquired four larynges (eight folds) obtained individuals without fold...
