OBJECTIVES: Postoperative evaluations of patients, who undergo of transoral thyroarytenoid myoneurectomy using CO2 laser for the treatment of Adductor Spasmodic Dysphonia (ASD), reveal some residual laryngeal symptoms such as intermittent spasms, vocal effort, and stiffness in laryngeal muscles which can be identified on videolaryngo-stroboscopy (VLS) by patterns of Muscle Tension Dysphonia (MTD) and mucosal wave, and as deviations in acoustic perceptual measures. This study aims to document these vocal symptoms observed postoperatively, and most importantly highlight the need for voice therapy postoperatively and report the short-term vocal outcomes post-therapy...

OBJECTIVE: Numerous methods and materials are available for vertical partial laryngectomy. In this study, the reparative effects of the platysma myocutaneous flap (PMF) and ribbon myocutaneous flap (RMF) on the postoperative voice quality of patients were compared to provide a reference for selecting a method conducive to improving postoperative voice quality. METHODS: A retrospective analysis was performed on patients with unilateral T2-3 glottic carcinoma. Following vertical partial laryngectomy, the defect was repaired with a PMF or simple RMF...

OBJECTIVE: Mature vocal fold nodules and fibrous phono-traumatic lesions that have failed standard voice therapy can be challenging. Autologous platelet-rich plasma (PRP) is rich in growth factors and easily obtained from a simple blood draw. Growth factor injection into the vocal folds may reverse the scar and inflammation in recalcitrant, bilateral phono-traumatic lesions such as mature vocal fold nodules. This study reports the short-term (3months) voice results after PRP injection in 11 subjects with recalcitrant, bilateral phono-traumatic lesions that have failed voice therapy...

INTRODUCTION: Chronic refractory cough is defined as cough lasting greater than 8 weeks and with an unclear etiology. Blockade of the internal branch superior laryngeal nerve (iSLN) has been shown to be safe and effective in the treatment of chronic cough. It remains unknown, however, if underlying comorbidities impact patient response to iSLN blockade. METHODS: A total of 44 patients aged 18 years and older were seen at our institution's Laryngology clinics between 2019 and 2022 and treated with iSLN blockade...

OBJECTIVE: The videolaryngostroboscopy parameters form (VLSP form) is a diagnostic tool for the collection of videolaryngostroboscopic basic findings through the evaluation of 12 parameters. The aim of the present study is to preliminarily investigate intra- and inter-rater reliability, validity and responsiveness of the VLSP form. METHODS: A study on a total amount of 160 forms for the evaluation of VLS basic findings was carried out. 80 forms were scored through the VLSP form and 80 with the Voice Vibratory Assessment with Laryngeal Imaging (VALI) form Stroboscopy (S) by four expert phoniatricians, that blindly scored the VLS recordings of 5 subjects without voice disorders and 5 patients with organic voice disorder before and after successful phonosurgery...

OBJECTIVES: This study evaluated the validity of two videolaryngostroboscopic (VLS) rating tools to detect differences in VLS ratings between normophonic speakers, mild, and moderate-severely dysphonic speakers. METHODS: Sixteen rigid VLS exams were obtained from four normophonic controls and 12 speakers with dysphonia (8 =mild, 4 =moderate-severe) secondary to laryngeal pathology. Eight clinicians rated nine vibratory VLS parameters for each exam using both the Voice-vibratory Assessment of Laryngeal Imaging (VALI) tool and a 100 mm visual analog scales (VAS)...

INTRODUCTION: Quantitative measurement and analysis of glottic abduction is used to assess laryngeal function and success of interventions; however, the consistency of measurement over time has not been established. This study assesses the consistency of glottic abduction measurements across visits in healthy patients and anatomic factors impacting these measurements. METHODS: Review of patients with two sequential flexible stroboscopic exams over seven months from 2019-2022...

OBJECTIVE: Gender-affirming laryngeal surgery (GALS) procedures are effective, with high rates of patient satisfaction following endoscopic vocal fold shortening (glottoplasty) or chondrolaryngoplasty. Despite this, complications and functional limitations in voice use following GALS are not well described. The current study aims to visually characterize the clinical and laryngoscopic features of complications following GALS. METHODS: Patients who presented with complications or subjective dysphonia following glottoplasty or chondrolaryngoplasty across three tertiary care centers were included...

OBJECTIVE: Platelet-rich plasma (PRP) is rich in growth factors and is easily obtained from blood samples. Long-term data after PRP injection into the larynx should be improved. This study reports the short-term (3 months) and long-term (12 months) voice results after PRP injection. MATERIALS AND METHODS: Sixty-three patients with scars ( n  = 34), sulcus vocalis ( n  = 17), recalcitrant nodules ( n  = 5), atrophy ( n  = 4), or a combination of these ( n  = 3) were included (158 injections; median follow-up = 12...

Background: Arytenoid cartilage dislocation is considered as a rare laryngeal injury and closed reduction is commonly used as the first choice for the arytenoid dislocation. However, the tools of closed reduction vary, and there is no dedicated tool for closed reduction, and the treatment outcome varies from person to person. This study compared the treatment outcome of the modified laryngeal forceps and traditional laryngeal forceps. Material and Methods: This study conformed to the strengthening the reporting of observational studies in epidemiology guidelines regarding retrospective studies...

Submucosal laryngeal lesions have proven themselves to be a diagnostic challenge in the field of medicine, often presenting inconsistently between endoscopic visualization, various imaging modalities, and biopsy. The conflicting clinical picture can lead to a delay in definitive diagnosis and treatment. A variety of laryngeal imaging modalities exist that give a unique perspective of the tumor being evaluated and can be used in combination to clarify discrepancies in presentation.  This report describes the clinical course of an undiagnosed laryngeal squamous cell carcinoma (SCC) presenting with persistent dysphonia, dysphagia, and unilateral vocal fold immobility...

Granular cell tumors (GCTs) are rare benign tumors that can occur in any part of the body. They are most commonly found in the head and neck region, especially the tongue. Laryngeal GCTs are rare, accounting for only 3% to 10% of all GCTs. This case report describes a 4-year-old boy with a laryngeal GCT. The patient presented with a history of hoarseness for 2 years. Stroboscopy revealed a large mass occupying the entire length of the left vocal cord. The mass was successfully removed by microlaryngeal surgery with laser ablation...

OBJECTIVES/HYPOTHESIS: Cysts are benign vocal fold lesions typically divided into mucous retention or epidermoid subtypes. The conventional paradigm that the former are translucent and the latter opaque fails to encompass the heterogeneity of cyst appearance on laryngoscopy. This study aims to characterize the relationships between clinical cyst characteristics and histopathology. STUDY DESIGN: Retrospective cohort METHODS: Clinicodemographic data, videostroboscopy findings, and histopathology results were retrospectively reviewed for adults who underwent surgical excision of vocal fold cysts at our institution between 2006 and 2021...

The use of operating microscope and rigid telescope in laryngeal surgery represents one of the most exciting advances. Both systems provide good illumination, magnification and relative ease of operation. Microlaryngeal surgery (MLS) with suspension laryngoscope is currently considered the gold standard for surgical approach to the larynx for excision of benign lesions of vocal folds. The limitation of this technique is intubation, general anesthesia (GA) related and in difficult exposure of larynx. The development of ideal anesthetic system has not been successful in satisfying both the surgeon and the anesthesiologist...
