Potential Causative Factors for Saccular Disorders: Association with Smoking and Other Laryngeal Pathologies
To describe risk factors, clinical presentation, and outcome of patients with saccular disorders.Hemilaryngeal Microsomia: An Anatomic Variant
This study aims to describe a congenital laryngeal structural variant, hemilaryngeal microsomia (HLM), and to correlate identification on physical examination with computerized tomography scan (CT) and laryngoscopy findings.Human Papillomavirus Infection Status of Various Laryngeal Diseases in Japan: A Comprehensive Study
The aim of our study was to clarify the human papillomavirus (HPV) infection status of various laryngeal diseases in Tokyo, Japan.Laryngeal Trauma Following an Inhalation Injury: A Review and Case Report
The primary concern when managing a patient with inhalation injury is security of the airway. Airflow may be impeded by both edema of the upper airway and reduction of oxygen delivery to the lower respiratory tract. Although there has been much discussion regarding management of the latter, the focus of this article is the management of the former. This review aimed to determine the optimum management in burn victims with upper airway inhalation injury as an attempt to prevent laryngeal trauma leading to long-term voice disorders and upper airway dyspnea.Metabolic Mechanisms of Vocal Fatigue
This study aimed to identify potential metabolic mechanisms including (1) neuromuscular inefficiency, (2) cardiovascular recovery deficits, or (3) both, in individuals with complaints of vocal fatigue.Mid-membranous Vocal Fold Webs: Case Series
Laryngeal webs are a rare clinical entity, with those in the mid-membranous region occurring even less commonly. This is the first case series describing this condition.Laryngeal Schwannoma: A Case Presentation and Review of the Mayo Clinic Experience
The aim of this study was to clarify the nature of laryngeal schwannomas through review of the experience of a single institution during a 104-year period.Persistent Vocal Fold Granuloma Following Superficial PAAG Injection Laryngoplasty: A Case Report
The injection material polyacrylamide hydrogel (PAAG; Ferrosan, Søborg, Denmark) is often used as space filler for soft-tissue defects. PAAG is a suitable alternative to the materials used for injection laryngoplasty. Over the past decade, 427 patients have undergone injection laryngoplasty in our clinic using PAAG, and no major complications, such as material migration or foreign body granuloma, were identified. Here, we report the case of the first woman to undergo laryngomicrosurgery to remove a vocal fold granuloma that developed after a superficial injection laryngoplasty performed 4 years previously.Voice Disorders: Etiology and Diagnosis
Voice disorders affect adults and children and have different causes in different age groups. The aim of the study is to present the etiology and diagnosis dysphonia in a large population of patients with this voice disorder.for dysphonia of a large population of dysphonic patients.Office-based Autologous Fat Injection Laryngoplasty for Vocal Process Granuloma
To present the outcomes of office-based autologous fat injection laryngoplasty for the treatment of vocal process granuloma in conjunction with glottic insufficiency.Is Acupuncture Efficacious for Treating Phonotraumatic Vocal Pathologies? A Randomized Control Trial
To investigate the effectiveness of acupuncture in treating phonotraumatic vocal fold lesions.Treatment of Acute Vocal Fold Injury With Platelet-Rich Plasma
Platelet-rich plasma (PRP) is a reliable and has low side-effect profile and has beneficial effects on wound healing. Its investigatory effects on wound-healing process were shown on various tissues. The aim of the present study was to evaluate effectiveness of PRP application on scar tissue of acute vocal fold injury.Refractory Dysphonia Due to Isolated Cricothyroid Muscle Dystonia
To demonstrate the utility of electromyography (EMG) in the evaluation and management of treatment-resistant dysphonia.Leiomyosarcoma of Larynx as a Metachronous Tumor of Squamous Cell Carcinoma: An Unusual Case
Leiomyosarcomas (LMSs) are malignant tumors of smooth muscles accounting for 5–6% of all soft tissue sarcomas. They are mostly seen in the gastrointestinal tractus, the uterus, and the retroperitoneum. Soft tissue sarcomas comprise <1% of all laryngeal malignancies, most of which are chondrosarcomas. Laryngeal LMSs are rarely seen malignancies, which are published as case reports. We presented a case of laryngeal LMS, which was seen 4 years later in a laryngeal squamous cell carcinoma patient who underwent laryngeal laser microsurgery.In-Office Excision En Masse of a Vocal Process Granuloma Using the Potassium-Titanyl-Phosphate Laser
In-office laryngeal surgery is taking on a more commonplace role in the treatment of laryngeal disorders. The potassium-titanyl-phosphate (KTP) laser has been a resourceful adjunct to the management of patients with mucosal lesions of the vocal cords. However, a paucity of data exists for its use in postintubation granulomas treated in-office.Hyoid Bone Tenderness as a Clinical Indicator of Laryngeal Pathology
Hyoid bone tenderness is an underemphasized clinical abnormality and is described as discomfort or pain on gentle palpation of the greater cornu. The primary outcome of this study is to assess if there is any association between hyoid tenderness and laryngeal pathology.Surface-Evoked Laryngeal Sensory Action Potential Evaluation in Neurogenic Chronic Cough
Neurogenic chronic cough is currently a diagnosis of exclusion. We hypothesized that surface-evoked laryngeal sensory action potential (SELSAP) testing could be used to help establish a diagnosis of laryngeal sensory neuropathy as a cause of chronic cough, based on altered SELSAP waveform morphology.Subglottic Extramedullary Plasmacytoma With Light Chain Multiple Myeloma Masquerading as Adult-Onset Asthma
Extramedullary plasmacytoma (EMP) arises outside the bone marrow and can be associated with multiple myeloma (MM). A 55-year-old gentleman, who presented with dyspnea and expiratory wheeze, was diagnosed and treated for asthma. A subsequent relapse 6 months later prompted an Otolaryngology consult. Preliminary findings showed a benign-looking nodular lesion at the subglottis. Work-up at our institution revealed an Fludeoxyglucose (FDG) avid left subglottic lesion with multiple bone metastases on a Positron Emission Tomography / Computed Tomography (PET/CT).Functional Endoscopic Analysis of Beatbox Performers
Beatboxing is a form of vocal percussion in which performers imitate drum sounds, interspersed with vocalization and other sounds, using their vocal tracts. Although similarities between beatboxing and singing are expected because of the anatomy involved, the medical literature has a wealth of information on singing and minimal studies on beatboxing. The objective of our study was to report on a case series of functional endoscopic evaluation of the anatomy involved in beatboxing and determine whether beatboxing may be a risk factor for phonotrauma or if this form of vocalization might be protective of the vocal folds.Inflammatory Myofibroblastic Tumor of the Larynx—A Case Report
Inflammatory myofibroblastic tumor (IMT) is a borderline neoplasm with uncertain malignant potential. It is a rare disease also referred to as an inflammatory pseudotumor, a plasma cell granuloma, and an inflammatory fibrosarcoma. IMT rarely also involves the head and neck region with only 50 cases of laryngeal IMT reported in the literature, and this is the first case with reported magnetic resonance imaging (MRI) findings.Dysphonia in Performers: Toward a Clinical Definition of Laryngology of the Performing Voice
To identify causes of dysphonia in performers and compare causes and aspects of treatment of dysphonia in performers and nonperformers.Lesions of the Posterior Glottis: Clinical and Pathologic Considerations and Treatment Outcome
To assess the clinical profile, presentation, prognosis, and response to treatment of patients with posterior glottic lesions and the prevalence of malignancy in this group.Spindle Cell Carcinoma of the Larynx Presenting as a Vocal Fold Cyst
Spindle cell carcinoma (SPCC) is a rare, malignant variant of squamous cell carcinoma (SCC), which shows biphasic proliferation of the conventional SCC component and malignant spindle shape cells with sarcomatous appearance. We present two cases of SPCC of the true vocal fold that presented as a benign appearing subepithelial mass. We discuss the patient presentation, voice assessment, surgical treatment, and a review of the literature.Pediatric Arytenoid Dislocation: Diagnosis and Treatment
Arytenoid dislocation and subluxation are well-described injuries in adults but are poorly documented in children. The most commonly cited etiology is intubation trauma although external blunt trauma also is recognized. Symptoms include dysphonia, vocal fatigue, loss of vocal control, breathiness, odynophagia, dysphagia, dyspnea, and cough. Prompt diagnosis and treatment lead to the best chance for recovery, and delayed treatment is likely to result in scarring and possibly ankylosis. The mean age of our study group was 12.3 years and consisted of six males (55%) and five females (45%).Laryngeal Chondrosarcoma of the Arytenoid Cartilage Presenting as Bilateral Vocal Fold Immobility: A Case Report and Literature Review
To describe an atypical case of laryngeal chondrosarcoma of arytenoid cartilage presenting as bilateral vocal fold immobility and to avoid potential missed diagnosis.
