OBJECTIVES/HYPOTHESIS: The objective of this study was to better define the relationship of laryngeal electromyography and video laryngostroboscopy in the diagnosis of vocal fold paralysis. STUDY DESIGN: Retrospective diagnostic cohort study with cross-sectional data analysis METHODS: Data were obtained from 57 patients with unilateral vocal fold paralysis who attended a large tertiary voice referral center. Electromyographic findings were classified according to recurrent laryngeal nerve, superior laryngeal nerve, and high vagal/combined lesions...

BACKGROUND: The purpose of this study was to determine the effect of fraction size on laryngoesophageal dysfunction among patients treated by chemoradiotherapy for laryngeal and hypopharyngeal cancer. METHODS: Forty patients underwent chemoradiotherapy for stage III/IV squamous cell carcinomas of the larynx and hypopharynx. Median radiation dose was 70 Gy (range, 69.3-70.4 Gy) with daily fractionation ranging from 2 Gy to 2.2 Gy. RESULTS: When comparing 2 Gy versus >2 Gy daily fractionation, there was no difference in 2-year overall survival (71% vs 72%; p = ...

REVIEW
Robert Brinton Fujiki, M Preeti Sivasankar
Vocal loading tasks (VLTs) are used to assess range of function and vulnerability of the laryngeal system. The manner in which VLTs compromise the laryngeal mechanism is multifaceted and only partially understood. This paper presents a scoping review of the literature on VLTs and their effects on the healthy voice. This review paper details the varied nature of VLT duration, task type, and additional factors including hydration and ambient noise that have been used to compromise the larynx. In addition, the voice measures used to assess the effects of VLTs on the healthy larynx are discussed...

For patients with large or recurrent laryngeal cancer, total laryngectomy surgery is usually performed. In the absence of a larynx, tracheoesophageal (TE) voice is the gold standard for alaryngeal phonation. The mechanisms underlying TE voice are unknown, but pharyngoesophageal (PE) segment vibration has been shown to play a key role. The aim of this study was to systematically explore the mechanics of PE segment vibration during TE phonation. A 2D axisymmetric finite-element model with two domains representing the air and PE wall was developed...

The objective of the preset study was to further improve the diagnostics and treatment of unilateral palsies of the laryngeal recurrent nerves associated with transitory reflective spasm of the functionally competent vocal fold. The study included 49 patients (46 women and 3 men) at the age varying from 21 to 75 years presenting with unilateral palsies of the laryngeal recurrent nerves associated with transitory reflective spasm of the functionally competent vocal fold that developed after the surgical intervention on the thyroid gland...

MATERIALS AND METHODS: This is an analysis of 29 patients with invasive, previously untreated T1and T2squamous cell carcinoma of true vocal cord that was treated by radical radiation therapy. DOSE AND FRACTIONATION: All patients were treated with a continuous course of radiation therapy with once-daily fractionation...

The goal of this study was to investigate the effects of a vocal loading challenge that combined prolonged speaking, in child-directed voice within a noisy environment, in older adults. An additional goal was to determine whether increased environmental humidity would attenuate the negative effects of this vocal loading challenge. METHOD: Thirteen healthy subjects (five males and eight females; >65 years) completed a vocal loading challenge. The challenge involved 45 minutes of child-directed speech in the presence of 65 dB multitalker babble background noise...

PURPOSE: This study aimed to compare musculoskeletal pain perception in teachers with voice disorders and in those with healthy voices, and to investigate the relationship between musculoskeletal pain and occupational variables (ie, work journey per week and working period). METHOD: Forty-three classroom teachers were divided into two groups: dysphonic group (DG), 32 classroom teachers with voice complaints and voice disorders; and non-DG, 11 classroom teachers without voice complaints and who are vocally healthy...

We know very little about how muscles and motor units in one region of the upper airway are impacted by adjustments in an adjacent airway region. In this case, the focus is on regulation of the expiratory airstream by the larynx and how changes in laryngeal aperture impact muscle motor unit activities downstream in the pharynx. We selected sound production as a framework for study as it requires (i) sustained expiratory airflow, (ii) laryngeal airway regulation for production of whisper and voice, and (iii) pharyngeal airway regulation for production of different vowel sounds...

Acoustic communication is fundamental to social interactions among animals, including humans. In fact, deficits in voice impair the quality of life for a large and diverse population of patients. Understanding the molecular genetic mechanisms of development and function in the vocal apparatus is thus an important challenge with relevance both to the basic biology of animal communication and to biomedicine. However, surprisingly little is known about the developmental biology of the mammalian larynx. Here, we used genetic fate mapping to chart the embryological origins of the tissues in the mouse larynx, and we describe the developmental etiology of laryngeal defects in mice with disruptions in cilia-mediated Hedgehog signaling...

OBJECTIVES: 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. METHODS: The study was conducted at a tertiary care center. Six patients presenting with hoarseness were admitted to a tertiary care otolaryngology office. These patients had asymmetrical thyroid cartilage prominence on palpation during physical examination...

BACKGROUND: Patients undergoing thyroidectomy often complain aerodigestive disorders. In a previous study we showed the associations between voice impairment and proximal acid reflux, swallowing impairment and Upper Esophageal Sphyncter (UES) incoordination and the decrease in UES pressure in thirty-six patients observed before and soon afterwards uncomplicated thyroidectomy. This study investigated the state of post-thyroidectomy esophageal motility changes and its associations with these disorders after 18-24 months...

This case report describes the use of trans-oral robotic surgery (TORS) for the excision of a combined laryngocele. Mixed or combined laryngoceles extend from the supraglottic larynx through the thyrohyoid membrane into the neck. Surgical excision for these benign lesions often requires combined external (transcervical) and internal (transoral endoscopic) approaches which carry significant morbidity. We present the case of a 37-year-old male who was diagnosed with a large laryngopyocele and was subsequently managed with a transoral excision using the da Vinci Si surgical robot system...

OBJECTIVES/HYPOTHESIS: This preliminary study investigated whether auditory-perceptual judgments of voice quality by experienced speech language pathologists were associated with instructions given to speakers to manipulate specific laryngeal postures. STUDY DESIGN: Experimental, within-subject design.

PURPOSE: To enable three-dimensional (3D) vocal tract imaging of dynamic singing or speech tasks at voxel sizes of 1.6 × 1.6 × 1.3 mm(3) at 1.3 s per image. MATERIALS AND METHODS: A Stack-of-Stars method was implemented and enhanced to allow for fast and efficient k-space sampling of the box-shaped vocal tract using a 3 Tesla MRI system. Images were reconstructed using an off-line image reconstruction using compressed sensing theory, leading to the abovementioned spatial and temporal resolutions...
