Objectives: Laryngeal dystonia (LD) is characterized by irregular and involuntary task-specific spasms of the intrinsic laryngeal muscles. There is no curative treatment for it, however, laryngeal botulinum neurotoxin injections (BoNT-I) are considered the standard of care therapy. This study aims to characterize the population of LD patients and to assess the results of laryngeal BoNT-I.

Methods: A retrospective chart review was conducted of all new adult patients with benign vocal fold lesions with or without CRL, treated in the voice unit at Universidad Católica Clinical Hospital between 2015 and 2019. Patients were divided into two groups, without CRL (group A) and with CRL (group B).
Introduction: Bamboo nodes are transverse creamy-yellow subepithelial nodes in the vocal folds (VF) midpoint, usually bilateral, resembling a bamboo stem. They appear almost exclusively in females, and are associated with underlying autoimmune diseases.
Case Summary: Six female patients, 45.
Article Synopsis
- The study aimed to assess the prevalence and risk factors associated with voice disorders among healthcare workers in high-risk hospital settings during the COVID-19 pandemic.
- A questionnaire was distributed to 221 healthcare personnel, revealing that approximately 33% experienced voice issues in the past month, with 26.24% scoring abnormally on the Voice Handicap Index (VHI-10).
- Factors such as long working hours, extended mask use, and working in intensive care units were linked to higher VHI-10 scores, indicating an increased risk of voice disorders in these workers.
Introduction: Glottic insufficiency is an important cause of dysphonia and can be frequently overlooked in the clinical evaluation. The differential diagnoses of this entity are diverse and include postintubation phonatory insufficiency (PIPI). These patients present with glottic insufficiency symptoms, associated with normal laryngeal imaging evaluation with no evident lesions.

There is a broad differential diagnosis and the recommendation is to evaluate dysphonic children with an adequate laryngeal visualization method to achieve an accurate diagnosis and treatment.
Objective: To describe the experience in the diagnosis of dysphonia in children in the voice unit at Universidad Católica Clinical Hospital Santiago, Chile.
Introduction: Spasmodic dysphonia (SD) is a focal dystonia of the larynx where involuntary spasms of its intrinsic muscles are triggered by specific phonemes. The diagnosis is challenging and is performed by listening to the patient's voice, supported by nasolaryngoscopy. There is no diagnostic tool in Spanish for SD.
