Human vocal development is typically conceived as a sequence of two processes-an early maturation phase where vocal sounds change as a function of body growth ("constraints") followed by a period during which social experience can influence vocal sound production ("flexibility"). However, studies of other behaviors (e.g., locomotion) reveal that growth and experience are interactive throughout development. As it turns out, vocal development is not exceptional; it is also the on-going result of the interplay between an infant's growing biological system of production (the body and the nervous system) and experience with caregivers. Here, we review work on developing marmoset monkeys - a species that exhibits strikingly similar vocal developmental processes to those of prelinguistic human infants - that demonstrates how constraints and flexibility are parallel and interactive processes.

Purpose: The aim was to determine and compare the short-term effects of two intensive semi-occluded vocal tract (SOVT) programs, "straw phonation" (SP) and "resonant voice therapy" (RVT), on the phonation of children with vocal fold nodules.
Method: A pretest-posttest randomized controlled study design was used. Thirty children aged 6-12 years were randomly assigned to the SP group ( = 11), RVT group ( = 11), or control group receiving indirect treatment ( = 8) for their voice problems.

Introduction: There are inconsistencies in how different endoscopic procedures to manage Bilateral Vocal Fold Immobility (BVFI) have been described in the literature. This limits our ability to compare functional outcomes. There is no unifying international terminology available that precisely describes the anatomical boundaries and extent of the different types of treatment.

Background: Chondrosarcomas of the larynx, relatively rare tumors with low grade pathology in approximately 95% of cases, can most often be managed with conservation laryngeal procedures. Dedifferentiated chondrosarcomas are much more rare and aggressive requiring more aggressive surgical extirpation.
Methods: A patient underwent three debulking procedures for a laryngeal chondrosarcoma Grade I/II histologically over a 2.

Inflammation has been confirmed to play an important role in the occurrence and development of sudden sensorineural hearing loss(SSNHL), and the neutrophil-to-lymphocyte ratio(NLR) is a biomarker positively correlated with the degree of inflammation. This study aims to identify the difference in serum NLR between patients with SSNHL and normal population, and to evaluate the predictive efficacy of NLR for the occurrence and prognosis of SSNHL, thereby guiding the clinical diagnosis and treatment of SSNHL. In this study, 96 patients diagnosed with SSNHL admitted to our department from January 2023 to March 2024 and 96 patients diagnosed with vocal cord polyps admitted to our department during the same period were recruited as a control group.

Objective: Unilateral vocal fold paralysis (UVFP) frequently causes severe dysphonia, which necessitates multidisciplinary treatment. Literature on outcomes of interventions has primarily focused on vocal fold motility or instrumental vocal outcomes, but the perspectives of patients about the treatment process have not yet been investigated. The purpose of the study was therefore to explore patient experiences with healthcare for UVFP.
