“…Vocal folds can be described as two biomechanical layers: the body (thyroarytenoid muscle and DLP) and the cover (epithelium and SLP),[26,28,29] with a main difference between the cover and body layers arising from differences in their oscillation properties. The cover is characterized by its pliability and propagation of oscillatory waves in response to the contraction of the stiff body layer.…”

“…[30,31] The physiology of phonation that arises from the motion of the vocal folds was first explained by the myoelastic theory of voice production, a theory first developed by Johannes Muller and later modified by Van de Berg. [26] This theory describes the build-up of subglottic air pressure created by the lungs to drive the vocal folds apart. The minimum amount of lung pressure to initiate vocal fold abduction is known as the phonation threshold pressure (PTP).…”

“…[32,33] In simple terms, the Bernoulli effect causes a drop in pressure in the glottis which, in combination with their elastic properties, serves to drive the vocal folds back together. [26,34] More recently, Titze expanded this theory, demonstrating that the Bernoulli effect is only a minor contributor to the initiation of vocal fold oscillation. Rather, flow induced oscillation allows for sustained oscillation secondary to a continual transfer of energy from the glottal airstream to the tissue, overcoming frictional energy losses in the vocal folds.…”

“…Benninger and colleagues suggest that engaging in voice therapy may significantly improve a patient’s voice quality even after scar maturation. [5] Different therapy approaches may be recommended depending on the nature of the patient’s pathology as well as the patient’s concerns and motivation[26,36]. For example, a resonant voice approach (such as the Lessac-Madsen approach) targeting a specific laryngeal configuration may be useful to reduce both respiratory effort and impact of vocal fold vibration while achieving clearer voice quality.…”

Vocal folds are soft laryngeal connective tissues with distinct layered structures and complex multicomponent matrix compositions that endow phonatory and respiratory functions. This delicate tissue is easily damaged by various environmental factors and pathological conditions, altering vocal biomechanics and causing debilitating vocal disorders that detrimentally affect the daily lives of suffering individuals. Modern techniques and advanced knowledge of regenerative medicine have led to a deeper understanding of the microstructure, microphysiology, and micropathophysiology of vocal fold tissues. State-of-the-art materials ranging from extracecullar-matrix (ECM)-derived biomaterials to synthetic polymer scaffolds have been proposed for the prevention and treatment of voice disorders including vocal fold scarring and fibrosis. This review intends to provide a thorough overview of current achievements in the field of vocal fold tissue engineering, including the fabrication of injectable biomaterials to mimic in vitro cell microenvironments, novel designs of bioreactors that capture in vivo tissue biomechanics, and establishment of various animal models to characterize the in vivo biocompatibility of these materials. The combination of polymeric scaffolds, cell transplantation, biomechanical stimulation, and delivery of antifibrotic growth factors will lead to successful restoration of functional vocal folds and improved vocal recovery in animal models, facilitating the application of these materials and related methodologies in clinical practice.

Background In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR‐Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR‐Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence‐based findings and recommendation from the full document. Methods ICAR‐Allergic Rhinitis 2023 employed established evidence‐based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work. Results ICAR‐Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost. Conclusion The ICAR‐Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.
