Introduction: The authors present the layer structure of the vocal fold (by Hirano) indicating at the same time its clinical usefulness in laser chordectomy.
Materials And Methods: The authors describe the structure of the basement membrane sphere, i.e. the connection between the epithelium and the superficial layer of lamina propria, and the molecular structure of the extracellular matrix of mucosa.
Results: The biomechanical significance of fibre proteins and the extracellular matrix is emphasized with special attention paid to hialuronic acid and fibronectin.
Conclusions: Knowing the ultra-structure of the epithelium mucosa connection helps in understanding the mechanism of F0 production. The disorders in cooperation of the biomolecules of lamina propria of the vocal folds can influence the biomechanics of phonation.

The unprecedented technical and technological evolution in thyroid surgery has labelled it as an extremely safe and efficient procedure, and indeed "typifies perhaps better than any other operation the supreme triumph of the surgeon's art."-William Halsted, 1852-1922. Surgeon's experience reflected by annual case load is the most important denominator in thyroid surgery.

Purpose: The Daily Phonotrauma Index (DPI) can quantify pathophysiological mechanisms associated with daily voice use in individuals with phonotraumatic vocal hyperfunction (PVH). Since DPI was developed based on weeklong ambulatory voice monitoring, this study investigated if DPI can achieve comparable performance using (a) short laboratory speech tasks and (b) fewer than 7 days of ambulatory data.
Method: An ambulatory voice monitoring system recorded the vocal function/behavior of 134 females with PVH and vocally healthy matched controls in two different conditions.

The assessment of vocal function plays an important role in the diagnosis of voice disorders. With the continuous development of voice medicine in China, the evaluation, diagnosis, and treatment of voice disorders are gradually professionalized and standardized. Experts of the Subspecialty Group of Voice, Society of Otorhinolaryngology Head and Neck Surgery, Chinese Medical Association; Subspecialty Group of Laryngopharyngology, Editorial Board of Chinese Journal of Otorhinolaryngology Head and Neck Surgery reached the expert consensus through clinical research, literature search, and quality evaluation, as well as two meetings and two rounds of questionnaire voting.

Article Synopsis
- The study explored how human vocal fold fibroblasts (hVFF) interact with macrophages in the presence of cigarette smoke extract (CSE) and vibration, focusing on vocal fold inflammation.
- Researchers cultured hVFF with CSE, applying either static or dynamic conditions, and then measured various mRNA and protein levels to assess inflammation.
- Findings revealed that vibration may reduce CSE-induced inflammatory responses in hVFF, suggesting potential mechanisms to address voice disorders linked to smoking-related inflammation.

Background: Laryngeal respiratory dystonia (LRD) is diagnosed based on clinical presentation, patient history, and physical examination. Key indicators include dyspnea, desynchronized breathing patterns, and laryngoscopic findings that reveal vocal fold adduction during inspiration. Treatment for LRD remains controversial and often yields limited effectiveness.
