Ultrasound measurements of the vocal folds were taken for a number of boys passing through puberty. The boys were grouped according to their pubertal stage as defined by Tanner and there was a gradual increase in the length of the vocal folds as puberty progressed. The fundamental frequency of the boys' speaking voice was recorded via laryngography and a good correlation between the length of the vocal folds and the frequency of the voice was seen. The sudden drop in frequency seen between Tanner stages 3 and 4 did not correlate with similar changes in the length of the vocal folds at this time but stroboscopic findings suggest a change in the structure and mass of the vocal folds at this time of maximum frequency change.

In otolaryngology, training often involves simulation in animal specimens, human cadavers, and artificial models to facilitate learning surgical procedures, reducing the time needed to acquire essential skills. Simulated training has become integral to medical education, particularly in microsurgical techniques, such as microlaryngeal surgery. These procedures, also known as phonomicrosurgery, are performed on the vocal folds using microscopic visualization and precision instruments with long shafts and millimetric tips.

This report describes a rare case of a paraganglioma occurring beneath the vocal folds. During the preoperative biopsy, we encountered significant hemorrhage, forcing us to stop the procedure and preventing us from obtaining a definitive diagnosis. Despite these challenges, the eventual surgery had a good outcome.

Background: The Neonatal Resuscitation Program recommends direct laryngoscopy (DL) as the primary method for neonatal intubation. Video laryngoscopy (VL) is suggested as an option, particularly for training novice operators or for intubating infants with difficult airways. The programme outlines specific steps for intubation, including managing the external environment and techniques for visualising key anatomical landmarks.

When a difficult airway is anticipated, awake tracheal intubation can be considered. Usually, low doses of sedatives are administered during this procedure for minimal sedation and anxiolysis, such as midazolam and remifentanil. The newly developed ultra-short-acting benzodiazepine remimazolam has a pharmacokinetic profile that is more suitable for titration during awake tracheal intubation than the long-acting midazolam.

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.
