Aim: This article attempts to describe the aging process of the vocal folds and the main features of the aged voice.
Background: In the world ageing population era, aging diseases and aging disorders are crucial. Voice disorders (presbyphonia) are common in the elderly and have a significant impact on communication and quality of life. Some of these disorders depend on the vocal folds, which consist of an extracellular matrix (ECM), fibrous proteins, interstitial proteins, and glycosaminoglycans. The density and spatial arrangement of these elements are important, as changes in their deposition can alter the biomechanical properties and vibratory function of the vocal folds.
Discussion: The aging voice process is analyzed in detail from mechanical factors like pulmonary bellows alteration, to hormonal factors and life style.
Conclusions: The elderly people undergoe mechanical, anatomical and functional changes: alterations of the pulmonary bellows, systemic changes like hormonal disregulation, and laryngeal changes, that resulting in hoarseness, which is difficult to treat.

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.
