AI Article Synopsis

  • The text discusses the importance of the palatopharyngeus muscle in otolaryngology, emphasizing the need for more conservative surgical techniques based on its anatomy and neural supply.
  • It highlights that the muscle is primarily innervated by the pharyngeal plexus and lesser palatine nerves, which enter through its lateral border.
  • The conclusions suggest that the muscle is crucial for swallowing and speech, and calls for a reevaluation of pharyngoplasty procedures to align with a conservative and anatomically-focused approach for treating obstructive sleep apnea (OSA).

Article Abstract

Objectives: The author discusses current otolaryngological procedures employing the palatopharyngeus muscle, based on the surgical anatomy of the muscle and its neural supply. These techniques should be deeply revised for more conservative, anatomically-based maneuvers.

Methods: Revision of anatomical and surgical research and comments with the provision of a primary concept.

Results: The palatopharyngeus muscle is innervated by the pharyngeal plexus (the vagus and the accessory nerves) with additional fibers from the lesser palatine nerves. The innervation enters the muscle mainly through its lateral border.

Conclusions: The palatopharyngeus muscle has a fundamental role in swallowing and speech. The muscle helps other dilators to maintain upper airway patency. Sphincter pharyngoplasty should be revised as regards its role as a sphincter. Palatopharyngeal procedures for OSA employing the palatopharyngeus muscle should follow the conservative, anatomically-based, and non-neural ablation concept.

Objective: To compare the ototoxicity and survival in head and neck carcinoma patients treated with sequential (SEQ) and simultaneous integrated boost (SIB) of volumetric modulated arc therapy (VMAT).

Methods: This long-term prospective study enrolled patients with histologically confirmed head and neck carcinoma, all receiving VMAT treatment. Audiological assessments were done using various tests at baseline, two weeks, treatment completion, six months, and 12 months.

Tropomyosin is an actin-binding protein that plays roles ranging from regulating muscle contraction to controlling cytokinesis and cell migration. The simple nematode provides a useful model for studying the core functions of tropomyosin in an animal, having a relatively simple anatomy, and a single tropomyosin gene, , that produces seven isoforms. Three higher molecular weight isoforms (LEV-11A, D, O) regulate contraction of body wall and other muscles, but comparatively less is known of the functions of four lower molecular weight isoforms (LEV-11C, E, T, U).

Article Synopsis
  • Speech functions impacted by cleft palate involve complex sound production from various organs, and while traditional evaluations post-surgery are subjective, this study aims to provide objective assessments by measuring muscle contractions during speech.
  • A healthy volunteer underwent dynamic MRI while pronouncing Hindi syllables, allowing researchers to create 3D models of the palate and pharynx, then analyze muscle contractions using a finite element model for different sounds.
  • Results showed varying contraction levels for the palate and pharyngeal wall with different syllables, with the highest contractions for the syllable /k/ and the potential to use this data to quantify speech issues and evaluate surgical effectiveness in larger populations.

To establish a novel laryngopharyngeal reflux model in Bama minipigs excluding concurrent gastroesophageal reflux through endoscopic cricopharyngeal myotomy. Twelve 8-month-old male Bama minipigs were randomly assigned to three groups: Group 1 underwent cricopharyngeal myotomy alone, Group 2 underwent combined cricopharyngeal and lower esophageal sphincter myotomy, and Group 3 served as the control group. Following a one-week acclimatization period, the respective surgical procedures were performed.

Lonafarnib Protects Against Muscle Atrophy Induced by Dexamethasone.

J Cachexia Sarcopenia Muscle

February 2025

Department of Nanobiomedical Science & BK21 NBM Global Research Center for Regenerative Medicine, Dankook University, Cheonan, Korea.

Background: Muscle atrophy, including glucocorticoid-induced muscle wasting from treatments such as dexamethasone (DEX), results in significant reductions in muscle mass, strength and function. This study investigates the potential of lonafarnib, a farnesyltransferase inhibitor, to counteract DEX-induced muscle atrophy by targeting key signalling pathways.

Methods: We utilized in vitro models with C2C12 myotubes treated with DEX and in vivo models with Caenorhabditis elegans and DEX-treated Sprague-Dawley rats.
