AI Article Synopsis
- The study analyzed cervical region measurements from CT scans of 60 healthy individuals between 20 and 83 years old, establishing normal values and variations.
- The research focused on the sagittal diameter of prevertebral soft tissue, upper respiratory tract lumina, and the dimensions of the thyroid gland and major cervical vessels.
- It also measured distances between the cervical spine and key laryngeal and hypopharyngeal points, along with vocal cord movement during breathing and speaking to assess laryngeal function.
Article Abstract
Radiodiagnostically relevant normal values and variations for measurements of the cervical region, the arithmetical average and the standard deviation were determined from adequate computer tomograms on 60 healthy women and men, aged 20 to 83 years. The sagittal diameter of the prevertebral soft tissue and the lumina of the upper respiratory tract were evaluated at exactly defined levels between the hyoid bone and the incisura jugularis stuni. The thickness of the aryepiglottic folds, the maximal sagittal and transverse diameters of the thyroid gland and the calibre of the great cervical vessels were defined. To assess information about laryngeal function in computerized tomography, measurements of distances between the cervical spine and anatomical fixed points of the larynx and hypopharynx were made as well as of the degree of vocal cord movement during normal respiration and phonation.

Transportation Insecurity, Social Support, and Adherence to Cancer Screening.
JAMA Netw Open
January 2025
S-SPIRE Center, Department of Surgery, Stanford University School of Medicine, Stanford, California.
Importance: Transportation insecurity and lack of social support are 2 understudied social determinants of health that contribute to excess morbidity, mortality, and acute health care utilization. However, whether and how these social determinants of health are associated with cancer screening has not been determined and has implications for preventive care.
Objective: To determine whether transportation insecurity or social support are associated with screening adherence for colorectal, breast, and cervical cancer.

Importance: Retrograde cricopharyngeus dysfunction (R-CPD) is an emerging disorder associated with disabling symptoms. The origin of R-CPD remains unknown.
Objective: To investigate the development of symptoms, diagnosis approach, and therapeutic outcomes of R-CPD in patients treated with in-office botulinum toxin injection (BTI) into the cricopharyngeus.
Selective Neurectomy with Regenerative Peripheral Nerve Interface Surgery for Facial Synkinesis.

Division of Facial Plastic and Reconstructive Surgery, Department of Otolaryngology-Head & Neck Surgery, University of Michigan, Ann Arbor, Michigan, USA.
Selective neurectomy (SN) typically leaves cut nerve endings to be either free-floating or buried in facial muscles. Regenerative peripheral nerve interfaces (RPNIs) use autologous skeletal muscle grafts to provide a nonfacial muscle target for reinnervation. To evaluate the effectiveness of RPNI surgery with SN for improving postoperative facial function through botulinum toxin use and facial movement metrics.
