29 cadaveric specimens of head and neck obtained from adults of both sexes following fixation in 5% formaldehyde were the material for the study. 43 samples of cervical ansa were examined. The investigation demonstrated that in the majority of cases (60.5%) cervical ansa was located exterior to internal jugular vein. The variants with the high position of cervical ansa in respect to the upper margin of thyroid cartilage were found in the samples with cervical ansa lying interiorly to the internal jugular vein.

Objectives The aim of this anatomical study was to analyze distances and anatomical relations between the lower cranial nerves and important neck landmarks. Methods Anatomical study based on neck dissection in Thiel-embalmed cadavers. Anatomical relations and distances between the vagus (X), accessory (XI), and hypoglossal (XII) nerves and important neck landmarks were registered and compared.

To explore the efficacy of ansa cervicalis anterior root-recurrent laryngeal nerve (RLN) anastomosis in the treatment of unilateral vocal fold paralysis (UVFP) and to analyze the effect of different pathogenic factors on efficacy. From January 2010 to January 2022, 428 patients (187 males and 241 females) at Changhai Hospital with UVFP who underwent ansa cervicalis anterior root-RLN anastomosis due to thyroid surgery, thoracic surgery, idiopathic vocal ford paralysis or high cranial base injury were analyzed. The course of nerve injury ranged from 6 to 24 months.

Article Synopsis
- Ansa cervicalis stimulation (ACS) is being explored as a therapy for obstructive sleep apnea (OSA) by stabilizing the pharynx and addressing collapse of various flow-limiting structures in the airway.
- A study involving 41 OSA participants measured the effects of ACS on airflow and identified the specific structures causing airflow limitations during sleep.
- Results indicated that ACS significantly reduced the collapsibility of all tested airway structures, with the most marked effects observed on the palatal and oropharyngeal walls, while factors like lower apnea-hypopnea index were linked to greater improvements in airway pressure.

Article Synopsis
- A systematic review and meta-analysis were conducted to evaluate the effectiveness of recurrent laryngeal nerve reinnervation in treating unilateral vocal cord paralysis (UVCP) by analyzing various studies.
- The analysis revealed significant improvements in vocal function metrics, including increased maximum phonation time and decreased scores in jitter, shimmer, and noise harmonic ratio post-surgery.
- Although different surgical methods showed similar outcomes, anastomosis of the ansa cervicalis nerve with the recurrent laryngeal nerve was noted as a preferable approach, indicating a need for more extensive randomized controlled trials for stronger evidence.
