AI Article Synopsis
- A selective blocking method for the cervical plexus and sympathetic trunk hasn't been established yet, prompting research into neck anatomy.
- Researchers examined 28 cadavers and conducted CT scans on 2 healthy volunteers to study local anesthetic distribution.
- Findings revealed the deep cervical plexus's location between specific neck muscles and identified the longus capitis as a suitable landmark for blocking these nerves during procedures.
Article Abstract
Background: A selective blocking method for the cervical plexus and the cervical sympathetic trunk has not yet been established.
Methods: We performed a detailed examination of the neck anatomy using 28 cadavers. The pattern of local anesthetic distribution after injection in 2 healthy volunteers was imaged using computed tomographic scan.
Results: The deep cervical plexus was located in the groove between the longus capitis and scalenus medius muscles. The cervical sympathetic trunk was located on the anteromedial surface of the longus capitis. Although anesthetic injected into the longus capitis was confined to the muscle, it infiltrated into neighboring structures including the C2 to C5 roots and sympathetic trunk.
Conclusions: The longus capitis muscle is a suitable landmark for blocking the cervical plexus and trunk.

: Charcot-Marie-Tooth (CMT) disease is an inherited peripheral neuropathy primarily involving motor and sensory neurons. Mutations in INF2, an actin assembly factor, cause two diseases: peripheral neuropathy CMT-DIE (MIM614455) and/or focal segmental glomerulosclerosis (FSGS). These two phenotypes arise from the progressive degeneration affecting podocytes and Schwann cells.

Objectives: Complete removal of the tumor and surrounding tissue is the most important prognostic factor such as survival after surgery. When the tumor invades the phrenic nerve, the impact of intraoperative phrenic nerve sacrifice on the short- and long-term prognosis of patients is not clear. This study aims to explore the differences in prognosis between patients with malignant thymoma with and without phrenic nerve sacrifice during surgery, as well as analyze related factors.

Background: It is very well known that the supraclavicular nerve (SCN) which occupies the inferior part of the superficial cervical plexus basically originates from the ventral rami of C2-C4, then travels caudally into the investing layer of the deep cervical fascia (IL-DCF) alternatively termed the "prevertebral fascia."
Methods: This cadaveric study (a total of 6 soft-embalmed cadavers and bilateral dissections, i.e.

Mediastinal mass syndrome represents a major threat to respiratory and cardiovascular integrity, with difficult evidence-based risk stratification for interdisciplinary management. We conducted a narrative review concerning risk stratification and difficult airway management of patients presenting with a large mediastinal mass. This is supplemented by a case report illustrating our individual approach for a patient presenting with a subtotal tracheal stenosis due to a large cyst of the thyroid gland.

Eversion carotid endarterectomy (CEA) in awake patients is performed using cervical plexus blocks (CPBs) with or without carotid artery sheath infiltration (CASI) under ultrasound guidance. Although adequacy of anesthesia (AoA) guidance monitors nociception/antinociception balance, its impact on intraoperative analgesia quality and perioperative outcomes in awake CEA remains unexplored. Existing literature lacks evidence on whether AoA-guided anesthesia enhances clinical outcomes over standard techniques.
