during the past few years, researchers and practitioners have developed novel techniques, using ansa cervicalis to innervate muscles of the larynx paralyzed due to surgical procedures carried out in the chest and neck areas. during routine dissection of a middle-age male cadaver, an unusual course of the superior root of the ansa cervicalis was observed. in this case, the superior root of the a...

We studied the variations in the ventral rami of 152 brachial plexuses in 77 Korean adults. Brachial plexus were composed mostly of the fifth, sixth, seventh and eighth cervical nerves and the first thoracic nerve (77.0%). In 21.7% of the cases examined, the fourth, fifth, sixth, seventh and eighth cervical and the first thoracic nerves contributed to the plexus. A plexus composed of the fourth...

Regional anesthetic block of the cervical plexus is a safe and useful alternative to general endotracheal anesthesia for surgery of the neck, upper shoulder, and occipital scalp area. The sensory component of the cervical plexus can be blocked separately and easily by a superficial cervical plexus block. Both motor and sensory block can be obtained by deep cervical plexus block. Minor transient...

PURPOSE Secondary hyperparathyroidism (SHPT) develops in patients with chronic renal failure. This study aimed to compare analgesic efficacy in SHPT patients who undergo subtotal parathyroidectomy after superficial versus deep cervical plexus block. METHODS Sixty chronic renal failure patients with SPHT scheduled for subtotal parathyroidectomy were randomized to receive general anesthesia (gr...

The Effects of Ultrasound-guided and Anatomic landmark-based Superficial Cervical Plexus Block on Post-operative Pain Intensity in Thyroidectomy Patients: A Clinical Trial

Background and Purpose: Regional anesthesia is the choice for patients undergoing preventive open carotid surgery. Recently intermediate cervical plexus block has been described as a reliable and safe anesthesia technique in comparison with superficial and deep cervical plexus block. The aim of our study was to assess the complications of intermediate cervical plexus block in high risk patients...

BACKGROUND A thorough understanding of the topographical anatomy of the spinal accessory nerve and the cervical plexus branches is a basic prerequisite for positive results when operating on the neck. OBJECTIVE To give an exact description of the topographical and surgical anatomy of the spinal accessory nerve (SAN) and the trapezius branches of the cervical plexus. DESIGN Anatomic analysis...

Anatomy of the brachial plexus Roots The brachial plexus is most commonly formed by five roots originating from the ventral divisions of spinal nerves C5 through T1. The roots of the plexus are located in the cervical paravertebral space, between the anterior and middle scalene muscles. Besides understanding its origins, it is also important to understand the plexus in terms of the relative sur...

Adult brachial plexus injuries frequently lead to significant and permanent physical disabilities. Investigating the mechanism of the injury using biomechanical approaches may lead to further knowledge with regard to preventing brachial plexus injuries. However, there are no reports of biomechanical studies of brachial plexus injuries till date. Therefore, the present study used a complex three...
