  • does the investing layer of the deep Cervical Fascia exist
    Anesthesiology, 2005
    Co-Authors: Lance Nash, H D Nicholson, Ming Zhang
    Abstract:

    Background:The placement of the superficial Cervical plexus block has been the subject of controversy. Although the investing Cervical Fascia has been considered as an impenetrable barrier, clinically, the placement of the block deep or superficial to the Fascia provides the same effective anesthesi

  • The investing layer of the deep Cervical Fascia does not exist between the sternocleidomastoid and trapezius muscles.
    Otolaryngology-Head and Neck Surgery, 2002
    Co-Authors: Ming Zhang
    Abstract:

    OBJECTIVE: We sought to describe the 3-dimensional organization of connective tissues in the suboccipital region. STUDY DESIGN AND SETTING: We conducted a sectional anatomic investigation with the use of E12 sheet plastination. SUBJECTS: Six human adult cadavers (2 male and 4 female; age range, 54 to 86 years) were used in this study. Five of them were sectioned as 2.5-mm-thick coronal (1 cadaver), transverse (2 cadavers), or sagittal (2 cadavers) sections. RESULTS: No aggregation of fibrous connective tissue was seen between the sternocleidomastoid and trapezius muscles. The intervening space was fully occupied by fatty tissue that was indistinguishable from the subcutaneous tissue. CONCLUSIONS: The investing layer of the deep Cervical Fascia is incomplete so that the carotid sheath is directly exposed to the subcutaneous tissue via a gap between the sternocleidomastoid and trapezius muscle. SIGNIFICANCE: This anatomic feature should be considered when designing a minimally invasive endoscopic approach to the carotid sheath and the surrounding deep Cervical structures.

  • anatomic relationship between right recurrent laryngeal nerve and Cervical Fascia and its application significance in anterior Cervical spine surgical approach
    Spine, 2017
    Co-Authors: Jianlin Shan, Heng Jiang, Chongwei Wang
    Abstract:

    STUDY DESIGN: An anatomic study of anterior Cervical dissection of 42 embalmed cadavers. OBJECTIVE: The aim was to study the anatomic relationship between recurrent laryngeal nerve (RLN) and Cervical Fascia combined with the requirements in anterior Cervical spine surgery (ACSS). SUMMARY OF BACKGROUND DATA: There has been no systematic research about how to avoid RLN injury in anterior Cervical spine surgical approach from the aspect of the anatomic relationship between RLN and Cervical Fascia. METHODS: Forty-two adult cadavers were dissected to observe the relationships between RLN and different Cervical Fascia layers. RESULTS: RLN pierced out the alar Fascia from the inner edge of the carotid sheath in all cases, and the piercing position in 22 cases (52.4%) was located at the lower segment of T1. The enter point into visceral Fascia of RLN was located at C7-T1 in 25 cases (59.5%). The middle layer of deep Cervical Fascia exhibited the most stable anatomic relationship with RLN at the carotid sheath confluence site. Pulling visceral sheath leftwards would significantly increase the RLN tension. CONCLUSION: Using the close and stable relationship between RLN and Cervical Fascia could help to avoid RLN injury in anterior Cervical spine surgical approach. LEVEL OF EVIDENCE: 4.

  • unusual third head of the sternocleidomastoid muscle from the investing layer of Cervical Fascia
    International Journal of Morphology, 2012
    Co-Authors: Srinivasa Rao Sirasanagandla, Kumar M R Bhat, Narendra Pamidi, Nagabhooshana S Somayaji
    Abstract:

    El origen anormal, presencia de una cabeza adicional y disposicion en capas de fibras son las variaciones reportadas del musculo esternocleidomastoideo. En el presente estudio, se presenta un origen poco habitual de la tercera cabeza del musculo esternocleidomastoideo en un cadaver de sexo masculino de 60 anos. La cabeza supernumeraria se originaba en la lamina superficial de la Fascia Cervical en el techo del triangulo subclavio proximo de la clavicula y cruzaba oblicuamente hacia arriba y adelante para fusionarse con la cabeza clavicular. La insercion e inervacion del musculo eran normales.

    Abstract:

    SUMMARY: The abnormal origin, presence of additional head and layered arrangement of fibers are the reported variations ofsternocleidomastoid muscle in the past. In the present case we report a rare unusual origin of third head of the sternocleidomastoidmuscle in a 60 year-old male cadaver. This additional head originated from the investing layer of Cervical Fascia in the roof of thesubclavian triangle close to the clavicle and traversed obliquely upward, forward and fused with clavicular head. The insertion and nervesupply of the muscle was found to be normal.˚ KEY WORDS: Sternocleidomastoid muscle; Anatomical variation; Third head. INTRODUCTIONSternocleidomastoid muscle lies obliquely across theside of the neck and divides the side of the neck into anteriorand posterior triangles. It originates as two heads, the medialor the sternal head which is tendinous and rounded; and thelateral or the clavicular head. The sternal head originates fromthe upper part of the anterior surface of the manubrium sterni.The lateral head originates from the superior surface of themedial end of the clavicle. The triangular interval betweenthe two heads of origin forms a surface depression, the lessersupraclavicular fossa. The two heads blend into round, thickmuscle belly which is then inserted as a strong tendon ontothe lateral surface of the mastoid process from its apex tosuperior border, and as a thin aponeurosis into the lateral halfof the superior nuchal line of the occipital bone.The muscle is innervated by the spinal part ofaccessory nerve along with branches from ventral rami ofC2-3 and sometimes ventral rami of C4 spinal nerves. It isvascularized by the branches of suprascapular, superiorthyroid, occipital and posterior auricular arteries. Actingalone, the sternocleidomastoid muscle flexes the necklaterally and rotates the face to the opposite side. Actingtogether, the muscle of two sides flexes the head and neckforcibly (Williams et al., 1995).
