まとめ

前頸椎外科手術でしばしば遭遇するオモヒオイド筋は,阻害性であるときに安全に切断することができます. このアプローチは,重要な副作用なしに,外科視覚化と効率を向上させる可能性があります.

科学分野:

アナトミーアナトミー
脊椎外科手術について
外科手術のテクニック

背景:

オモヒオイド筋は,特にC5-C7レベルで,前頸椎手術中に頻繁に遭遇します.
その上部の腹部が手術の通路を妨げるため,外科医は保存,収縮,または切断のどちらかを選択する必要があります.
脊髄に関する文献では,この筋肉に限られた重点が置かれています.

研究の目的:

オモヒオイド筋の変動性,外科的処置,および前頸椎解剖と融合 (ACDF) の術後の結果に関する解剖学的および臨床的証拠を合成する.
上部オモヒオイド腹部の切断が,外科的曝露と患者のアウトカムに与える影響を評価する.

主な方法:

この研究は,解剖学的および臨床的証拠を合成したナラティブレビューです.
ACDFにおけるオモヒオイド筋に関連する解剖学的変異,外科的操作技術,および術後のアウトカムを調べています.

主要な成果:

解剖学的研究では,オモヒオイド筋の有意な変動が示され,アクセサリースリップや異常な挿入が含まれています.
新興の臨床データによると,上腹部を切断すると可視化が改善され,手術期間と失血が減少する可能性がある.
切断は,ディスファギア,ディスフォニア,または美容上の懸念を有意に増加させるようには見えません.

結論:

オモホイオイド筋の解剖学的変異と外科的影響を理解することは,下部頸椎手術にとって極めて重要です.
上部オモヒオイド腹を遮断すると,作戦計画が強化され,ACDFでの曝露を最適化することができます.
これらの発見を確認するために,標準化された結果測定法によるさらなる見通し研究が必要である.

The Hyoid Bone

The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Axial and Appendicular Muscles

Skeletal muscles, the key players in our body's movement, can be classified into two groups based on their location and function: axial muscles and appendicular muscles. These classifications reflect the primary roles the muscles play in the body's structure and movement.
Axial Muscles
Axial muscles, situated along the body's midline, are intricately connected to the axial skeleton, which includes the skull, spine, ribs, and sternum. These muscles facilitate facial expressions and play a...

Muscles of the Anterior Neck

The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Muscles that Move the Head

The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Muscles of the Shoulder

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Cranial Nerves: Types Part II

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
Facial Nerve (Cranial Nerve VII)
Cranial nerve VII, or the facial nerve,...
