Summary
Neck tissue shifts during surgery, especially for major vessels like the common carotid artery, are non-linear with head rotation. Understanding these deformations aids surgical navigation.
Area of Science:
- Medical imaging
- Surgical navigation
- Anatomy
Context:
- Neck surgery requires specific patient positioning, leading to significant neck tissue deformation.
- Preoperative imaging data is crucial for effective medical navigation during these procedures.
Purpose:
- To analyze and quantify neck tissue shifts during head rotation in patients undergoing neck surgery.
- To understand the relationship between head rotation and tissue displacement for improved surgical planning.
Summary:
- Magnetic Resonance Tomography (MRT) images from 5 patients revealed non-linear tissue shifts with head rotation.
- Major vessels contralateral to rotation shifted more than ipsilateral ones; internal jugular vein shift was less than common carotid artery shift.
- Tissue movement was more pronounced in the cranial compared to the caudal neck sections.
Impact:
- Findings provide essential data for intraoperative navigation systems in minimally invasive neck surgery.
- Accurate knowledge of tissue shifts can enhance surgical precision and patient outcomes.
- Facilitates online calculation of tissue shifts for real-time surgical guidance.

01:19Muscles 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...

01:28Articulations of the Vertebral Column
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
