Imaging of the infrahyoid neck

Area of Science:

• Anatomical studies
• Surgical anatomy
• Head and neck pathology

Background:

• The infrahyoid neck presents complex anatomical and pathological challenges.
• Accurate spatial understanding is crucial for diagnosing and managing conditions in this region.

Purpose of the Study:

• To delineate the six discrete anatomical spaces within the infrahyoid neck.
• To characterize pathological processes based on fascial planes.
• To review the anatomy and pathology of the thyroid, parathyroid glands, and brachial plexus.

Main Methods:

• Detailed anatomical dissection and review of deep cervical fascia layers.
• Correlation of anatomical spaces with common pathologies.
• Review of relevant medical literature and imaging findings.

Main Results:

• The deep cervical fascia divides the infrahyoid neck into six distinct anatomical spaces.
• Pathological processes can be better understood and localized within these defined spaces.
• Comprehensive review of thyroid, parathyroid, and brachial plexus anatomy and pathology provided.

Conclusions:

• A systematic understanding of the infrahyoid neck's compartmentalization is essential for accurate diagnosis and treatment.
• This anatomical framework aids in characterizing and managing diverse pathologies in the region.
