The facet joints, also known as zygapophyseal joints, represent crucial articulations between vertebral segments that guide spinal movement while maintaining stability. These specialized synovial joints demonstrate complex biomechanical properties that vary by spinal region, making their understanding essential for medical professionals involved in spine care and surgery.

The thoracic region of the spine demonstrates complex ligamentous attachments that are crucial for maintaining stability while enabling respiratory movement. These specialized ligamentous structures coordinate with osseous elements to create a sophisticated system that balances mobility with structural integrity. Understanding these relationships is essential for medical professionals involved in treating thoracic spine conditions.

Radiological assessment of paranasal sinuses remains a cornerstone in modern otorhinolaryngology, providing crucial insights into sinonasal pathologies and guiding therapeutic decisions. The Caldwell view, a fundamental projection in sinonasal imaging, serves as an essential diagnostic tool for evaluating frontal and ethmoid sinuses while offering valuable information about orbital structures and nasal cavity anatomy.
