The trachea, commonly known as the windpipe, is a vital component of the respiratory system that connects the larynx to the bronchial tree and lungs. This cylindrical, cartilaginous tube serves as the main conduit for air passage during respiration, facilitating the movement of air to and from the lungs. The anatomical structure of the trachea is specifically designed to maintain airway patency while allowing flexibility during neck movements and swallowing. Understanding the detailed anatomy of the trachea and its relationship with surrounding structures is essential for medical professionals, particularly in contexts of airway management, respiratory diseases, and surgical interventions involving the thoracic region. This comprehensive illustration depicts the trachea in its anatomical context, showcasing its continuous pathway from the larynx to its bifurcation at the carina, where it divides into the primary bronchi leading to each lung.

In pediatric radiology, encountering rare anatomical variations alongside acute respiratory conditions presents unique diagnostic challenges. Situs inversus totalis, a congenital condition where major visceral organs are reversed from their normal positions, requires careful interpretation of radiological findings, particularly when complicated by acute respiratory infections. This case study examines a 3-month-old male patient presenting with significant respiratory symptoms and the radiological implications of this anatomical variation.

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.
