Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA This video provides an overview of sinus, nose, and throat examinations. The demonstration begins with a brief overview of the anatomy of the region. The upper third of the nose is bony, and the bottom two-thirds are cartilaginous. Air entering the nares passes through the nasal vestibules and into the narrow passageway between the nasal septum...

Minimally invasive transverse aortic constriction (MTAC) conserves the essentials of regular transverse aortic constriction (TAC) while eliminating the use of a ventilator with tracheal intubation. It proves to be a highly desirable method for high-throughput studies on left ventricular overload, particularly in translational studies.
FAQs
The pathway’s geometry determines the direction of venous return: flow travels laterally through the transverse segment, then follows the sigmoid segment as it curves inferiorly. This continuity links the posterior cranial compartment with the skull’s jugular foramen exit. Understanding the change in direction helps clinicians interpret its course on anatomical studies and recognize where the pathway leaves the cranial cavity.
Because it lies alongside the posterior cranial fossa, cerebellum, and temporal bone, its course provides spatial orientation in a crowded skull-base region. These relationships help clinicians identify nearby structures and anticipate the sinus’s position when approaching the area. Its landmark value is especially important when surgery could expose, compress, or injure the venous pathway.
Thrombosis, narrowing, or injury are important because they may signal a problem along a major cranial venous route. The supplied context identifies recognition of these abnormalities as essential for diagnosing cerebrovascular disease and planning safe neurosurgical procedures. Their significance therefore extends beyond anatomy: they connect structural assessment with clinical evaluation and operative risk management.
Magnetic resonance venography and computed tomography provide ways to assess the pathway, although the supplied context does not assign a specific diagnostic advantage to either technique. Imaging can help evaluate concerns such as thrombosis or narrowing and show the relevant anatomical course. These findings support cerebrovascular assessment and provide information needed for neurosurgical planning.
During skull-base surgery, the sinus’s position relative to the posterior cranial fossa, cerebellum, and temporal bone becomes an operative consideration. Mapping that course during planning helps surgeons account for a major venous structure near the target region. Awareness of possible injury supports safer approaches, while imaging can help evaluate the anatomy and identify abnormalities.
In neuroscience, this pathway links regional anatomy, venous drainage, and cerebrovascular disease. Its course illustrates how structures in the posterior cranial fossa connect with an intracranial route leading toward an extracranial venous exit. Studying it supports neuroanatomical localization, interpretation of magnetic resonance venography or computed tomography, and skull-base surgical decision-making.
