The StealthStation ENT system provides enhanced visualization to surgeons and also offers new software and hardware innovations including Virtual Endoscopy
, which provides a simulated view of sinus cavities previously inaccessible with a traditional endoscope.
can be loaded with the patient's preoperative data to allow the surgeon to practice an individual's surgery before he or she enters the surgical suite.
The basics of the various modalities used to image the larynx including x-ray, CT, MRI, xeroradiography, fluoroscopy, and PET-CT are described well elsewhere, as are the exciting technologies of virtual endoscopy
and virtual dissection.
In particular, the use of multiplanar reformats and 3D volume renderings, with or without virtual endoscopy
, can improve assessment of laryngeal framework fractures, arytenoid subluxation, and laryngotracheal narrowing, thereby providing helpful information for optimal management.
