In speech pathology and medicine, nasoendoscopy is the endoscopic examination of the velopharynx, or the nose, often with a CCD camera or a fiber optic camera on a flexible tube passed through the nostril. It can provide information to evaluate speech and velopharyngeal function or dysfunction, as in diseases such as sinonasal carcinomas. [1] [2]
It is performed using a fiberoptic [1] instrument called a flexible fiberoptic nasopharyngoscope, [2] that is inserted through the nose in order to examine both it, and the back of the throat. [3] It is typically used to identify a variety of conditions including nasal septal deviation , polyps , and edema , [ 4 ] and the causes of conditions ...
A Storz endoscopy unit used for laryngoscopy exams of the vocal folds and the glottis. Basil Hirschowitz, Larry Curtiss, and Wilbur Peters invented the first fiber optic endoscope in 1957. [18] Earlier in the 1950s Harold Hopkins had designed a "fibroscope" consisting of a bundle of flexible glass fibres able to coherently transmit an image ...
In October 1903, Hirschmann published "Endoscopy of the nose and its accessory sinuses." [2] In 1910, M. Reichart performed the first endoscopic sinus surgery using a 7 mm endoscope. In 1925, Maxwell Maltz created the term "sinuscopy," referring to the endoscopic method of visualizing the sinuses. Maltz also encouraged the use of endoscopes as ...
An endoscopy is a procedure used in medicine to look inside the body. [1] The endoscopy procedure uses an endoscope to examine the interior of a hollow organ or cavity of the body. Unlike many other medical imaging techniques, endoscopes are inserted directly into the organ.
Introducing a flexible fiberoptic scope into the hypopharynx to obtain a view, the examiner may witness the collapse and identify weakened sections of the airway. Müller's maneuver is used to help determine the cause of sleep apnea .
Fiberoptic intubation under general anesthesia typically requires two skilled individuals. [38] Success rates of only 83–87% have been reported using fiberoptic techniques in the emergency department, with significant nasal bleeding occurring in up to 22% of patients.
A scanning fiber endoscope is a technology that uses a flexible, small (< 6Fr) peripheral or coronary catheter to provide wide-field, high-quality, full-color, laser-based video imaging. These differences distinguish SFE applications from current imaging approaches such as IVUS and Intracoronary OCT .
