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]
Endoscopic endonasal surgery is a minimally invasive technique used mainly in neurosurgery and otolaryngology.A neurosurgeon or an otolaryngologist, using an endoscope that is entered through the nose, fixes or removes brain defects or tumors in the anterior skull base.
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 simple procedure that allows a doctor to look inside human bodies using an instrument called an endoscope. A cutting tool can be attached to the end of the endoscope, and the apparatus can then be used to perform minor procedures such as tissue biopsies, banding of oesophageal varices or removal of polyps.
rigid endoscope: A rigid endoscope is a prismatic optical system with advantages of clear imaging, multiple working channels and multiple viewpoints. flexible endoscope: A flexible endoscope is an optical-fiber-based system. Notable features of a flexible endoscope include that the lens can be manipulated by the operator to change direction ...
Nasal endoscopy involves passing a small, rigid camera with a light source into the nose. An image is projected onto a screen in the office so the doctor can examine the nasal passages and sinuses in greater detail.
In posterior rhinoscopy, the endoscope is advanced through the mouth to examine the back of the nasal cavity above the soft palate, and can be used to visualise the oropharynx below that. Structures seen in posterior rhinoscopy: posterior border of nasal septum, fossa of Roosenmuller, eustachian tube opening and upper surface of soft palate.
Bronchoscopy is an endoscopic technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument (bronchoscope) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy.
