It is defined as the visual examination of a cavity organ using the endoscope. The endoscope is a thin tube (rigid or flexible) equipped with a series of lenses and illuminated by fiber optics. The outer end of this tube can be attached to a camcorder connected to a monitor. Thus, the examined area is viewed on the monitor.
- Confirmation/rejection of the presence of rhinosinusitis by highlighting muco-purulent secretion in the middle meatus.
- Diagnosis of nasal polyposis
- Confirmation/rejection of the presence of obstructive adenoid vegetation
- Confirmation/rejection of rhinopharyngeal tumor pathology (especially young people with chronic unilateral otitis)
- Diagnosis of functional dysphonia, laryngitis, vocal nodules, gastroesophageal reflux disease with pharyngeal laryngeal reflux, rhinopharyngeal tumor pathology, vocal cord paralysis
Oto-endoscopy is an extremely useful exploration in the outpatient evaluation of the ear. The only requirement that the patient must meet during the examination is to remain still. The examination is not painful and does not require prior local anesthesia. The endoscope offers a wide field of view, the eardrum can be examined entirely and its mobility can also be evaluated. The presence of fluid in the middle ear can be visualized much better with the endoscope than with the otoscope, and the integrity of the middle ear tufts can be assessed through the perforated eardrum. Otto-endoscopy offers a better visualization of retraction bags compared to conventional otoscopy, offers a better evaluation of the operated ear and post-mastoidectomy cavities (operation for cholesteatoma). It is also an extremely useful tool in performing outpatient procedures such as: auricular toilet, extraction of the impacted cerumen plug, aspiration of ear secretions (otitis), removal of foreign auricular bodies.
Nasal endoscopy offers a detailed examination of the nostrils and the rhinopharynx. The most common reasons for this examination are nasal obstruction, suspected acute or chronic sinusitis, nasal/facial pain, odor disorders, and epistaxis. This test allows a full and detailed view of nasal mucous, nasal cornets, communication with para-nasal sinuses and rhyno-pharinx.
Rigid laryngeal endoscopy
It allows for a detailed view of the larynx and the lower portion of the pharynx. The procedure is performed with the patient in a sitting position. The lens of the endoscope, oriented lower oblique, will allow the visualization of the larynx and the hypopharynx.
It allows the evaluation of nostrils, pharynx and larynx with a small flexible tube. It can be used for examining nostrils, but is most often used for visualizing the larynx.
