Endoscopic evaluation of Nose and throat in clinic: Nasal endoscopy and Flexible laryngoscope

What is an Endoscopy?

An endoscopy is a procedure in which a doctor uses specialized instruments to view and operate your body’s internal organs and vessels. It is the Nonsurgical process in which doctors can view internal organs through the endoscope. An ENT specialist inserts an endoscope through your nose to examine the sinus openings and rule out any nasal problems like nasal polyps, sinusitis or nasal tumours. A flexible laryngoscope is an endoscope which is a flexible tube with an attached camera that allows the doctor to examine your voice box and evaluate your voice.

Why do I need an ENT endoscopy?

You may need an ENT endoscopy if you’ve had chronic problems with any of the following conditions:

What is nasal endoscopy?

Nasal endoscopy is a procedure to look at the nasal and sinus passages. It’s done with an endoscope. This is a thin, rigid tube with a tiny camera and a light. An ear, nose, and throat doctor (otolaryngologist) will often do this procedure in their office.
The sinuses are a group of spaces formed by the bones of your face. They connect with your nasal cavity. This is the air-filled space behind your nose.

During the procedure, the healthcare provider inserts the endoscope into your nose. They guide it through your nasal and sinus passages. Images of the area can be seen through the endoscope. This can aid in the diagnosis and treatment of health conditions. In some cases, small tools may be used to take tiny tissue samples or do other tasks.

Why might I need a nasal endoscopy?

You might need a nasal endoscopy if your healthcare provider needs more information about problems such as:

The endoscopy can show specific details, such as the site of bleeding and swelling of nasal tissue. It can also be used to look at cancer.

In some cases, a nasal endoscopy can be used as a treatment. For example, it may be done on a child to remove a foreign object from their nose.

Your provider might also advise endoscopy to see how treatment for a nose or sinus problem is working.

Rhinosinusitis is one of the most common reasons for nasal endoscopy. You may have symptoms such as nasal blockage, coloured fluid from your nose, and facial pain. Your healthcare provider can use the endoscope to look for swelling and polyps. They may collect pus from the infected area. This can help show what is causing an infection and how best to treat it.

A healthcare provider may use a nasal endoscope to do minimally invasive surgery. This is done in a hospital or surgery centre. It can treat sinus infections, nasal polyps, and nasal tumours. The surgery is done with small tools and does not need an external cut (incision).

Flexible laryngoscopy

Flexible laryngoscopy is a common procedure among otolaryngologists for assessing nasal, pharyngeal and laryngeal pathology, indispensable to modern ENT practice.

Indications for Flexible Laryngoscopy

Laryngoscopy may be indicated for the evaluation of patients with the following:

In particular, patients at high risk of head and neck cancer may benefit from laryngoscopy, especially if they have had hoarseness, sore throat, or ear pain for about 2 weeks.

Laryngoscopy can also be useful for evaluating the airway before orotracheal intubation.

Urgent laryngoscopy may be indicated in angioedema, stridor, epistaxis, and craniofacial trauma patients.

Flexible laryngoscopy can be tried for patients who do not tolerate direct laryngoscopy.
