Nasal Endoscopy

Preparation and Results of Nasal Endoscopy | ENT Specialist

What is nasal endoscopy?

Nasal endoscopy is a procedure to look at the nasal and sinus parts. This is done with an endoscope. It’s a slim, comfortable hose with a small chamber and light. An ear, nose, and throat doctor (otolaryngologist) often performs this procedure in their office.

The sinuses are a group of spaces made up of the bones in your face. They connect with your nasal cavity. This is the air-filled area behind your nose.

During the procedure, the doctor will place an endoscope in your nose. He or she will guide you through your nasal and sinus parts. Images of this area can be seen through an endoscope. Helps diagnose and treat health problems. In some cases, small instruments can be used to take small samples of tissue (biopsy) or to perform other tasks.

Indications of nasal endoscopy

Nasal endoscopy indications may include:

  • Diagnosis in patients with cyanosis symptoms such as facial pressure or pain, mucus discharge, decreased sense of smell, or nasal congestion or obstruction.
  • Evaluation of arbitrary diseases.
  • Assess the response to medical treatment in patients with antibiotics, antihistamines, oral steroids, or topical nasal steroids after treatment such as purulent secretions, inflammation, and resolution of mucous edema or polyps.
  • Evaluation of patients with upcoming complications of sinusitis.
  • Endoscopic functional debridement of the nasal sinuses and removal of mucus, scabs, and fibrin from the blocked sinus and nasal cavities after surgery.
  • Acquire a culture of purulent secretions.
  • Repeated evaluation of potential pathology after functional endoscopic sinus surgery (FESS).
  • Evaluation of the nasopharynx for eustachian tube problems, lymphoid hyperplasia, and nasal obstruction.
  • Evaluation and biopsy of nasal lesions or masses.
  • Evaluation of anosmia or hyposmia.
  • Evaluation of cerebrospinal fluid (CSF) leak.
  • Evaluation and treatment of nasal foreign bodies.
  • Evaluation and treatment of epistaxis

Why do you need nasal endoscopy?

An otolaryngologist may recommend a nasal endoscopy to diagnose nasal conditions, such as sinusitis (infection of the sinuses), nasal obstruction, nasal congestion, nasal polyps (non-cancerous growth in the lining of the nasal or sinus passages), as well as a variety of larynx. Injury (injury to the larynx).

How does nasal endoscopy work?

The doctor uses a device called an endoscope or a small scope. The endoscope is a thin, flexible tube with a small camera built into the end that holds the nose of the doctor. Since it is too dark for your nose, the scope also has a light at the end.

  • Nasal endoscopy can help your doctor find out why you have problems like a runny nose, facial pain, or earache.
  • If you are having trouble breathing or swallowing, nasal endoscopy can help doctors find out what is causing these problems.
  • Your doctor will also be able to see if you have a nose or sinus infection or if it is causing an obstruction, such as a polyp.

Risk factors of nasal endoscopy

Nasal endoscopy is generally safe. But in rare cases, these problems can occur:

  • Nosebleed
  • Fainting
  • Harmful reaction to the decongestant or anesthetic

There is a risk of bleeding, if you have a bleeding defect or if you take blood thinners. Your own risks may vary based on your age and your other health conditions. Ask your healthcare provider about the risks that apply most to you.

Nasal endoscopy preparation

Ask your healthcare provider if you stopped taking any medications before the procedure. Of these, the blood may be thinner. You should normally eat and drink before the procedure. Your healthcare provider can give you further instructions on what to do before the test.

Before the procedure, a topical decongestant may be sprayed into the nose. It helps reduce inflammation and allows the nasal endoscope to easily pass through the nasal cavity and sinuses. You can spray your nose with an anesthetic, which will briefly numb your nose. Healthcare providers should avoid these drugs in special circumstances. In some cases, you may even need an injection (shot) of the medicine.

During the test

First, apply decongestant and anticonvulsant medications to the nose. Next, your doctor will insert a narrow scope. Your doctor needs to examine the entire nasal area, including the sinuses. This will help us check your nasal septum and areas such as turbinates for abnormalities.

Also, it allows you to examine the area where the sinuses flow into the nose, the posterior nasal cavity, and the nasopharynx (the area where the adenoids are located) that are not really visible without this procedure.

After the procedure

Your healthcare provider can talk with you about the results before you go home. Or you can schedule an upcoming visit to discuss the results and treatment options. After the endoscopy, you can immediately return to your normal routine. Follow the instructions given to you.

To soothe the nasal passages, you may be advised to flush your nose with saline. If so, your healthcare provider will explain how to do it. Call your healthcare provider if you have a severe runny nose in the next few days.

What abnormal results mean

Nasal endoscopy helps with the diagnosis of:

  • Polyps
  • Blockages
  • Sinusitis
  • Swollen and runny nose that will not go away
  • Nasal masses or tumors
  • A foreign object (like a marble) in the nose or sinus
  • Deviated septum (many security plans need a nasal endoscopy before surgery to correct it)

Complications of nasal endoscopy

Most nasendoscopy is done without side effects or complications. There will be some pain in the nose and throat (pharynx) after about a day. Occasionally, the scope can cause sneezing, which stops immediately after the test. The endoscope can also occasionally cause slight bleeding from the nose. It usually stops very quickly.
