One of the most useful tools an ENT specialist uses to diagnose sinus and nasal problems is a nasal endoscopy.
Many patients are surprised at how quick and helpful this procedure is. A nasal endoscope allows your ENT doctor to see areas deep inside the nose and sinuses that simply cannot be evaluated well with a regular flashlight exam.
At SCENT Houston, Dr. Madeleine S. Herman frequently performs nasal endoscopy to evaluate nasal congestion, sinus infections, nasal obstruction, allergies, postnasal drip, loss of smell, and more.
What Is a Nasal Endoscopy?
A nasal endoscopy is a procedure where a thin camera called an endoscope is gently inserted into the nose to examine the nasal passages and sinus openings.
The procedure:
Is performed in the office
Usually takes only a few minutes
Does not require sedation
Is generally very well tolerated
Most patients describe it as mildly uncomfortable at most.
Why Would an ENT Perform a Nasal Endoscopy?
Nasal endoscopy helps diagnose many common ENT conditions, including:
Chronic sinus infections
Nasal obstruction
Deviated septum
Nasal polyps
Allergies
Postnasal drip
Nosebleeds
Loss of smell
Chronic congestion
Sinus headaches
It allows your ENT physician to get a much more detailed view than a standard exam.
What Does an ENT Look For During a Nasal Endoscopy?
1. Deviated Septum
The septum is the wall dividing the two sides of the nose. If it is crooked or deviated, it can block airflow and contribute to congestion, snoring, and sinus problems.
An ENT evaluates:
Severity of the deviation
Areas of blockage
Impact on breathing and sinus drainage
2. Nasal Polyps
Nasal polyps are soft inflammatory growths that can block airflow and sinus drainage.
During endoscopy, your ENT looks for:
Presence of polyps
Size and location
Signs of chronic inflammation
Polyps are commonly associated with chronic sinusitis and allergies.
3. Signs of Infection or Inflammation
An ENT examines the nose and sinus drainage pathways for:
Swelling
Thick mucus
Pus or infection
Redness and inflammation
These findings may suggest chronic sinusitis or active infection.
4. Turbinate Enlargement
Turbinates are structures inside the nose that help humidify and filter air.
When enlarged, they may contribute to:
Chronic congestion
Difficulty breathing through the nose
Snoring
Your ENT evaluates the size of the turbinates and their contribution to blockage.
5. Sinus Drainage Pathways
The sinus openings are carefully examined to look for:
Blockage
Swelling
Polyps
Poor drainage
This is especially important in patients with recurrent sinus infections or chronic sinus pressure.
6. Sources of Nosebleeds
In patients with recurrent nosebleeds, nasal endoscopy helps identify:
Irritated blood vessels
Areas of dryness
Crusting
Less commonly, abnormal growths
7. Signs of Allergies
Allergic inflammation inside the nose may appear:
Pale
Swollen
Boggy
Mucus-filled
Nasal endoscopy can help determine whether allergies may be contributing to symptoms.
8. Masses or Abnormal Growths
Although uncommon, ENT specialists also evaluate for:
Tumors
Unusual masses
Structural abnormalities
Persistent one-sided blockage or bleeding may require further evaluation.
Is Nasal Endoscopy Painful?
Most patients tolerate nasal endoscopy very well.
A topical numbing spray and/or decongestant may be used beforehand to improve comfort.
Patients often say:
“That was easier than I expected.”
“It just felt a little strange.”
“It wasn’t painful.”
When Should You Have a Nasal Endoscopy?
Your ENT may recommend nasal endoscopy if you have:
Chronic nasal congestion
Recurrent sinus infections
Difficulty breathing through your nose
Loss of smell
Postnasal drip
Persistent sinus pressure
Nosebleeds
Snoring or sleep issues
