Adenoid Surgery (Adenoidectomy): Diagnosis And Tests

Seeing the Invisible Obstruction

Diagnosing adenoid problems presents a unique challenge: the adenoids are hidden behind the soft palate and cannot be seen by simply looking in the mouth. A pediatrician might suspect adenoid issues based on symptoms like mouth breathing or snoring, but confirming the diagnosis requires specialized visualization.

At LIV Hospital, our ENT Department uses a “gentle diagnostics” approach, especially since our patients are primarily children. We utilize tools that allow us to see the size and condition of the adenoid pad without causing distress. Our goal is to determine not just if the adenoids are large, but how much they are obstructing the airway and whether they are contributing to ear infections or sleep apnea.

Common Screening Tests for Adenoid Hypertrophy

EAR NOSE THROAT

The evaluation begins with a standard physical exam. While the doctor cannot see the adenoids directly, they look for the secondary signs of obstruction.

  • Nasal Exam: The doctor uses a light to check inside the nostrils for other causes of blockage, such as a deviated septum, nasal polyps, or swollen turbinates (allergy signs).
  • Ear Exam (Pneumatic Otoscopy): The doctor puffs a small amount of air into the ear canal to see if the eardrum moves. If the eardrum is stiff or fluid is visible behind it (“glue ear”), it suggests the adenoids are blocking the Eustachian tubes.
  • Oral Exam: We look at the tonsils and the shape of the palate. A “high arched palate” is a structural sign of long-term mouth breathing caused by adenoids.

Advanced Diagnostic Procedures

EAR NOSE THROAT

To see the adenoids directly, we use advanced imaging and optical tools.

  • Nasopharyngoscopy (Flexible Endoscopy): This is the gold standard for adenoid diagnosis. It involves passing a tiny fiber-optic camera through the nose to look at the back of the throat. It gives a live, color view of the adenoid tissue.
  • Lateral Neck Radiograph (X-Ray): For children who cannot tolerate the camera, a soft tissue X-ray of the neck is a reliable alternative. It provides a side-view profile of the airway, showing the shadow of the adenoids blocking the air passage.
  • Tympanometry: This is a pressure test for the middle ear. It confirms if the adenoids are causing negative pressure or fluid buildup, even if the infection isn’t currently active.

What to Expect During Nasopharyngoscopy

Parents often worry about the nasopharyngoscopy procedure, but it is quick and generally well-tolerated.

  • Numbing: First, we spray the child’s nose with a combination of a decongestant and a local anesthetic. This shrinks the nasal tissue and numbs the sensation.
  • Insertion: The doctor gently inserts a flexible tube (about the size of a spaghetti noodle) into the nostril.
  • Visualization: The camera is guided to the back of the nose. The parent can often watch on a screen as the doctor points out the adenoid tissue blocking the airway.
  • Sensation: It is not painful, but it feels “weird.” Children describe it as a tickle or the feeling of needing to sneeze. The exam takes less than 2 minutes.

How to Prepare for Nasopharyngoscopy

Preparation is mostly about comfort and cooperation.

  • No Fasting Required: Since this is a clinic procedure and not surgery, your child can eat and drink normally beforehand.
  • Explanation: Tell your child the doctor has a “cool camera” to look at their nose. Avoid words like “pain” or “hurt.”
  • Holding Technique: For younger children, parents may need to hold them in a comforting hug (the “papoose” hold) to keep their hands and head still during the exam.
  • Nasal Hygiene: If the child has a very runny nose, gently suctioning it before the appointment helps the doctor see better.

Understanding Your Test Results

The doctor will grade the size of the adenoids based on the endoscopic view or X-ray.

  • Grade 1: Adenoids cover less than 25% of the airway (choana). Usually not a problem.
  • Grade 2: Adenoids cover 25-50% of the airway.
  • Grade 3: Adenoids cover 50-75% of the airway. This often causes symptoms.
  • Grade 4: Adenoids cover 75-100% of the airway. This is a complete obstruction and strongly indicates the need for surgery.

When Do You Need Polysomnography?

In some cases, the adenoids look large, but we need to prove they are dangerous. A Sleep Study (Polysomnography) is the most advanced test for sleep apnea.

  • The Process: The child spends a night in our sleep lab with sensors monitoring breathing, oxygen levels, and heart rate.
  • The Indication: We order this if the child has complex medical conditions (like Down Syndrome), is obese, or if the size of the adenoids doesn’t seem to match the severity of the snoring symptoms.
  • The Outcome: This test provides concrete data on how many times the child stops breathing per hour (AHI score), which helps justify the need for surgery to insurance providers and parents.

FREQUENTLY ASKED QUESTIONS

What tests are used to diagnose adenoid issues?

The most common tests are Nasopharyngoscopy, where a small camera looks up the nose, and Lateral Neck X-rays, which show a shadow of the enlarged tissue. Doctors also use tympanometry to check if the adenoids are affecting ear pressure.

There is no physical preparation like fasting. The most important part is mental preparation. Explain to your child what will happen calmly. You may be asked to hold your child on your lap to keep them still. We will use a numbing spray to make the nose comfortable before the test begins.

No, it is generally not painful. The local anesthetic spray numbs the inside of the nose effectively. Most children report a sensation of pressure, tickling, or the urge to sneeze. It is a very quick procedure, usually lasting only a minute or two.

Endoscopy is extremely accurate (over 90%) because it allows direct visualization of the obstruction. X-rays are slightly less accurate as they only show a 2D shadow, which can change depending on how the child breathes during the picture, but they are still a very useful screening tool.

You need a Sleep Study (Polysomnography) if your child has signs of sleep apnea (stopping breathing), but the tonsils and adenoids don’t look very big on the exam. It is also standard for children with obesity or other health conditions to ensure surgery is safe and necessary.
