What is meant by adenoids?
Everyone has heard about tonsils, but what are adenoids?
You can easily see your tonsils, but where are the adenoids?
Adenoids are lumps of spongy lymphatic tissue situated right at the back of the nose at the roof of the mouth. You may be able to see your tonsils by standing in front of the mirror and opening your mouth wide but adenoids are not so easily visible. ENT Specialists use special mirrors and endoscopes to visualize the adenoids. Adenoids are present from birth and can gradually increase in size to produce problems in children. It has mostly disappeared by the time your child is a teenager and for that matter adenoid problems are seen in children only.
Why does the adenoid enlarge?
Increase in size of the adenoid can occur on its own or due to inflammation [infection, allergy]
What are the effects of enlarged adenoids?
Since the adenoids are situated in the back of the nose and close to the orifice of the eustachian tube, adenoid hypertrophy or enlargement can have effects on the adjoining areas :-
Effect on Ear: The eustachian tube connects the middle ear to the nasopharynx [ back of the nose] and eustachian tube dysfunction can occur when there is adenoidal enlargement or when the adenoids are a seat of chronic infection. Eustachain tube dysfunction can lead to ear infection in children and fluid collection in the middle ear called glue ear. Fluid in the ear can produce hearing loss, ear discomfort, dizziness, tinnitus, aural fullness etc
Effect on the Nose and Sinuses: A large adenoids can block the back of the nose [called choanae] and produce nose block, nose congestion, collection of secretions, and increased nasal and sinus infections.
Effect on the Mouth and Throat: Enlarged adenoids produce mouth breathing in the child as a result of the nose block. Initially this may be only at night and parents will notice the child snoring .It is not normal for children to snore! In severe enlargement of the adenoids the child will breathe through the mouth in the day time also. Mouth breathing can affect the dentition of the child in an adverse way. When a child breathes in air through the mouth the important filtering and humidifying action of the nasally breathed air is lost and this predisposes the child to more frequent throat infections.
Effect on sleep and health: Since adenoids affect the normal breathing and this is more pronounced at night, sleep of the child may be affected with adverse effects on growth. In Sever cases sleep apnea can develop with serious effects on the lungs and even heart.

How is adenoids diagnosed?
Clinical Suspicion and Consultation
The layman’s knowledge about the adenoids is quite dismal in majority of the cases and even though you as a parent are concerned about your child’s health ready and reliable information about health and diseases is hard to come by! Since the signs and symptoms of adenoids are so ubiquitous often the general physician or pediatrician may fail to think about adenoids and it is indeed the astute clinician who suspects the condition and makes a timely diagnosis in your child.

If your child is cooperative a painless quick nasal endoscopy may be all that is required to clinch the diagnosis
Dr Sonia uses a real time video endoscope to visualize the adenoids situated at the back of the nose. Using endoscopy one can judge the presence of the adenoids, the amount of blockage produced by the adenoids and also assess for other contributing conditions in the nose such as turbinate hypertrophy, allergic mucosal swelling, nasal polyps, and deviated nasal septum. Using endoscopy we can even avoid taking an X-ray many a times.
Sometimes your child may require an X-ray of the Nasopharynx [area behind the nose where the adenoids are situated] to assess the presence and severity of adenoids.
An otoendoscope or otoscope is used by Dr Sonia to examine the ears: this will reveal the condition of the ear drum and the middle ear. Children with adenoid enlargement can have fluid in the middle ear and in long standing cases ear drum affliction in the form of retraction of the ear drum.
Hearing and Middle ear function Tests: These tests are simple tests ordered if there is suspicion of ear involvement in your child. In the young child even a mild hearing reduction can have severe consequences hence the need to promptly assess and treat such conditions.
