Evaluation of Child with Nose Block, Snoring and Restless Sleep

With increasing awareness about sleep apnea child is increasingly being refereed to otorhilnolaryngologist (E N T specialists) by pediatricians to evaluate the cause of nose block, snoring and restless sleep.

Nasal blockage is the sensation of reduced air flow either through one nostril (unilateral) or both nostrils (bilateral).

It is common thinking amongst people that blocked nose (congested or stuffy nose) is because of thick mucus and they try to blow it out. But it is wrong thinking.

Nasal block is a common complaint in children and it usually resolves without treatment. However it may cause a significant problem with abnormalities in teeth and face as well as heart and lung of child. Nasal block can interfere with the ears, hearing, and speech development. In first few months of life it can interfere with feeding and cause life threatening problems.

Thus every nasal block and mouth breathing in children should be evaluated carefully and potential serious causes must be considered in the differential diagnosis.

Causes of Nose Block

There are many different causes of nasal obstruction. Some causes are present at birth (congenital), oOther causes are acquired later in life.

Infectious/inflammatory mucosal swelling

  • Allergic rhinitis
  • Chronic rhino-sinusitis

Structural problems

  • Enlarged Adenoids
  • Deviated nasal septum (DNS)
  • Enlarged turbinate
  • Nasal polyps

Foreign Body nose


  • Posterior choanal stenosis/atresia
  • Encephalocele/meningoencephalocele
  • Craniofacial deformities
  • Dermoids/Craniopharyngiomas/Teratomas/Chordomas
  • Nasoalveolar and Nasopharyngeal (Tornwaldt’s) cysts

Evaluation of a child with nose block

The goals of the evaluation are to determine specific causes of problems, the severity of the obstruction, and the presence of associated medical complications.

This is achieved by thorough history of symptoms and clinical examination of nose along with endoscopic examination of nose and nasopharynx.

Examination of nose of a young child can be done by simply tilting the tip of the nose upwards or using an otoscope.  An extensive examination of nose is often difficult and not possible.

Following diagnostic tests based on clinical findings may be advised:-

  • Allergy skin tests
  • Blood tests (such as CBC)
  • Sputum culture and throat culture
  • X-rays of the sinuses, Nasopharynx and chest
  • Serum total IgE

Differential diagnosis

Rhintis –

Nasal mucosa is thin pinkish lining that covers inside of the nose.  Swelling or inflammation of this mucosa can be caused by allergies, irritants (smoke and pollution), infection, hormonal (vasomotor rhinitis) and abuse of nasal drops (rhinitis medicamentosa).

Careful history and evaluation of the nose (nasal endoscopy for detailed examination) is all that is required to find out the likely diagnosis. Sometimes, additional tests may be advised to confirm the cause.

Usually medical treatment along with antibiotics and steroid nasal spray are required along with preventive measures to avoid allergen/irritants.

Allergy shots are successful treatment method. SLIT skin tests and sometimes blood tests are used to make allergy-inducing substances specific to an individual patient.

Chronic sinusitis is evaluated by CT scan during the quiet periods. A very conservative approach is followed as far as children are concerned. If patient fails to respond to medical treatment endoscopic sinus surgery may be necessary.

Deviated Nasal Septum (DNS)

Nasal septum is mid line partition which divides the nose into two halves. Child may be born with a deviated septum, or may develop after injury to nose.

Clinical examination by headlight and mirror is enough to conform the diagnosis, nasal endoscopy may be done for detailed examination of nose to rule out other anatomical abnormalities inside the nose and nasopharynx.

Sometimes DNS does not cause any symptoms but if it is severe enough to block the nasal passage it is to be corrected with surgery of septum (septoplasty)

Adenoid Enlargement

Second most common cause of nose blockage is enlarged or hypertrophied adenoids. Adenoids are lymphoid tissue similar to tonsils situated at back space of nose.

Adenoids are not directly visible and mirror examination or nasal endoscopy is required to see it. X-ray of nasopharynx may be done to see the enlarged adenoids.

If adenoids are blocking nasal airway leading to sleep apnea it has to be removed surgically.

Foreign Body Nose–

A common cause of nasal obstruction in the younger child is an object (foreign body) placed in the nose (such as peanut, seeds, beads, button cell).

Characteristic history usually raises strong suspicion. Child usually comes with a foul smelling drainage from the nose on the side of the foreign object.

Removal can be done in the office without anesthesia but occasionally, if the foreign body has been present a long time, a short general anesthesia is necessary to remove it.

Congenital  Malformations

Choanal atresia (back opening of the nose is blocked with either tissue or bone), if bilateral (both sides are involved) surgical repair is needed immediately to allow the child to breath normally. If only unilateral (one sided) the diagnosis may be made much later in life.

Tumors such as nasal dermoids, chordoma and craniopharyngiomas most often present during infancy and early childhood however, they may be missed early in life.


In summary, chronic nasal obstruction in children is a common symptom that requires careful evaluation, a correct diagnosis and treatment plan. Both the diagnostic evaluation and the treatment must take into account not only the nature and severity of the primary disease, but also the possible adverse effects on hearing, facial growth as well as cardiac and pulmonary systems.

Tonsils and Adenoids: Mouth Breathing and Snoring in Children

As otolaryngologists, we are frequently asked to evaluate the upper airway, especially by the dentists  in children undergoing orthodontic treatment or by pulmonologist in children undergoing evaluation for sleep disorders. While assessing the upper airway parents are asked few questions.

  • Does your child keep his mouth open, especially while asleep?
  • Does your child snore at night?
  • Does he have repeated colds and coughs?

Under normal condition, breathing takes place by the nose. Mouth breathing or snoring should not be overlooked and proper evaluation is to be done. Mouth breathing syndrome may cause abnormal positioning of teeth, and facial deformity.  It May progress to sleep disorder and poor school performance and in some cases lead to adverse effects on heart and lungs.

Mouth breathing and snoring due to adenoid is common in children, but since the signs and symptoms of adenoids are so ubiquitous, often the general physician or pediatrician may fail to think about adenoids.

Nose block may be of three types–

a. Organic—some mechanical obstruction –enlarged adenoids, tonsils, deviated nasal septum, allergic rhinitis, nasal foreign bodies, enlarged nasal turbinates, Nasal polyps etc.

b. Functional

c. Neurological

Adenoids and Tonsils

Tonsils and adenoids are clumps of lymphoid tissue, the tonsils are located on both sides of the back of the throat (Oropharynx) and adenoids are located higher in the passage that connects the back of the nose to the throat (Nasopharynx).

The tonsils are visible through the mouth, but the adenoids are not directly visible. A small mirror or a nasal endoscope is used to see the adenoids.

Role of the Adenoids/Tonsils:

Tonsils and adenoids trap bacteria and viruses entering through the throat and nose and produce antibodies to help the body fight infections. But they are not considered to be very important as our body has other means of preventing infection and fighting off bacteria and viruses.

Children are born with adenoids which are quite small and usually the adenoids shrink after about 5 years of age, and it practically disappear by the teenage years.

Some children (and adults) are prone to develop infections of the tonsils and adenoids. These infections can be caused by different kinds of bacteria other than streptococcus( the one most people know about).

Symptoms of enlarged tonsils and adenoids

Adenoids enlarge because of repeated allergy or infection. Children with enlarged tonsils or adenoids may have a sore throat and discomfort or pain during swallowing.

Enlarged or hypertrophied adenoids can block a child’s nasal passages and result in–

  • Nasal block and Difficulty breathing through the nose

Diagnosing tonsillitis and the enlarged Adenoids—

Most common cause of nasal obstruction in children is enlarged adenoids but nasal allergy may be contributing factor which should also be ruled out and managed.

Proper history and clinical examination are very important.

Number of episodes of sore throat during the past 1 to 3 years is more important than the size of the tonsils alone. Very large tonsils may be normal and chronically infected tonsils may be normal-sized.

Redness of the tonsils, enlargement of lymph nodes in the neck, and the effect of the tonsils on breathing is also assessed.

Parents may neglect open mouth of the child while sleeping, considering it normal or habitual but actually it may be an indication of sleep apnea.

Sometimes Parents may report that child has restless sleep indicated by moving around in bed or the child stops breathing frequently during sleep.

History of Dry mouth may be found on probing. The child may be hyperactive and have poor performance in school and may be falsely labeled as ADHD (attention deficit hyperactive disorder).

Patient may have a high arched palate and overcrowding of teeth, change in the face called adenoid facies.

Investigations to diagnose Tonsillitis and Adenoids

The tonsils are visible through the mouth, but the adenoids are not directly visible.

To view Adenoids post nasal mirror or nasopharyngoscopy (Rigid or fibreoptic) is usually required. Nasenendoscopy is reliable in assessing the size of the adenoids.

X-Ray of soft tissue of nasopharynx / Occasional CT scan is done.

Observation or Video recording of a child while sleeping may be helpful.

Polysomnography (Sleep Study) may be advised to see oxygen levels in the blood.


Why to remove the Tonsils and adenoids?

Tonsil surgery is less common now. The tonsils are normally large during childhood and begin to shrink in size after the age of 7-8 years.

Children who benefit from Tonsil surgery include those with the following:-

  • Obstructive sleep apnea
  • Extreme discomfort when talking and breathing
  • Lack of weight gain: Children may not eat sufficiently because of pain
  • Multiple throat or ear infections (Seven or more infections in 1 year, five or more infections a year over 2 years, or three or more a year over 3 years)
  • Chronic or recurrent tonsillitis associated with the streptococcal sore throat not responding to beta-lactamase-resistant antibiotics
  • Persistent foul taste or breath due to chronic tonsillitis not responsive to medical therapy

The only treatment for enlarged obstructing adenoids is to surgically remove them. Antibiotics and other medications do not help.

Though adenoids usually shrink in the second decade of life, however, blockage and sleep apnea may affect growth and development and cause permanent changes in facial or dental development. Decision to remove adenoids is usually taken before it occurs.

Adenoidectomy is recommended for the following:

  • Recurring nasal congestion and sinus infections
  • Blockage of back of nose :- Enlarged adenoids may cause “mouth breathing”, snoring, or sleep apnea (stop breathing for brief periods during sleep). Because of the blockage of upper airway, oxygen levels in the blood may be low, and children may wake up frequently and feel sleepy during the day. Rarely, obstructive sleep apnea can cause serious effects on lung and heart.
  • Chronic ear infections and hearing loss: -Adenoids block eustachian tubes (tube connecting back space of nose to the middle ear) resulting in fluid accumulation in the middle ear.
  • lack of weight gain: -Children may not eat sufficiently because of pain or because breathing takes constant physical effort


Surgery to Remove Adenoid and Tonsils

Usually surgery is under general-anaesthesia and child will not be allowed to eat or drink minimum 6 hours before surgery start time, and the patient doesn’t feel any pain during surgery.

Tonsils and the adenoids are removed through open mouth —no need to cut through skin.

Adenoids– traditional curettage method, endoscopic shaver, electrocautery or suction coagulator

Tonsil -Cold blunt dissection method, Bipolar Diathermy, LASER or Radio frequency

Complications  of tonsils and adenods surgery:

Anesthetic risk -serious anesthetic complications can occur, but are very unusual.  Bleeding is rare.

The Tonsillar and adenoid bed usually becomes superficially infected, and can cause 7-10 days of bad breath, but serious infections are very rare.

Adenoids should be removed with careful consideration and examination to avoid effects on speech and/or swallowing.  To be avoided in achild with sub mucous cleft palate.

Bleeding is a potential complication of tonsillectomy and before embarking on surgery family history of any abnormal bleeding should be excluded and patient’s coagulation profile is to be examined.

To conclude–

  • Tonsillectomy and adenoidectomy are usually done on an outpatient basis. These operations should be done at least 3 weeks after any infection has cleared to avoid risk of complications.
  • Removing the adenoids can help reduce snoring, but may not completely cure it because several other reasons may be responsible for snoring.
  • Tonsillectomy and adenoidectomy do not appear to decrease the frequency or severity of colds or cough.
  • Voice may sound different for a short while after the operation because of swelling in the area. However, this usually comes to normal within 1 or 2 weeks.
  • Removing the tonsils or adenoids does not cause any problems with the immune system.

White patches on the tonsils are mistaken for an infection. Most often this is of no medical significance. Furthermore, large tonsils do not necessarily mean the child needs to have them removed. The most common reasons to consider removal of the adenoids and tonsils are recurrent infections and obstructive sleep apnea (OSA).  Adenoidectomy has tremendous benefits for child’s health and is essential to safeguard child’s breathing and hearing.
