Ear, Nose & Throat: Pediatric Otolaryngology - Head and Neck Surgery

We provide care for children with disorders of the ears, nose and throat.
Our Program
The Division of Pediatric Otolaryngology provides care for children with disorders of the ears, nose and throat. These disorders can be congenital or acquired. The otolaryngologists care for a vast area of disorders, including:
  • ear infections
  • hearing loss
  • airway obstruction
  • obstructive sleep apnea
  • tonsillitis 
  • nosebleeds
  • sinus infection
  • voice disorders
  • salivary gland diseases
  • thyroid lumps
  • abnormally-shaped ears
  • congenital cysts
  • sinuses and fistulae of the head and neck
  • foreign bodies
  • tumors of the ear, nose, sinuses, neck, salivary glands, thyroid, larynx, trachea, and skull base.
Surgery ranges from relatively minor, such as myringotomy and tympanostomy tube insertion, adenoidectomy and tonsillectomy, to complex major procedures of the head and neck, such as cochlear implantation, mastoidectomy, bronchoscopy using balloons and lasers, open laryngeal reconstruction, neck or thyroid tumor removals, and endoscopic skull base surgery.

Every year, many thousands of children are assessed and treated through the Pediatric Otolaryngology (Ear, Nose and Throat) Clinic, including children referred from across British Columbia, the Yukon, and beyond. In addition, the team members participate in a number of multi-disciplinary clinics with other colleagues from across the campus, for example, cleft lip and palate, craniofacial, vascular anomalies, home ventilation and tracheostomy, complex aerodigestive disorders, esophageal atresia, thyroid, cochlear implantation, and bone conduction implantation.

You can find more information and resources in the Family Resource Library and about choking prevention and safe feeding through the Safe Start Program.

An adenoidectomy is a surgery performed to remove the adenoids. Adenoids are pads of tissue located high in the throat at the back of your child’s nose. Adenoidectomy may be considered if it impacts your child’s breathing, or if there are repeated infections. 

For information on how to care for your child after the surgery, please see the following handout:

A bone conduction hearing aid works by sending sound to the inner ear using sound vibrations through the bone. Bone conduction hearing aids may be considered for children with conductive hearing loss, or if a regular hearing aid does not work for your child. 

There are several types of bone conduction hearing aids.

  • BC Family Hearing Resource Society: Support for BC families 
Sports, injuries, or falls can cause a nasal fracture, also called a broken nose. A closed nasal fracture reduction is a procedure that moves your child’s nose back to its original position. It’s important to do this procedure in a timely manner, waiting too long can cause the bones to set irregularly.

The cochlea is a part of the inner ear. It turns sound vibration into neural messages that stimulates the hearing nerve. The hearing nerve sends messages about the sound to the brain. 

A cochlear implant is a device that directly stimulates the hearing nerve. It uses electrodes to capture vibrations and send messages to the hearing nerve.

A cochlear implant may help if your child has severe to profound sensorineural hearing loss. These implants can also help when regular hearing aids do not. 

During a surgery, a doctor inserts the implant into the cochlea, and implants a receiver behind the ear.

For more information on how to care for your child after the surgery, please see the following handout: Cochlear Implant Handout.pdf

Ear tube surgery is also known as a myringotomy and tympanostomy tubes surgery. The doctor makes a small opening in the eardrum, then ear tubes are placed to let fluid drain out of the middle ear. An ear tube is like a tiny straw. It is usually 2-3 mm long and can only be seen in the ear with special equipment. The ENT doctor may suggest tubes if your child has had a number of ear infections, or if the build-up of fluid appears to impact their hearing.

A Functional Endoscopic Sinus Surgery (FESS) is a surgery done to unblock the sinus openings into the nose. This may ease the pressure and pain from blocked sinuses. Surgery is sometimes considered after patients have tried other treatments. During the surgery, the ENT doctor will place a telescope with a special light system that allows them to zoom in and see the sinus openings.

A laryngoscopy and bronchoscopy are examinations that use a scope to look at parts of the airway. During this procedure, the doctor examines your child’s mouth, throat, voice box (larynx), windpipe (trachea) and finally the passages that lead to each lung (bronchial tubes). Your child will be under anesthesia for this procedure. 

For information on how to care for your child after the procedure, please see the following handout:

Otoplasty is a surgery performed to reshape the ears. It may be considered if the child is born with prominent ears. Your child will have a bandage around their head for 7-10 days.

Some babies are born with small skin tunnels that open in front of, or inside, the ear. These are called "preauricular sinuses". These tunnels result when tissues forming the ear do not fuse completely. No one knows why this happens or why it happens more often in girls than boys. No treatment is needed unless these tunnels become infected. If they do, the doctor may recommend surgery to remove them.

Recurrent Respiratory Papillomatosis (RRP) is a rare disease in which benign (non-cancerous), wart-like tumours grow inside the larynx (voice box), vocal cords, and in a few cases, inside the windpipe. The first sign is a hoarse voice. New papillomas tend to keep growing, unless they are removed. Most people with this problem need to have the growths removed each time they grow larger; if left, they may block the airway and make it impossible to breathe. The surgeon removes the growths while the child is under an anesthetic.

A Salivary Gland Duct Ligation is offered mostly for patients who have tried other therapies and have not been successful in decreasing the amount of drooling. This surgery involves tying-off of the 2 submandibular and the 2 parotid gland ducts through the mouth. If effective, this stops saliva getting from these 4 glands into the mouth, causing the glands to shrink which significantly decreases drooling. Other smaller salivary glands in the mouth will continue to produce saliva so your child's mouth will not become overly dry.


For information on how to care for your child after the surgery, please see the following handout: Salivary Duct Ligation Handout


The septum is the wall of bone and cartilage between the nostrils. If the septum is bent or causes a blockage, your child can have trouble breathing.

During a septoplasty (also called septal surgery), a doctor straightens your child's septum.


More resources:


Saliva comes from salivary duct glands. These glands can become inflamed when the glands are too narrow. They can also become inflamed when debris or stones block the gland openings.


A sialendoscopy is a procedure where a doctor examines the openings of your child's salivary glands, using a small camera. During the procedure, the doctor will also remove any stones or debris blocking the glands.

When a baby develops inside the uterus, different parts of the body form and grow into place. The thyroid gland forms behind the tongue and then moves along a channel (called a duct) into its position over the trachea (windpipe). The duct disappears as part of the normal development. Sometimes, this duct, called the thyroglossal duct, remains. Surgery may be suggested because infections can occur, or if the cyst presses on throat passages making it hard to breathe or swallow.

The thyroid is a butterfly-shaped organ at the front of the neck. It produces hormones that affect metabolism, body temperature, heart function, mood, and other body systems.


A thyroidectomy is surgery where a doctor removes your child's thyroid. Your child may need this surgery because of thyroid nodules, autoimmune disease, thyroid cancer, or another reason. 


Learn more:


A tongue tie is when the tissue that connects the bottom of the tongue to the floor of the mouth (frenulum) is too short and tight causing the movement of the tongue to be restricted. A tongue tie release surgery, also known as a frenotomy, is a procedure done to release the tissue that attaches the tongue to the floor of the mouth. This is most commonly done when it is affecting feeding or speech.


For information on how to care for your child after the surgery, please see the following handout: Tongue Tie Release Handout

The tonsils and adenoids are small masses of spongy tissue. The tonsils are in the back of the throat on both sides of the tongue. The adenoids are at the back of the nose where the passages of the nose and throat meet. The doctor may recommend a tonsillectomy with or without an adenoidectomy if they feel that your child is having a lot of infections, or they have large tonsils or adenoids that make breathing difficult.

The trachea, also called a windpipe, is part of the airway. It helps to move air into the lungs.


A tracheostomy is a surgery where a doctor puts a tube in your child's trachea. Your child may need this surgery to help with breathing, or another reason.


Learn more:


The mastoid bone is a part of the skull and lies behind the ear lobe. Sometimes, the cells of the mastoid bone, and/or the small bones (ossicles) inside the ear, are destroyed by chronic infection or a growth known as a cholesteatoma. When this happens, the affected mastoid cells may need to be removed which is known as a mastoidectomy.
