Key Points to Remember
- Jaw deformities occur when one or both jaws grow too much or too little.
- Children with these conditions may have trouble speaking and chewing, and they sometimes develop long-term problems with the teeth and gums.
- The most effective treatment approach for jaw deformities is often a combination of surgery and braces or other orthodontic appliances.
What are the most common types of jaw deformities?
Jaw deformities are a common condition, ranging from mild abnormalities to more severe defects that can be surgically corrected. In some instances, the upper or lower jaw — or both — may grow too little or too much, resulting in malocclusion, the improper alignment of the teeth in relation to the first molars.
What causes a child to have a short lower jaw?
A child with micrognathia has a lower jaw that’s much shorter or smaller than the rest of their face. Children may be born with this problem, or it can develop later in life. It mainly occurs in children who are born with certain genetic conditions, such as trisomy 13 and progeria. It can also be the result of fetal alcohol syndrome.
What is jaw distraction surgery for breathing problems?
Jaw distraction surgery (mandibular distraction) A small or recessed jaw can cause severe or ongoing breathing difficulties. Jaw distraction involves the surgical insertion of distraction (lengthening) devices into the jaw. These devices lengthen the jaw bone, which allows the airway to open up and the child to breathe clearly.
Why does my child have a bump on his jaw?
Children may be born with this problem, or it can develop later in life. It mainly occurs in children who are born with certain genetic conditions, such as trisomy 13 and progeria.

Besides growth differences between your upper and lower jaws, jaw deformities may be caused by genetic factors, trauma and certain birth defects, such as cleft lip and cleft palate.
What causes uneven jaw growth?
Summary. Uneven jaw occurs when the upper jaw, or maxilla, does not properly line up with the lower jaw, or mandible. This arises due to a range of factors, including misalignment of the teeth, disorders of the temporomandibular joint (TMJ) connecting these bones, trauma, as well as birth defects.
Can I fix an uneven jaw without surgery?
TMJ issues can cause facial asymmetry with or without pain. Most often these issues for uneven jaws can be treated non-surgically. However, many orthodontist and Oral Surgeons may tell you the only way to fix this is to do orthognathic surgery.
Can jaw alignment be done without surgery?
Braces and clear aligners can fix an underbite. There are several non-surgical options for fixing an underbite. “For mild cases, a dentist may recommend metal braces or clear aligners to move teeth into the correct position. In some cases, a dentist may use a grinding device to shave down larger teeth,” Ataii says.

What is the procedure to fix a child's jaw?
This surgery, called orthognathic surgery, creates a cut or osteotomy in the affected jaw, and the bones are repositioned so that they align better. Generally, the bones are held in their new positions with plates, screws and wires. The child may also need arch bars, a type of temporary braces, placed on the teeth to hold the jaws together and add stability (a procedure called fixation). This procedure realigns the upper and lower jaws so that, when they are brought together, the child's bite is aligned.
What type of surgery is used to correct jaw deformities?
Another kind of surgery that can be done to correct jaw deformities is bone positioning by distraction ( separating). This surgery was originally developed for lengthening uneven limbs, but it has now been adapted to meet the needs of children with congenital or acquired skull and jaw deformities.

The causes of tooth-maxillofacial deformations are very diverse. Thus, the organo- and morphogenesis of the jaws in the fetus may be affected by the hereditary effect on the embryo, the parents borne diseases (including endocrine and metabolic disorders in the mother's body, infectious diseases ), radioactive irradiation, and also due to physiological and anatomical disorders of the genital organs of the mother and the wrong position of the fetus.
What are the causes of jaw growth?
In early childhood, the development of the jaws can be affected by endogenous factors (heredity, endocrine disorders, various infectious diseases, metabolic disorders) and exogenous effects (inflammation in the areas of jaw growth, trauma, including birth, radiation damage, mechanical pressure, harmful habits - sucking a finger, pacifiers, lower lip or putting a cam under the cheek during sleep, pushing the lower jaw forward during the eruption of wisdom teeth, while playing the children's violin and t etc., dysfunction of the masticatory apparatus, violation of the act of swallowing, nasal breathing, etc.).
What is the pathogenesis of the combined deformities of the bones of the face?
The pathogenesis of the combined deformities of the bones of the face is closely related to the impairment of the function of the synchondrosis of the base of the skull. Micro- and macrognathia are caused either by oppression or irritation of the growth zones, localized in the heads of the mandibular bone.

What is a congenital ear deformity?
The ear is made up of three main sections—the outer, middle, and inner ear. The outer ear represents the external, visible ear—called the auricle or pinna—and the external auditory canal. It is more complex than you might guess, containing many structures, curves, and folds—all of which work in concert to collect sound waves and direct them to the middle and inner ear, which work together with the brain to allow us to hear sound.
What are the types of outer ear congenital deformities?

How are congenital ear deformities diagnosed?
Congenital deformities of the outer ear are typically diagnosed at birth during a physical exam. Your doctor will closely examine your baby to assess symmetry and proportionality, as well as to check for facial and jaw defects. They will also look into the ears using an otoscope, a device that allows for the visual examination of ear canal and tympanic membrane, or ear drum.
What causes ear deformities?
Because outer ear deformities are present from birth, a number of factors may contribute to their development: 1 Environment. Congenital ear deformities can occur when a developing baby is exposed to certain conditions in the uterus. Prenatal exposure to particular drugs, including isotretinoin (Accutane, for example), thalidomide, mycophenolate, and alcohol have been linked to the development of outer ear deformities. 2 Fetus positioning. In some cases, deformities arise due to how a baby is positioned in the uterus or during birth. For instance, a reduction in blood supply to the outer ear can lead to abnormal development.
How common are congenital deformities of the outer ear?
Congenital deformities of the outer ear—that is, deformities of the visible ear and ear canal that are present from birth—are common.

Why are premature babies more vulnerable to positional head deformities?
Premature babies are more vulnerable to positional head deformities because their skulls are softer than those of full-term babies and because their medical needs sometimes result in spending a great deal of time on their backs without being moved or picked up.
How to diagnose positional plagiocephaly?
A child’s physician usually makes a diagnosis of positional plagiocephaly simply by examining the child's head. The doctor will also note whether regular repositioning of your child's head during sleep successfully reshapes the growing skull over time. X-rays or a CT scan of may be necessary to confirm diagnosis or clarify if the skull bones are normally separated or if they fused together too soon. If the bones aren't fused, the doctor will rule out craniosynostosis and confirm that the child has positional head deformity.
Why is my baby's head flat?
Because infants' heads are soft to allow for the incredible brain growth that occurs in the first year of life, they're susceptible to being "molded" into a flat shape.
