Airway-Focused Orthodontic Treatment for Adolescents

The relationship between the developing jaws and the upper airway is an important but often overlooked dimension of adolescent orthodontic care. The size, shape, and position of the jaws directly influences the volume and function of the nasal and pharyngeal airway — and problems with breathing, nasal obstruction, and sleep quality during adolescence can have wide-ranging consequences for growth, development, concentration, and overall health.

At Lusk Orthodontics, airway considerations are integrated into every adolescent orthodontic assessment. Where there is evidence of nasal obstruction, habitual mouth breathing, disturbed sleep, or a skeletal pattern that may be contributing to airway compromise, treatment is planned with these factors explicitly in mind — and, where needed, in close collaboration with ENT consultants and sleep physicians.

Why the Airway Matters in Adolescent Orthodontic Care

Orthodontic treatment has traditionally focused on the alignment of teeth and the correction of the bite. Airway-focused orthodontics takes a broader view — recognising that the position of the jaws, the width of the palate, and the posture of the tongue and lower jaw all influence breathing function, particularly during sleep.

In adolescents, this matters for several reasons:

Mouth breathing and its effects. Habitual mouth breathing — often driven by nasal obstruction from a narrow palate, deviated septum, or enlarged adenoids and tonsils — affects the way the jaws develop. The tongue rests low rather than against the palate, removing one of the key functional stimuli for upper jaw development. Over time, this can lead to a narrower, higher-arched palate, increased facial height, and a pattern of jaw growth that compounds the breathing problem. Identifying and addressing the airway component of an adolescent’s orthodontic presentation can interrupt this cycle at a critical time.

Sleep-disordered breathing. Obstructive sleep apnoea and upper airway resistance syndrome are not conditions exclusive to adults — they occur in adolescents too, and the consequences for neurocognitive development, behaviour, school performance, and long-term cardiovascular health are well established. Where a narrow palate, retrognathic jaw, or vertical skeletal pattern is contributing to disturbed sleep in a teenager, orthodontic intervention can make a meaningful and lasting difference.

The growth window. Skeletal problems that contribute to airway dysfunction can be addressed more readily — and often non-surgically — during adolescence than at any other time of life. Acting within the growth window offers opportunities that are not available once development is complete.

How Airway-Focused Treatment Works at Lusk Orthodontics

Airway considerations are incorporated into the assessment of every adolescent patient. Where relevant, the following are specifically evaluated:

• Nasal breathing versus mouth breathing pattern
• Palatal width and arch morphology
• Tongue posture and function
• Vertical facial pattern and jaw relationship
• Sleep history — including snoring, restless sleep, daytime tiredness, or difficulty concentrating
• Any previous or current assessment or treatment by ENT or sleep specialists

Where findings suggest an airway or sleep component to the patient’s presentation, this is discussed openly with the patient and their parents. Treatment planning then takes these factors into account — not as a secondary consideration, but as a primary treatment objective.

Orthodontic Interventions with Airway Benefit

Palatal Expansion (MARPE)

Widening the upper jaw using MARPE increases the volume of the nasal airway by expanding the nasal floor. In adolescent patients who are mouth breathers due to nasal constriction caused by a narrow palate, MARPE can restore or significantly improve nasal breathing — with beneficial knock-on effects for facial growth, jaw posture, tongue position, and sleep quality.

Where nasal breathing is a treatment objective, palatal expansion is sequenced appropriately and, where ENT pathology is also contributing (such as a deviated septum or turbinate hypertrophy), the orthodontic and ENT teams work together to address both simultaneously.

Functional Appliances

In adolescents with a retrognathic (set-back) lower jaw, the tongue base and soft palate are positioned closer to the posterior pharyngeal wall — reducing the pharyngeal airway space and increasing the risk of airway collapse during sleep. Functional appliances that advance the lower jaw forward improve the jaw relationship and can increase the pharyngeal airway dimension. Where sleep-disordered breathing is associated with a skeletal class II pattern in an adolescent patient, functional appliance therapy may be planned with the dual objective of correcting the bite and improving the airway.

TAD-Supported Open Bite Correction

Anterior open bites are often associated with low tongue posture, mouth breathing, and increased vertical facial dimensions — all of which are relevant to airway function. TAD-supported correction of an open bite during adolescence can improve tongue posture, encourage nasal breathing, and reduce the vertical skeletal pattern that contributes to a narrowed pharyngeal airway.

Orthognathic Surgery Planning

Where a significant skeletal discrepancy is contributing to airway dysfunction and is beyond the scope of orthodontic correction alone, early identification allows appropriate planning for orthognathic surgical correction once growth is complete. In these cases, the adolescent orthodontic phase is managed with the surgical goal in mind — ensuring the patient is well prepared and that no unnecessary treatment is carried out that would need to be undone before surgery.

Myofunctional Therapy as Part of Airway-Focused Care

In selected adolescent patients, abnormal tongue posture or oral habits — such as a low resting tongue position, a tongue thrust swallowing pattern, or habitual mouth breathing — are identified during the orthodontic assessment. These patterns are often both a consequence of nasal obstruction and a perpetuating factor in its effects: a low-resting tongue provides insufficient stimulus for upper jaw development, contributing to the narrow palate and vertical growth pattern that compounds the breathing problem.

Following palatal expansion — and as part of the broader shift towards nasal breathing — myofunctional therapy can play an important role in retraining the tongue, lip, and facial muscles to adopt a more functional resting position and movement pattern. This not only supports the stability of the expansion achieved but helps to establish breathing and swallowing patterns that reinforce the orthodontic result for the long term.

While myofunctional therapy is not offered at Lusk Orthodontics directly, we work with experienced myofunctional therapists in Ireland and the UK, and coordinate referral and communication as a joined-up part of the adolescent patient’s overall care plan where this is indicated.

Working with ENT and Sleep Medicine Specialists

Lusk Orthodontics works closely with ENT consultants and sleep physicians in the assessment and management of adolescent patients where breathing and sleep are a concern. Where a patient is already under the care of a specialist, relevant information is shared and treatment is coordinated. Where an ENT or sleep referral has not yet been made but clinical findings suggest one is warranted, this is discussed with the family and a referral is facilitated where appropriate.
