Airway-Aware Orthodontic Assessment
Airway-Aware Orthodontic Assessment in Auckland
Some patients who come to Parnell Orthodontics for a straightforward bite or crowding assessment also have concerns about mouth breathing, snoring, disrupted sleep, or have been told by their GP or ENT that they may have airway-related issues. These are not unrelated — the size, shape, and position of the jaws have a direct bearing on the dimensions of the upper airway, and orthodontic or orthopedic treatment that changes jaw position or palatal width can affect airway anatomy in meaningful ways. This does not mean orthodontics treats sleep disorders. It means that patients with airway concerns and a concurrent bite or skeletal problem deserve an assessment that considers both.
At Parnell Orthodontics, Dr Adith provides airway-aware orthodontic assessments for patients where mouth breathing, snoring, or sleep concerns coexist with a dental or skeletal discrepancy. The scope of this assessment is clearly defined: it identifies the orthodontic and skeletal factors that may be contributing to or exacerbating an airway concern, recommends appropriate orthodontic treatment where indicated, and ensures that patients who require investigation or management of obstructive sleep apnoea or other sleep-disordered breathing conditions are referred appropriately to the right medical specialist.
An Important Clinical Note
Orthodontics does not diagnose obstructive sleep apnoea. Orthodontics does not independently promise to cure snoring or sleep-disordered breathing. Any clinical or marketing claim that orthodontic treatment guarantees an improvement in sleep quality or OSA severity is not supported by the evidence and should be approached with caution. Dr Adith's airway-aware assessment is grounded in what the published evidence supports — which is that certain skeletal and dental conditions are associated with increased airway compromise, that correcting them as part of a broader treatment plan may produce airway benefits, and that the appropriate investigation and management of sleep disorders belongs with qualified sleep physicians and respiratory specialists. Patients seeking investigation or treatment for obstructive sleep apnoea are referred to the appropriate medical pathway alongside, not instead of, any indicated orthodontic care.
Who Is This Assessment For?
This assessment is appropriate for patients who have one or more of the following alongside a bite or jaw concern: habitual mouth breathing, chronic nasal obstruction, a history of snoring reported by a family member or partner, daytime fatigue that may relate to disrupted sleep, a previous diagnosis of obstructive sleep apnoea for which no oral appliance or orthodontic consultation has been undertaken, or parents of children whose dentist or GP has raised concerns about mouth breathing, tongue posture, or disturbed sleep patterns.
It is not a sleep study, and it does not replace a medical evaluation. It is a specialist orthodontic consultation that takes airway anatomy into account rather than ignoring it.
What the Assessment Covers
Dr Adith examines the skeletal and dental factors that have a known relationship with upper airway dimensions — palatal width, vertical jaw relationships, mandibular position and size, tongue posture, and nasal airway space where visible on CBCT imaging when this is already being undertaken for orthodontic purposes. These findings are interpreted in the context of the patient's reported symptoms and any existing medical investigations.
Where a narrow upper jaw exists alongside airway concerns, palatal expansion — including MARPE in older patients — may be discussed as a treatment option that addresses both the dental and the airway anatomy. The evidence for palatal expansion improving nasal airway dimensions is reasonably well-established, particularly in growing patients. Where mandibular retrognathia — a posteriorly positioned lower jaw — is a contributing skeletal factor, the orthodontic and potentially surgical options for correcting this are discussed alongside their potential airway implications.
Where the assessment findings suggest that sleep-disordered breathing warrants formal investigation, Dr Adith will recommend referral to a sleep physician or respiratory specialist and can assist with coordinating this alongside the orthodontic treatment plan.
For Children and Adolescents
Mouth breathing in children deserves early attention. Chronic mouth breathing is associated with specific patterns of facial growth — a longer, narrower face, a high arched palate, and a posteriorly rotated mandible — that can worsen both the airway and the bite over time. Identifying these patterns early, addressing any dental or skeletal factors that can be managed orthodontically, and referring to an ENT or sleep specialist where appropriate gives children the best chance of both a functional airway and a well-developed bite. Parents who have noticed their child sleeping with their mouth open, snoring, or breathing loudly are encouraged to raise this at the initial consultation.
Collaboration With Other Specialists
Managing patients with airway concerns well requires communication between specialists. Dr Adith works collaboratively with GPs, ENTs, sleep physicians, myofunctional therapists, and oral and maxillofacial surgeons to ensure that patients with overlapping airway and orthodontic needs receive coordinated, evidence-based care rather than conflicting advice from isolated practitioners. Where other specialist input has already been obtained, Dr Adith will review the relevant reports and integrate those findings into the orthodontic assessment.
