Pediatric Airway Assessment: Catching Breathing Problems Before They Shape the Face

Airway screening begins at the first dental visit (age one) and continues at every subsequent examination. Formal assessment with CBCT imaging is typically indicated between ages five and eight when clinical signs of mouth breathing, narrow palate, or sleep-disordered breathing are identified — this timing coincides with the interceptive orthodontic window.

Chronic mouth breathing, snoring, restless sleep, bedwetting beyond age five, dark circles under the eyes, crowded teeth, narrow face, difficulty paying attention in school, hyperactivity, frequent upper respiratory infections, and difficulty with nasal breathing. Many of these signs are attributed to other causes when the underlying issue is airway obstruction.

Yes. The roof of the mouth is the floor of the nose. A narrow palate directly constricts the nasal floor, increasing nasal airway resistance and forcing mouth breathing. Palatal expansion widens both the dental arch and the nasal floor, improving nasal airflow. This is one of the most impactful interventions in pediatric airway management.

Decades of research confirm that chronic mouth breathing during craniofacial development produces measurable skeletal changes: narrow maxilla, elongated lower face, retrognathic mandible, increased anterior face height, and lip incompetence. These changes become increasingly difficult to correct once growth slows. Early intervention during active growth can redirect the developmental trajectory.

Pediatric sleep-disordered breathing fragments sleep and eliminates restorative sleep stages, producing daytime symptoms that mimic ADHD: inattention, hyperactivity, emotional dysregulation, and poor academic performance. Studies demonstrate that treating the underlying airway obstruction (adenotonsillectomy, palatal expansion) resolves these behavioral symptoms in a significant percentage of children initially diagnosed with ADHD.

Rapid palatal expansion separates the midpalatal suture, widening both the dental arch and the nasal floor. The increased nasal floor width reduces nasal airway resistance by 25 to 40 percent, facilitating nasal breathing. Children who could not breathe through their nose before expansion often can afterward — a functional change with profound implications for sleep quality and craniofacial growth.

Both, ideally. The ENT evaluates the nasal and adenoid components. The dentist evaluates the maxillary width, mandibular position, tongue mobility, and dental components. At ADSC, the dental airway assessment identifies which factors require dental/orthodontic intervention and which warrant ENT referral. Coordinated care between both specialists produces the best outcomes.

A restrictive lingual frenulum prevents the tongue from resting in its normal improved position against the palate. This removes the transverse force that stimulates palatal expansion during growth, contributes to narrow palatal development, and positions the tongue posteriorly where it can partially obstruct the oropharyngeal airway. Frenectomy combined with myofunctional therapy restores tongue function and position.

Myofunctional therapy consists of exercises that retrain the muscles of the tongue, lips, and cheeks to establish correct resting posture (tongue improved, lips sealed, nasal breathing). Proper orofacial muscle function supports palatal development, nasal breathing, and swallowing patterns. It complements orthodontic and surgical interventions for airway improvement and is performed by trained myofunctional therapists.

ADSC does not perform sleep studies directly but coordinates referrals to pediatric sleep medicine physicians who conduct diagnostic testing. The clinical airway assessment and screening questionnaires at ADSC identify children who warrant formal sleep evaluation and facilitate the referral process.

Airway screening is integrated into the standard pediatric dental examination at no additional cost. If CBCT imaging is clinically indicated, the imaging fee applies. Dental insurance typically covers the examination and radiographs as diagnostic services. Any recommended treatment (palatal expansion, referral for adenotonsillectomy) is costed separately based on the specific intervention.

Yes. The craniofacial growth changes caused by chronic childhood mouth breathing — narrow palate, retrognathic mandible, increased lower facial height — create the anatomical substrate for adult obstructive sleep apnea. Treating the airway during growth can prevent the skeletal pattern that would otherwise predispose to lifelong sleep-disordered breathing.

CBCT provides a three-dimensional volumetric measurement of the airway from the nasal cavity through the oropharynx, identifying the specific location and degree of constriction. It also reveals adenoid size, palatal arch dimensions, and mandibular position — data that guides treatment decisions. CBCT is used selectively when clinical findings suggest airway compromise that requires quantification.

Some children do improve as tonsils and adenoids naturally involute during adolescence. However, the craniofacial growth changes caused by years of mouth breathing and sleep-disordered breathing do not self-correct. Waiting for the child to "grow out of it" risks permanent facial skeletal changes and years of disrupted sleep during critical developmental windows. Early assessment identifies which children need intervention now.

Combined treatment is common and addresses different levels of the airway: adenoidectomy clears the nasopharyngeal obstruction, and palatal expansion widens the nasal floor and maxillary arch. The sequence (which procedure first) is coordinated between the ENT surgeon and the dental team. Combined intervention produces synergistic improvement in airway patency and craniofacial growth.
