Sleep-Disordered Breathing in Children: A Screening Guide
Screening questions and clinical signs that warrant referral for further airway evaluation.
Pediatric sleep-disordered breathing hides in plain sight because its daytime face doesn't look like sleepiness. It looks like inattention, irritability, poor growth, and morning battles. Children who don't sleep well get evaluated for behavior long before anyone asks how they breathe at night. Whatever your discipline, if children come through your door, you're positioned to catch this.
History questions worth asking every family
- Does your child snore? How many nights a week?
- Have you ever seen a pause in breathing, a gasp, or a snort during sleep?
- Mouth open or closed during sleep? During the day?
- Restless sleeper? Sweaty? Strange positions, head hanging off the bed?
- Grinding teeth at night?
- Bedwetting beyond the expected age, or a return of it?
- How are mornings? Hard to wake, cranky, headaches?
- How is attention and mood by afternoon?
A "yes" on snoring three or more nights a week, or any witnessed pause, moves the conversation from screening to referral on its own.
What you can observe in the chair
Within your scope, and most of this is observation, not diagnosis:
- Rest posture: lips apart at rest, low tongue position, chin lift
- Facial signs: long lower face, dark infraorbital circles, narrow nostrils
- Oral signs where visible: high narrow palate, posterior crossbite, anterior open bite, dental wear consistent with grinding, scalloped tongue edges
- Tonsils visibly meeting or near the midline when the child opens wide
- Voice and breathing: hyponasal speech, audible breathing at rest, frequent sniffing
Validated caregiver questionnaires for pediatric sleep exist and take minutes; using one gives your referral letter weight.
Where to send them
Polysomnography remains the diagnostic standard for obstructive sleep apnea, so sleep medicine and ENT sit at the center of the pathway. Dentistry and orthodontics matter when the palate and bite are involved. Allergy and airway hygiene matter when congestion is chronic. Myofunctional therapy enters once structure and obstruction are being addressed, not instead of that.
Write down what you saw and heard, in plain terms, and send it with the family. "Snores five nights a week, witnessed gasps, open mouth posture in the chair, tonsils near midline" gets a child seen faster than "possible SDB, please evaluate."
The screening takes five minutes. For the right child, it changes the next decade.
Written for clinicians as an orientation, not a protocol. Screening is not diagnosis, and scope of practice varies by license and state. When in doubt, refer.
