What is it?

A look at whether rapid palatal expansion (RPE) treatment can improve air flow in pediatric patients鈥� nasal airways.

What problem does it aim to solve?

Nasal blockage is a common problem which can disrupt normal breathing and cause obstructive sleep apnea. Currently the main treatments involve surgery, which is generally not recommended until after the teen growth spurt is complete. Other treatment options could provide some relief earlier.

How does it work?

RPE treats upper-jaw constriction in growing patients. Although it mainly targets the mid-palate area, it impacts the airway width as well. Patients were measured before and after treatment, and also were scored using 鈥淣asal Obstruction Symptom Evaluation鈥�, or NOSE. The results: 鈥淭he amount of expansion significantly correlated with changes in the NOSE score.鈥�

What are the real-world implications?

鈥淭his may show the possibility of considering RPE in managing resistant pediatric nasal airways.鈥�

What are the next steps?

Future studies should look at long-term impact and involve multidisciplinary teams.
