Management remains difficult. There is no specific treatment protocol. Traditional surgery would be anachronistic; a non-invasive or minimally invasive therapeutic option is required. However, the rarity of the disease and the infantile context render randomised clinical trials difficult.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>We present the case of a one-month-old Caucasian boy with CNPAS. He presented to the Emergency Department of the Bambino Ges\u00f9 Pediatric Hospital with nasal obstruction, noisy breathing, feeding difficulties, and suspected sleep apnoea. During hospitalisation, he underwent overnight pulse oximetry, airway endoscopy, and maxillofacial computed tomography (CT); the final diagnosis was CNPAS with moderate obstructive sleep apnoea syndrome. We successfully treated the patient using an innovative strategy that involved collaboration between ear-nose-and-throat surgeons and orthodontists.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>A combination of minimally invasive balloon surgery and placement of a palatal device may successfully treat CNPAS; it may also treat other types of nasal bone stenosis.
