Novel use of high-flow nasal cannula therapy in the management of pyriform aperture stenosis: case report

“…It often presents in the first hours of life with laboured breathing, respiratory distress, stertor, and cyclical cyanosis that improves with crying. 1,3…”

“…A lack of data on the natural course of pyriform aperture stenosis makes it difficult for clinicians to predict which patients will not improve with conservative management alone. 3…”

“…5 However, subsequent studies found no correlation between degree of stenosis and requirement for surgery, instead suggesting evaluation of the patient's symptoms and progress. 3,9 Indications for surgery within these studies were: failure of response to medical treatment, presence of sleep apnoea due to nasal airway obstruction, an inability to insert a 6 French gauge feeding tube, extubation failure, and frequent feeding difficulties with cyanosis. Recently, Moreddu et al .…”

“…1,2 Symptoms include laboured breathing, apnoeic events, cyclical cyanosis improved by crying, and failure to thrive. 1,3…”

Modeling congenital nasal pyriform aperture stenosis using computational fluid dynamics

“…This variability complicates treatment approach to CNPAS. Milder cases respond to conservative treatment, as the stenosis improves with age [3, 4]. Conservative measures include nasal humidifiers, nasal decongestants, treatment of reflux, and an oral airway [4, 5].…”
