“…The inability to pass a 5F catheter and a radiographically measured pyriform opening < 8–10 mm in a full-term infant are considered diagnostic. If holoprosencephaly is suspected by the presence of a central maxillary incisor, encephalic CT or magnetic resonance imaging should also be performed [6-8]. Once the diagnosis has been confirmed, the treatment approach must take into account the severity of the clinical condition, any associated comorbidities, and the neonate’s global prognosis.…”

BackgroundCongenital nasal pyriform aperture stenosis is a rare and potentially lethal form of airway obstruction in newborns. Immediate recognition and appropriate therapy are mandatory for this potentially life-threating condition. This anomaly may present as an isolated malformation or may be associated with other cranial-facial anomalies. Clinically, CNPS shows unspecific symptoms of nasal airway obstruction such as apnoic crisis, episodic cyanosis and inability to nurse. The purpose of this report is to present author's experience in the surgical management of this rare pathology in 3 patients.Patients and MethodsThree cases of congenital nasal pyriform aperture stenosis were reviewed for presentation of the disorder, management and effectiveness of the surgical treatment.ResultsAll the patients underwent a surgical correction of the pyriform aperture stenosis using a sublabial approach followed by nasal stenting. During the follow-up no cases of restenosis, respiratory failure or cyanosis were detected.ConclusionsCongenital pyriform aperture stenosis should be suspected in newborns with clinical signs of severe nasal obstruction associated with a difficulty to pass a small catheter though the anterior nasal valve. Timely recognition is mandatory to prevent a potential deadly outcome. Surgical correction of the stenosis though a sublabial approach followed by a nasal stenting revealed to be most effective treatment for these patients.

“…A transnasal approach has also been described, but in our opinion, it is not advisable in neonates because of the reduced dimensions of anatomic structures, which increase the risk of soft-tissue trauma [8]. …”
