Congenital nasal obstruction in infants: A retrospective study and literature review

Objectives: To identify etiologies of congenital nasal obstruction and describe clinical practice patterns in the evaluation, diagnosis, and treatment of symptomatic infants.

Methods: An electronic chart review from 1/1/2006-10/1/2016 for all patients with a diagnosis of nasal obstruction within the first six months of life using ICD-9 and 10 codes 478.19 and J34.89.

Results: A total of 34 patients were evaluated by the Division of Otolaryngology for this chief complaint. 38% of neonates were born premature and 32% were admitted to the NICU at birth, with a female-to-male ratio of 1:1.4. Presenting signs and symptoms included: stertor (44%), cyanosis (24%), stridor (24%), retractions (21%), rhinorrhea (21%), apnea (12%), and epistaxis (8%). 47% of patients received ancillary radiographic imaging (CT or MRI). Diagnoses observed include: midnasal stenosis (38%), pyriform aperture stenosis (21%), choanal stenosis (12%), dacryocystocele (6%), microrhinia (6%), septal deviation (6%), nasopharyngeal reflux (3%), nasopharyngeal teratoma (3%), neonatal rhinitis (3%), and pharyngeal wall collapse (3%). 71% of patients were noted to have bilateral nasal obstruction. 41% of infants were found to have an associated ear, nose, and throat anomaly. 15% of patients required surgical intervention. The mean time-to-resolution was 240 days.

Conclusion: Congenital nasal obstruction has a broad differential diagnosis: the timing, onset, and laterality of symptoms can provide insights into the source of upper airway compromise. Most infants improve through conservative management (i.e. suctioning, humidification) and medical therapies (i.e. intranasal drops, nasal sprays).
