To investigate antenatally-determined imaging characteristics associated with invasive airway management at birth in patients with cervical masses, as well as to describe postnatal management and outcomes. A retrospective analysis of 52 patients with antenatally diagnosed neck masses was performed using single-center data from January 2008 to January 2019. Antenatal imaging, method of delivery, management, and outcomes data were abstracted from the medical record and analyzed. Antenatal diagnosis of neck masses in this cohort consisted of 41 lymphatic malformations (78.8%), 6 teratomas (11.5%), 3 hemangiomas (5.8%), 1 hemangioendothelioma (1.9%), and 1 giant foregut duplication cyst (1.9%). Mean gestational age at time of diagnostic imaging was 29 weeks 3 days (range: 19w4d – 37w). Overall, 22 patients (42.3%) required invasive airway management at birth, specifically 18 patients (34.6%) required endotracheal intubation and 4 (7.7%) required tracheostomy. 15 patients (28.8%) underwent ex-utero intrapartum treatment (EXIT) for the purposes of securing an airway. Polyhydramnios, tracheal deviation and compression, and anterior mass location on antenatal imaging were significantly associated with incidence of invasive airway intervention at birth, EXIT procedure, and tracheostomy during the neonatal hospitalization (p < 0.025; Fisher's exact test). Logistic regression analysis demonstrated statistically significant association between increasing antenatally-estimated mass volume and incidence of invasive airway management at birth (p = 0.02). Post-natal cervical mass management involved surgical excision (32.7%), sclerotherapy (50%), and adjuvant therapy with rapamycin (17.3%). Demise in the neonatal period occurred in 4 (7.7%) patients. This series documents the largest single-center experience of airway management in antenatally diagnosed cervical masses. Fetal imaging characteristics may help inform the appropriate method of delivery, airway management strategy at birth, and prenatal counseling.
