Postnatal outcomes and risk factor analysis for sixty-two patients with prenatally diagnosed oropharyngeal masses
2021
Abstract Objectives To describe our experience treating prenatally diagnosed oropharyngeal masses in a novel, multidisciplinary collaboration. To identifying outcomes and risk factors associated with adverse postnatal outcomes. Methods This is a sixty-two patient case series at an academic referral center. Patients with prenatally diagnosed oropharyngeal masses were identified through a programmatic database and confirmed in the electronic health record. Results Sixty-two patient with prenatally diagnosed oropharyngeal mass were identified, with prenatal imaging at our institution confirming this diagnosis in fifty-seven patients, short term outcomes analysis conducted on forty-four patients, and long-term outcomes analysis conducted on seventeen patients. The most common pathology was lymphatic malformations (n = 27, 47.4%), followed by teratomas (n = 22, 38.6%). The median mass volume from all available patient imaging (n = 57) was 60.54 cm3 (range 1.73–742.5 cm3). Thirteen pregnancies were interrupted, six infants expired, and thirteen cases had an unknown fetal outcome. Confirmed mortality was 6/57 patients with imaging-confirmed oropharyngeal masses (10.5%). Fourteen (56%) of the surviving patients (n = 25) were delivered by Ex Utero Intrapartum Treatment (EXIT) procedure and the median NICU stay was thirty-six days (range: 3–215 days). There was no association between airway compression/deviation/displacement, stomach size, polyhydramnios, or mass size and mortality. Seventeen patients had more than one year of follow-up (mean 5.3 ± 2.4 years). These seventeen patients underwent general anesthesia a total of ninety-two times (mean 5.4 ± 4.3) and had a total of twenty-three mass-related surgeries. The great majority of patients required an artificial airway at birth, feeding support, and speech/swallow therapy. Conclusions Oropharyngeal mass involvement of key anatomic structures—the neck, upper thorax, orbit, and ear, has a greater association with mortality than mass size. Regardless of the size and involved structures, oropharyngeal masses are associated with a high burden of intensive medical care and surgical care beginning at or before birth.
