Abstract:
The rare clinical picture of nasal agenesis is to be presented on the basis
of a female newborn. Intrauterine growth restriction with polyhydramnios and midface hypoplasia were noted during pregnancy. Primary cesarean section at
38+4 weeks’ gestation was done. Airway management was achieved by splinting through a Mayo tube which was subsequently replaced by
a pharyngeal endotracheal tube without signs of respiratory failure. In addition to a complete nasal agenesis, hypertelorism, a Gothic palate,
bilateral microphthalmus, and iris coloboma were found. Ultrasound scans of cerebral structures were normal. An orogastric tube was placed, and drinking
training and a special pacifier improved coordination and drinking performance. We suspected a case of Bosma arhinia microphthalmia syndrome
(BAMS). The structural maintenance of chromosomes flexible hinge domain (SMCHD) containing 1 gene plays a key role in the embryogenesis of the human
nose and is known for mutations in BAMS. A heterozygous de novo mutation in the SMCHD1 gene (c.1043A 〉 G; pHis348Arg) was confirmed by molecular
genetic analysis. Initial stabilization after birth is often a challenge in patients with nasal agenesis. They are often intubated immediately
postpartum and electively tracheotomized. In the absence of respiratory problems and appropriate growth, however, there is no urgent indication for
early plastic surgical treatment, given the inherent risks of sepsis and growth disorders in the midface.
