Congenital absence of the nasal septum in a Nigerian newborn with multiple congenital anomalies.

Congenital absence of the nasal septum (hyporhynia) is infrequently reported in the literature. We report a rare case in a newborn with multiple congenital anomalies with the aim to highlight its rarity and compatibility with life in a resource-limited setting. The case notes of the child were summarised and the relevant literature reviewed to give the report a context. A 2-hour-old term baby boy presented with a history of abnormal facie characterised by a single nostril and noisy breathing. On examination, he had stridulous breathing, bilateral proptosis, sloping of the forehead, depressed nasal bridge absent nasal septum, absence of columella and hypoplastic mid-face, among other dysmorphic features. A diagnosis of hyporhynia in a baby with multiple congenital anomalies was made and managed accordingly. The baby was discharged to continue follow-up. Congenital absence of the nasal septum is rare and could present without respiratory distress and may be compatible with life. © BMJ Publishing Group Limited 2020. No commercial re-use.
