Trans-sellar-trans-sphenoidal encephalocele presenting as nasal obstruction in an infant: a case report and systematic review of existing reports.

Trans-sellar trans-sphenoidal encephalocele is a rare congenital anomaly, with only around 20 cases having been documented in literature around the world. Surgical repair of these defects in the pediatric population commonly uses either the transcranial or the transpalatal approach, with the choice of approach being individualized based on the clinical features, age, and associated defects present in the patient. Here, we document a case of a 4-month-old child who presented to us with nasal obstruction, who was diagnosed with this rare entity and successfully underwent a transcranial repair for the same. We also provide a systematic review of all existing case reports that have described this rare condition in the pediatric population, as weel as the different surgical approaches used in each case.
