Lesions affecting the anterior skull base represent a rare group of craniofacial pathologies. A tumor of the facial midline, meningitis, or rhinoliquorrhea may be indicative of malformations like dermoid cysts, gliomas, encephaloceles, or nasal fistulas.


We present a case series of 13 children (4 months to 12 years; 8 males, 5 females) with lesions involving the anterior skull base, which were treated surgically in an interdisciplinary setting. This case series includes cases of nasal fistulae (n = 5), nasal cysts (n = 5), aneurysmal bone cyst, nasal glioma, and meningoencephalocele (n = 1).


All lesions were resected with a transnasal, transcutaneous, and/or transcranial approach with reconstruction of the anterior skull base if intracranial/intradural extension was detected. In 5 cases, a dura leakage was visible, which was sealed via Onlay-technique in 3 cases, whereas in 2 cases involving a greater dural defect, the GAP-CAS technique was performed. No complications occurred, and no recurrence was visible in a long-term follow-up. An algorithm for a systematic approach to these various pathologies is provided.


Congenital pathologies of the anterior skull base are rare, challenging to diagnose, and present as clinical emergencies. An interdisciplinary surgical approach is needed for best functional and aesthetic results.
