Objective: To discuss the diagnosis of child meningoencephaloceles in nasal cavity and its methods of transnasal endoscopic surgery.
Method: Two cases of congenital meningoencephalocele which have manifested mass in nasal cavity or nasopharynx received total resection by transnasal endoscopic surgery. Their medical records, radiographic imagings, and surgical procedures were reviewed.
Result: We identified 2 patients with endonasal meningoencephaloceles whose main symptoms were watery rhinorrhea,nasal obstruction and mass in nasal cavity. A high index of suspicion for this diagnosis must be maintained, especially in patients with reiterative high fever or meningitis. Imaging examination should be done in those patients. Endonasal meningoencephaloceles, wherever the bone defects were located on the ethmoid roof or skull base,can be remove by endoscopy.
Conclusion: CT and MRI are significant in diagnosis of endonasal meningoencephaloceles, nasal endoscopic surgery could be considered to be the best surgical approach without any severe complications.
