ABSTRACT
The nasal encephalocele, the glioma, and the dermoid are the most common of the congenital midline nasal masses. Due to similar embryologic development, each of these lesions may be associated with bony cranial defects and intracranial abnormalities, as well as CSF leakage and the potential for fatal meningitis if not handled properly. Properative manipulation should be avoided. Radiologic studies are instructive only if they are positive. If intracranial attachments are identified radiologically or suspected clinically, neurosurgical consultation should be obtained, and intracranial exploration and resection should be carried out as the initial procedure. Extra-cranial resection of the remaining mass may be performed immediately after intracranial resection, may be postponed, or may become unnecessary.
