Management of the congenital midline nasal mass: A review

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.

Schneiderian Papillomas and Nonsalivary Glandular Neoplasms of the Head and Neck

“…They may be composed entirely of epithelial or mesenchymal elements or of both and should be distinguished from teratomas and dermoids (77)(78)(79)(80)(81)(82)(83)(84).…”

Extranasal nasal glioma

“…1 The differential Eye diagnosis includes dermoid/epidermoid cysts, encephalocoeles, and nasal gliomas. Nasal gliomas are thought to be collections of heterotopic tissue of neurogenic origin, which have lost their intracranial connection and may represent variants of encephalocoeles, 2 with approximately 20% retaining intracranial connectivity.…”

Endoscopy in the Evaluation and Management of the Pediatric Airway

“…Dermoid sinus (with/without intracranial extension), encephaloceles, and gliomas are the most common midline nasal masses (Hughes, 1980), and imaging must be performed prior to any surgical intervention. If intracranial extension is not known, there is risk of CSF leak, meningitis, or intracranial injury (Hedlund, 2006).…”
