ABSTRACT
RESUMEN La fístula de líquido cefalorraquídeo (LCR) corresponde a una comunicación anormal entre el espacio subaracnoideo y la porción neumatizada de la base de cráneo anterior en relación con las cavidades paranasales. Fístulas persistentes requieren reparación quirúrgica por el riesgo de meningitis, abscesos cerebrales y neumoencéfalo asociado. El gold standard es el abordaje extracraneal endoscópico. Uno de los principales inconvenientes es dañar estructuras intracraneanas nobles. La ayuda de tecnologías como la cirugía guiada por imágenes, contribuye a disminuir este problema. A continuación se presentan dos casos clínicos de fístula de líquido cefalorraquídeo en base de cráneo anterior, asociado a meningoencefalocele, intervenidos por cirugía endonasal guiada por imágenes.
ABSTRACT Endoscopic management of anterior skull base meningoencephalocele. The cerebrospinal fluid leak (CSF) is an abnormal communication between the subaracnoid space and the pneumatic portion of the anterior cranial base which is related to the paranasal cavities. The persistent leak requires surgery due to the potential complications such as meningitis, cerebral abscess or pneumoencephalus. Extracranial endoscopic approach is the gold standard procedure. One of the most important risk of the surgery is to damage noble intracranial structures. This situation can be ameliorated by using image guided surgery. We present two cases of CSF in anterior cranial base associated with meningoencephalocele that were treated in our center using nasal image guided endoscopic surgery.

CSF rhinorrhoea poses a significant challenge even to most astute and experienced surgeons in its accurate localization and management. The diagnosis of CSF leak is ascertained on proper history, neurologic and otorhinolaryngologic examination, laboratory tests and endoscopic findings supplanted by appropriate radiologic studies. The exact visualization and atraumatic surgical technique using endoscope provides better lighting with magnified view, even in lateral recesses giving an edge over other techniques, thus enhancing the surgical outcome.
