Abstract
Background: Spontaneous descent of the CSF (Cerebrospinal fluid) from the nose is called rhinorrhea. The causes are defects in bones of the base or meningeal tear. The surgical management is still a challenge. The surgical repair is a must to prevent the complication which could be brain abscess, meningitis, or pneumocephalus. The available surgical management is either transnasal, or transcranial. The endonasal route represents an easy access but equally aggressive alternative and of limited access. Objective: We reviewed the clinical outcomes of thirteen cases of spontaneous CSF leakage managed by transcranial intradural approach. Patients and Methods: This is a retrospective study about the records of 13 patients who underwent transcranial intradural approach as a surgical management for spontaneous CSF rhinorrhea in our department in the period between November 2017 and October 2019. Results: CSF leakage stopped after initial surgery in 12 of 13 patients, giving a success rate of 92.3%. The remaining case did not agree for new surgery and the case resolved without surgery for this patient. Postoperative complications included superficial wound infection in one patient, and anosmia in one patient. No other neurological problems were encountered over the ten-months’ follow-up period. Conclusion: The transcranial route is the treatment of choice for patients with anterior cranial fossa spontaneous CSF rhinorrhea. A satisfactory surgical outcome depends on exact diagnosis, proper operative approach, and the surgeon’s skills and experience.

Spontaneous rhinorrhea is usually due to a defect in the skull base and this condition may lead to serious complications, such as brain infections or pneumocephalus [1] [2] [3]
Summary
CSF leakage from the anterior skull base is a common problem that faces most neurosurgeons in their daily practice.
