Traumatic, spontaneous and postoperative CSF rhinorrhea.

F Loew, B Pertuiset, E E Chaumier

    Advances and Technical Standards in Neurosurgery

    Summary

    Cerebrospinal fluid (CSF) fistulas, often causing meningitis, can result from head injury or other conditions. Surgical repair offers satisfactory outcomes, with low recurrence and mortality rates, preventing potentially fatal meningitis.

    Area of Science:

    • Neurosurgery
    • Otolaryngology
    • Neurology

    Background:

    • Cerebrospinal fluid (CSF) fistulas are a significant complication following head trauma, but also arise spontaneously or secondary to tumors, empty sella syndrome, encephaloceles, intracranial hypertension, or post-surgical procedures.
    • The primary risk associated with CSF fistulas is the development of meningitis, which can be the initial clinical presentation.
    • CSF leakage from the nose is the most common symptom, though meningitis may present first.

    Purpose of the Study:

    • To review the causes, diagnostic methods, and surgical treatments for cerebrospinal fluid (CSF) fistulas.
    • To evaluate the efficacy and outcomes of surgical interventions for various types of CSF fistulas.
    • To discuss management strategies for both traumatic and non-traumatic CSF fistulas based on extensive clinical experience.

    Main Methods:

    • Isotope cisternography and metrizamide CT cisternography are key diagnostic tools for localizing CSF fistulas.
    • Surgical approaches include transfrontal repair with pericranial flaps or fascia lata grafts for frontal/ethmoidal fistulas.
    • Packing the sphenoidal sinus with muscle is the preferred method for sphenoidal fistulas.

    Main Results:

    • Operative treatment yields satisfactory results for CSF fistulas.
    • Recurrence rates are approximately 6% but are typically manageable with reoperation.
    • Mortality rates range from 1-3%, considered acceptable given the prevention of potentially fatal meningitis.

    Conclusions:

    • Surgical intervention is effective in treating CSF fistulas and preventing meningitis.
    • While recurrences can occur, reoperation is generally successful.
    • Ongoing efforts are needed to refine surgical techniques, particularly to minimize the risk of anosmia.
