Repair of cerebrospinal fluid fistula following transoral transclival approach to a basilar aneurysm

Technical note

Restricted access

✓ A technique for closure of a cerebrospinal fluid fistula following a transoral transclival approach to a basilar aneurysm is described. Transposition of a rotation flap of the mucosa of the septum and the floor of the posterior nasal cavity in the choana resulted in complete closure of the thin and fragile nasopharynx without tension at the suture site.

    Repair of CSF fistula at the nasopharynx. A rotation flap was made of the mucosa of the posterior nasal septum and floor at the choana, on the patient's right side. Then this flap was moved to the nasopharynx, resulting in a complete and tension-free closure of the mucosa.
