ABSTRACT
BACKGROUND:
Endoscopic transnasal approaches to the skull base have revolutionized the treatment of cerebrospinal fluid (CSF) fistulae, making repair less invasive and more effective compared with craniotomy or extracranial techniques.AIM:
This study evaluated, retrospectively, the results of endoscopic repair of dural defects with the use of mucoperiostal grafts taken from the lower turbinate. MATERIALS ANDMETHODS:
Between January 1997 and January 2007, 125 cases of anterior skull base CSF fistulae were treated endoscopically at the Instituto Felippu de Otorrinolaringologia, Sao Paolo, Brazil, and at the Department of Otolaryngology of the University Hospital "Ospedali Riuniti", Foggia, Italy. Fistula closure was achieved by overlay apposition of a lower turbinate mucoperiostal graft fixated with fibrin glue and Surgicell.RESULTS:
The etiology of the fistula was accidental trauma in 41 cases, iatrogenic trauma in 29, skull base tumour in 12, and spontaneous in 43. The site of the defect was the sphenoid sinus in 43 patients, the cribriform plate in 42, the anterior ethmoid roof in 21, the posterior ethmoid roof in 17, and the posterior wall of the frontal sinus in 2. The success rate at first attempt was 94.4%; the 7 cases of postoperative recurrent CSF leakage involved patients presenting with spontaneous fistula and elevated intracranial pressure; 5 of these had a body-mass index > 30 and 3 suffered from diabetes mellitus. DISCUSSION ANDCONCLUSION:
In our hands, the success rate of endoscopic fistula repair was high, even in defects larger than 2 cm. Success rates may be further improved with accurate diagnosis of elevated intracranial pressure, a contributing factor to failure of spontaneous fistula repair.
