Objective:
To investigate the best treatment of cerebrospinal fluid rhinorrhea.
Method:
A retrospective study of 45 consecutive patients who presented with CSF leak,was conducted. Forty-two patients were treated with transnasal endoscopic approach, three with double approach transnasal and extranasal. The fascia lata, the myoplasm, the free middle turbinate graft and the free inferior turbinate graft were used for fistula repairing. Four repair techniques as onlay technique, inlay technique, underlay technique and obliteration technique were used.
Result:
Postoperative follow-up lasted from 5 to 84 months. The overall success rate after the first operation was 97.8%. Three patients got meningitis,one patient got local infection in frontal sinus, but all of them were cured.
Conclusion:
In our study, The outcome was very good in endoscopic repair of a small fistula in anterior cerebrospinal, a fistula in dorsum delta and a fistula in slope with a free graft of autogenous. But it needed a perfect choose in operation approach, repair technique and graft material.
