[Cerebrospinal fluid leak after translabyrinthine approach in acoustic neuroma excision].
Cerebrospinal fluid (CSF) leak is one of the most dangerous complications that can arise in cases of acoustic neuroma removal. It increases the risk of meningitis, requires longer postoperative recovery and often requires revision surgery. A retrospective analysis was performed on all cases of acoustic neuromas which had undergone translabyrinthine surgery at the Gruppo Otologico, Piacenza, Italy, between April 1987 and December 1997, in the aim of finding the causes of postoperative CSF leaks. The causes found were high pneumatization of the temporal bone and improper execution of some surgical steps. The technique has presently been modified on the basis of the experience gained from cases of CSF leaks. By scrupulously applying these modifications, from July 1994 to December 1997, a total of 160 patients were consecutively treated using the translabyrinthine approach without a single case of postoperative CSF leak. Routine use of this modified technique can and must lower the percentage of CSF leaks after a translabyrinthine surgery to nearly 0%.
