Clinical Treatment Research of Traumatic Cerebrospinal Fluid Leaks

[Objective]To understand the relation between skull base fracture spot and cerebrospinal fluid leaks, look for the effective method of treatment.[Methods]Seven hundred and sixteen cases of skull base bone fractures were admitted in 9 years . Cerebrospinal fluid leak rate was 24.6%(176 cases).[Results]Skull fractures occurred at anterior cranial fossa in 112 cases,at middle fossa in 46 cases,at both fossae in 18 cases.One hundred and fifty cases were cured after conservative treatment,26 cases were treated surgically.Twenty cases were cured by operation once,6 cases cured by operation twice.Among 26 surgically treated cases,10 were cooperated with ENT doctors.Rhinoscope and photograph system were used to repair the rhinorrhea.Ten cases,in whom 4 cases had failed transcranial repair,were successful in repair of rhinorrhea once with rhinoscope.[Conclusion]Skull base bone fracture spot and cerbrospinal fluid leak size decide the treatment plan choice.Surgery under rhinoscope has the advantage of minimal damage and accurate localization of fistula,so it can be used for cerebrospinal fluid rhinorrhea repair.
