Objective:
To evaluate the clinical manifestation and surgical technique of Mondini dysplasia with cerebrospinal fluid (CSF) leakage.
Method:
Three Mondini dysplasia with spontaneous cerebrospinal fluid leakage were treated by the authors. A transcanal tympanotomy were used to pack the vestibular cavity with muscle.
Result:
Three children were first manifested with recurrent meningitis and spontaneous cerebrospinal fluid rhinorrhea. Further examinations found that the leakages were otogenic. One side or both sides Mondini dysplasia were confirmed by CT scanning of temporal bones. The leakages were all stopped by the primary surgical closure.
Conclusion:
Mondini dysplasia should be considered in children with spantaneous cerebrospinal fluid otorhinorrhea. A temporal bone CT scan can confirmed the diagnosis. A transtympanic closure is very effective in the management.
