Abstract

Objective:    Meningoencephaloceles of the temporal bone are rare entities. There are two main categories, congenital and acquired. Acquired meningoencephaloceles are more common due to iatrogenic injury to the tegmen tympani which is a common complication during mastoidectomy.


Case Presentation: We present a case of an idiopathic meningoencephalocele that was diagnosed and treated successfully during cochlear implantation via transmastoid approach. Fascia lata graft was used to reconstruct the deficit of tegmen tympani. Audiological outcome has been improved.


Conclusions: Idiopathic Meningoencephaloceles present without specific clinical symptomatology and as a result diagnosis delay significant. In literature, there are various surgical approaches with mixed results.
