- Abstract
Congenital or acquired petrous bone cholesteatoma is defined as a cholesteatoma medial to the otic capsule that can lead to various complications, such as hearing loss, facial paralysis, headache or dizziness, and may represent a surgical challenge due to the extension in anatomical areas difficult to access. Materials and method. We present two cases of petrous bone cholesteatoma - supralabyrinthineapical, according to Moffat et al. classification - in which endoscope-assisted transmastoid supralabyrinthine approach was performed. In both cases, dizziness was present due to superior semicircular canal dehiscence. Results. The cholesteatoma was removed without complications and the residual hearing was preserved. Conclusions. Endoscope-assisted surgery allows the removal of cholesteatoma of petrous apex while preserving hearing. It also makes possible the removal of the cholesteatoma via transmastoid approach for perilabyrinthine space using minimally invasive surgery instead of middle fossa approach, which is the standard surgical procedure. Thus, the complications of craniotomy can be avoided.
