主　　题：Transcanal endoscopic approach Petrous cholesteatoma Glomus tympanicum Lateral skull base 

摘      要：Introduction:Majority of petrous bone and lateral skull base pathologies are benign in *** complex anatomy usually warrants an extensive approach with associated *** summary:Two cases of petrous bone cholesteatoma(1 congenital cholesteatoma with facial palsy and 1 acquired cholesteatoma)and a case of glomus tympanicum were treated with exclusive endoscopic transcanal *** cases of petrous cholesteatoma were addressed with trans-promontorial and infra-cochlear *** mean operative time was approximately 140 *** CSF otorrhoea was noticed in the post-operative *** average period of hospital stay was 3.7 ***:In the subset of cases with limited benign disease an endoscopic trans-canal approach is a better alternative to an external *** decreases operative time,blood loss,chance of meningitis,morbidity and hospital *** lack of depth perception is a major hurdle which can be come over by experience in endoscopic middle ear *** approach can create direct access to cochlea/petrous apex/internal auditory canal(IAC)/Supra-geniculate ganglion region.
