摘　　要：Introduction:Majority of petrous bone and lateral skull base pathologies are benign in nature.The complex anatomy usually warrants an extensive approach with associated morbidity.Case 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 approach.The cases of petrous cholesteatoma were addressed with trans-promontorial and infra-cochlear approaches.The mean operative time was approximately 140 min.No CSF otorrhoea was noticed in the post-operative period.The average period of hospital stay was 3.7 days.Conclusion:In the subset of cases with limited benign disease an endoscopic trans-canal approach is a better alternative to an external approach.It decreases operative time,blood loss,chance of meningitis,morbidity and hospital stay.The lack of depth perception is a major hurdle which can be come over by experience in endoscopic middle ear surgery.This approach can create direct access to cochlea/petrous apex/internal auditory canal(IAC)/Supra-geniculate ganglion region. 关键词：Transcanal endoscopic approach Petrous cholesteatoma Glomus tympanicum Lateral skull base
