Retrosigmoid Transmeatal Approach

An Anatomic Study of an Approach Used for Preservation of Hearing in Acoustic Neuroma Surgery and Vestibular Neurotomy


The limitations of the transmeatal phase of the retrosigmoid transmeatal approach are shown, and the problems of opening the internal acoustic meatus via this approach and the criteria for its use are discussed.
