The purpose of this study is to describe a new technique for en bloc temporal bone resection using a diamond threadwire saw (T-saw) as an alternative to cutting the temporal bone with an osteotome. This technique has been performed in 10 patients with external auditory canal and middle ear cancers without any injury to the internal carotid artery or jugular vein. The authors conclude that the use of a diamond threadwire saw after transposing the internal carotid artery anteriorly is a safe, simple, and reliable technique for en bloc temporal bone resection.
Abbreviations used in this paper: IAC = internal auditory canal; ICA = internal carotid artery.
