Objective: The aim of this study was to explored the possibility of using the Fallopian bridge technique for petrous bone cholesteatoma.Methodology: Complete canal-wall-down mastoidectomy was performed with an extended facial recess.The mastoid portion of the facial nerve inferior to the labyrinth was acompletely skeletonized, creating the "Fallopian bridge".Angled endoscopic visualization was advocated to enhance exposure.Surgical bone removal followed the bony destruction induced by the lesion.Translabyrinthine approach or transotic approach might be combined.Obliteration of the operative cavity with fat tissue and closure of the EAC were needed to prevent cerebrospinal fluid (CSF) leak.
