摘要:
ObjectiveTo present an anteroposterior approach with split ear canal technique in severe malformed ears in which cochlear implantation is not possible through the standard facial recess approach.SettingThe operation was performed at Hacettepe University Medical Faculty, which is a tertiary care center.Study DesignCase report.PatientA 4-year-old female patient with severe Mondini malformation whose facial nerve was completely dehiscent and overlying the stapes and round window.InterventionThe anteroposterior approach was used, and the middle ear was entered after the tympanomeatal flap was elevated. The posterior wall of the ear canal was split longitudinally with a diamond drill. The electrode was inserted easily through the ear canal and then transferred into the mastoid.ConclusionThe anteroposterior approach with split ear canal method may be used if, during facial recess, the landmarks in the middle ear (stapes, stapedius tendon, round window, and promontory) cannot be identified clearly because of an abnormal facial nerve (coursing anteriorly, preventing the use of a drill). It is an alternative for the canal wall down procedure.
