Introduction posterior tympanotomy through facial recess (fr) is the conventional and most preferred approach to facilitate cochlear implantation, especially when the electrode is inserted through the round window. the complications of the fr approach can be minimized by proper understanding of the anatomy of the fr.
Mastoidectomy Facial Recess Approach And Cochleostomy Techniques The facial recess of the petrous temporal bone is a small recess in the posterior wall of the mesotympanum lateral to the pyramidal eminence and stapedius muscle origin. the upper mastoid portion of the facial nerve runs immediately posterior to it, giving it its name. medial to the pyramidal eminence is the sinus tympani. The facial recess (fr) is the route used in posterior tympanotomy to perform cochlear implantation surgery (1, 2). the major boundaries of the fr are the facial nerve (fn) and chorda tympani (ct). several major and minor complications of posterior tympanotomy and cochlear implantation have been described previously (3). The facial recess (fr) is the crucial landmark in posterior tympanotomy approach which is the conventional approach for cochlear implantation surgery. this work aimed to measure the facial recess width and length radiologically and correlate these measurements with the surgical measurements in cochlear implantation procedure. Material and methods. this is a retrospective review of records of 24children with bilateral profound sensorineural hearing loss and ome who were implanted during january 2011 to november 2014 in the department of otorhinolaryngology and head and neck surgery at the pla hospital, using one stage implantation via the facial recess approach and round window insertion.

The facial recess (posterior tympanotomy) is a triangular region delineated by the fossa incudis superiorly, the facial nerve posteriorly, and the chorda tympani anteriorly (figs. 4.1 and 4.2). anterior to the chorda tympani lies the annulus fibrosus of the tympanic membrane. after the external auditory canal is thinned out, drilling is evenly. Access to the middle ear from the mastoid is best achieved through a posterior tympanotomy (facial recess) approach. the facial recess is defined as the bone or air cell system occupying the space between the facial nerve medially, the chorda tympani nerve laterally, and the fossa incudis superiorly. the dimensions of the facial recess are.
