The most common surgical complications of middle ear surgery are facial nerve lesions, meningoencephalocele. For stapes surgery they may concern the middle ear, the inner ear or the oval window. These complications may be prevented by a precise and oriented analysis of the preoperative imaging.  

1) Complications of middle ear surgery (cholesteatoma) 1.1 Facial nerve lesions 1.2 Meningoencephalocele 2) How to prevent these complications? 2.1 Facial nerve position Lowered VII-2 Dehiscent VII-2 canal, with or without inferior nerve herniation Anteriorized VII-3 2.2 Position of the sigmoid sinus 2.3 Height of the tegmen 2.4 Osteomatous otitis masking VII-2 or semicircular canal   3) Complications of stapes surgery (otosclerosis) 3.1 Middle ear Lateral displacement of the prosthesis Erosion of the long process of the incus 3.2 Oval window Perilymphatic fistula Hemorrhage (wound to a persistent stapedial artery) Granuloma/scarring tissue in the OW 3.3 Inner ear Pneumolabyrinth Intra vestibular displacement of the prosthesis or granuloma Infectious labyrinthitis Cophosis on Gusher ear 4) How to prevent these complications? 4.1 Position of the VII-2 4.2 Stenosis/congenital hypoplasia of the OW 4.3 Persistence of a stapedial artery 4.4 Associated inner ear malformations
