Complications and their management in tympanomastoid surgery.
Chronic diseases of the ear and their surgical treatment can endanger the delicate structures of the temporal bone in close relationship with the middle ear. The experience and expertise of the otologic surgeon, based on perfect knowledge of the complex anatomy of the whole temporal bone, are unfortunately built up partly through the management of complications encountered in tympanomastoid surgery and may require knowledge of basic neuro-otologic procedures. Paralysis and paresis of the facial nerve and labyrinthine, and dural and vascular injuries may have consequences not only in the final result of surgery but also in endangering the patient's life. All major complications are discussed and some possible treatments are proposed. Minor complications affecting the temporomandibular joint, the dura, the external auditory canal, and the bony canal wall are also covered, along with some suggestions on how to keep these consequences within reasonable percentages.
