[Temporal bone surgery. Surgical sequelae and complications]

The saying "no surgery, no surgical complications" is certainly true for all specialties. Three categories of undesired events may occur following surgery: surgical sequelae, failure to cure and complications. A critical self-analysis of surgical complications often reveals that these arise in vexing fashion according to Murphy's law, i.e. "what can go wrong, will go wrong". Incomplete preoperative evaluation, insufficient exposure of the surgical field, failure to identify surgical landmarks and misjudgment of the patient's preoperative complaints may culminate in an undesired surgical outcome. Modern preoperative radiology, the possibilities of actual or even virtual temporal bone drilling in the laboratory and the surgeon's level of experience all ensure the relative rarity of relevant surgical complications in otology.
