Anatomical Facial Nerve Findings in 209 Consecutive Atresia Cases

Abstract

Atresia repair remains one of the most challenging procedures in otology. In spite of modern preoperative imaging, the facial nerve remains at risk. When performing surgery on patients with preoperative facial nerve paresis and/or lower Jahrsdoerfer scores, the surgeon should be aware of a higher incidence of facial nerve abnormalities. Thorough knowledge of anatomical variations and meticulous surgical technique are mandatory to safely perform these surgeries.
