ABSTRACT
The extratemporal course of the facial nerve distributes in facial mimic muscles in a complex pattern. The traditional depictions of five main branches without anastomoses are not common. Davis classification remains the gold standard in the classification of facial nerve branching patterns. During a routine dissection of an 74-year-old male cadaveric specimen, we detected a very rare anatomical variation. The zygomatic branch of the facial nerve was totally absent. The temporofacial division of the main trunk was bifurcated to a temporal and a buccal branch. The anterior temporal and posterior buccal branches formed a plexus to supply the orbicularis oculi muscle. This unique variability highlights the complexity of the extratemporal facial nerve course. Retrograde facial nerve dissection requires deep knowledge of every anatomical variation of the facial nerve course to avoid an iatrogenic injury.
