  • Title: Relationship of the temporofrontal rami of the facial nerve to the fascial layers of the temporal region.
    Author: O'Brien JX, Ashton MW.
    Journal: Ann Plast Surg; 2012 Jun; 68(6):547-8. PubMed ID: 22643100.
    Abstract:
    BACKGROUND: Historically, dissection of the temporoparietal fascia immediately above the zygomatic arch has been avoided due to the risk of transection of the temporofrontal rami of the facial nerve. METHODS: A total of 8 fresh cadaveric hemi-faces have been dissected to investigate the relationship of the temporofrontal rami of the facial nerve to the fascial layers in the temporal region. RESULTS: The relationship of the temporofrontal rami of the facial nerve to the fascial layers in the temporal region is variable, with some deep rami coursing below the parotid-temporal fascia and other superficial rami reaching the temporoparietal fascia before entering the lateral edge of the orbicularis oculi. CONCLUSIONS: Dissection of the temporoparietal fascia immediately above the zygomatic arch may place superficial branches of the temporofrontal rami at risk.
