Intraoperative view also revealed that longstanding compression to the trunk of the facial nerve had moved the division to temporofacial and cervicofacial branches far more anteriorly than expected, thus hampering dissection (Figure 2).
Through surgical exploration the lesion was found to be strictly adherent to the main trunk of the facial nerve and longstanding compression had moved the division to temporofacial and cervicofacial branches far more anteriorly than expected.
Within the gland it divides into temporofacial and cervicofacial trunks.
Divisions of the Facial Nerve: The trunks in all the specimens divided into main divisions: the temporofacial and the cervicofacial.
All the facial nerves had divided into two divisions the temporofacial and cervicofacial.
Extratemporally, the facial nerve separates into two main branches at the pes anserinus: the temporofacial
branch and the cervicofacial branch.
Minor complications include temporofacial
pain, headache, soft tissue swelling, facial numbness, mental status changes, groin pain and haematoma formation at the site of femoral vessels.
Relative to sinonasal tract RMSs, symptoms include nasal obstruction, epistaxis, pain, refractory otitis media, otorrhea, temporofacial
swelling or deformity, and neurologic deficits.
RESULTS: In this study all the 50 specimens (100%) had only one trunk(Fig1), two divisions, namely the temporofacial and the cervicofacial and five branches, namely the temporal, zygomatic, buccal, marginal mandibular and cervical.
But in 2 specimens (4%) the retromandibular vein was passed within a loop which was formed by the temporofacial division (Fig13).
